12 Guide to Using Parts List Information The Replaceable Parts List Index portrays a tree structure with the major items being left most in the index. The example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of materials table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the Replaceable Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level below the Transmitter and implies that they are used in the Transmitter. The Controller Board is indented one level below the Control Cabinet so it will show up in the bill of material for the Control Cabinet. The tree structure of this same index is shown to the right of the table and shows indentation level versus tree structure level. Example of Replaceable Parts List Index and equivalent tree structure: Replaceable Parts List Index Part Number Page Table 7 1. Transmitter Table 7 2. Control Cabinet Table 7 3. Controller Board Table 7 4. PA Cabinet Table 7 5. PA Amplifier Table 7 6. PA Amplifier Board Table 7 7. Output Cabinet Control Cabinet Controller Board Transmitter PA Cabinet PA Amplifier PA Amplifier Board Output Cabinet The part number of the item is shown to the right of the description as is the page in the manual where the bill for that part number starts. Inside the actual tables, four main headings are used: Table # #. ITEM NAME PART NUMBER this line gives the information that corresponds to the Replaceable Parts List Index entry; PART NUMBER column gives the ten digit Harris Broadcast part number (usually in ascending order); DESCRIPTION column gives a 25 character or less description of the part number; REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102, etc.) that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the schematic) or 2) gives added information or further explanation (i.e., Used for 208V operation only, or Used for HT 10LS only, etc.). NOTE: Inside the individual tables some standard conventions are used: A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column means that this item is used on or with C001 and is not the actual part number for C001. In the ten digit part numbers, if the last three numbers are 000, the item is a part that has been purchased and has not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured or is purchased from a vendor and modified for use in the Harris Broadcast product. The first three digits of the ten digit part number tell which family the part number belongs to for example, all electrolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found to have a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been modified in some manner at the factory and will therefore show up farther down into the individual parts list (because each table is normally sorted in ascending order). Most Harris Broadcast made or modified assemblies will have 9xx xxxx xxx numbers associated with them. The term SEE HIGHER LEVEL BILL in the description column implies that the reference designated part number will show up in a bill that is higher in the tree structure. This is often the case for components that may be frequency determinant or voltage determinant and are called out in a higher level bill structure that is more customer dependent than the bill at a lower level.

16 1 2 Section-I Introduction 1 2 General Information The MSC (multi system controller) uses a micro based control board and has a user friendly operator interface. The MSC is housed in a standard 1 RU assembly. The MSC can be installed in a typical 19" (482.6 mm) wide equipment rack. Note RU refers to rack unit which is a measurement of the height of the device; 1RU = mm (1.75 in). The MSC controller can operate on any single phase voltage from V AC, 50/60 Hz. Figure 1-1 MSC Front Panel Figure 1-2 MSC Rear Panel The MSC is not a comprehensive transmitter controller; it does not adjust/regulate RF power output levels, or perform foldback functions, etc. These functions are handled by each transmitter s control system. The MSC is designed to interface with Harris Broadcast radio and TV transmitters. The MSC, shown in Figure 1 1, is a versatile controller capable of operating in three different modes: DualTran Mode Main/Alt (1+1) Mode: N+1 Mode DualTran Mode: MSC operation in DualTran mode controls two transmitters, each operating at the same frequency, using a common RF drive source. The power from each transmitter is combined into a single RF output. DualTran transmitters are designated as transmitter A and transmitter B. The MSC, with a properly designed RF combining system, can provide automatic 1/2 power bypass by routing the full output of either transmitter directly to the antenna, while the output of the faulted off transmitter is routed to the combiner reject load. The faulted off transmitter can then be manually turned on and tested into the reject load without affecting operation of the on air transmitter. 1+1 (main/alternate) Mode: MSC operation in 1+1 mode controls two transmitters, each operating at the same frequency, one transmitter operates as the main transmitter and the other as the standby transmitter. Failure of the main transmitter will cause the MSC to switch the system to the standby transmitter. N+1 Mode: N+1 is the most common MSC mode. The MSC can control up to eight main transmitters plus one reserve transmitter in an N+1 system. N+1 operation allows configuration of multiple transmitters, operating at different frequencies, with a single, frequency agile, reserve ("+1") transmitter. The transmitter RF outputs are switched with minimum delay; the switching delay depends on individual transmitter requirements. The MSC (N+1 mode) controller also routes the desired program (audio or transport stream ASI/SMPTE 310) to the reserve transmitter when it is brought into service to replace a faulted off transmitter. During N+1 operation all transmitters are switched to remote mode, thus passing their control to the MSC. Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

17 Multi-System Controller Section-II Installation 2 1 Introduction This chapter contains information for the installation of the Harris Broadcast Multi System Controller (MSC). Installation and turn on sequence is similar in most MSC configurations. MSC system often include a control rack, RF system, switch matrix, program input switcher(s), and RF load. Variations between configurations exist and the descriptions that follow may not pertain to all systems. Refer to technical manuals for equipment such as transmitter, exciter, switcher, router, and RF system for additional installation instructions. 2 2 Unpacking Carefully unpack the MSC and associated equipment. Perform a visual inspection to ensure that no damage was incurred during shipment. Retain the shipping material until it has been determined that equipment is undamaged. The contents of the shipment is described in the packing list. If the contents are incomplete or if the unit is damaged electrically or mechanically, notify the carrier and Harris Broadcast Solutions. 2 3 Operating Environment The selection of a proper installation location is essential for equipment longevity and reliability. Do not install the transmitter in places where it may be exposed to mechanical shocks, excessive vibration, dust, water, salt air, or corrosive gas. Ambient temperature and relative humidity should always range between the following limits at the installation location: Ambient temperature: 0 to +50 o C Relative humidity: 5 to 95% non condensing Note Transmitter environmental specifications may vary. Refer to the specific transmitter technical manuals for more additional information. 2 4 System Installation Prior to installation, this technical manual and the appropriate transmitter and exciter technical manuals should be carefully studied to obtain a thorough understanding of the principles of operation, circuitry and nomenclature. This will facilitate proper installation and initial checkout. Caution ALL CONNECTIONS REFERRED TO IN THIS INSTALLATION PROCEDURE SHOULD BE VERIFIED USING THE SCHEMATICS SUPPLIED WITH THE SYSTEM. THE SCHEMATICS SHOULD BE CONSIDERED THE MOST ACCURATE IN CASE OF DISCREPANCY WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

