fire fighting controller alarm system

Fire fighting controller alarm system

The Be126 features Light Emitting Diodes to indicate alarms; additional detailed information a provided by the graphic display. You can connect an audible horn alarm as well. If allowed by your application you can use the  [HOME] push-button to silence the horn. Finally, all alarmS are recorded in the Event Log Memory together with timestamp.   NFPA 20 CONTROLLER ALARM LIST

Instructions in case of alarm(s):

  • Look at the front panel and take note about LED indicators and message(s) on the display.
  • Push the [HOME] push-button to silence the horn. Push the [OFF] push-button to cancel the alarm.
  • Consult the following sections for further information and remove the cause of the alarm.
The list of the alarms is indicated below on the left side. Shutdowns are serious alarms and will stop the engine; warnings and pre-alarms will allow the engine to run. In NPFA mode only over-speed alarm is allowed to shutdown the engine.
 
 Clock and Memory alarms

 

CLOCK  ERROR WARNING               

Real time clock failure or wrong programming. This alarm takes place in case you failed to program the Real Time Clock before programming the Scheduler (see section 10.2). Always program the RTC first, then program the scheduler.

 

PARAMETER ERROR       

Error in a parameter. Try to re-program the parameter correctly.

Check the upper or lower limit or the allowed options for it.

CAN BUS ERROR WARNING          

Failure of the Canbus communication. Check the wiring or the CAN bus settings.

RED LAMP SHUT WARNING         

Failure of  engine detected by the ECU. Consult the user manual of the engine. This alarm does not shut down the engine.

 

MODBUS TIME OUT 1
MODBUS TIME OUT 2

          

Failure of the MODbus communication. Check the wiring & MOD bus settings of the battery charger 1 & battery charger 2.

BE126 FAILURE        

It indicates a memory error or a severe damage of the Be126 controller. You can try to disconnect the DC supply for a while. If the problem persists, you are required to return the controller to Bernini Design for service.

 

 
Battery & Battery Charger alarms

 

BATTERY CHARGER 1
ALARM (FAILURE)              

These alarms are sent via MODBUS by the battery chargers. It is about a general failure of the battery charger. These alarms energize also when you connect to the battery minus the alarm inputs JF1 or JF2. These inputs are used in case your battery chargers do not feature a MODBUS communication.

 

BATTERY CHARGER 2
ALARM (FAILURE)              

 

LOW BATTERY 1
WARNING

These are general purpose adjustable alarms about battery 1 & battery 2. You can set a ‘low limit’ and a ‘high limit’ for each battery. An alarm bypass of about 15 seconds is automatically provided.

HIGH BATTERY 1
WARNING
LOW BATTERY 2
WARNING
HIGH BATTERY 2
WARNING

 

 

 

 
Emergency Input

 

EMERGENCY INPUT SHUTDOWN  

This alarms triggers when you connect to battery minus the terminal JF-8. This alarms shuts down the engine immediately.

 

 
Miscellaneous engine alarms

 

PICK UP  FAILURE              

The alarm triggers when the detected speed is lower than CRANK-RPM setting.To enable this alarm you are required to set the pickup teeth-number and to set a CRANK RPM limit. The Be126 provides a 20 second alarm bypass.  

 

OVER SPEED
SHUTDOWN   XXXXRPM

 

Engine rotational over speed shutdown. You can program the limit and the bypass alarm time.

UNDER SPEED
SHUTDOWN (ALARM) XXXXRPM

 

Engine rotational under speed shutdown. You can program the limit and the bypass alarm time. In NFPA/EN application, the alarm does not shut down the engine.

START 1 FAILURE WARNING                

 

This warning takes place all the time a start attempt is not able to start the engine. This provides important information in case you have problems in starting the engine.

START 2 FAILURE WARNING                                 

 

FAIL TO START
SHUTDOWN (ALARM)                

 

Fail to start shutdown. The BE126 stops any further starting attempt. You are required to enter the OFF mode of operation to clear the fault.

 

FAIL TO STOP
SHUTDOWN (ALARM)     

              

This alarm triggers if after a stop sequence, the Be126 detects an engine running status. You are required to investigate the problem.

 

BELT BREAK 
SHUTDOWN (ALARM)      

              

Engine Belt break (or Charger failure) shut down. You can disable the alarm by setting the option to 'OFF' into BELT BREAK parameter.

In NFPA/EN mode, the alarm is ignored.

 

UNEXPECTED STOP WARNING

             

This alarm triggers in case the engine stops by its own without an apparent cause. You are required to investigate the problem and eventually restart the engine.

 

TEST FAILURE WARNING

 

             

There are three basic sources for this alarm: the engine fails to carry out a complete automatic test, the drain valve failed to work, the pressure sensor failed to provide a start command to Be126. You are required to investigate the source and to repeat a manual test of the automatic system.

 

 

 

 
Mains alarms
 
VAC FAILURE

This alarm triggers when a parameter of the mains (voltage. frequency or other) is no longer within the admitted limit.  

 

 

 
Temperature alarms
 
LOW COOLANT °C 
WARNING   XXX°C
 
HIGH COOLANT °C 
WARNING XXX°C
 
HIGH COOLANT °C 
SHUTDOWN XXX°C
 
You can set a low or/and high temperature limits for the engine coolant. The alarms are ignored during Alarms-Bypass timing. Coolant temperature information is provided by CAN bus or by a sensor connected to input JM-3.
The ‘XXX’ notation stands for the temperature alarm recorded in the moment that the alarm triggered.
COOLANT SENDER
OPEN   
 
It indicates the failure of the temperature sensor connected to JM-3 when the measured resistance is over 2000 Ohm.
TEMPERATURE  SW.  SHUTDOWN (ALARM)                  
It indicates the failure of the temperature sensor connected to JM-2 when the measured resistance is over 2000 Ohm.
 
LOW AUX °C
WARNING    

 

HIGH AUX °C
WARNING    

 

HIGH AUX °C
SHUTDOWN      

           

You can set an auxiliary temperature warning and / or a shutdown. You are required to connect a sensor to input JM-2. The alarm is always active except in OFF mode of operation. The engine does not shut down in NFPA20/EN12845 mode.

It indicates the failure of the temperature sensor connected to JM-2 when the measured resistance is over 2000 Ohm.

 

 
Fuel Level alarms

 

FUEL RESERVE
WARNING

 

Fuel switch alarm monitoring.

The Be126 monitors the level of the fuel in the tank. You can set warnings about fuel level. The default setting provides a warning only. You can set up a shutdown by programming a timing into the delay TANK EMPTY timer. The Be126 shuts down the engine if the level drops (level sensor).

 

FUEL RESERVE
