1. Description

3-way electrical isolation TRMS measurement Adjustable voltage ranges ZERO/SPAN adjustment 20%

MCR voltage transducers measure DC voltages in

several signal ranges 024 V DC to 0550 V DCand convert them into standardized analog signals. DCvoltages can be can be processed with both positiveand negative polarity.

The input voltage ranges of input terminals 1

7

can be adjusted by 20% using an adjustmentpotentiometer.

Upon delivery, the voltage transducer is set to024 V input and 010 V output and is ready foroperation. If you set the device to other input/outputvalues you must carry out a ZERO/SPAN adjustmentusing the potentiometer on the front plate.

2. Method of Operation

The input circuit divides the DC voltage at terminals1

7

. The resultant signal is transmitted electricallyisolated to the output circuit and is available as astandardized analog signal at the output.

3. Area of Application

When using the voltage transducer, ensure that thepotential difference between terminal1

7

andground potential PE, and terminal 8

and groundpotential PE does not exceed U = 660 V (prerequisite

for ungrounded circuits).In DC voltage networks, this potential differenceshould not exceed U = 100V (prerequisite forgrounded circuits).

If all of these conditions are met, safe isolation

isprovided between the input, output, and supply.

Caution: Never carry out work when thepower is turned on, this is highlydangerous.

If the voltage signal exceeds the voltagerange specified at the input signalterminal by more than 15% (with0...660 V by more than 5%), the inputcircuit may be damaged.

Every timethe input or output range is modified, aZERO/SPAN adjustment mustbe carried out.

6. ZERO/SPAN Adjustment

Upon delivery, the module is set to 0...24 V inputand 010 V output.

Two potentiometers are available on the front side ofthe module for adjustment (Fig. 08):

ZERO:

Zero point adjustment

SPAN:

Final value adjustment

d) Zero point adjustment

Connect a calibration source to the input terminals

(U

(1-7)

and GND1) and specify a voltage of 0 mV.

Set the output signal value using the ZERO

potentiometer.

Voltage output (010 V): U

OUT

= 0 VCurrent output (020 mA): I

OUT

= 0 mA

b) Final value adjustment

Use the calibration source to specify the maximumvoltage used in the framework of the input voltagerange (table 1).

Set the output signal value (U

OUT

= 10 V and I

OUT

=20 mA) using the SPAN

potentiometer.

Allow the module to warm up for 4minutes before starting the adjustment