18 2 2 Section-II Installation Review all drawings in the transmitter and system drawing packages. The drawing package(s) may contain several configurations. Find the configuration that is closest to the configuration desired. The following information is general in nature and may vary with transmitter type and number. The MSC can be used with radio or TV transmitters. Most installations will be similar to these examples. The MSC and transmitter system installation may be accomplished in the following order: 1. Transmitters and Control Rack Placement 2. Load Placement 3. RF Switch Matrix 4. System Wiring 5. Grounding 6. AC Power Installation 7. External Interlock Connection 8. Program Signal(s) Wiring 9. Initial Checkout. Note Racked systems may be shipped with many components in place and wired Transmitters and Control Rack Placement Low power systems may have up to four transmitters plus the MSC in one equipment rack. Higher power systems could have each transmitter in a separate cabinet, or cabinets, with the MSC and other peripheral equipment mounted in a separate rack. Higher power system transmitter cabinets and control rack should be placed together, in one area, on a level surface, near power and signal cables. Access to the front and rear of the transmitters is required. The floor must be capable of supporting the combined load of the transmitters and control racks. (refer to transmitter outline drawing for transmitter specific information). Transmitters should be placed side by side in a straight line if possible. This will be helpful for interconnecting control/signals cable and allow simpler alignment of transmission line/switch matrix parts. Place transmitters according to the overall layout drawings. Routing of control cables will be done through the inter cabinet holes on top of the transmitter cabinets. The transmitters are individually marked with a number and the reserve transmitter is identified as such. The transmitters were tested in the Harris Broadcast factory for a particular function and frequency. They should be placed in order according to the drawings. If changes are made to this arrangement, wire lengths, wire markings, transmission line, and the controller setup may not work as tested. The control rack, if purchased, should be placed as shown in the system specific documentation. The cable lengths are designed for that placement. If a control rack is not provided, the controller and program switcher (if present) must be placed in a rack or on a table top near the left side of the reserve transmitter (as viewed from the front in an N+1 system). Dual systems are typically configured with transmitter A to the left of the control cabinet and transmitter B to the right. Control and signal cables may be extended but provisions for extension are not provided Load Placement Refer to the system installation drawings (layout, interconnect, etc.) to determine recommended load placement. The load may be hung from the ceiling, placed further away with addition line, or placed on a stand. Placement of the load on top of a transmitter cabinet is not recommended. The load interlock cable (if load is interlock equipped) is 30 feet in length to accommodate alternate placements of the load. In some transmitters the load may be installed in the transmitter racks.

19 Multi-System Controller RF Switches External RF switches (if located near the top of the transmitter cabinets) need to be placed in a specific order for ease of installation. RF switch #1 should be placed with the elbow assembly for transmitter #1. RF switch#2 should be placed with the elbow assembly for transmitter # N+1 Switch Control (MSC RF Switch) N+1 and DualTran systems use a switch control module assembly. The switch control module uses an Ethernet port to interface to the MSC. The switch control module is the interface between the MSC and RF switch I/O. Figure 2 1 is a simplified diagram of an N+1 system using two main transmitters, one reserve transmitter and two RF coax switches. Configurations for specific N+1 or DualTran systems may vary.

Figure 2-3 N+1 Ethernet Connection Diagram WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

22 2 6 Section-II Installation Antenna and Load Interlock Connections The antenna and load interlock connections are made on the MSC switch module. J18 is the antenna/load interlock connector. The antenna interlock and load interlocks are two separate circuits. The RF switch module may ship with jumpers placed between pins 1 and 2 (load interlock) and 6 and 7 (antenna interlock) on J18. These jumpers complete the interlock circuits allowing the transmitter to operate. Removing a jumper opens the interlock circuit preventing the transmitter(s) from producing RF. Note The test load interlock jumper may be connected at the factory. To use the antenna interlock connection, remove the jumper between terminals J18 6 and J18 7(GND) on the MSC switch module located in the MSC rack and connect the load interlock wires to pins J18 1 and J18 2. Refer to the system interconnect drawings. Note: In this N+1 system example, if the antenna interlock is open, both main transmitters will not operate. An open load interlock will not affect the on air transmitters feeding RF to the antennas. Note When fault-off interlock circuits are used each transmitter will require an on command after an interlock closure is restored System Wiring In multiple cabinet systems, control cables can be routed to the top of the transmitter cabinets. Holes in the top of the cabinets allow cables to run from one transmitter cabinet to the next. When passing cables from cabinet to cabinet place a protective cover on the edges of holes that cables pass through. This will prevent long term wear of wire insulation. During the factory system test, system cables are connected and then partially removed for shipment. System cables may still be connected at one end. Each cable is marked with its destination near the connector. More detailed cable routing information is available in the drawing package. The overall connection diagram is best used during the installation process. Cables are of sufficient length for some versatility. Cables may need to be coiled or routed differently to use up extra length. The MSC easily interfaces to transmitters via Ethernet connections provided on many transmitters. Figure 2 3 illustrates N+1 interface connections including RF switch control AC Power Installation Refer to the System Outline Drawing in the transmitter drawing package for transmitter current ratings, nominal fuse sizes and suggested wire gauge for the transmitter input voltage. All AC input wiring should be in agreement with applicable electrical codes and capable of supplying the equipment power requirements. Note Customer supplied AC primary power disconnect, or a means to completely de-energize parts of the system s primary circuit for servicing, is necessary. AC must be provided to the MSC (or controller rack) and program input switcher if not included in a pre wired in a rack. If a controller rack is supplied, AC will need to be supplied to the AC power control panel. See documentation for the AC power control panel for the particular transmitters being used. If a rack is not supplied, the MSC must be supplied with AC power. The MSC has an auto ranging nominal AC input between 120 and 240 Volts AC, 50/60 Hertz. No AC switching is required. The program input switcher(s) may be provided with auto range, 120 or 240 Volt AC input rating. Measure the supply voltage to be sure that the only the proper voltage is applied to this unit. Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

