Section 16.0.1

 

BYPASS SWITCH                      

                             OFF

LOW % SHUTDOWN

                             OFF

 

(15s-99mins  / 1-99%)

 

NOTE: the Be126 will not shut down the engine in NFPA/EN modes.

The Be126 triggers the FUEL RESERVE WARNING alarm if you activate the JF-5 input (connected to a low level fuel switch). By programming a [BYPASS SWITCH]                      

time, the engine will shut down providing a FUEL RESERVE ALARM.

The Be126 also, shuts down the engine if you program a [LOW % SHUTDOWN] limit. In this case the Be126 provides a15 second bypass time delay. You are required to connect a resistive sensor to the JM-5 input.

 

 

Section 16.0.2

 

LOW %  WARNING                  

                             OFF

HIGN %  WARNING

                             OFF

 

(limits 1-99%)

 

The Be126 monitors the fuel level, providing a warning, by programming at least one limit. The Be126 provides a 15 second bypass alarm delay. You are required to connect a resistive sensor to the JM-5 input.

Fuel Level Sensor Response Curve.

 

You can edit 6 points for Fuel Level (0-99%) indication and 6 points for sensor resistance (0-1000 OHM). Factory programming complies with VDO /Continental fuel sensor.

Fuel Level Sensor must be connected to JM-5. To display the level measurement you are required to program a setting of ‘Low’ or ‘High’ level (see above).

 

Section 16.0.4

 

POINT 4 LEVEL

                          0%

POINT 4 OHM

                         10 OHM

POINT 5 LEVEL

                         50%

POINT 5 OHM

                        95 OHM

POINT 6 LEVEL

POINT 6 OHM

                     180 OHM

 

 Fuel Level Sensor Response Curve.

 

 

NOTE: If you set all Level % Alarm parameters to OFF (as par default settings), the Be126 will ignore the input JM-5. In this case you are requested,at least, to connect a level switch to the JF-5 input.
