1.0 General Details: QUASAR is a 96 x 96 mm, flush mounted,

single screen multiple parameter display digital panel meter for

measuring electrical parameters. The meter is designed with

DSP technology to combine measurements of bothinstantaneous and cumulative values in an electrical feeder.

The device is built with a custom made, backlit, LCD display

to provide high-resolution view of various parameters to the

viewer. The parameters are displayed over all screens which

can be scrolled up & down by front panel push buttons. The

feeder parameters like CT / PT ratings, baud rates, port

address, demand parameters etc. are set by additional pushbuttons (PBs) on the front panel.

2.0 Front Panel Details: Please see fig. 1. The front panel has one

LCD display, 4 PBs and a LED. The functions of the PBs are

explained in the sections 2.3, 2.7 and Appendix 4. The LED

flashes at a rate proportional to the kWh in the feeder.

2.1 Display Features: QUASAR comes with a custom made LCD

display. The power parameters are displayed through all

screens. Please refer Appendix 5& 6 for details of parameters

displayed in each screen. Please also refer to Table-1&2 for a

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, themeter has to be repacked in its original packing.


12/48

12

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 bestored 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 :

5.1Power 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 minsand then demand is computed.


13/48

13

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 algebraicallyadding 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 k steady and V

will be blinking, indicating unit is in kilo Volt.

Unit of current: 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

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 below-

Standard RS485 (half duplex)

Baud rate Selectable- 9600, 4800 bpsParity Selectable- None, odd or even

Start bit 1 Stop bit 1

1.2 Protocol:

The RS485 interface uses MODBUS Protocol inRTU mode.

Communicating with the meter involves sending commands to

the meter for reading and writing the particular register. Themeter 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.


18/48

18

The receiving device monitors the elapsed time between

receipt of characters i.e. inter byte delay. Ifinter 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. thetime taken to send the first byte out in response to the

command is max. 60ms.

ADDRESS FUNCTION DATA CHECK

8 BITS 8 BITS N * 8 BITS 16 BITS

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 slavesinterpret 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 forexception response). The following functions have been

implemented in the meter.


19/48

19

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. Explanation of various function:

The purpose of this section is to define the general format for

the specific command available to programmers. The form of

each query message (in RTU transmission mode) and an

explanation of the function the query message performs areprovided.

All numbers in Modbus format are entered in hexadecimal.

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 eachrequest.

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.

In this particular example the data obtained for 1st phase

voltage is0x00005DE6 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.
