Function
A
Output
PE
Connection for cable screen
B
Input
PULSING ON
Thermal pulse mode up to max. 50 Hz, fixed balance of
50%
C
Output
Sticking
Analysis signal to detect sticking of the filler wire to the
workpiece 24 V = sticking
D
Output
IGRO RELAY
Current flows signal
I > 0
Contact closed = welding current flowing
(forms contact with signal G)
E
Input
EMERGENCY STOP Emergency stop for higher level shutdown 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
F
Input
INOMINAL LOW
Pilot voltage default for secondary current,
0–10 V (0 V = I
min
/10 V = I
max
)
G
Output
IGRO RELAY
Current flows signal
I > 0
Contact closed = current flows
(forms contact with signal D)
H
Output UACTUAL
Welding
voltage, measured on pin S,
0–10 V (0 V = 0 V, 10 V = 100 V)
J
Input
+24 V1
24 V voltage reference. Supplied by BUSINT X11.
K
Output
Phase OK
Signal to detect a failed network phase. Analysed by
BUSINT X11.
L
Input
START/STOP
Start/stop of welding current, corresponds to torch trigger.
Only available for non-latched operating mode.
+15 V = start, 0 V
=
stop
M

value
P
NC
R
Input
EMERGENCY STOP Emergency stop for higher level shutdown 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
S

V
Reference
potential
T
Output I
actual
Welding current, measured on pin S;
0–10 V (0 V = 0 A, 10 V = 1000 A)
U
Input
BR. KOLL: 1
Emergency shutdown for anticollision 24 V
V
Output
BR. KOLL. 2
Emergency shutdown for anticollision device