23 Multi-System Controller 2 7 The load, if supplied and equipped with a built in blower, must be supplied with AC voltage as identified on the nameplate. Low power loads, below 5kW, usually do not have blowers and therefore do not need AC voltage. See load manual and nameplate on load for confirmation. Higher power RF coax switches must be supplied with AC voltage as identified on the switch itself. Lower power systems may not require AC for the RF switches. They may use a 12 or 24 VDC voltage supplied by an antenna matrix switcher board Ground Requirements Two separate ground connections are required for system components: an AC safety ground and an RF earth ground. The AC safety ground prevents an electrocution hazard should a dangerous potential from inside the unit accidentally contact the metal chassis. The AC safety ground works by providing a secure, uninterrupted path for any wayward electrical current to return to the source: the secondary winding of the local power grid transformer (or generator). This ensures that any exposed metal parts will not simply float to a voltage level dangerous to humans in the case of an accidental contact with mains voltage and that a sufficient fault current will be drawn to trip any circuit protection devices. The AC safety ground connection is made automatically for components that plug in to the AC supply via the green/yellow wire (third prong) of the AC input cord. In the case of a Harris Broadcast supplied AC distribution chassis, the green/yellow physical earth (PE) connection from the incoming AC mains service terminates at the PE terminal of the AC distribution chassis. The individual subassemblies making up the transmitter connect via the green/yellow wire of their mains cords to the same PE terminal on the AC distribution chassis. When present, the rack buss bar will also connect to this PE terminal. The AC safety ground (green/yellow) wire from the transmitter rack should terminate at a suitable physical earth (PE) or (PEN) connection at the AC mains entrance/distribution panel, or as otherwise dictated by safety norms. In those systems with only a direct earth ground instead of a wired PE connection back to the power source, the use of special ground fault sensing circuit protection devices is indicated. In addition to the equipment chassis, all metal enclosures and conduit pieces potentially exposed to mains voltages in the case of a fault should have a secure, uninterrupted, conductive path back to the PE terminal in the mains entrance. The RF earth ground prevents damage to the equipment during lightning induced transients by providing a low impedance path for lightning to return to the earth. An RF ground strap/wire attachment point is located at the rear of the transmitter chassis. This connection is suitable for use in a single point grounding system, with the ground strap attached to the equipment rack and the rack, in turn, to a common grounding plate. A strap with a minimum width of five (5) cm should be used to connect the equipment rack to the building earth ground system Surge Suppression Devices Harris strongly recommends the use of surge protection devices on the incoming AC mains lines. These devices protect against damages due to transients arising from both natural and man made sources. (e.g. lightning and inductive load switching). Clear preference is to be given to "series" type surge protection devices featuring protection by both a series inductance / shunt capacitor filter and shunt threshold device over simple shunt only clamping devices. The surge protector must be sized to handle the full amperage of the load it is protecting (plus a nominal safety margin) and be connected to the building ground system by short, direct connections. In the case where the shunt protection elements are protected by a fuse, it is necessary to periodically check the integrity of the fuse to ensure continued transient protection. The transmitters and other components are often equipped with a level of protection, but this protection has its limits, and it is prudent to protect your investment by installing quality surge suppression equipment. Caution FAILURE TO FOLLOW THESE RECOMMENDATIONS MAY LEAD TO SHORTENED EQUIPMENT LIFE AND REDUCED RELIABILITY WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

24 2 8 Section-II Installation Program Input Switcher Connections The MSC system may use program (or digital transport stream) switcher to route the required sources to a reserve transmitter as needed. The switcher (also called the input switcher) is controlled by the MSC unit. An RS 232 null cable with 9 pin D connectors is used to connect the input switcher to the MSC COM 3 input located on the back panel. Programming must be routed from each source to the input switcher and to each main transmitter/ exciter input. The output of the switcher goes to the reserve transmitter/exciter input. See Figure 2 4 for a typical N+1 switcher wiring diagram. Note It is assumed that each program source has dual outputs. If only a single output is available, those outputs need to be fed to distribution amplifiers with multiple outputs. This allows direct feeds to each transmitter and to the input switcher. Refer to the wiring diagram in the system doc package for detailed information.

