SUMMARY:
This Instruction will eliminate a nuisance power source fault light when connecting a DuraDrive
4-30 or 4-48 wire feeder. The fault condition is caused by a transient voltage spike in the 12
volt control circuit when power is applied to the DuraDrive feeder. An additional 22 microfarad
capacitor is added to increase the time constant of the power up reset circuit which eliminates
the false triggering of the fault light.
OPERATIONAL IMPACT:
None
