CLOSE BACKUP
OPEN BACKUP
These two inputs control the status of the BACKUP VALVE
outputs, opening and closing as required by the user.
When this input is set to open, the OPEN BACKUP VALVE
output is set. When set to closed, the CLOSE BACKUP
VALVE output is set. (If both inputs are set, the OPEN
BACKUP VALVE output is set.)
FAULT RESET Input
This input allows the control to remotely reset all faults.
STEPPER RESET Input
This input will reset all the steppers to Step 1 and the weld
count to 0.
TIP DRESS/ADVANCE Input
This input moves the stepper to the beginning of the second
step in the stepper profile.
PRESSURE SWITCH Input
If the weld schedule contains the function WAIT nnn CY FOR
PRESSURE SWITCH, and this input does not become active
in the number of cycles specified, the control generates a
PRESSURE SWITCH fault and continues with the schedule.
The control aborts the weld schedule and generates a
PRESSURE SWITCH fault if the weld initiate is removed
while the control is waiting in the function WAIT FOR
PRESSURE SWITCH.
ISOLATION CONTACTOR Input
This input to the weld processor shows the state of the
isolation contactor: Either open or closed. It is normally open.
