+24 V high voltage release:
Input high voltage release via external 24 V signal.
The <Release Source> parameter must be set to <24 V signal>.
The parameter <Release Mode> must be set to <external> or
<in external>, with the release mode <internal>, the external
release signals are not taken into account.
The parameter <Ext. HV on> must be set for <YES>.
U = 24 V DC/24 V AC ±10 %, I < 20 mA
11
GND high voltage release:
Input high voltage release via external 24 V signal.
12
+24 V
This pin serves solely to supply a potential-free contact for the high
voltage release.
maximum current load: 50 mA.
13
GND for setpoint and actual values.
14
Voltage or current setpoint (input) depending on switch position S1/4:
Switch S1/4 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>.
15
Actual value U = 0...20 mA (output):
0 mA corresponding to 0 kV, 20 mA correspond to 30 kV output
voltage.
max. load: 500

16
Actual value I = 0...20 mA (output):
0 mA corresponding to 0 mA, 20 mA correspond to 5 mA output
current.
max. load: 500
