36.0.2 Battery & Battery Charger alarms
BATTERY CHARGER 1
ALARM (FAILURE)
These alarms are sent to Be126 via MOD-BUS from the battery chargers. It is about a
general failure of the battery charger. These alarms energize also when you connect the
alarm inputs JF-1 or JF-2 to the common battery minus. These inputs are used in case
your battery chargers do not support a MOD-BUS communication, but they feature a dry
contact alarm output relay. In case of alarm, check the fuses fitted on the battery
chargers.
BATTERY CHARGER 2
ALARM (FAILURE)
LOW BATTERY 1
WARNING
These are general purpose adjustable
alarms about ‘Battery 1’ & ‘Battery 2’. You can set
a ‘low limit’ and a ‘high limit’ for the batteries. An alarm bypass of about 15 seconds is
automatically provided
(see ‘Engine Parameter’ section 13.0).
HIGH BATTERY 1
WARNING
LOW BATTERY 2
WARNING
HIGH BATTERY 2
WARNING
36.0.3 Emergency Input
EMERGENCY INPUT
SHUTDOWN
This alarm triggers when you connect to battery minus the terminal JF-8. This alarms
shuts down the engine immediately. This input shall not be used in an a NFPA 20 or
EN12845 compliant system.
36.0.4 Miscellaneous engine alarms
PICK UP
FAILURE
This alarm triggers when the speed is lower than CRANK-RPM (rotational speed crank
termination) setting. The Be126 provides a 20 second alarm bypass. You are required to
correctly set-up the speed parameters in the
[ROTATIONAL SPEED]
settings (section 14.0).
OVER SPEED
SHUTDOWN XXXXRPM
Engine rotational over speed shutdown. You can program the limit and a bypass alarm time
for it. (section 14.0)
UNDER SPEED
SHUTDOWN (ALARM)
XXXXRPM
Engine rotational under speed shutdown. You can program the limit and a bypass alarm
time for it. In NFPA/EN applications, the alarm does not shut down the engine (section 14.0).
START 1 FAILURE
WARNING
This warning takes place when a start attempt fails to start the engine. This provides
important information in case you have problems in starting the engine. The Be126 will
continuously try to start the engine until the programmed maximum numbers of attempts will
be reached (section 13.0).
START 2 FAILURE
WARNING
FAIL TO START
SHUTDOWN (ALARM)
Fail to start shutdown. The BE126 stops any further starting attempt. You are required to
enter the OFF mode of operation to clear the alarm. In case of fire, try to start the engine by
using the [START 1] or [START 2] push-buttons.
FAIL TO STOP
SHUTDOWN (ALARM)
This alarm triggers if, after a stop sequence, the Be126 detects an
‘Engine Running Status’.
You are required to investigate the problem. You can disable the alarm by setting the option
[OFF]
into
[FAIL TO STOP]
parameter (see section 13.0 & 13.0.6).
BELT BREAK
SHUTDOWN (ALARM)
Engine belt break (or belt driven charger failure) shut down. You can disable the alarm by
setting the option 'OFF' into
[BELT BREAK]
parameter. In NFPA/EN modes, the alarm is
ignored (see section 13.0 & 13.0.5).
UNEXPECTED STOP
WARNING
This alarm triggers in case the engine stops by its own for unknown cause. You are required
to investigate the problem and eventually restart the engine.
TEST FAILURE WARNING
There are three basic sources for this alarm: the engine fails to carry out a complete
automatic test, the drain valve failed to work or, the pressure sensor failed to provide a start
command to Be126. You are required to investigate the source and to repeat a manual test
of the automatic system. To set-up correctly
the ‘TEST’ parameters consult the section 21.0.
