1.0 Functional MODES
The BE26A module is a controller for diesel-engine driven pumps for fire-fighting applications or for general purpose applications. The BE26A complies with NFPA-20 regulations. The BE26A operates in a NFPA-20 functional mode if the terminals JM5 and JM6 are open. By connecting the terminals
JM5 and JM6 together, the BE26A operates in ‘Engine Protection Functional Mode’ (see sections 5.0 and 12.0). See table 1
TABLE 1: Functional Mode true table (see diagram in section 15.0 for wiring)
NPFA-20 Functional Mode
(terminal JM5 and JM6 open)
Engine Protection Functional Mode terminal JM5 and JM6 connected together
the green LED 'NFPA-20' illuminates the red LED 'Engine Protection' illuminates
The programmable parameters of the Be26A are described in the sections 7.0 and 8.0.
The Be26A is delivered with factory setting parameters (hereinafter ‘DEFAULTS’). Before using the unit, verify that the programmed parameters meet your requirements.
2.0 MODES of operation
The key switch on the front panel has 3 positions ‘AUTO’-‘MAN’-'OFF'. In ‘AUTO’ mode, the Be26A starts and stops the engine according to the programmed parameters. Be26A monitors the status of the Pressure Switch
(section 12.0) and Remote Test switch (section 13.0). The key of the key-switch is removable only in AUTO mode. The Be26A can operate in NFPA-20 mode (JM5-6 open), or Engine Protection Mode (JM5-6 connected together). The Be26A features ‘START’ and ‘STOP’ pushbuttons to control the engine manually. The modes of operation are remotely transmitted by means of dedicated outputs: JB2 (AUTO) and JB3 (MANUAL). External lamps or relays can be used for additional indications.
2.1 AUTO mode
Start cycle in NFPA-20 MODE (terminals JM5-6 open, green LED Master=ON)
The engine starts in 'AUTO' in case of low water pressure. A pressure switch must be connected to the JC10 input. A programmable delay is provided by the parameter [0.5"] (see section 8.0). The BE26A initiates the start when the Pressure Switch opens. The engine will continue to run independently of the pressure switch status. In
AUTO mode, it is possible to START the engine without delay by using a REMOTE TEST switch (input JM10).
The engine stops when the contact of the REMOTE TEST switch opens. The Pressure Switch has priority over the REMOTE TEST.
Stop cycle in NFPA-20 MODE
To stop the engine, turn the KEY to OFF. The engine shuts down automatically only in case of OVERSPEED or EMERGENCY. The REMOTE TEST does not stop the engine if the pressure switch is open.
Start cycle in Engine Protection MODE (JM5-6 connected together, red LED ‘SLAVE’=ON)
The engine will start in 'AUTO' if a loss of pressure occurs. To initiate an automatic engine start, a pressure switch must be connected to the JC10 input. A programmable delay is provided (parameter [0.5"], see section
8.0). The Be26A starts the engine when the Pressure Switch opens. The engine stops if the Pressure Switch closes. A programmable delay to stop the engine is provided (parameter [1.5"], see section 8.0). The REMOTE
TEST can be used to start and stop the engine without delays.
3
Stop cycle in Engine Protection MODE (JM5-6 connected together)
The engine stops in one of the following ways:
- Immediately, in case of ALARM (*) (see section 5.0)
- After a delay, if the PRESSURE SWITCH (*) closes the contacts
- Immediately, if the REMOTE TEST switch opens the contacts
(*)Note. The BE26A can shutdown the engine according to parameters [L.07] and [I.01], as described in the section 8.0.
2.2 MANUAL mode
To control the engine in manual, use the 'START' and 'STOP' pushbuttons. To select the MANUAL mode, turn the Key-Switch into MAN.
In accordance with the NFPA-20 standard, it is not possible to remove the key in MANUAL mode. The STOP button is always disabled in NFPA-20 MODE. To stop the engine, turn the key to OFF mode.
2.3 OFF mode
If the key-switch is in the ‘OFF’ position, all operations of Be26A are inhibited, and the engine does not start.
Turn the key-switch to OFF to cancel the alarms and stop the engine. In OFF mode, it is possible to program the parameters (see section 6.0). It is not possible to remove the key in OFF mode. In OFF mode, the display turns off automatically afters a few seconds. To restore the display, push the [ALARM RESET] pushbutton: the display will indicate the HOUR METER.
2.4 TEST of the LAMPS (LED indicators)
Turn the key to OFF. Push and hold for about 5 seconds the [ALARM RESET] pushbutton, the LEDs and
DISPLAY will turn on. Release the button to turn off the indicators and display.
3.0 Front panel description
The BE26A features a 3 digit display, pushbuttons, key-switch and Led indicators (see section 17.0). The display may indicate one of the following:
3.01 Program (hour meter)
The display indicates the number of run hours. The resolution is 1 hour. When the count is over 999, a decimal point (on the right side of the display) will indicate that the indication has to be multiplied by 10. In order to clear the hour count, (e.g. after a replacement of the pump) push the ‘STOP’ and ‘ALARM RESET’ pushbutton simultaneously for at least 10 seconds in ‘MAN’ mode, until the message [dEL.] appears. If the number of running hours of the engine is over 9999 ( [ 999.] on display) the counter will start to count from zero.
3.02 TIMER indications
The display indicates the count down of the timers [0.5"] (delay to start) and [1.5"] (delay to stop, see section
8.0). The timers are programmable up to 9 minutes. The display indicates the time in the form
[Minutes.Seconds].
3.03 Battery Alarm indications
The display will indicate, in case of failure of the Battery set, the message [bt.1] or [bt.2]. The external low voltage relays must be connected to the JF4 and JF8 inputs (see section 4.0).