28 2 12 Section-II Installation 2 6 Initial Checkout Once the system is fully assembled, apply AC to one piece of equipment at a time to be sure it is operable. Refer to the transmitter manuals for initial turn on procedures for each transmitter. Once the transmitters are powered up, they will be in standby mode until each transmitter on button is pressed. The MSC power switch is located on the rear of the chassis, next to the AC power plug (refer to Figure 1 2, on page 1 2). The initial on screen should appear as shown in Figure 2 6. With AC applied to all equipment, set up and check out may begin. Figure 2-5 MSC Initial Turn-on screen During MSC initial start up, the four LEDs left of the LCD display are off. MSC start up takes about thirty seconds. When the Main Menu screen appears, some of the LEDs will illuminate green (depending on the programmed settings). The Fault LED may illuminate red since the transmitters haven t been turned on and possibly program input signals are not yet present. Once the Main Menu screen appears, as shown in Figure 2 6, the system is ready for operation. Figure 2-6 MSC Main Menu Section 3 discusses operation and explains how to use the front panel buttons to navigate the MSC LCD screens. It also describes GUI screen navigation and setup for specific system configurations. Please read Section 3 before operating the system. Caution BEFORE PRESSING A TRANSMITTER ON BUTTON CONFIRM THAT THE TRANSMITTERS ARE PROPERLY CONNECTED TO KNOWN GOOD COMBINERS, ANTENNA SYSTEMS, OR LOADS. THE ANTENNA AND LOAD INTERLOCK CIRCUITS MUST ALSO BE INSTALLED AND CONFIRMED. The configuration of an N+1 system normally consists of main transmitter #1 routed to antenna 1 (or combiner), main transmitter #2 routed to antenna #2 (or combiner), and the reserve transmitter routed to the test load. The main transmitters (there could be more than two) will operate at different frequencies Configuration of a 1+1 or Main/Alt system consists two transmitters (operating at the same frequency) with one acting as a main routed to the antenna and another in reserve as an alternate. Configuration of a DualTran system consists two transmitters (operating at the same frequency) that are combined into a common RF output and capable of operating either of the transmitters into the load or antenna. Confirm transmitter set up and operation by turning each main transmitter on by pressing the individual transmitter s On button. RF output power will ramp up. As the main transmitters ramp up to their rated power into antennas (or combiner), the ON LED, next to the MSC display, will illuminate green. Note In some cases, depending on transmitter type, modulation type, or system configuration, if there is no program input to the reserve transmitter, pressing the ON button will not result in RF output unless a test mode in the reserve transmitter is activated. Turn both main transmitters OFF by pressing the OFF buttons. Proceed to Section 3 for system setup and detailed operation information.

The MSC screen will revert back to the TX 1 Ctrl/Status screen immediately after the transmitter turns on. Note You will experience some lag time when pressing the power raise and lower buttons and seeing the results on the display. This is normal. Use discreet button presses to raise and lower power. The internal controller is monitoring all of the critical functions of the transmitter while the raise/lower functions are being performed to insure all parameters are within normal limits. Caution USE DISCREET BUTTON PRESSES TO RAISE OR LOWER POWER. DO NOT HOLD IN THE RAISER OR LOWER BUTTONS FOR EXTENDED PERIODS AS THIS MAY RESULT IN POWER OVERSHOOTS. STEP 6 STEP 7 STEP 8 STEP 9 Press the " " button to reopen the On/Off screen. Use the up down arrows to select OFF and press the " " button to turn the transmitter off. Repeat the above steps to turn Transmitter #2 and then the reserve transmitter on and off. End of procedure. Note Depending on transmitter modulation and system configuration, if there is no program input signal applied to the transmitter, pressing the On button may not produce RF output. In these cases, a test signal may need to be activated in the exciter. Refer to the transmitter or exciter manuals for the settings needed to produce RF output Auto Mode System Test Use the following procedure to test auto operation of the MSC N+1 system. STEP 1 Confirm that valid transport streams are being fed to main transmitters and to the input switcher (s). Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

71 Multi-System Controller 3 43 STEP 2 STEP 3 STEP 4 Turn the main transmitters on using the transmitter front panel On buttons. Allow a few seconds for the transmitters to ramp up to full power. Use each transmitter s Raise/Lower buttons to adjust the RF output to full rated power. Verify that main transmitters are operating at full rated power into their antenna(s). The MSC On and Auto LEDs should be OFF. Each transmitter has its own control system that allows it to function as an independent transmitter system. Each transmitter has remote control Enable and Disable front panel control buttons. The transmitter remote settings must enabled to allow MSC control of the transmitters. Engaging the transmitter s remote Disable button will prevent MSC control of the transmitter. Remote status monitoring is available in either remote enable and disable modes. STEP 5 Use the instructions provided in "3 6 2 MSC System Auto/Manual Mode Selection" on page 3 41 to place the MSC into Auto mode. The Auto LED should now be lit Green. Note If the MSC was purchased as part of a total system, the RF trip level and trip time settings were preset at the factory. The MSC will not initiate a switch until the preset trip time has elapsed. A typical trip time setting for an N+1 transmitter is 10 seconds; when a fault occurs, 10 seconds will elapse before switching will begin. Check the trip level and trip time settings by navigating to the Transmitter Setup GUI screen ( "Figure 3-27 MSC Main/Alt Transmitter Setup Screen" on page 3-26) or follow the steps starting in "3 6 6 Setting Trip Time" on page 3-45 which use the LCD control buttons. Note Failure to properly set trip levels and switch travel times may result in nuisance trips that disrupt operation. If the MSC has not been configured in the factory set the RF trip level, trip and travel times before proceeding. STEP 6 Use the instructions provided in "3 6 1 MSC On/Off Selection" on page 3 41 to turn the MSC on. The On MSC On LED should now be lit green. Turn Transmitter #1 off at the transmitter. The MSC will detect the off condition and perform the following: Route the program signal fed to transmitter #1 to the reserve transmitter via the input switcher. Route the RF output of the reserve transmitter to transmitter 1 s RF output path by rotating RF transfer switch via the switch control board. Route the RF output of transmitter #1 to the load. Send an ON command to the reserve transmitter. STEP 7 The reserve transmitter will ramp up to its pre set power. The Raise/Lower buttons can be used to adjust the reserve transmitter s power to a specific power level as required. Note The Fault LED on the MSC panel will now be lit red to indicate a fault occurrence has placed the reserve transmitter on the air. Note UAX and ULX reserve transmitters will come up to required power levels without operator intervention since the reserve transmitter has been calibrated to levels required by each main transmitter. The following steps return the system to its original operating mode in order to repeat the same test for transmitters 2 N as desired WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

