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

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.

4
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.
