Manual maintenance breaker is opened
13
EPO
Emergency Power Off
14
Inv On Less
Available power module capacity is less then the load capacity. Please reduce the
load capacity or add extra power module to make sure that the UPS capacity is big
enough.
15
Generator Input
Generator is connected and a signal is sent to the UPS.
16
Utility Abnormal
Utility (Grid) is abnormal. Mains voltage or frequency exceeds the upper or lower limit
and results in rectifier shutdown. Check the input phase voltage of rectifier.
17
Byp Sequence Err
Bypass voltage Sequence is reverse. Check if input power cables are connected
correctly.
18
Byp Volt Abnormal
This alarm is triggered by an inverter software routine when the amplitude or
frequency of bypass voltage exceeds the limit. The alarm will automatically reset if
the bypass voltage becomes normal.
First check if relevant alarm exists, such as “bypass circuit breaker open”, “Byp
Sequence Err” and “Ip Neutral Lost”. If there is any relevant alarm, first clear this
alarm.
1. Then check and confirm if the bypass voltage and frequency displayed on the
LCD are within the setting range. Note that the rated voltage and frequency are
respectively specified by “Output Voltage” and “Output Frequency”.
2. If the displayed voltage is abnormal, measure the actual bypass voltage and
frequency. If the measurement is abnormal, check the external bypass power supply.
If the alarm occurs frequently, use the configuration software to increase the bypass
high limit set point according to the user’s suggestions
19
Byp Module Fail
Bypass Module Fails. This fault is locked until power off. Or bypass fans fail.
20
Byp Ov Load
Bypass current is over the limitation. If bypass current is under 135% of the rated
current. The UPS alarms but has no action.
21
Byp Ov Load Tout
The bypass overload status continues and the overload times out.
