                              OFF
HIGH °C WARNING
                              OFF

 

LOW °C WARNING
                              OFF

 

 

(0- 250 Degree Celsius)

 

 

The Be126 triggers a HIGH TEMPERATURE ALARM (or a SHUTDOWN) when the coolant temperature rises above the setting.

 

The Be126 triggers a LOW TEMPERATURE WARNING when the coolant temperature drops below the setting. The alarms are ignored during the [ALARMS BYPASS] time (see section 13.0 >13.0.6)

 

 

 

NOTE: in NFPA/EN modes the Be126 wil not shutdown the engine.

Coolant temperature response curve

 

 

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).

Coolant temperature response curve.

 

 

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 at least a temperature switch to protect the engine. The digital input is on terminal JF-3. The Be126 triggers an alarm when you connect the input to the battery minus (normally open contact).
