The Stop function is ensured by means of a floating contact which is to be con-
nected to terminals X4/3 and X4/4.
-
Opening the stop contact will interrupt:
-
the firing
-
the power supply to the parallel inputs and outputs
(only outputs for PSI 6101.321 / PST 6101.321)
-
the power supply to the external unit.

Configuration D:
Power supply for firing and parallel inputs and outputs
by an external 24 VDC power supply [1] (with PSI
6101.321 / PST 6101.321 only outputs).
Power supply to weld timer logics, the external device
and the serial inputs and outputs by a second external
