Stud welding unit N1500i
As of: Aug 12.2021
Manual part number: BE 1221
10.3.3 E003 Capacitor Voltage Imbalance
Fatal, meaning you have to power down to continue welding
No
Acknowledge, meaning the error will exist as long as the unit is powered on.
(Note, welding can continue while the error exists)
.No
Description:
When (and only when) running the unit on the high range 400, the primary capacitor
bank has the potential to go out of balance such that they are not the same
voltage. When they are 20VDC out of balance for 10ms, the weld will be aborted to
protect the power unit. When opera- ting the unit with very low current and/or very
little cable load, unit will have the most opportunity for this imbalance. Use F18 and
the arrows to check left and right voltages.
Likely problems or items to check - in order from most likely to least likely:
Try reducing F2, which gives the most opportunity for delivering current through a
minimal load.
