Be126 NFPA20 Installation Manual V4XX - 03 Nov -2018 page 10
2.4 TEST mode of operation description !!! WARNING: ENGINE MAY START IMMEDIATELY !!!!
Be126 offers several ways of testing. It depends on the application: NPFA 20, EN12845 or ‘Engine Protection
Mode’. Follow the instructions.
2.4.1 UNI EN 12845 MANUAL TEST FACILITY
Every time you stop the engine after an automatic start, or after an automatic start shutdown, you are required to
manually verify the circuits of the automatic start. You are required to wire an external push button to terminal
JF-6 (Pump Manual Test Switch) and to connect a lamp to terminal JC-4 (Manual Start Lamp).
When the condition to make the test comes true, the Be126 turns on the lamp 'OPERATE MANUAL START TEST
BUTTON IF LAMP IS LIT'. After carrying out the test, the Be126 turns off the lamp.
2.4.2 UNI EN 12845 RESTARTING TEST UTILITY (Weekly Test)
When the Be126 is in AUTO mode of operation, you have to periodically test the automatic system. Follow the
instructions:
•- Push the [PUMP TEST] button.
•- The display indicates the message [TEST START].
•- The Be126 initiates the test by activating the DRAIN VALVE (output JB-5).
•- The Be126 will start the engine when the sensor detects a drop of pressure (*).
•- The engine will run for 20 minutes (you have to program the auto shut down).
When you stop the engine, or after the automatic shutdown, the Be126 will activate the external lamp: 'OPERATE
MANUAL START TEST BUTTON IF LAMP IS LIT'. You are required to start manually the engine. Once the engine is
running, the Be126 will turn off the lamp. We recommend that you consult the sections 10.9.7.1-2-3-4-5 of the
UNI EN 12845 Standard.
(*) Note. If, after a minute time, the pressure fails to drop down, the Be126 will trigger the alarm [TEST FAILURE
WARNING] (see the section 21.0.2 to change the alarm delay if necessary).
2.4.3 NFPA 20 TEST FACILITY (Random Test)
When the Be126 is in AUTO mode of operation, you can carry out a test of the automatic system:
1) Push the [PUMP TEST] button.
2) The display indicates the message [TEST START].
3) The Be126 activates the DRAIN VALVE (output JB-5) to initiate a test.
4) The Be126 will start the engine when the sensor detects a drop of pressure (*).
5) The engine will run and eventually will stop according to your settings.
(*) Note. If, after a minute time, the pressure fails to drop down, the Be126 will trigger the alarm [TEST START] (see
the section 21.0.2 to change the alarm delay if necessary).
2.4.4 NFPA 20 / UNI EN12845 TEST FACILITY (Weekly Test)
The Be126 features a [TEST SCHEDULER] menu that will weekly exercise the diesel engine (see 8.0). You can
program a day of the week, hour and minutes to start the engine. You have to program in the same day, hour
and minutes to stop the engine. At the programmed date & time, the ‘scheduler routine’ will activate the DRAIN
VALVE (output JB-5) and will display the message [TEST SCHEDULER].You can program a [TEST FAILURE
WARNING] alarm timeout in case the system will not trigger a start (see the [TEST FAILURE] in section 21.0.2).
Once started, the engine will run for the programmed time of the [TEST SCHEDULER] menu . The [EVENT HISTORY]
will record all events indicating date & time. The embedded data logger will record the variation of the water
pressure (supposing you connected and correctly configured a water pressure transmitter).
We recommend that you consult the chapter 12 of the NFPA 20 Standard.
