Description
Circuit Breaker 1 hardware feedback fault
(Wiring Error Detection)
DC DS1 Disconnect hardware feedback fault
(Wiring Error Detection)
DC DS2 Disconnect hardware feedback fault
(Wiring Error Detection)
DC DS3 Disconnect hardware feedback fault
(Wiring Error Detection)
Occurs when a DC Disconnect is manually
opened during operation.
Local E-Stop pushbutton asserted
Filter Capacitor Fuse Fault
Indicates one of the filter-capacitor fuses
failed in Stack 1.
Filter Capacitor Fuse Fault
Indicates one of the filter-capacitor fuses
failed in Stack 2.
Resolution
Following these steps. if fault continues, contact Eaton service
1. Check CB1 wiring
2. Ensure that CB1 is powered
Check DC Disconnect DS1 wiring
Check DC Disconnect DS2 wiring
Check DC Disconnect DS3 wiring
1. Do not open DC disconnects (DS1 DS2 DS3) while running
2. Check DC disconnect shunt-trip wiring.
1. Pull OUT the E-Stop button
Button pulled OUT is the "normal" non-fault position
2. Reset fault via HMI
3. Check E-Stop wiring on the control section cabinet door
The three circuit contacts are of the N.C. (fail-safe) type
Check the 400 A LC filter fuses in Stack 1 (continuity check)
