3.8.2 Variant with connecting plugs
Pin assignment, analog interface
1 +24 V high voltage release:
Input high voltage release via external 24 V signal
U = 24 V DC ±10 %, I <20 mA
2 GND high voltage release:
The <Release Source> parameter must be set to <24 V signal>.
The parameter <Release Mode> must be set to <external> or
<internal + external>, with the release mode <internal>, the external
release signals are not taken into account.
Input high voltage release via external 24 V signal.
3/4 Voltage or current setpoint (input) depending on switch position S1/4
(pins 3 and 4 are internally bridged):
Switch S/4 ON: Setpoint 0...20 mA
20 mA corresponding to maximum output value (30 kV or 5 mA).
Load: 500
Switch S1/4 OFF: Setpoint 0...10 V
10 V corresponding to maximum output value (30 kV or 5 mA).
The parameter <Ext. setpoint> must be set for <ON>.
5 Actual value I = 0…20 mA (output):
0 mA corresponding to 0 mA, 20 mA correspond to 5 mA output
current.
max. load: 500
6 Actual value U = 0…20 mA (output):
0 mA corresponding to 0 kV, 20 mA correspond to 30 kV output current.
max. load: 500
7/8 Floating contact (fault alarm contact):
Output depending on parameter <Limit Signal>:
1. case: <Limit Signal = NO>: contact opens in the event of
malfunction (chap. 7).
2. case: <Limit Signal = YES>: contact opens in the event of
malfunction and when reaching the current or voltage limit.
max. 24 V / 0.5 A DC / AC
9 GND for setpoint and actual values.
