To start the engine using the BATTERY SET 1 push the [START 1] button
Push the [START 2] button if you want to use the BATTERY SET 2
STOPPING THE ENGINE IN THE MANUAL MODE OF OPERATION
To stop the engine you have to push the [OFF] button. The Be126 removes the power to the ‘Fuel Solenoid’ (output JC-8). In case you use an energized to stop solenoid, the Be126 activates the output JC-4 according to [STOP SOLENOID] timing. When you push the [OFF] button, you also enter the OFF mode of operation. The Be126 clears all alarms and resets the system.
An optional way to stop the engine is to enter the AUTO mode of operation. If there is no fire alarm (all sources of start have been returned to normal) the Be126 will shut down the engine after the [STOP DELAY] timing. Please note that factory programming for [STOP DELAY] is OFF (the engine will not stop automatically).
In the NFPA application, you can not program a time lower than 30 minutes.
THE NFPA 20 AUTO MODE
Push the [AUTO] push button until the yellow AUTO indicator illuminates (you can connect a lamp to JB-4 output); the display will indicate the message [AUTO].
The engine starts when the Be126 detects one of the following conditions:
- the water pressure switch is open (digital input JF-4)
- the water level switch is open (digital input JF-7)
- the water pressure drops below the [START DEMAND] setting (see 19.01 & Input JM-1)
When the Be126 detects a water pressure drop, the yellow indicator >LPS< blinks. The display will switch the message [START DEMAND OFF] to [START DEMAND ON]. The Be126 will initiate the start sequence after a [START DELAY] bypass time (see the [MISCELLANEOUS] menu 21.0.1). Depending on your settings, the engine will run at idle speed or immediately at nominal speed.
When the engine is running, use the display arrows to browse the instruments. If you get lost during navigation, push the [HOME] button: the display will open the ‘System Status Page’. Push the [OFF] button to stop the engine.
We remind you that according to NFPA 20 specifications, only an OVERSPEED condition can shut down the engine. All the other alarms provide only a warning.
The Be126 will periodically test the engine if the scheduler is correctly programmed. The display will indicate the message [TEST SCHEDULER]. After the test, the engine will stop based on your settings. You can analyze all events by browsing the [EVENT HISTORY] menu.
When the Be126 is in the AUTO mode of operation, you can test the automatic system by pushing the [PUMP TEST] button. The Be126 will activate the drain to initiate a test.
To find out more about the AUTO mode of operation, consult Chapter 12 of the NFPA 20 Standard and sections 10.9.7---.13 of the EN 12845 Standard.
THE NFPA 20 TEST MODE
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 water pressure drop.
5) The engine will run and eventually 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 section 21.0.2 to change the alarm delay if necessary).
THE NFPA 20 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 must 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.
NFPA 20 FIRE PUMP CONTROLLER HARDWARE OVERVIEW
The Be126 Fire Pump Controllers from Bernini Design are designed to control and monitor 12 or 24-volt, diesel fire pump engines used in NFPA 20 or UNI-EN 12845 compliant fire fighting applications. Firstly, the Be126 is among the most technically advanced diesel engine controllers. Secondly, the Be126 features a state-of-the-art multiprocessor structure providing an embedded water pressure data logger capable of storing up to 31 days of data recording.
Thirdly, the Be126 interfaces with standard diesel or SAE J1939 compatible engines. Additionally, the Be126 fire pump controller monitors, displays, and records fire pump system information. The Be126 diesel engine fire pump controller is designed to start the diesel engine automatically from water pressure control or non-automatically from manual electric control. Furthermore, this type of diesel engine fire pump controller maintains the full charge on engine starting batteries, monitors engine and system conditions, and initiates a weekly program test of the system. Be126 monitors analogue or digital water pressure or water level transducers. Be126 can provide mathematical calculations over the pressure, providing MIN, MAX, and AVG values. By enabling the Engine Protection Mode software you can use the Be126 controller on a standard diesel engine pump water station. In conclusion, the Be126 controller features RS232 and RS485 serial interfaces that provide ASCII and MODBUS protocols.
This fire fighting system controller's reliability of operation is not adversely affected by dust accumulations, temperature variations, humidity, fungus, or adverse elements. The BE126 is extremely strong and insensitive to vibrations. Its basic structure is made of steel and carbon fibre. A NEMA Type 2 drip-proof is provided with IP54 ingress protection.
TO COMPLY WITH NFPA20 THE CONTROLLER MUST DISPLAY THE VOLTAGE AND CURRENT OF EACH BATTERY. BY USING THE MCBXX BATTERY CHARGER, THE BE126 READS THE CHARGING CURRENT VIA RS485-MODBUS.
