List of secondary alarms
These alarm messages may be
consulted by pressing the "alarms" ("!")
button when the "!" character appears
at the end of a general alarm message.
The "alarms" ("!") button can then be
used to read the other alarms from the
list.
EMERGENCY SHUTDOWN
AUXILIARY COMMAND !
The remote emergency-shutdown
button has been pressed with as a
result:
◗ shutdown of the inverter;
◗ shutdown of the rectifier/charger;
◗ opening of battery circuit breaker
QF1;
◗ transfer of the load to Mains 2.
To ensure full powering down of the
system, this button must also open the
external upstream circuit breakers
supplying Mains 1 and 2.
LOAD ON
MAINS 2 !
The load has been transferred to
Mains 2 and is no longer protected.
MAINS 2 PROBLEM
CHECK FREQUENCY !
Mains 2 frequency is outside tolerances
and the inverter, unable to synchronize,
has switched to free-running frequency
mode. Transfer of the load from the
inverter to Mains 2 or vice-versa will
result in an interruption of the supply of
power to the load.
MAINS 2 PROBLEM
CHECK VOLTAGE !
Mains 2 voltage is outside tolerances.
Transfer of the load from the inverter to
Mains 2 or vice-versa will result in an
interruption of the supply of power to
the load.
FREQUENCY IMPOSED
DESYNCH. COMMAND !
The inverter has received an external
command to desynchronize its output
frequency with that of Mains 2.
an undersized engine generator set.
I BATTERY LIMITED
AUXILIARY COMMAND !
The rectifier/charger has received an
external command to limit the charge
current supplied to the battery. The
normal charge current will be supplied
when Mains 1 returns. This situation is
encountered, for example, when the
system operates on power supplied by
an undersized engine generator set.
Note:
The battery charge current limit value
may be programmed.
BATTERY BREAKER
QF1 OPEN !
QF1 battery circuit breaker has tripped
or is open. The load is no longer
protected because battery power in
unavailable in the event of a Mains 1
outage.
LOW BATTERY
... !
The inverter has shut down at the end
of battery power.
CHARGER OFF
... !
The rectifier/charger has shut down.
CHARGER FAULT
CALL SUPPORT DEPT.!
A fault has occurred in the rectifier/
charger module requiring servicing by
the after-sales support department.
MAINS 1 SWITCH
Q1 OPEN !
Mains 1 input switch Q1 is open. It
must be closed for rectifier/charger
start-up.
I INVERTER > IN
CHECK P.F. KW
An inverter overload has occurred due
to a load power factor greater than 0.9.
The blinking "kW" sign at the end of the
message is a prompt to read the load
power factor.
INVERTER IMPOSED
AUXILIARY COMMAND !
The inverter has received an auxiliary
command inhibiting transfer to Mains 2.
In the event of an inverter malfunction
and shutdown, the load will no longer
be supplied.
BATTERY OVERTEMP.
CHECK FANS !
This message is displayed only if the
"Temperature Monitor" option has been
installed. It signals that the battery
temperature is outside tolerances.
BATT. HOUSING VENT
OR HARM FILTER FAULT!
A fault requiring servicing has occurred
in the battery room ventilation system.
The rectifier-charger stops after
30 seconds.
If the installation includes a harmonics
filter, this light will also signal an
overtemperature of the filter’s inductor.
MAINS 1 PROBLEM
CHECK FREQUENCY !
Mains 1 frequency is outside tolerances
and the RC has shut down. The
inverter is on battery power.
MAINS 1 PROBLEM
CHECK VOLTAGE !
Mains 1 is down or its voltage is outside
tolerances and the rectifier/charger has
shut down. The inverter is on battery
power.
CHARGER SHUTDOWN
AUXILIARY COMMAND !
The rectifier/charger has received an
external command to progressively
shut down (for example, for a
progressive transfer to an engine
generator set).
INPUT KVA LIMITED
AUXILIARY COMMAND !
The rectifier/charger has received an
external command to limit the power
drawn on Mains 1. The remaining
power required for the load is supplied
by the battery. This situation is
encountered, for example, when the
system operates on power supplied by
"Monitor" alphanumeric display (cont.)
