MegaFlex 1000 to 1600 UPS User Manual / REV-A
Alarm Description
K3 OPENING FAILURE
K3 not open despite an opening command.
Be aware the DC Capacitors could remain charged.
NO INVERTER POWER
The Load supplied by Utility exceeds the Inverter power.
The Load remains supplied by Utility until the alarm stays ON.
FAN FAILURE
The Fan Control Board
indicates a malfunction of one or
more ventilators.
LOAD LOCKED ON UTILITY
Load is locked on Utility because 3 transfers on Utility have
been detected in a short time (default 30 sec.).
The transfer will be free after a time defined in parameter
(default 30 sec.).
LOAD ON UTILITY BY ERROR
DETECTOR
Load is transferred to Utility because the error detector
detected a disturbance on the output voltage.
EMERGENCY OFF ACTIVATED
Alarm after detection of an EPO (Emergency Power Off) from
an external safety device connected on Customer Interface
Board. Consequently K4, K6, K7 open, Rectifier, Inverter and
OVERLOAD
The UPS system is in an overload condition
Inverter, or >150% on Utility.
With Utility unavailable, a sequence of “stop operation”
starts. Time out depends on degree of overload.
OVERLOAD: LOAD ON UTILITY
With Utility Bypass supply available and Load
Load is transferred on Utility. Load
will be transferred again
automatically on Inverter when Load
<
INVERTER AND UTILITY
The voltages of Utility and Inverter
are not synchronized,
which causes the opening of K6.
ECO CONFIG FAILURE
The propagation of the eBoost™ configuration to other units
in an RPA Parallel System failed.
MAIN BOARD BATTERY CHANGE
NEEDED
Notice to replace the Lithium Battery located on the
DC CAPACITORS CHANGE NEEDED
Notice to replace the DC Capacitors.
AC CAPACITORS CHANGE NEEDED
Notice to replace the AC Capacitors.
Notice to replace the Fans.
SERVICE MAINTENANCE OVERDUE
Notice to do the Service Maintenance.
BATTERY OVERTEMPERATURE
Detection of Battery overtemperature condition.
Only an ABB Service Technician can reset the alarm.
BATTERY POWER INSUFFICIENT
In case of Utility Failure, with the actual Load, the run time
would be below stop operation time (default 3 minutes).
DC LOW
Battery voltage is at the lowest limit.
Inverter will remain Off until the Battery voltage
reaches the
value in parameter.
POWER SUPPLY BOARD FAILURE
Detection of a failure on the Power Supply Board
particular from the DC supply.
Can be enabled or disabled with respective parameter.
LOSS OF REDUNDANCY
A time of lost redundancy superior than specified in
respective parameter was detected.
LOAD LOCKED ON INVERTER
The Load is locked on Inverter after 3 Load transfers within
30 seconds.
After time out (default 30 sec.) Bypass will be free.
OVERTEMPERATURE
An overtemperature condition has been detected on Inverter.
Elapsed “stop operation” time, Inverter shut-down.
With Utility OK, Load is transferred on Utility.
LOAD OFF DUE TO EXTENDED
OVERLOAD
Load Off after time-out of “stop operation” for overload on
Inverter (time depending on the % of overload).
LOAD OFF DUE TO LOW BATT. OR
TEMP.
Load Off after time-out of “stop operation” with missing
Utility due to Battery
low voltage or overtemperature
condition.
