Display - Pre-Charge Timeout
Description-
Pre-charge operation not completed within 30 seconds PV Voltage must be >0 Vdc close DS1 DS2 DS3PV-voltage relative to existing DC-Bus (stack)voltage must be <20 Vdc to perform pre-charge(close DS1-2-3).
Troubleshooting-
1. Verify PV voltage, allow DC-bus voltage to diminish(bleed-down). Reset fault on HMI, then re-start the pre-charge,closing disconnects within 30-seconds of the HMI “charging”state icon-buttons illumination.