The BE26A removes the message automatically if the battery returns to normal operating range.

9.0 Starting cycle
For safety reasons, the BE26A supports two independent battery circuits. While performing several starting attempts, the BE26A switches from one battery system (from one crank motor) to another, so as not to exhaust one system too much.
Start 1 drives the electric Start pulses are alternated until the engine has been successfully started
18
motor supplied by the first battery system.
Start 2 drives the electric motor supplied by the second battery system.
10.0 Engine running detect
The green LED 'RUN', indicates that the engine is running and the starter motor is disabled. The crank must be terminated when the engine reaches its ignition speed in a way to protect the starter from damage. When the engine is not running, the alternator voltage is 0V. By starting the engine, a DC current of approx. 200mA flows into the D+ terminal. The engine is not running but, a voltage of approx. 0.8 to 1.5V appears. The Voltage of the
Charger Alternator rises as soon the engine begins to run due to cranking. When the engine reaches its ignition speed (crank termination moment), the alternator voltage rises to 10V-12V. The factory setting to stop the starter motor is 8V.
If the engine is running at nominal speed, the alternator voltage output is approx. 14V (28V for 24V battery systems). Section 11.0 describes how to calibrate the Crank termination.
11.0 Engine running Calibration
Use the following procedure:
A) Turn the key-switch to 'MAN' position.
B) Turn the trimmer T1 (near the terminal JM4-5, see section16.0) to fully c.c.w.
C) Push the ‘START’ push-button until the engine starts
D) Rotate slowly clock wise until the green LED 'RUN' on the front panel illuminates.
E) Verify the stability of the LED light 'RUN'
F) Stop the engine by pressing the 'STOP' button.
G) Disconnect the FUEL SOLENOID, then push and hold the ‘START’ pushbutton in order to crank the engine continuously. If the LED ‘RUN’ illuminates during cranking, turn the rear trimmer c.c.w. until the LED turns off.
H) Connect the fuel solenoid.
I) Turn the key to AUTO, and start the engine using the ENGINE TEST input. Check to see that the BE26A has disconnected the starter motor properly.
NOTE: in fire-fighting application (NFPA-20), a speed sensitive relay should be connected to the JM4-5 input. You may not use the Charger Alternator supply to detect Crank Termination.
12.0 Line Pressure Switch Monitoring
In AUTO mode, the BE26A monitors the status of the Pressure Switch (JC10 input) as follows:
12.01 NFPA-20 Mode
The status of the Pressure Switch of the water is indicated by 2 LEDs. A green LED indicates a normal condition (pressure ok) and the a red LED indicate no pressure in the system.
- If the switch remains open for at least the programmed time, (see section 8.0, parameter '0') the BE26A starts the engine.
- After starting, the engine will continue to run even if the swirch closes.
- The engine will continue to run even in case of alarm (see section 5.0).
- In case of STARTING FAILURE, OVERSPEED or EMERGENCY, the engine shuts down. The alarm(s) must be cancelled manually.
12.02 Engine Protection Mode:
The status of the Pressure Switch of the water is indicated by 2 LEDs. A green LED indicates a normal condition
(pressure ok) and the a red LED indicate no pressure in the system.
- If the switch remains open for at least the programmed time, (see section 8.0, parameter '0') the BE26A starts the engine
19
- After starting, if the switch remains close for at least the programmed time, (see section 8.0, parameter '1') the
BE26A can stop the engine (see the options of the parameter 'L' in the section 8.0).
- If the engine shuts down, in case of alarm, you have to restart the engine.
- The engine can continue to run in case of alarm only if allowed by programming (see TABLE 2, section 5.0)
13.0 Remote test
A switch connected to the JM10 terminal controls the start-stop cycle of the engine. External On/Off switches, level switches or timers can be connected. The engine starts and stops immediately. The TEST can be performed only in AUTO mode of operation.
13.01 NFPA-20 Mode
- If the input is grounded, the BE26A starts the engine immediately.
- If the input is opened, the BE26A stops the engine immediately.
- In case of alarms, the Engine Test will be ignored. The alarm(s) must be cancelled by operator intervention.
- During the Engine Test period, the engine will continue to run even in case of alarm according to TABLE 2
(see section 5.0).
- If an alarm shut down the engine, the Pressure Switch can restart the engine automatically (except in cases of
STARTING FAILURE, OVERSPEED or EMERGENCY).
13.02 Engine Protection Functional Mode:
- If the input is grounded, the BE26A starts the engine immediately.
- If the input is opened, the BE26A stops the engine immediately.
- During the Engine Test period, the BE26A monitors the alarms according to the parameters [I.01] and [L.7]
(see section 8.0).
- In case of alarms, the Engine Test will be ignored. The alarm(s) must be cancelled by operator intervention.
- If an alarm shuts down the engine, the Pressure Switch cannot restart the engine. The alarm(s) must be cancelled by operator intervention.
13.1 Automatic Periodic Test
To set-up the Automatic Periodic Test, program the parameters [A.--] and [b.5”] as indicated in the section 8.0.
The parameter [A.XX ] indicates the number of days between tests, and the parameter [b.XX] indicates the number of minutes to run the engine. The timer that counts the days starts to count when the power supply is applied.
To see the count down of the timer turn the key to AUTO, and, if the engine is not running, press the ALARM
RESET: the display will show the message [tSt] for a short time, and the message [DAYS.HOURS] at the end.
The timing accuracy is +/- 0.5% (within+/-8 min/day). If a better accuracy is required, an external clock-switch should be connected to the REMOTE TEST input.
