CURRENT MONITOR MODE:
(PRIMARY)
(
T03300 only
) (SECONDARY)
Select either
primary
or
secondary
current monitoring. If selecting
secondary current monitoring, a Secondary Current Interface Board
(SCIB) and secondary current-sensing coil must be attached. Refer
to Appendix G for a detailed description of the SCIB.
TRANSFORMER TYPE:
(AC WOUND)
(DC WOUND)
(AC STACKED)
(DC STACKED)
This parameter has four selections: AC WOUND, AC STACKED,
DC WOUND or DC STACKED.
When selecting
AC STACKED
or
DC STACKED
, the first half-
cycle of each pulse is fired completely, as required by the weld
schedule.
By selecting
AC WOUND
or
DC WOUND
, the control uses
delayed firing to prevent damage caused by firing at too great a
phase angle on the first cycle of a weld or impulse.
AC regulates on the current that is actually read. DC uses a special
algorithm to approximate the current.
CURRENT LIMIT MODE: (
T03300 Only
)(AVERAGE) (PEAK)
This parameter specifies which method the control will use during
current limit processing.
•
If this parameter is set to
PEAK
, the fault is generated if the
current limit is exceeded during any one cycle.
•
If set to
AVERAGE
, the control adds the current read during
each cycle and divides by the number of cycles to determine
average current. The fault is generated only if the average
current exceeds the limit.
INITIATION ON FAULT
(INHIBIT) (ALLOW)
This parameter tells the control how to react if it receives a weld
initiate when a fault condition is present.
•
INHIBIT
tells the control to ignore the initiate and generate
this fault.
•
ALLOW
tells the control to ignore the fault condition and
initiate the schedule.
