1. Introduction

This instrument is a panel mounted 96 x 96mm DIN Quadratic Digital metering system for the measurement of important electrical parameters like AC voltage, AC Current, Frequency, Power, Energy (Active / Reactive / Apparent). The instrument integrates accurate measurement of technology (All Voltage & Current measurement are True RMS up to 15th Harmonic) with 320x240 Pixels touch screen TFT LCD display.

This instrument can be configured and programmed at site for the following:

2. Measurement Reading Screens

In normal operation the user is presented with one of the measurement reading screens out of several screens. These screens form particular submenu may be scrolled through one at a time in incremental order by touching the “ key ” and in decremental order by touching “ key ” on that screen. Viewing of any individual parameter with large reading (eg. shown of Line to neutral Voltage L2 in sub meau 2 screen 13) is also possible by touching that particular parameter.

11. RS 485 ( ModBus ) Output :

This instrument supports MODBUS (RS485) RTU protocol ( 2-wire ).

Connection should be made using twisted pair shielded cable. All "A" and "B" connections are daisy chained together. The screens should also be connected to the “Gnd” terminal. To avoid the possibility of loop currents, an Earth connection should be made at one point on the network. Loop (ring) topology does not require any termination load. Line topology may or may not require terminating loads depending on the type and length of cable used. The impedance of the termination load should match the impedance of the cable and be at both ends of the line. The cable should be terminated at each end with a 120 ohm (1/4 Watt min.) resistor.

RS 485 network supports maximum lenght of 1.2km. Including the Master, a maximum of 32 instruments can be connected in RS 485 network. The permissible address range for the instrument is between 1 and 247 for 32 instruments. Broadcast Mode (address 0) is not allowed.

The maximum latency time for the instrument is 200ms i.e. this is the amount of time that can pass before the first response character is output.

After sending any query through software ( of the Master) , it must allow 200ms of time to elapse before assuming that the instrument is not going to respond. If slave does not respond within 200 ms, Master can ignore the previous query and can issue fresh query to the slave.

33

The each byte in RTU mode has following format:

8-bit binary, hexadecimal 0-9, A-F 2 hexadecimal characters contained in each 8-bit field of the message

Format of Data Bytes

4 bytes (32 bits) per parameter.

Floating point format ( to IEEE 754 ) Most significant byte first (Alternative least significant first)

Error Checking Bytes

Byte format

Communication Baud Rate is user selectable from the front panel between 2400, 4800, 9600, 19200 bps.

2 byte Cyclical Redundancy Check (CRC) 1 start bit,

Exception Cases : An exception code will be generated when the instrument receives

ModBus query with valid parity & error check but which contains some other error ( e.g. Attempt to set floating point variable to an invalid value ) The response generated will be “Function code” Ored with HEX (80H ). The exception codes are listed below

Accessing 3 X register for reading measured values:

Two consecutive 16 bit registers represent one parameter. Refer table 4 for the addresses of 3X registers (Parameters measured by the instruments). Each parameter is held in the 3X registers. Modbus Code 04 is used to access all parameters.

Illegal Data Address

Illegal Data Value

Attempt to access an invalid address or an attempt to read or write part of a floating point value

Attempt to set a floating point variable to an invalid value

Example :

To read parameter , Volts 3 : Start address= 04 (Hex) Number of registers = 02

Note : Number of registers = Number of parameters x 2

Each Query for reading the data must be restricted to 20 parameters or less. Exceeding the 20 parameter limit will cause a ModBus exception code to be returned.

This instrument contains the 20 user assignable registers in the address range of 0x200 (30513) to 0x226 (30551) (see Table 9). Any of the parameter addresses ( 3X register addresses Table 4)) accessible in the instrument can be mapped to these 20 user assignable registers. Parameters (3X registers addresses ) that resides in different locations may be accessed by the single request by re-mapping them to adjacent address in the user assignable registers area. The actual address of the parameters ( 3X registers addresses) which are to be assessed via address 0x200 to 0x226 are specified in 4x Register 0x200 to 0x213 (see Table 10).

To get the data throught User assignable Register use following step:

1)

Assign starting addresses(Table3) of parameters of interest to a “User assignable mapping registers” in a sequence in which they are to be accessed (see section “Assigning parameter to user assignable registers”)

2) Once the parameters are mapped data can be acquired by using “User assignable data register “ Starting address . i.e to access data of Voltage2, Power factor1,Wh import, Frequency send query with starting address 0x200 with number of register 8 or individually parameters can be accessed for example if current1 to be accessed use starting address 0x212. (See section Reading Parameter data through User Assignable Registers)

13. Installation

PANEL

SLIDE IN THIS DIRECTION AND LOCK

Mounting is by four side clamps, slide the side clamps through side slot till side clamp gets firmly locked in a groove (Refer fig.) Consideration should be given to the space required behind the

Meter

instrument to allow for bends in the connection cables.

57

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 panel 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

-20 to 70ºC. 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 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 internal fuses therefore external fuses must be used to ensure safety under fault conditions.

13.1 EMC Installation Requirements

This product has been designed to meet the certification of the EU directives when installed to a good code of practice for EMC in industrial environments, e,g,

1. Screened output and low signal input leads or have provision for fitting RF suppression components, such as ferrite absorbers, line filters ect., in the event that RF fields cause problems.

Note: it is good practice to install sensitive electronic instruments that are performing critical functions, in EMC enclosures that protect against electrical interference which could cause a disturbance in function.

2. Avoid routing leads alongside cables and products that are, or could be, a source of interference.

58

3. To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good EMC 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 of greater than 5 seconds to restore correct operation.

The Current inputs of these products are designed for connection in to systems via Current Transformers only, where one side is grounded.

4. ESD precautions must be taken at all times when handling this product.

13.3 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 up to 3mm2 x 2 diameter cables.

Note : It is recommended to use wire with lug for connection with meter.

13.4 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.

13.5 Fusing

It is recommended that all voltage lines are fitted with 1 amp HRC fuses.

13.6 Earth/Ground Connections

For safety reasons, CT secondary connections should be grounded in accordance with local regulations.
