1. Introduction

The Current Transducer is a DIN Rail/wall mounted 43.5 X

65.5mm Transducer.

Input Current and Output Voltage / Current is displayed on LCD and indicated by LED’s.

The Current Transducer is used to measure and convert AC Current input into proportional DC current or voltage output signal. Output signal generated is proportional to the True RMS (upto 15th Harmonic) of the input Current.

Current Transducer can be configured and programmed at site for the following CT Primary ,CT Secondary (1A to 5A) , Input Characteristics (i.e start, end and elbow value of Input) and Output parameters (i.e as Voltage or as Current and Characteristics of start, end and elbow value of outputs).

3.2

For programming of transducer, steps to be followed are

Step 1 : DIP Switch setting

DIP Switches should configure for desired Output type as per given in section 3.3.1

Step 2 : programming

Programming Via Programming port available at front of Transducers using optional PRKAB60 Adapter

A PC with RS 232 C interface along with the programming cable PRKAB60 and the configuration software are required to program the transducer.

( Details of t he programming cable and the software are to be found in the separate Data sheet: PRKAB 60 Le.)

The connections between “PC PRKAB 60 Transducer. The power supply must be applied to before it can be programmed. The Configuration software is supplied on a CD. The programming cable PRKAB600 adjusts the signal level and provides the electrical insulation between the PC and Transducers.

3.3 Programming Via optional RS485 (MODBUS) communication port.

1) To change O/P switches from Current to Voltage or vice versa, ensure that transducer should be Electrically dead and all connection wires should be disconnected.

(Refer section 4 for programming through MODBUS)

3.3.1: DIP Switch Setting for Changing Output type

The Transducer output type can be changed from DC current to DC voltage depending upon user requirement on site. To change output type user has to set the transducer output type parameter either to voltage or current along with DIP switch setting. The transducer output type parameters can be configured using one of the three below given methods.

A) PRKAB 601(optional) : Using PRKAB601 through Transducer programming port (COM) and using PC based configuration software.

B) Front display (optional): Using front display user can enter into programming mode and can change the output type.

C) Modbus Rs485(optional): Using Modbus interface user can configure the output type refer Modbus Rs485 section.

Note: If DIP switch setting is done first and then output type parameter is configured using either of the above three methods then switch OFF - ON the Transducer. For changing DIP switches follow these steps

Switches of Output 2,can be set for desired Output type Voltage or Current.

Switches of Output 1,can be set for desired Output type Voltage or Current.

6) After inserting the front cover insert the Interface card PCB and back cover..

Insert the Interface card PCB and Back cover, press in direction of arrow.

7) After inserting the Back cover transducer, can be used for required application..

Insert the front cover, press in direction of arrow.

5) After changing the switches for desired Output, Insert the front cover.

4. RS 485 ( ModBus )

Current Transducer 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 length of 1.2km. Including the Master, a maximum of 32 instruments can be connected in RS485 network. The permissible address range for Current Transducer is between 1 and 247 for 32 instruments. Broadcast Mode (address 0) is not allowed.

The maximum latency time of current transducer 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 200 ms of time to elapse before assuming that the Current Transducer 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.

Exception Cases : An exception code will be generated when Current Transducer 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

4.1 Accessing 3 X register for reading measured values

Two consecutive 16 bit registers represent one parameter. Refer table 2 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.

Example

To read parameter , Current: Start address= 06(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.

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.

5.1 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 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 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.

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.

5.2 Case Dimensions

5.3 Wiring

Input connections are made directly to screw-type terminals

with indirect wire pressure. Choice of cable should meet local regulations. Terminal for Current inputs will accept up to 2x 2.5mm cables.

5.4 Auxiliary Supply

it may be powered from the signal source, provided the source remains within the limits of the chosen auxiliary voltage. A switch or circuit, may

² or 1x 4mm²

Transducer should ideally be powered from a dedicated supply, however

be used in close

proximity to the equipment &

5.5 Fusing

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