2.8 RS485 COMMUNICATION (optional): With this option, the meters can be networked and various parameters can be monitored on a central PC. All parameters will be available via the RS 485 port. Set up configuration is also possible through this port. Protocol: MODBUS in RTU mode. Refer appendix 3 and appendix 2 for RS485 & MODBUS details. 3.0 Installation: 3.1 Incoming Inspection: Before the meter is installed, visual inspection for any damage due to transport, has to be done. If there are any damages, please refer the warranty sheet and take appropriate action. 3.2 Re-Packing: If the meter has to be returned to the supplier, the meter has to be repacked in its original packing.

11

3.3 Optimum Field conditions: For the reliability and better life of product, the unit has to be operated at moderate temperatures and humidity. The meter is designed to work from –5 to 60 degrees C and humidity of 95%RH non condensing. 3.4 Storage: In case of meter not installed after receipt, it has to be stored in a dry place in its original packing material. 3.5 Extra Precautions: Make sure that voltage, current ratings and the configuration of meter is as per the requirements. Wrong connection can severely damage the meter, which is not covered under warranty. 3.6 Wiring connections: Wiring of the meter has to be done as per wiring diagrams in appendix-7. 4 Mechanical dimensions; As per appendix-8. 4.1 Mounting on the panel: The meter is supplied with clip on type mounting accessories. After inserting the meter into the designated cut out on the panel, the clip on clamps have to be fixed on the back side to hold the meter against the panel firmly. 5.0 Specific Points: QUASAR uses CT/PT inputs for measuring and display of electrical parameters. Following points should be noted : 5.1 Power demand calculation: Integration period starts and continues from power on, i.e. if integration period selected is 30mins. and if 20mins of integration period is completed and power fails, then in the next power ON, the power is accumulated for the next 10 mins and then demand is computed.

12

5.2 Current reversal conditions: a) kWh energy is updated as it is with the sign i.e. negative energies are subtracted & positive energies are added and stored in a single register (no forward & reverse). The negative reading is made positive by adding 10^8. b) For kWh energy, demand is calculated by algebraically adding the powers, but if final demand is negative then display shows “0.0.0.0” just to indicate that something is wrong. c) When the meter connections are wrong, it will not show display parameters properly. 5.3 Unit of Voltage and current when kilo: Unit of voltage: for PT ratio <=30 unit is “V” for PT ratio > 30 unit is “k” steady and “V” will be blinking, indicating unit is in kilo Volt. Unit of current: for CT ratio <=75 unit is “A” for CT ratio >75 unit is “k” steady and “A” will be blinking, indicating unit is in kilo Amps. Note: i) For Voltage and current “k” will not be there in Total Power, Avg Voltage & current display (Default display no is 1) ii) Meter is not designed for export mode. 6.0 Programming the meter: Parameters like CT/PT ratios etc have to be programmed into the meter so that it can read the feeder data correctly. Please refer Appendix – 4 for details of how to programme the meter.

Appendix 2: MODBUS DETAILS 1.

Details of communication interface: RS485 interface is available to communicate with the meter. The interface is available at the terminals. For connection details refer Appendix 7.

1.1 Interface Standard: The configuration details to communicate with the meter are given belowStandard RS485 (half duplex) Baud rate Selectable- 9600, 4800 bps Parity Selectable- None, odd or even Start bit 1 Stop bit 1 1.2 Protocol: The RS485 interface uses MODBUS Protocol in RTU mode. Communicating with the meter involves sending commands to the meter for reading and writing the particular register. The meter can be addressed with specific user defined meter address (slave ID) from 1-255. 2 Details of MODBUS protocol: In the explanation of protocol the examples used are specific to L&T meters. The details of the protocol are also limited to L&T meters. 2.1 Remote Terminal unit Framing: In RTU mode data is sent as 8-bit binary characters. In RTU mode, message characters must be transmitted in a continuous mode.

17

The receiving device monitors the elapsed time between receipt of characters i.e. inter byte delay. If inter byte delay is three and one half the character time (for e.g. at 9600bps, the max. inter byte delay expected will be 1ms*3.5), the receiving device can timeout. The max. response time of the meter to a command, i.e. the time taken to send the first byte out in response to the command is max. 60ms. ADDRESS

2.2 Address field: The meter can be addressed with specific user defined address from 1-255. Each slave must be assigned a unique address and only the addressed slave responds to query that contains its address. When the slave sends a response the slave address informs the master which slave is communicating. In broadcast message, an address of 0(zero) is used. All slaves interpret this as an instruction to read and take action on the message, but do not issue a response message. 2.3 Function field: The function code field tells the addressed slave what function is to be performed. The higher order bit in this field is set by the slave device to indicate that other than a normal response is being transmitted to the master device (See Section 3 for exception response). The following functions have been implemented in the meter.

ACTION Obtains current binary value in one or more holding registers. Obtains current binary value in one or more Input registers. Place a specific binary value into a holding register.

Preset multiple registers

Places specific binary values into a series of consecutive holding registers.

2.4 Data Field: The data field contains the information needed by the slave to perform the specific function or it contains data collected by the slave in response to a query. 2.5 Error Check Field: This allows the master and slave device to check a message for error transmission. The error check field uses a CRC-16 check in the RTU mode. 3.

Exception responses: Exception response is a notification of an error. The exception response codes are listed in the table 3-1.When a slave detects one of these errors, it sends a response to the master consisting of slave address, function code, error code and error check field. To indicate that the response is a notification of an error, the high order bit of the function code is set to 1.

4.1 Read Output Register (Function Code 03) Query: Read output Register (03) allows the user to obtain the binary contents of holding register in the addressed slave. The addressing allows up to Max.90 registers to be obtained at each request. Broadcast mode is not allowed. The below example reads registers of 1st phase voltage from slave number 17(decimal). Since 1st phase voltage is stored in the address 0000 and 0001 so to read phase voltage both addresses should be read simultaneously. Example: Query Message SLAV E ADDR

In this particular example the data obtained for 1st phase voltage is 0x00005DE6 which if converted into integer will be 24038.So to get the voltage of the phase this particular value should be multiplied with the specified multiplication factor (MF) which is 0.01 in this case. (For further details see the memory map of the parameters). So 24038 x 0.01=240.38 which is the phase voltage. 4.2 Preset Single Register (Function Code 06): CAUTION: Function (06) will overwrite controller memory.

22

Function (06) allows the user to modify the contents of a holding register. The contents of only those holding registers can be modified which are write only. The values are provided in binary, up to the maximum capacity of the controller (16Bits in L&T meters) and unused higher bits must be set to zero. When used with slave address zero (Broadcast mode), all slave controllers will load the specified registers with the content specified. Example: This example will set the CT primary value in slave number 17.The address of CT primary is 2048 and value to be programmed is 1000. Query Message SLAV E ADDR
