Circuit diagram Function
signal name
Not/Aus Emergency stop for higher level shut-down of the power
source.
To use this function, jumper 1 must be unplugged on PCB
T320/1 in the welding machine.
Contact open  welding current switched off
Sollwert Absenkstrom Control voltage specification for secondary current,
0-10 V (0 V = I
IGRO Relais Current flows signal
I > 0
Contact closed = welding current flowing
(forms contact with signal D)
Prozeßspannung Uist Actual welding voltage, measured on pin S,
0-10 V (0 V = 0 V, 10 V = 100 V)
SYN_A E Synchronisation for master/slave operation
SYN_A C
Str./Stp. Start/stop welding current, same as torch trigger.
Only available in non-latched operating mode.
+15 V = Start, 0 V  Stop
+15V Power supply
+15 V, max. 75 mA
Sollwert Hauptstrom Control voltage specification for main current,
0-10 V (0 V = I
Sollwert Frequenz Nominal frequency value
0-10 V (0 V= 50 Hz, 10 V = 0.1 Hz)
Not/Aus Emergency stop for higher level shut-down of the power
source.
To use this function, jumper 1 must be unplugged on PCB
T320/1 in the welding machine.
Contact open  welding current switched off
