Automatic start-up process
The automatic start-up consists of a sequence of six consecutive start-up attempts. Each attempt lasts
15 seconds and is followed by a pause of 10 to 15 seconds. After each start-up attempt, the other battery is
used for the following attempt. Even if there is no additional need on the float or key switch level, start-up
attempts continue. The number of attempts with each battery will be constantly indicated on the LCD.
All successful start-ups are signalled by a green LED (Fig. 2, pos. 3) and the output “running” is activated.
After six unsuccessful start-up attempts, an alarm signal is emitted, the output “failure to start” is activated and
the red “failure to start” LED is turned on (Fig. 2, pos. 5) as well as the yellow LED which signifies “attempt at
manual start-up” (Fig. 2, pos. 22) (see test of start-up device 6.2.1).
After a successful start-up sequence or after a phase of “failure to start”, the yellow LED named “Operate the
test button for manual start-up if the indicator light is turned on” is turned on. (see device start-up test 6.2.1).
Non-automatic mode
The key switch is not in the “Auto” position. Consequently, the corresponding pressure switch cannot activate
automatic start-up.
If neither of the two key switches is in the “Auto” position, then the start-up tank also cannot activate automatic
start-up. This operating mode is signalled by the red LEDs (Fig. 2, pos. 32, 33). Furthermore, the output
“NON-AUTO MODE 1/2” is active.
Manual mode
To perform a manual start-up, place one of the key switches in the “Man” position. The manual start-up (like the
automatic start-up) consists of a sequence of six consecutive start-up attempts. Each attempt lasts 15 seconds
and is followed by a pause of 10 to 15 seconds. After each start-up attempt, the other battery is used for the
following attempt.
Even when the key switch is not in the “Man” position, the start-up attempts continue.
Deactivation mode
To switch off the diesel motor, at least one of the key switches must be in the “0” position. As soon as the
pressure switch (or the float switch) is no longer activated, the diesel motor can be switched off by means of
the “OFF” button (Fig. 2, pos. 21).
Emergency start
Start by lifting the emergency start button protection cap (Fig. 1, pos. 12 et 13).
Subsequently, to start the diesel motor with battery no. 1, press the button “battery 1 emergency start”, and
keep the button pressed until start-up.
To start the diesel motor with battery no. 2, press the button “battery 2 emergency start”. In this start-up mode,
the starter is fed directly from the batteries.
Manual start-up device test
After a start-up sequence (manual or automatic) or after a failure to start, the yellow LED (Fig. 2, pos. 22)
recognised by the following indication is turned on: “OPERATE THE MANUAL START TEST BUTTON IF THE
INDICATOR LIGHT IS TURNED ON”.
In this case, the corresponding button must be pressed (Fig. 2, pos. 23) to perform the start-up device test.
