IGRO
Current flows signal I>0 (maximum load 20
mA / 15 V)
0 V = welding current flows

Input
Not/Aus Emergency stop for higher level shut-down
of the power source.
To use this function, jumper 1 must be
unplugged on PCB M320/1 in the welding
machine. Contact open

G/P
Output
I>0
Power relay contact, galvanically isolated
(max. +/-15 V / 100 mA)
H
Output
Uist
Welding voltage, measured against pin F,
0-10 V (0 V = 0 V; 10 V = 100 V)

N
Output
-15 V
Voltage supply (max. 25 mA)
S
Output
0 V
Reference potential
T
Output
Iist
Welding current, measured on pin F;
0-10 V (0 V = 0 A, 10 V = 1000 A)

) The operating mode is given by the wire feed unit (the start / stop function equates to pressing
the torch trigger and is used in mechanised applications, for example).
