This parameter is permanently set to the FAULT condition.
You CANNOT program it.
The following two parameters (along with Sec. Curr Coil
Multiplier (x1000)) support operation of the Secondary Current
Interface Board (SCIB):
SECONDARY CURRENT COIL/BOARD: (FAULT)
This fault will occur under the following conditions:
• If an error occurred while attempting to initialize or configure
the SCIB due to a malfunction on the SCIB board or an
improper connection to the weld timer.
• If an error occurred during the secondary current calibration
process due to an improper connection to the secondary current
coil.
• If an error occurred during the secondary calibration process
due to a loss of primary power (no zero-crossing
synchronization).
• If an error occurred during the secondary calibration process
due to a missing current range jumper on the SCIB board.
CURRENT MONITOR MODE: (PRIMARY)
(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.
