Alarm Possible Cause Action
OUT OVLD alarm is present
Rms current drawn from any of the
output lines exceeds its nominal
value
Check if there is an overload and remove the
excessive load. If the total power drawn by the
load is less than the nominal power, make sure
that it is distributed evenly between phases.
INV BLKD alarm is present
Inverter operation is automatically
stopped due to a fault
Consult the technical service
VSEC NOK alarm is present
(Output voltage is beyond its
limits)
The UPS may not started up yet.
This alarm is permanent if the UPS
is intended to be started with the
bypass blocked or when the bypass
mains is not in specified limits
Check if there are any other alarms and apply the
related suggestions
Examine the preferences, check the mains
voltages and read the "modes of operation"
section of the manual.
If input voltage is between the limits check the
battery is OK.
The UPS may have stopped to feed
the load because the combination
of the mains conditions ant the user
preferences made from the
COMMANDS menu does not allow
the UPS to work in any of the
operation modes.(e.g. if inverter is
disabled and both input and bypass
mains voltages are not acceptable
or if the rectifier is disabled when
the bypass voltage is not in specified
limits or batteries may be
discharged during a prolonged
outage)
VIN HIGH alarm is present
Input line/neutral voltage is higher
than its upper limit
Check if the bypass mains voltage is in specified
limits
VIN LOW alarm is present
Input line/neutral voltage is lower
than its lower limit
IN SYN FLR alarm is present
Frequency of mains voltage is
beyond the frequency range for
normal operation or mains voltage
is very low
Check if the mains voltage is in specified limits
IN SEQ FLR alarm is present
Phase sequence of input mains
voltages is not OK Phase sequence of the mains input shall be
changed. Consult technical service
RECT OVTE alarm is present
Rectifier block temperature is very
high
Measure the ambient temperature near UPS.
Make sure that the temperature is in specified
limits.
Check if the fans are running.
RECT OVLD alarm is present
RMS current drawn from any of the
input lines exceeds its nominal
value
Check if there is an overload and remove the
excessive load.
VDC HIGH alarm is present
Any of the DC bus voltages is higher
than its upper limit
Consult the technical service
VDC LOW alarm is present
Any of the DC bus voltages is lower
than its lower limit
Means that the batteries had
discharged. It is removed when the
rectifier resets.
If you encounter this alarm during start-up, check
if the inrush circuit breaker is "ON"/"I".
Charge the batteries, perform battery test and
check if the alarm has removed.
RECT BLKD alarm is present
Rectifier operation is automatically
stopped due to a fault
Consult the technical service