72 3 44 Section-III Operation Note Turning transmitter #1 back on at this point will not cause the MSC to switch transmitter 1 back to its antenna and on-the-air. It will power up into the load. Transmitter 1 has to be manually switched back to its antenna. The system was designed this way for safety reasons. STEP 8 STEP 9 STEP 10 Turn Transmitter 1 back on via the front panel.

Select the next main transmitter on the Transmitter Config screen. When completed, press the X button as needed to return to the Main menu Setting Main Transmitter Priority The MSC allows the user to prioritize main transmitters by relative importance. If multiple main transmitters faultoff, the MSC will compare priority levels on failed transmitters and place the reserve transmitter on air in place of the failed transmitter with the highest priority. If a second failed transmitter is programmed to have a higher priority than the first failed transmitter, the MSC will switch the reserve transmitter to take the place of the transmitter with the highest priority. The output of the highest priority failed main transmitter will be routed to the load. The output of any remaining failed transmitters will be routed to their antennas. The MSC was designed to send an on command to failed transmitters that are routed to antennas. This logic (in auto mode), allows continued operation of faulted transmitters, but possibly at a reduced power levels. If these lower priority transmitters cannot achieve an on air state, they will remain off and the MSC will take no further action. Note The use of auto verify (see Figure 3-37 on page 3-36) and auto restore (Figure 3-38 on page 3-37) will also affect the MSC operation based transmitter priority. Note Setting more than one main transmitter to the same priority number will cause the reserve transmitter to take the place of the main transmitter that faults first.

87 Multi-System Controller Auto Mode System Tests Use the following procedure to test auto operation of the MSC DualTran system. There are two types of combiner systems used. Switched and switchless. The operation of the MSC controller varies depending on which type of combiner is selected. Each transmitter has its own control system that allows it to function as an independent transmitter system. Each transmitter has remote control Enable and Disable front panel control buttons. The transmitter remote settings must enabled to allow MSC control of the transmitters. Engaging the transmitter s remote Disable button will prevent MSC control of the transmitter. Remote status monitoring is available in either remote enable and disable modes. If the MSC was purchased as part of a total system, the RF trip level and trip time settings were preset at the factory. The MSC will not initiate a switch until the preset trip time has elapsed. A typical trip time setting for an DualTran system is three (3) seconds; when a fault occurs, three (3) seconds will elapse before switching will begin. Check the trip level and trip time settings by navigating to the Transmitter Setup GUI screen ( "Figure 3 44 MSC DualTran Transmitter Setup Screen" on page 3 51) or follow the steps starting in "3 8 6 Setting Trip Time" on page Switchless System: STEP 1 STEP 2 STEP 3 Apply a system on command from the MSC controller, or the GUI screen. Both transmitters should be operating at their rated power. The combined power should be at nominal system power. Place the system in "AUTO" from the MSC controller or the GUI screen. Remove RF power from transmitter A by turning off the IPA circuit breakers inside the transmitter cabinet. The MSC will detect the power has dropped below the system low trip level threshold setting and perform the following functions: a.after the delay time set in the System Trip Time field, the controller will issue a command to the combiner to move the phase shifter to the B AIR mode. b. In B AIR mode, transmitter A is routed to the combiner reject load. Transmitter B is routed directly to the antenna. c.the MSC mode control is set to the manual mode. d. When the phase shifter(s) has reached the commanded to B AIR position, the controller will turn off the (faulted/failed) transmitter. Repeat the above procedure, but remove power from transmitter B, to verify that transmitter A is routed to the antenna and the B transmitter is turned OFF. Switched System: STEP 1 STEP 2 STEP 3 Apply a system on command from the MSC controller, or the GUI screen. Both transmitters should be operating at their rated power. The combined power should be at nominal system power. Place the system in "AUTO" from the MSC controller or the GUI screen. Remove RF power from Transmitter A by turning off the IPA circuit breakers inside the transmitter cabinet. The MSC will detect the power has dropped below the system low trip level threshold setting and perform the following functions: a.after the delay time set in the System Trip Time field, the controller will issue an off command to both transmitters. b.the MSC controller then issues a command to the combiner to move the switches to the B AIR mode. c.once the switches are in position and correctly reported their new B AIR mode positions, the MSC controller issues an on command to Transmitter B. d.the MSC mode control is set to manual mode. e.after testing the Auto switching in both directions, return the system back to normal operation WARNING: Disconnect primary power prior to servicing.

