Designation
PE Connection for cable screen
REGaus For servicing purposes only
SYN_E Synchronisation for master/slave operation
IGRO Current flows signal I>0 (maximum load
20mA / 15V)
0V = welding current flowing
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
off
0V Reference potential
NC Not assigned
Uist Actual welding voltage, measured on pin F,
0-10V (0V = 0V, 10V = 100V)
Vschweiss Reserved for special purposes
SYN_A Synchronisation for master/slave operation
Str/Stp Start / stop welding current, same as torch
trigger.
