2.0 ALARMS LIST
[DISPLAY]
ALARM DESCRIPTION
NOTES
[bELt]
Engine Belt break or Charger failure shutdown. The Be172 triggers this
alarm and shuts down the engine if the input (D+/W.L) is continuously
below 3Vdc for at least 20 seconds.
Check for the belt
or the charger
alternator.
[°C]
Engine High-Temperature alarm. The Be172 triggers this alarm and
shuts down the engine if the switch input (°C) is closed for at least one
second.
Check the engine
cooling system.
[ALAr]
Emergency alarm. The Be172 triggers this alarm and shuts down the
engine if the switch input (ALR) is closed for at least one second.
Check the
emergency
button status.
[FuEL]
Fuel level alarm. The Be172 triggers this alarm if the switch input (FUEL)
is closed for at least one second. Based on the settings of the parameter
[P3], the BE172 triggers a warning (it features auto-reset) or shuts down
the engine after a programmable time.
Refuel the tank
[ALr1]
Alarm 1. The Be172 triggers this alarm if the switch input (ALARM1) is
closed for at least one second. Based on the settings of the parameter
(P4), the BE172 triggers a warning (it features auto-reset) or shuts down
the engine after a programmable time.
Check the Alarm
1 source.
[oiLP]
Low oil pressure. The Be172 triggers this alarm and shuts down the
engine if the oil pressure switch connected to the (OIL) input is closed for
at least one second. This alarm is ignored for 15 seconds after starting
the engine.
Check the oil
level.
[FAIL]
Fail to start alarm. The Be172 triggers this alarm and shuts down the
(FUEL) output if it does not detect, within 20 seconds, a valid source of
engine running from terminal (D+/WL) or a valid transition of the (OIL)
input (closed-to-open).
Check the engine
or check if have
forgotten the KEY
in the ON
position.
[Err-]
The Be172
fails to enter the ‘PROGRAM MODE’ due to an erroneous
inputs setup.
Check the
programming
instructions.
[Err1]
Failure of the memory.
Check the supply and retry programming. If the error persists,
replace the Be172.
[Err2]
The supply is lower than 10V. The Be172 denies access to the memory.
Check the dc supply.
[EE.Er]
The Be172 failed the memory initialization routine during the power on. Remove the supply
for a few seconds. If the error persists, replace the Be172.
3.0 FUEL SOLENOID & STOP SOLENOID
In order to stop the engine, we recommend that you use a
FUEL SOLENOID
(energized to run)
.
This
solenoid must be connected to the output (FUEL) via a pilot relay. If for a particular application, you use
a
STOP SOLENOID
(energized to stop), you are required to set up the adjustable parameter [P2] as
indicated in the programming instructions. Connect the
STOP SOLENOID
to output (ALARM) via a pilot
relay as indicated in the wiring diagram. The Be172 will energize the output for the programmed time.
When you use the output (ALARM) to drive a
STOP SOLENOID
, the
ALARM
function output will no be
longer available. In other words, the
STOP SOLENOID
output shares the same output used for
ALARM.
Factory setting for the (ALARM) output is
ALARM MODE
