Section 13.0.1

CRANK DELAY                       

                          1 sec

CRANK TIME

                         15 sec

(range: 1-15 seconds)

The [CRANK DELAY] timer delay the crank when required by the engine characteristics. [CRANK TIME] limits the coupling time of the starter motor. NPFA 20 requires a  [CRANK TIME] of 15 seconds. UNI/EN requiree a [CRANK TIME] in between 5 up to 10 seconds.

 

Section 13.0.2

CRANK REST TIME                       

                           15 sec

START ATTEMPTS

                             6

(range: 3-15 seconds /3-15 attempts)

These parameters establish the start sequence of the engine: rest time and maximum number of attempts. NPFA 20 requires a  [CRANK REST TIME] of 15 seconds. UNI/EN requires a [CRANK REST TIME] in between 5 up to 10 seconds.

Section 13.0.3

CRANK VDC (*)                      

                      8.0 VDC

CRANK RPM

                        700

(3-30VDC /300-1000 RPM)

 

(*) In Engine Protection Mode you can connect the ‘D+/W.L.’ of a belt aternator.

The Be126 terminates the crank when voltage of the charger alternator [CRANK VDC] or rotational speed [CRANK RPM] rises above the setting. In NFPA/EN applications, a charger alternator shall not be used. You can connect a speed sensitive relay to terminal JC-10 or a pickup connected to JM8-9 terminals.

 Section 13.0.4

PREGLOW TIME                      

                       OFF

PREGLOW MODE

                       1

(1sec-15mins)

Choose from figure 13.4 the working logic for Pre-glow. To enable the Pre-glow set the option PREGLOW in the menu [MISCELLANEOUS] > [OUTPUT 2 OPTION]. You are required to connect a driver relay to the output JC-1.

Section 13.0.5

STOP SOLENOID

                      2 sec

BELT BREAK                     

                         8.0 VDC

(1s-15mins /3-30VDC)

[STOP SOLENOID]: you are requested to connect a driver realy to the output JC-4.

[BELT BREAK]: Setting to detect a belt break condition of the belt alternator. The option OFF disables the alarm. In NFPA/EN modes the alarm does not shut down the engine.

Section 13.0.6

FAIL TO STOP

                           OFF

ALARMS BYPASS                   

                        10 sec

 

(limits 3.0-30.0Vdc/

1-99seconds)

[FAIL TO STOP]: option ON

triggers the alarm in case Be126 fails to stop the engine. The [ALARM BYPASS] timer allows Be126 to ignore the Oil Pressure /Temperature alarms. In NFPA/EN modes these alarms do not shut down the engine.

Section 13.0.7

HIGH BATTERY V.

                         15.0 VDC

LOW BATTERY V.                  

                        11.0 VDC

 

(limits 3.0-30.0Vdc)

You can set High/Low battery voltage limits. To trigger the alarm, the battery voltage must exceed the limit for at least 30 seconds.

 

 

Section 13.0.8

START ENABLE

                         6.0 VDC

 

 

(limits 3.0-30.0Vdc)

You can exclude the battery from the start sequence if the voltage is lower than [START ENABLE]. In the extreme case that both batteries are lower than the setting, the Be126 will trigger immediately the starting failure alarm. You are required to start the engine manually.
