Circuit diagram Function
signal name
PE Connection for cable screen
PULSEN EIN Thermal pulse mode up to max. 50 Hz, fixed balance of
50%
SYN_E Synchronisation for master/slave operation
IGRO RELAY Current flows signal
I > 0
Contact closed = welding current flowing
(forms contact with signal G)
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
INOMINAL LOW Control voltage specification for secondary current,
0-10 V (0 V = I
IGRO RELAY Current flows signal
I > 0
Contact closed = welding current flowing
(forms contact with signal D)
UACTUAL Actual welding voltage, measured on pin S,
0-10 V (0 V = 0 V, 10 V = 100 V)
SYN_AE Synchronisation for master/slave operation
SYN_AC
START/STOP Start/stop welding current, same as torch trigger.
Only available in non-latched operating mode.
+15 V = Start, 0 V = Stop
+15 V Power supply
+15 V, max. 75 mA
I HIGH Control voltage specification for main current,
soll
0-10 V (0 V = I
FREQUENZ Nominal frequency value
0-10 V (0 V= 50 Hz, 10 V = 0.1 Hz)
Emergency stop 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
0 V Reference potential
I Welding current, measured on pin S,
