LOW BAR SHUT.
OFF
(0,1- 20.0 BAR)
The Be126 triggers the
[LOW OIL BAR WARNING]
(or
[LOW BAR SHUTDOWN]
) alarm when the oil
pressure drops below the setting.
The alarm is ignored during the
[ALARMS BYPASS]
time (see13.0 &13.0.6).
NOTE: in NFPA/EN modes of operation, the Be126 will not shutdown the engine.
IMPORTANT NOTE ABOUT OIL PRESSURE MEASUREMENT
In order to make Be126 able to display the engine OIL PRESSURE measurement, in addition to the oil pressure sensor connected to JM-4,
you are required to set up at least one alarm of oil pressure (example
[LOW BAR WARNING]
).
By keeping both alarms to
[OFF]
, the display will not indicate the oil pressure measurement.

Oil pressure response curve
You can edit 6 points for oil engine
pressure measurement (0-20.0
BAR) and 6 points for the
resistance of the sensor (0-1000
OHM). Factory programming
complies with VDO sensor. The
oil pressure sensor must be
connected to the
JM-4
input. To
display the oil pressure you are
required to program at least one
alarm about oil pressure (see
above).

Oil pressure response curve
If you set all oil pressure alarms to
[OFF]
, the Be126 will disable the oil
pressure measurement on display.
In this case you are requested to
connect at least a pressure switch
to the terminal
JF-9
. The Be126
will trigger an alarm when you
connect the
JF-9
to the battery
minus (a normally closed contact
is required).
