The Be126 triggers a
[HIGH TEMPERATURE ALARM]
(or a
[HIGH TEMPERATURE WARNING]
) when the
coolant temperature rises above the setting. These alarms are ignored when the engine is not
running and during the
[ALARMS BYPASS]
time (see section 13.0 >13.0.6).
The Be126 triggers a
[LOW TEMPERATURE ALARM]
when the coolant temperature drops below the
setting. The alarms is continuously monitored, even when the engine is not running.
NOTE: in NFPA/EN modes the Be126 will not shutdown the engine.
IMPORTANT NOTE ABOUT COOLANT TEMPERATURE MEASUREMENT
In order to make Be126 able to display the engine COOLANT TEMPERATURE, in addition to the TEMPERATURE sensor connected to
JM-3, you are required to set up at least one TEMPERATURE alarm (example
[LOW °C WARNING]
).
By keeping all alarm with the option to
[OFF]
mode, the display will not indicate the temperature measurement.

You can edit 6 points for coolant
temperature (0-250 °C) and 6
points for the resistance of the
sensor (0-1000 OHM). Factory
programming complies with VDO
sensor. The coolant temperature
sensor must be connected to the
JM-3
input. To display the coolant
temperature you are required to
program at least one alarm for
coolant temperature (see above).

If you set all coolant temperature
alarms to OFF, the Be126 will
disable the coolant temperature
measurement on display. In this
case you are requested to connect
a temperature switch to protect the
engine. The Be126 triggers an
alarm when you connect the input
terminal
JF-3
to the battery minus
(You are required to use a
normally open contact).