88 3 60 Section-III Operation Setting System Low Trip Level The following procedure outlines setup of system low trip level. The trip level will cause the MSC to automatically switch to 1/2 power bypass mode if the system RF output power drops below the low trip level. The trip level may be preset at the factory if the MSC was purchased as part of a complete DualTran system. The trip level can be set using the System Threshold GUI screen, see Figure 3 50 below and Table 3 37 on page 53 for details. Figure 3-50 MSC DualTran Thresholds Screen The following procedure describes use of the GUI to change the system low trip level. The trip level should be set to maintain maximum power to the antenna. Typically, this would be just below the output power of one transmitter. STEP 1 Log in to the GUI and navigate to DualTran Home>Service>System Setup>Thresholds to open the System Threshold screen (see Figure 3 50). STEP 2 Select System Low Trip Lvl entry box and enter the desired trip level in W. STEP 3 Use mouse or a finger press on another entry box to accept the new value. The trip level setting shown in Figure 3 50 is set to 3900 watts. If the system RF output power drops below 3900 watts, the MSC will switch to 1/2 power bypass mode if operating in auto mode. Note A low trip level equal to 45% of rated power output is typical. STEP 4 End of procedure. Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

89 Multi-System Controller Setting Trip Time Trip time is the allocated amount of time the user allows the combined system to operate below the low level point trip point before the MSC switches to 1/2 power bypass. Trip time may be set at the factory, but can be changed as needed. The trip time is set on the System Threshold GUI screen (see Figure 3 50 on page 3 60). The following procedure describes use of the GUI to change the trip time. STEP 1 STEP 2 STEP 3 Log in to the GUI and navigate to DualTran Home>Service>System Setup>Thresholds to open the System Threshold screen (see Figure 3 50 on page 3 60). Select System Trip Time entry box and enter the desired trip time in seconds. Use mouse or a finger press on another entry box to accept the new value. The trip time setting shown in Figure 3 50 on page 3 60 is set to 10 seconds. If the system RF output power drops below the low level for more than 10 seconds, the MSC will switch to 1/2 power bypass mode (if it is operating in auto mode). Note A trip time of three seconds is typical. STEP 4 End of procedure. Note Setting the trip time to a low value that initiates frequent switch overs will cause premature wear on RF transfer switches. Trip times of less than 3 seconds are not recommended WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

90 3 62 Section-III Operation Setting the Combiner Travel Time Combiner travel time is the amount of time allocated for the RF transfer switch or phase shifter to change positions before the transmitter becomes operational in high power bypass mode. Combiner travel time is set on the System Setup GUI screen (see Figure 3 45 on page 3 52). Some phase shifters take up to 30 seconds depending on the mode of operation. STEP 1 STEP 2 STEP 3 Log in to the GUI and navigate to DualTran Home>Service>System Setup to open the System Setup screen (see Figure 3 45 on page 3 52). Select Combiner Travel Time entry box and enter the desired travel time in seconds. Use mouse or a finger press on another entry box to accept the new value. The combiner travel time setting shown in Figure 3 45 on page 3 52 is set to 22 seconds. If the system RF output power drops below the low level trip point, for longer than the trip time setting, the MSC will switch to 1/2 power bypass mode during the time set for combiner travel time. Switched systems will be off air during the combiner travel time. Switchless systems will remain on air during while the phase shifters change positions.press the X button as needed to return to the LCD Main Menu screen. STEP 4 End of procedure Setting the System Low Warning level The system low warning is a setting used to warn user that RF output power has dropped below a preset level. This level can be the same as the trip level or it can be set at a higher level to act as a warning when RF output power approaches the trip level threshold (where a transmitter switch action will occur). The factory typically sets the trip warning threshold at the same point as the trip level threshold. The trip warning level can be set on The trip time is set on the System Threshold GUI screen (see Figure 3 50 on page 3 60). STEP 1 Log in to the GUI and navigate to DualTran Home>Service>System Setup>Thresholds to open the System Threshold screen (see Figure 3 50 on page 3 60). STEP 2 Select System Low Warning Level entry box and enter the desired level in W. STEP 3 Use mouse or a finger press on another entry box to accept the new value. STEP 4 End of procedure. The above low warning level may be set to the same value as the trip level.when the low trip warning level is reached the MSC will issue a system low warning Setting MSC Remote Enable/Disable Before leaving the transmitter facility, check to make sure the MSC remote is enabled and that all LED and icons on GUI home page are green.

93 Multi-System Controller Section-IV Theory 4 1 Introduction This section provides a simplified overview of the internal structure of the MSC. The core component of the MSC is a reliable SBC (single board computer). There are no user replacement parts on this board. It is beyond the scope of this manual to go into detail describing how this computer board works. There are key customer advantages in employing this SBC. These include: interfacing with other equipment is quick, simple, and standardized; software driven architecture allows user friendly operation, easy programming via front panel buttons, quick access to status of any part of the transmitter system, easy to upgrade software, simple IP interface to allow system remote control capability by another pc, and can be easily re configured to control additional transmitters etc Overview In the past, N+1, Dual Controllers, and Main/Alt controllers consisted of different hardware/software combinations. Configuration changes were accomplished by moving jumpers on circuit boards and changing DIP switch settings. The MSC is a software driven device that is user programmable to accomplish all tasks. No internal jumpers or switch settings are required. The MSC uses a single board computer (SBC) and communicates to device(s) via IP (internet protocol). For legacy products that do not have IP capability, a separate Ethernet to IO module is required. Figure 4 1 shows the single board computer (SBC). Figure 4-1 Single Board Computer The MSC is a one (1) rack unit (RU) assembly with a 20 X 4 LCD with keypad for local control/monitoring/ configuration. The LCD is controlled via USB from the SBC. The front panel also has four LED s: System ON (Green) System Auto (Green) System Remote Enable (Green) System Fault (RED) The MSC has two RJ45 connections on the back panel for WAN and LAN. Also included are two RS232 ports and four USB ports. The USB ports are not used as of this printing. The SBC allows communication to be done via IP. On board configuration software is via RS232. All communications from the MSC to IP devices are done on LAN networks to ease setup. A network switcher is added to the system allowing the MSC to control multiple transmitters, an antenna matrix switcher, etc WARNING: Disconnect primary power prior to servicing.

