Alarm Explanation
automatically resets once the overload condition is removed
System Overload
This alarm appears when the total load rises above 105% of the nominal rating of the
parallel system. The alarm automatically resets once the overload condition is removed
Out. Overload
Timeout The UPS overload status continues and the overload times out.
When the time has expired, the load automatically transfers to the bypass
Load Impact Transfer
A transfer to bypass occurred due to a large step load. The UPS can recover
automatically. Turn on the load equipment in stages to reduce the load impact on the
inverter
Excess Auto Rexfers
The load remains on bypass power owing to excessive number of transfers that occurred
within the one hour
Excess ECO Auto
Xfers The load remains on bypass power owing to excessive number of transfers that occurred
within the one hour
Load Sharing
Abnormal
The UPSs in a parallel system are not sharing the load current correctly
Other Module Xfer
All UPSs in the parallel system transfer to bypass at the same time when one of them
needs to transfer to bypass. This message appears on the TOUCHSCREEN of the UPS
with passive transfer to bypass
Control Power Fail The auxiliary power failure or power-off
EPO
EPO button on operator control and display panel pressed or external EPO command
received
Fan Abnormal At least one fan has fault
