ISOLATION CONTACTOR Output
This output is activated or de-activated when the MedWeld
3005 executes function #52 (TURN ON ISOLATION
CONTACTOR) or function #53 (TURN OFF ISOLATION
CONTACTOR).
Function #77 (ISOLATION CONTACTOR DELAY nn SEC)
also affects this output, as described in the setup parameters
on page 6-12.
The output is used to remove power from the high-voltage
circuitry when it is not required by the weld schedule.
SHUNT TRIP Output
This output is provided to trip the circuit breaker in case of a
catastrophic failure.
WELD/NO WELD Output
When the WELD/NO WELD input is opened, it energizes
this output (to indicate that the control is in No Weld Mode).
If a valid weld initiate is received while the control is in No
Weld Mode, the weld schedule will schedule normally, but
weld current WILL NOT FLOW.
FAULT Output
This output is normally OFF, indicating that the control is
functioning normally. If the control shuts down as the result
of a fault condition, this output will be turned ON.
NO FAULT Output
Certain applications use the NO FAULT output (rather than
the FAULT output above). This output is normally ON (to
indicate that no fault conditions exist). If the control shuts
down as the result of a fault condition, this output will be
turned OFF.
NO ALERT Output
This output is normally ON. It turns OFF to indicate an alert
condition. Alert conditions are usually less serious than
faults and normally serve to warn the operator that
maintenance is required.
