7.3.7 Fault List
All UPS fault messages are described in Table 7-5.
Table 7-6 Fault list
The battery is bad or weak
The battery is bad or weak
The output connection is short-circuited
8 UPS Over-temperature
Over-temperature occurs to the UPS and the UPS will transfer to
Bypass mode
At least one fan is faulty
If a fault occurs, the UPS automatically switches to Bypass mode. Only in the case of a battery disconnection fault will
the original operating mode be maintained. The fault message alternates with UPS mode once a second, the red fault
indicator on the operation and display panel lights up and the alarm sounds continuously.
If a fault occurs, proceed as follows:
1. Enter the ALARM CONTROL screen (see Figure 7-18), and select ‘AUDIABLE ALARM ON’ or ‘AUDIBLE ALARM
OFF’ to switch on/off the alarm.
2. Enter the EVENT LOG screen (see Figure 7-21), and select ‘3 CRITICAL’ to view the fault log.
Note
Please wait patiently when you enter the EVENT LOG screen to view the historical fault log. Because the LCD display panel
needs to read the faults from the DSP at a relatively slow reading speed, the reading time depends on the uploaded information
quantity.
