19 Design and Mode of Operation 2 Design and Mode of Operation The following chapter describes the mechanical and electrical design as well as the recorder components. 2.1 Summary The recorders are designed as panel mounted instruments with a format 144 mm x 144 mm. Installation without interspacing is possible in panels and mosaic systems with sufficient ventilation. The modern recorders have digital data processing. Measured values are recorded serially in channels and with solid state technology. As a result of the exclusive use of step motors, the drive system for recording operates completely without contacts. This technology permits a wide range of applications and high functional reliability. Fig and Fig show views of the recorder. The mode of operation of the recorders is explained down to the block chart level using Fig SIREC P, PA, L, LA Manual 2-1

22 Design and Mode of Operation 2.2 Recorder Components Housing The housing is made of sheet-steel. The chassis and the chart carriage are present at the front, the measuring module, the central processing unit, parts of the power supply and the options are located at the rear. The housing is mounted in the panel, mosaic system or desk upright panel using the supplied, standardized mounting elements Measured-value Acquisition Measured-value acquisition consists of a multiplexer with semiconductor relays and an analog-to-digital converter. The input ranges are set specifically for each channel using jumpers. The channels are electrically isolated from one another by staggered control of the semiconductor relays. Control is handled by the central processing unit. All channels to be measured during a cycle are connected to the input amplifier in succession via the individual semiconductor relays. The amplified signal is applied to an analogto-digital converter which operates according to the dual-slope procedure. In order to permit equally accurate measurements in sensitive ranges, reference measurements are carried out cyclically in the recorder version with universal measuring ranges. A cyclic check is also carried out for opencircuits. The terminal block also contains a sensor for measuring the terminal temperature when carrying out temperature measurements using thermocouples Central Processing Unit The central processing unit is the heart of the electronics. It contains a microprocessor as well as the program memory (EPROM), main memory (RAM) and non-volatile memory (EEPROM) for configuration data. Central component of the processing section is a microprocessor system with firmware. This is used, inter alia, for: T Sequence control T Calculation of measured values T Positioning of pen assemblies T Evaluation of input commands T Use of PC interface. The central processing unit permits control of the module "Digital input/output" and the PC interface. 2-4 SIREC P, PA, L, LA Manual

23 Design and Mode of Operation A crystal-controlled calendar/clock with external synchronization facility provides the date and time as a reference for sets of measured values and the chart. The central processing unit is located at the rear of the housing and is accessible from the front following removal of the chassis. It contains the plugs for connection of the other modules Power Supply AC 230 V or AC 115 V The recorders have different designs on the input side as a result of the four different power supplies which can be ordered. The mains power supply is connected to the recorder via an appliance plug with subsequent fuses, filter and transformer. The stepped down AC voltage is rectified, filtered and applied to DC/DC converters which generate the required internal DC voltages. Note The recorder must only be connected to the envisaged power supply. Observe the corresponding note on the rear of the recorder. DC 24 V The DC 24 V supply connected via the terminals is applied via a fuse to a power inverter whose output is connected to a transformer. The secondary side of the transformer is connected as in the recorder version with a mains power supply. AC 24 V The AC 24 V supply connected via the terminals is applied via a fuse to the primary side of the transformer. The secondary side is connected as in the recorder version with a mains power supply Chassis The chassis contains the chassis support, control PCB, recording system, user interface, PC interface and chart carriage. The chassis is connected to the central processing unit via a multi-conductor ribbon cable with plug. The cable length is such that the chassis can be completely removed from the housing without loosening the connection. Chassis support This is the support for the motors of the recording system, the control PCB, user interface and PC interface. The chart carriage latches into the chassis support and can be removed at any time using lever 2, e.g. to replace the chart. SIREC P, PA, L, LA Manual 2-5

24 Design and Mode of Operation Control "PCB" The control PCB contains the power electronics for the step motors of the drives as well as the light barrier for detection of the carriage zero points. It also contains a microswitch for recognizing the end of the chart paper, and several microswitches which are activated using the levers. Clock backup Only versions with alphanumeric text: the clock backup consists of a backup battery and capacitor. If a battery is not present, or if the chassis is separated from the central processing unit, the capacitor buffers the internal clock for approx. 5 minutes. The status of the clock buffer is checked when the power supply is switched on. The support for the backup battery is present on the control PCB and accessible following removal of the chassis. Recording system Chart carriage The recording system consists of up to seven step motors depending on the recorder version. These are used for: T Chart drive T Positioning of the pens (L/LA version) or the recording head (P/PA version) in the x-direction T Lifting of pens (L/LA version) or recording head (P/PA version) and T LA version: positioning of pen for text channel in x- and y-directions The chart carriage permits fanfold packs or rolls to be used as the chart paper. A take-up spool is required when using rolls (included in delivery). In addition, the chart carriage must be adapted when changing from fanfold paper to rolls. The required operations are described in Section 6 "Servicing and Maintenance". User interface The user interface consists of four levers and two LEDs underneath the chart carriage. A further lever is present on the side of the chassis and is only visible when the chassis is in maintenance position. Mechanical operations are directly activated by two of the four levers underneath the chart carriage. The other two levers can be used for two different actions each by moving the respective lever to the left or right. The TEST menu can activated and switched off again using the switch which is accessible on the side of the chassis. Green and red LEDs indicate different recorder statuses depending on how they are activated (on, off, flashing). PC interface The recorders are equipped with a PC interface. A laptop or PC can be connected via a special adapter cable. Convenient parameterization of the recorder is possible via the PC interface using a Windows desktop (SIPROM R). In addition, measured values, alarm statuses, date/time and chart feed A or B can also be scanned. 2-6 SIREC P, PA, L, LA Manual

