Fault Conditions 8
The fault conditions generated by the timer unit may not always identify
the source of the problem. However, they do provide a starting point to
begin searching.
Certain conditions are defined as Faults or Alerts in the setup
parameters. However, the control’s response to the conditions is
standard:
When the control detects a Fault condition, it may inhibit welding or
inhibit initiation of a new schedule until the fault condition is cleared.
Alert conditions serve more as a warning of a potential problem, or that
maintenance may be required.
NOTES:
The MFDC inverter provides fault detection, and generates additional
fault conditions. The inverter uploads fault conditions to the timer unit
after each weld sequence.
An inverter fault will activate the NO FAULT output at the timer unit,
and the READY TO WELD (RTW) output.
The following tables list each fault:
