6 1. Introduction The ultifunction DC Energy eter is a panel mounted 96 x 96mm DIN Quadratic Digital Panel eter,which measures important electrical parameters in DC Network and replaces the multiple analog panel meters. It measures electrical parameters like DC voltage, Current, Power, Energy(Import & Export), Demand & many more. The meter can be used for upto 4 channels. It integrates accurate measurement technology with bright LED display (8 digit x 4). The meter can be configured on site for various parameters including Nominal Voltage, Current Full scale Setting, Current Shunt Settings, No. of channels, Demand Integration Time etc. The front panel has three push buttons using which the user can scroll through different screens & configure the product. It also includes 20 LEDs which in conjunction with LED display, provides information in different units and gives overview of channel status. 8 digit x 4 seven segment LED display E DC Ch1 Ch2 (Bicolor) Channel LEDs (Green & Red) Ch3 Ch4 Old Imp Exp Dmd W A Rn hr Parameter LEDs Down key UP key 4 Enter key ultiplier LEDs

7 The channel LEDs serve many purposes. In setup menus, if a channel parameter is being displayed one of them glows green according to the displayed channel parameter. In measurement screens, they change color according to channel status i.e. healthy, alarm and overload conditions. Overload condition is defined as measured value > 126% of nominal value. Refer following points to decode the information that the LED provides. These points are true for measured parameters i.e. voltage and current. The LED glows green in healthy condition and becomes red in overload condition. If a limit relay is assigned to the channel, the LED will glow red if alarm condition is true and will glow green if healthy condition is observed. For derived parameters (power, energy, ampere-hour and demands), following points are applicable. When the voltage and current both are healthy, the LED will glow green. If one of the parameters(voltage or current) is in overload condition, LEDs for all the derived parameter calculated from that value will also turn red. If a limit is assigned to the parameter, the LED will glow red in alarm condition and green in healthy condition. When more than one from the above conditions are applicable, the LEDs will follow "OR" logic for alarm condition and "AND" logic for healthy condition, i.e. it will glow red when even one of the alarm conditions is true and it will only glow green when all of the healthy conditions are true. 6 There are two multiplier LEDs for each channel marked (kilo 10³) and (mega 10 ). Each will glow read according to the scaling required to the value on display. One or more from the parameter LEDs will glow red according to the parameter displayed on the screen. 2. easurement Reading Screens In normal operation, the meter shows one of the measurement reading screens out of several screens. These screens may be scrolled through one at a time in incremental order by pressing the UP key or in decremental order by pressing the DOWN key. 5

The values read as, Channel 1: 10 A Channel 2: A(20 x 10³) Channel 3: 300 A Channel 4: Overload condition An example of the power screen is shown in the picture. The values read as, Channel 1: 10 W 6 Channel 2: W(20 x 10 ) Channel 3: W(300 x 10³) Channel 4: Overload condition The channel LED for channel 1 and 2 is glowing green which means they are in healthy condition. The channel LED for channel 1 and 2 is glowing green which means they are in healthy condition. The channel 3 LED is glowing red and a measured value is being displayed, which means that there is a limit relay set on this channel and alarm condition is present. The channel 3 LED is glowing red and a measured value is being displayed, which means one from the following conditions is present 1) There is a limit relay set on this channel and alarm condition is present. 2) Any one from voltage or channel 3 current is in overload condition. The channel 4 LED is red with -OL- displayed on screen which means that the measured current on this channel is above 126% of nominal value set. 6

The display of the meter can only accommodate 8 digits. So to display more than 8 digit energy, an overflow screen is added. When the energy reaches the energy digit reset count, it starts the count from 0 again. When this happens the corresponding overflow is increased by 1. The maximum value of the overflow is 2000 for individual channels. Thus the highest energy that the meter can show is wh. To obtain the value for current energy reading, the user need to multiply the overflow count by 10 raised to energy digit reset count for the corresponding channel and add the result in displayed energy reading. Example: In the screens shown above, assume that the energy digit reset count for the channels are 8,7,6 and 8 respectively. So the energy reading for each channel will be as following: 8 Channel 1: [(100 x 10 ) ] = Wh 7 Channel 2: [(28 x 10 ) ] = Wh 6 Channel 3: [(8 x 10 ) ] = kwh 8 Channel 4: [(24 x 10 ) ] = wh The overflow value will start counting from 0 after reaching For total parameters with overflow this limit is Note: - DC E measures positive & negative Voltage, Current and it's derived parameters. 7

18 3. Installation ouinting is by four side clamps. Slide the side clamps through side slot till side clamp gets firmly locked in a groove (refer figure). Consideration should be given to the space required behind the instrument to allow for bends in the connection cables. As the front of the enclosure conforms to IP54, it is protected from water spray from all directions. Additional protection to the panel may be obtained by the use of an optional gasket. The terminals at the rear of the product should be protected from liquids. The instrument should be mounted in a reasonably stable ambient temperature and where the operating temperature is within the range -10 to 55 C. Vibration should be kept to a minimum and the product should not be mounted where it will be subjected to excessive direct sunlight. Caution 1. In the interest of safety and functionality of this product must be installed by a qualified engineer, abiding by any local regulations. 2. Voltages dangerous to human life are present at some of the terminal connections of this unit. Ensure that all supplies are de-energised before attempting any connection or disconnection. 3. These products do not have fuses, therefore external fuses must be used to ensure safety under fault conditions. 16

19 3.1 EC Installation Requirements This product has been designed to meet the certification of the EU directives when installed to a good code of practice for EC in industrial environments, e.g 1. Screened output and low signal inputs leads or have provision for fitting RF supression components, such as ferrite absorbers, line filters etc. in the event that RF fields cause problems. Note: It is good practice to install sensitive electronic instruments that are performing critical functions, in EC enclosures that protect against electrical interference which cold cause a disturbance in function. 2. Avoid routing leads alongside cables and products that are or could be a source of interference. 3. To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good practice to suppress differential surges to 2kV at the source. The unit has been designed to automatically recover in the event of a high level of transients. In extreme circumstances it may be necessary to temporarily disconnect the auxiliary supply for a period greater than 5 second to restore correct operation. 4. ESD precautions must be taken at all times when handling this product. 3.2 Case Dimentions and Panel Cut-out 17

20 3.3 Wiring Input connections are made directly to screw-type terminals with indirect wire pressure. Numbering is clearly marked in the plastic moulding. Choice of cable should meet local regulations. Terminal for both current and voltage inputs will accept upto 3mm² x 2 diameter cables. Note: It is recommended to use wire with lug for connection with meter. 3.4 Auxiliary Supply The instrument should ideally be powered from a dedicated supply, however it may be powered from the signal source, provided the source remains within the limits of the chosen auxiliary voltage. 3.5 Fusing It is recommended that the voltage line is fitted with 1A HRC fuses. 3.6 Earth/Ground Connections For safety reasons, ensure proper grounding of the panel in accordance with local regulations. 18