26 Design and Mode of Operation 2.3 Mode of Operation As a result of the many different possible uses, the recorders are delivered preset to the basic setting of 4 to 20 ma. Customer-specific presetting is also possible as required. The recorder can then be used immediately following installation and commissioning. It is additionally possible to easily change the parameter settings of the recorder via the user or PC interface, thus permitting optimum and subsequent adaptation to the monitored process. The values measured cyclically by the recorder are amplified, digitized and processed further by a microprocessor system. In addition to processing of the measured values, the microprocessor system is responsible for sequence control, self-test, event processing, communication via the PC interface, control of the step motors of the recording system, feedbacks from the recording system and the user interface. The microprocessor system converts the measured value into positioning commands for the recording system. The recording system draw a continuous line on the chart paper. You can adjust the measuring and recording ranges such that the signal is recorded with an optimum resolution and display. It is also possible to define limits which are constantly recorded in the LA version as vertical lines. The recorders with alphanumeric text can output an alarm text if the limit is violated. The number of limits and the alarm function can be parameterized within wide ranges. If the recorder is equipped with the digital input/output option, the alarms can be output for further processing. Recorders with alphanumeric text can output a measured-value table, event text and recorder text cyclically or event-controlled. The texts must be entered previously via the user or PC interface when setting up the recorder. The outputs are made depending on the recorder parameters. 2-8 SIREC P, PA, L, LA Manual

If the recorder is equipped with a DC 24 V output (option), this voltage source can be used as an alternative, taking into account the technical data (Fig ). The recorder can synchronize the internal calendar/clock of several devices as slaves using a digital input/output. To achieve synchronization, any output of the digital input/output can be used on the master, and the input DI4 on the slave. Parameterization is described in Section SIREC P, PA, L, LA Manual 3-17

47 Preparation for Operation Fig Example of connection for digital input/output Explanations on Fig : The example shows two recorders with the digital input/output option. The digital input/output of the top recorder is powered by its own DC 24 V option output. The internal calendar/clock is synchronized for the two recorders. The required synchronization signal is provided via input DI4 by e.g. a master clock. The clocks of both recorders are set to 3:00 a.m. when the positive edge of the 24-V pulse arrives. The date remains unchanged. In addition to this, the digital output DO1 (alarm) of the top recorder triggers a lamp. SIREC P, PA, L, LA Manual 3-19

48 Preparation for Operation 3.8 DC 24 V Output Following installation of the option "DC 24 V output" by the manufacturer or by personnel trained by the manufacturer, a bipolar terminal (Fig ) is available at the rear of the recorder with a floating output for the supply of external components. The following connections are permissible since the current output is limited to max. 75 ma: T Up to three two-wire transmitters with a current consumption of 25 ma each T Digital input/output Note If several two-wire transmitters are powered, these must be connected together on one side and are thus not electrically isolated from one another. For noise reasons (differences in potential), this arrangement is only meaningful for transmitters which are close together. When additionally using the digital input/output, observe whether switching transients occur, and their effect.

51 Operation 4 Operation The following chapter describes how to operate the recorders. Note Replacing the chart and the battery for backing up the clock are described in Section 6. You are guided by menus when operating the recorders. The menus provide information in the form of a table on the respective functions or values for an input (leaflet "Parameterization a concise overview"). The input menus consist of several elements which are comprised in turn of menu code numbers and designations. In the first input step (selection of row) you decide which function or parameter is to be called. The red LED lights up. In the second step (selection of column) you can define or modify the corresponding setting of the recorder. The red LED flashes. The input of a menu code number is terminated by ENTER. You can scroll through the menu using the INC/DEC functions. 4.1 Display and Control Elements Operation is carried out using four horizontal levers located below the chart carriage (Fig ). A further lever is present on the side of the chassis. Two colored LEDs which are also located below the chart carriage serve to support you when setting up the recorders and for the output of status messages. In recorders with alphanumeric text, status messages are additionally printed on the chart paper by means of the text channel (LA version) or the recording head (PA version) (Section 5). The PC interface, which is designed as a flat plug, is located between the service lever and lever 1. It is possible to connect a laptop to this plug in order to carry out PC-controlled parameterization. SIREC P, PA, L, LA Manual 4-1
