Operation 17 Inverter Asynchronous This alarm is triggered by an in verter softwa re routine when the inverter and bypass waveforms are misaligned by more than 6 degrees in phase. This ala rm resets automatically once the condition is no longer true . 1. First check if the alarm “Bypass unable to trac e” or “Bypass abnormal” occurs. If so, [...]

Operation 18 Bypass Phase Reversed The phase sequence direction of bypass voltage is reversed. Normally, the phase of phase B lags 120 deg r ees behind phase A, and the phase of phase C lags 120 degrees b ehind phase B. Verify that the phase rotation of the bypass sup ply presented to the UPS is correct, and rectify it if it is found to be in error[...]
