Output Not Sync
Asynchronous operation
Power supply is asynchronous with input power source.
Switching to bypass operation is instant cutoff switching.
Input Freq Err
Input frequency error
The input power source exceeds the acceptable frequency range. If it
occurs during normal operation, power supply automatically switches
to battery. If this problem occurs frequently, check the input power
source and the UPS frequency setting.
Input Vol Hi
High input voltage
The input power source exceeds the acceptable voltage range. If it
occurs during normal operation, power supply automatically switches
to battery. If this problem occurs frequently, check the input power
source and the UPS frequency setting.
Input Vol Low
Low input voltage
Input Error
Input error
Instant disconnection of input power source is detected. If it occurs
during normal operation, power supply automatically switches to
battery. If this problem occurs frequently, check the input power source
and the UPS frequency setting.
INV Vol Hi
High inverter voltage
(serious malfunction)
Inverter output voltage error is detected.
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
INV Vol Low
Low inverter voltage
(serious malfunction)
INV Vol Error
Inverter voltage detection
circuit error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
Output Stop (HV)
Bypass output stopped
(excessive voltage)
Power supply stops because input over voltage is detected during
bypass operation.
OverLoad
Overload
There are a lot of load devices connected to the UPS to exceed the UPS
rated capacity. Reduce the number of load devices.

Byp Fuse Error
Bypass fuse error
There are a lot of load devices connected to the UPS to exceed the UPS
rated capacity. As a result, the
MAIN MCCB
trips.
Reduce the number of load devices.
Bypass SW ON
Bypass switch ON
The forced bypass switch
Forced Bypass
is set to “Bypass”.
Req To Restart
Restart is necessary.
Values for settings are changed but they require restart of the UPS
before their changes take effect. Therefore, see §3.23 “Restarting UPS”
and then restart the UPS.
Remote
Battery test by remote
operation in progress
Battery test is in progress by remote operation of power management
software.
Remote OFF
Operation stops due to
remote OFF.
Inverter startup operation is canceled because remote OFF signal is
input.
EPO ON
Operation stopping due to
EPO.
Inverter startup operation is canceled because EPO signal is input.
Batt Life End
End of battery life
The battery life has come to an end. Replace the battery.
Batt Life Warn
Battery life end warning
The battery will last for 6 more months. Prepare to replace the battery.
Batt Vol Error
Battery voltage error
No battery pack is connected. Make sure a battery pack is installed.
Batt Vol End
End of battery discharge
Battery discharge has ended.
Batt Vol Low
Low battery voltage
Battery voltage is low.
CHG Error
Charger error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
CONV Error
Converter error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
FIN Temp Error
Fin temperature error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
DSP Error
Controller error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
BUS Error
DC voltage error
(serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
AUX2 Error
Auxiliary power error
(minor malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
BF Circuit Error
Back feed prevention circuit
error (serious malfunction)
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
Total Unit# Err
Total number of units error
(serious malfunction)
The number of UPS units set in §3.19 is different from the actual
number of UPS units operating.
Check the setting and the actual number of UPS units.
LCD Error
LCD panel error
The LCD panel is malfunctioning. Contact your supplier or SANYO
DENKI.
Minor Error
Minor malfunction
Contact your supplier or SANYO DENKI.
Fatal Error
Serious malfunction
UPS is malfunctioning. Contact your supplier or SANYO DENKI.
FT Disabled
Redundant operation not
allowed
In §3.20, if the operation system is set to “N+1”: there is a lot of load
capacity connected to the UPS so that parallel redundant operation is
not possible. Reduce the number of connected load devices.
Check Unit Error
Device error exists and
checking is required.
There may be communication error between units.
Check the cable connecting the units.
* Refer to §8 “Notes on UPS Measurements Information.”
