Pin Signal Function
1 STARTA
Channel A Start.
Active at +24V.
The control device activates the EVSA output (Gun A call)
and executes the welding program demanded.
If Start is interrupted before the pressure cycles have
elapsed, the EVSA output is deactivated and electrodes open.
When pressure cycles are got over, the Start signal stays in
the self-holding mode up to the end of the frequency cycles.
2 STARTB
Same as STARTA but for channel B.
3 CEVASA
Control to solenoid valve for additional opening A.
Active at +24V.
Start of electrodes pre-approach; it is enabled and disabled
with 0 to 24V ramp up, (pulse type).
Signal reading time < 100mS.
If not used, this input is to be connected directly to +24V.
4 CEVASB
Same as CEVASA but for channel B.
