Failure details
Solution
Fault-EO
Overload stop
Due to an error caused by overload, the UPS shifts to bypass
operation when in commercial operation, and stops outputting
power when in backup operation. (Note 5)
Turn OFF all the Power switches on the UPS
and connected devices, reduce connected
devices, and turn ON the "Power" switches on
the UPS and remaining connected devices.
Fault-ES
Output short-circuit
The UPS stops due to a short-circuit on the connected device
side or due to significant connected capacity overload.
Check that the AC input of any of the connected
devices is not short-circuited and that
connections did not exceed the rated capacity.
Fault-E1
Output voltage overvoltage
Due to an error in the output voltage (overvoltage), the UPS
shifts to bypass operation when in commercial operation, and
stops outputting power when in backup operation. (Note 5)
Turn OFF all the Power switches on the UPS
and connected devices, and turn ON only the
Power switch on the UPS again.
If the displayed content does not change, the
UPS is faulty. Contact your dealer or OMRON
Electronic Equipment Customer Support Center.
Note: You can check the output voltage by
selecting "Measurement" menu - "Input and
Output".
You can check the battery voltage by
selecting "Measurement" menu - "Battery".
Fault-E2
Output voltage undervoltage
Due to an error in the output voltage (undervoltage), the UPS
shifts to bypass operation when in commercial operation, and
stops outputting power when in backup operation. (Note 5)
Fault-E3
Battery voltage overvoltage
Due to an error in the battery charging voltage (overvoltage),
the UPS shifts to bypass operation when in commercial
operation, and stops outputting power when in backup
operation. (Note 5)
Fault-E4
Battery voltage undervoltage
Due to an error in the battery charging voltage (undervoltage),
the UPS shifts to bypass operation when in commercial
operation, and stops outputting power when in backup
operation. (Note 5)
Fault-E6
Abnormal temperature
Due to an abnormal internal temperature, the UPS shifts to
bypass operation when in commercial operation, and stops
outputting power when in backup operation. (Note 5)
Check that the ambient temperature of the UPS
is 40 degrees Celsius or lower.
Fault-E8
FAN Fail
Due to an internal cooling fan abnormality, the UPS shifts to
bypass operation when in commercial operation, and stops
outputting power when in backup operation. (Note 5)
Check that the rotation of the fan is not
interfered with.
Fault-E11
Internal CPU communication error
Due to an error in communication between the CPU in the
battery pack and the CPU in the UPS, the UPS shifts to
bypass operation when in commercial operation, and stops
outputting power when in backup operation. (Note 5)
Check that the battery connector is not
disconnected.
Note 5: Commercial power is output as-is during bypass operation.
If the UPS cannot shift to bypass operation, or if a power outage occurs (AC input turned OFF) during
bypass operation, a maximum of 2 types of messages may be displayed on the LCD.
3-1-8 Message at bottom
According to the status of the UPS, a message is displayed at the bottom of the LCD.
Use it as reference information for operation.
3-1-9 Change the language
When the menu type is "Standard" and the language setting is changed from Japanese to
English, operate according to the following procedure.
1.
Connect the AC input cable to the outlet, and press the
switch.
