INSUFFICIENT LINE VOLTAGE: (FAULT) (ALERT)
This fault indicates that the weld initiate was removed or
time expired while the control waited for the programmed
line voltage (in Function #72 or #73).
EXTENDED WELD: (FAULT) (ALERT)
This fault is generated under one of two conditions, based on
which REWELD function appears in the weld schedule:
• If the schedule contains the function REWELD IF CURRENT
LESS THAN 00000 AMPS, this indicates that the control was
not able to provide the desired secondary current during the
weld, and performed an unsuccessful reweld.
• If the schedule contains the function REWELD IF LOW
CURRENT LIMIT FAULT, this indicates that the control
performed a reweld, and the desired current was provided
during the reweld.
ISO CNTR OFF WHEN NEEDED: (FAULT)
The isolation contactor was not pulled in when required by
the weld schedule. This parameter is NOT programmable.
This fault is generated when the control detects that the
isolation contactor is open when it is trying to execute a weld
function. (The contactor must be closed to provide weld
current.)
On detecting this condition, the control schedules in No Weld
and generates this fault condition. If the control is in No Weld
mode, it does not generate a fault.
CURRENT REGULATION LIMIT: (FAULT) (ALERT)
(NONE)
The secondary current provided to a weld is monitored each
cycle during an ACC weld function, to provide the desired
current to a weld. If necessary, the control adjusts the current
provided based on the current read during the previous
cycle.
This fault occurs if the control hits a firing limit while trying
to obtain the desired current, indicating that it could not
compensate for the current drop. It can also occur of the
amount of current programmed in the weld function causes
the control to fire below 20%I.