94 4 2 Section-IV Theory N+1 Sequence of events. If the N+1 system is in auto, the SBC will monitor data from the main transmitters. If one of the main transmitter s output power drops below the set threshold or loses communications, a switch over will take place. The SBC switch over procedure is programmed as follows: OFF command will be sent to the main transmitter (via LAN) and the +1 (reserve) transmitter.the interlock will be opened via the RF switch control. A 500mS pause occurs to wait for power to bleed down. The SBC sends a switch command to the RF switch control to route the reserve transmitter to the faulted main transmitter s location and route the main transmitter to the load. The SBC sends an program switch command to now route program signals from the faulted transmitter to the reserve transmitter. The SBC sends frequency, calibration, and exciter configurations to the reserve transmitter. A pause occurs for the RF switch control to reconfigure (user programmable, three seconds typical) The SBC sends an on command to the reserve transmitter and RF switch control closes interlocks. SBC sends off command to transmitter now into load via LAN. The Fault LED on the front panel illuminates red indicating a switch has occurred. Note Only affected transmitters are interlocked and turned off. Unaffected transmitters in larger N+1 systems remain on air. 4 2 SBC Software The SBC uses LINUX (Debian) OS software which is upgradable in the field. Upgrade is done using MSC software management screens (see Figure 3 24 on page 3 23). The SBC gathers data from other devices via TCP/IP. It stores data in a file location that can not be overwritten. All configurations will still be present after an Upgrade of software. Communication => TCP/IP using HTML Communication Speed => 10/100/1000 The SBC has SNMP V1, V2, and V3. It is able to port forward requests to devices on the LAN Network. When the MSC is in remote enable mode, remote control of devices is accomplished via the LAN. The SBC contains two (2) LAN devices: LAN 1 is the WAN, used for single point contact. LAN 2 used for all devices that need to communicate to the SBC for different Applications. Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

95 Multi-System Controller Section-V Maintenance 5 1 Introduction This section discusses MSC maintenance topics. The MSC requires minimal routine maintenance; there are no periodic adjustments. The MSC is controlled by software and input settings programmed by the user via the front LCD panel or via web browser software. 5 2 Air Filters The MSC contains two air filters located inside the front panel. The filters should be checked periodically for excessive dust build up. The filters are accessed by turning the unit off, disconnecting AC power and removing the top cover. The filters should be removed and cleaned with compressed air or water, dried and replaced before putting the unit back into operation. 5 3 Fuses The MSC has auto ranging AC input between nominal 120 and 240 Volts AC, 50/60 Hz. No AC input changes are necessary using either voltage. The AC supply jack is located on the rear panel adjacent to the on/off switch. The inputs are fused at 4A 250V with 5x20mm slow blow fuses. The two fuses (part no ) are located inside the AC jack and accessible by removing a plastic cover/holder WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

Use the up/down arrow buttons to select the desired timeout setting, then press the " " button to enter the new setting. Caution A TIMEOUT SETTING OF NONE IS NOT RECOMMENDED AS THIS WILL SHORTEN THE LIFE OF THE LCD. Copyright 2013, Harris Broadcast WARNING: Disconnect primary power prior to servicing

97 Multi-System Controller MSC Software Updates There are two different versions of MSC software. Software version shipped prior to February Version began shipping in February The screens shown in this manual reflect use of the software version. The Software Version screens can be found in Figure 3 29 on page 3 28 (Main/Alt), Figure 3 29 on page 3 28 (N+1), or in Figure 3 49 on page 3 56 f (DualTran). Caution IF YOU ARE CURRENTLY USING MSC SOFTWARE VERSION DO NOT UPDATE TO THE VERSION. UPDATING TO THE NEWER SOFTWARE REQUIRES MSC AND MSC SWITCHER PATCHES. DISCUSS THE UPDATE WITH HARRIS BROADCAST SERVICE BEFORE PROCEEDING. Refer to " MSC Software Update Screens" on page 3 23 for details on software management screens and MSC software updates. 5 6 Transmitter Service Individual transmitters can be maintained within the system by placing the MSC in manual mode to prevent any transmitter switching. Pressing the Disable button on the individual transmitter disables MSC remote control activity. This effectively removes a transmitter from the system for maintenance. Note Always refer to the transmitter s technical manual for instructions on transmitter testing or maintenance Transmitter and MSC Control Blocking MSC control of a particular transmitter is accomplished by pressing the transmitter s remote disable button, allowing the user to work on that transmitter as long as it is routed to the load or antenna. If routed to the load, the MSC should be placed in manual mode to prevent undesired switch from load to antenna if a higher priority transmitter faults off. Note When the MSC is in auto mode activating the remote Disable button on a transmitter blocks the MSC from controlling that transmitter but it does not prevent that transmitter from being switched to the antenna. Switching is an independent MSC function. Caution BEFORE PERFORMING ANY MAINTENANCE/TESTING OF A TRANSMITTER, PLACE THE MSC INTO THE MANUAL MODE. THIS IS NECESSARY TO PREVENT THE MSC FROM SWITCHING THE RESERVE TRANSMITTER INTO THE ANTENNA IN THE EVENT A MAIN TRANSMITTER SHOULD FAULT-OFF. When a transmitter is turned off while in the remote disabled mode and the MSC is placed back in auto mode, the MSC regains the ability to switch that transmitter to the antenna if a fault should occur in a different main transmitter. The MSC must remain in manual mode to prevent the switch of a powered off transmitter to an active state. When transmitter testing or maintenance is completed be sure to engage the transmitter s remote control enable button to return control of the transmitter back to the MSC. Place the MSC into auto mode to enable autoswitching should a fault occur in a main transmitter WARNING: Disconnect primary power prior to servicing. Copyright 2013, Harris Broadcast

