If this contact fails to change states after a valid schedule is
initiated, the control will generate a ISO-CNTR OFF WHEN
NEEDED fault condition.
If this contact fails to return to its original state after the
contactor is turned off (including the Isolation Contactor
Delay), the control will generate an ISO-CNTR ERR BKR
TRIPPED fault condition. It will also de-energize the NO
FAULT output and trip the circuit breaker.
ENABLE ISOLATION CONTACTOR Input
This input must be active (HIGH) to enable the weld
processor to activate (close) the isolation contactor.
ISOLATION CONTACTOR SAVER Input
This input tells the weld processor to enable the isolation
contactor delay timer. The delay timer (programmed in the
setup parameters, as described on page 6-12), holds the
isolation contactor closed after a weld schedule is completed,
to prevent it from dropping out between welds.
If this input is active at the end of a schedule, the weld
processor will hold the isolation contactor closed for the
amount of time programmed.
If this input is not active, the isolation contactor will drop out
at the end of the weld schedule. However, if this input drops
out during the delay time, the remaining time on the delay
timer is aborted and the isolation contactor is immediately
opened.

PROGRAM MODE SECURITY Input
If this input is active (locked HIGH), only data under the
Stepper Status Mode and Heat Display Mode can be
changed.
If this input is used in conjunction with the HT DISPLAY
SECURITY input, only data under the Stepper Display Mode
can be changed.