105 Multi-System Controller Section-VIII MSC I/O Module 8 1 Introduction The MSC I/O Module is an FPGA based design with twenty digital inputs, twenty digital outputs, eight analog inputs, and eight analog outputs. The FPGA communicates via SPI (Serial Peripheral Interface bus) to the MSC IP Module or other Master controller. The module s digital inputs and outputs are optically isolated and are capable of sinking or sourcing current based configuration jumper settings. The analog inputs and outputs are also jumper configurable to 5V or 10V. The module has a memory mapped expansion connector that mimics it s control interface. 8 2 Power Figure 8-1 MSC I/O Module Front Panel The I/O Module is typically powered by an external AC/DC converter Harris Broadcast part no The converter requires VAC input and outputs 12VDC 5A to the MSC I/O module. 8 3 Digital Inputs The MSC I/O Module has twenty digital inputs. The inputs are optically isolated and feature source or sink capabilities. The source/sink selections are based on banks of inputs (1 4, 5 8, 9 12, 13 16, and 17 20). A source/ sink status per bank is fed back to the FPGA and can be read by the host controller. The input voltage is selectable between an isolated 5V supply or the customer supplied input for sink applications using JP14. The Inputs are referenced to BGND. The following diagram, Digital Input with Bank Configuration Jumper, shows an input with the bank configuration jumper.

106 8 2 Section-VIII MSC I/O Module The I/O configuration is done using a square four position header and two position jumpers. The four position header reference designators per bank are as follows in, Table 8 1: Input Configuration Header Designators. The jumper configurations per bank for the headers are found in Table 8 1 Input Configuration Header Designator.

107 Multi-System Controller Digital Outputs The I/O Module has 20 digital outputs. The outputs are optically isolated, short circuit protected, and feature source or sink capabilities. The source/sink selections are based on banks of inputs (1 4, 5 8, 9 12, 13 16, and 17 20). A source/sink status per bank is fed back to the FPGA and can be read by the host controller. The output pullup resistor voltage for sink outputs is selectable by JP2 between an isolated 5V supply or the customer supplied input voltage. For source applications the isolated supply can also be selected. However, the supply current maximums must be kept in mind. The Outputs are referenced to AGND. Figure 8 3 shows an output with the bank configuration header. Figure 8-3 Digital Output with Bank Configuration Header If sink mode is selected but customer supplied input voltage is not used a pull up voltage in the customer s equipment higher than the +V Output can cause current to go through the diode that is internal to the FET Q44 (for example). Therefore removal of R248 (for example) is recommended. Removing R277 or removing jumper JP13 (2 3 only) will further isolate the circuit. The I/O configuration is done using a square four position header and two position jumpers.

109 Multi-System Controller Analog Inputs The A/D converter for the analog inputs is an AD7888ARUZ (HPN ). The AD7888 is an 8 ch, 12 bit converter with SPI interface. To maintain 5 V or 10 V compatibility, the analog input is reduced to 41% of its original value. The voltage is then buffered and passed to the AD7888. To maintain full scale (12 bit) conversions, the analog reference is adjusted by changing the jumpers on the configuration header JP7. The configuration settings can be found in Table 8 7 and the analog input electrical characteristics can be found in Table 8 8.

123 Multi-System Controller Section-IX MSC Switch Module 9 1 Introduction The MSC switch module can be used for switch control in an N+1 system, a main alternate system sometimes referred to as a 1 +1 system, or in a DualTran system. The wiring of the system varies with transmitter type, RF coaxial transfer switch manufacturer, and system size. Consult system wiring diagrams for more details. The MSC switch module interfaces the MSC controller with peripheral hardware switches. The switch module also contains six RF detectors with SMA female inputs on the rear of the unit. Systems that have more than six main transmitters (e.g. 6+1 system) require another set of detectors which can be added above the initial six. The MSC switch module, MSC display panel (optional) and MSC controller are all connected to an Ethernet switch. Static IP addresses are set for the transmitter and each MSC unit. Refer to the system documentation for these addresses. Figure 9-1 MSC Switch Module Front Panel Note DualTran operation requires and additional Interlock PWA G to be installed in the MSC Switch Module. It is located directly above the RF Detector PWA. I/O connections are via a 37 pin d-sub connector. See Figure Power The MSC Switch Module is typically powered by an external AC/DC converter Harris Broadcast part no The converter requires Vdc input and outputs 12 V dc 5 A to the MSC Switch Module. The +12 V dc supply can be used as the RF transfer switch control voltage. If a voltage other than 12 V dc is required and additional external power supply will be required. Switch S2 on the MSC switch module PWA (printed wiring assembly or circuit board), shown in Figure 9 17 on page 9 10, selects which power supply is used. "Cust +V" selects the optional power supply voltage. "RF SW CTL + V" position uses the 12 V dc supply.
