GLOW PLUGS PREHEATING
A
CTIVATED BEFORE STARTING
(GLOW PLUG
IS SHOWN ON THE DISPLAY
)
The duration of the preheating action can be set, the preheating action ceases before the beginning of the
starting process. The preheating control is disabled at the factory since it has been programmed to zero
seconds.
When the call contact closes and the DELAY AFTER CALL CLOSED has elapsed,
the control unit controls the glow plugs (if preset) and then the starting. If preset, the motor pump stays on
idle for the whole ENGINE WARMING
, time, when this time has elapsed the motor pump reaches
and maintains the preset working pressure. When the call contact opens once the STOP DELAY after
CALL OPENING has elapsed, if preset the motor pump slowly decelerates, when the motor pump is on
idle the ENGINE COOLING
time starts.
When this time has elapsed the motor pump stops. During its operation the motor pump is protected from
the faults controlled by the probes connected to the control unit.
STARTING WITH START BUTTON
To start, a pulse on the button is sufficient.
Blocks the startup cycle if the pump has not started up after the fourth pulse.
It is obtained with measurement of the voltage and frequency of the battery charging alternator. Disables
the starter motor.
The priming pump starts; when the priming probe senses the presence of water, the pump stops and after
15 seconds the engine starting begins.
This takes place on closing of the CALL contact, or with Timer or SMS.
Before beginning the starting process, a buzzer is activated for 8 seconds, and after a 3-second pause the
starting process begins. To facilitate startup, a special circuit emits a series of four, 5-second pulses, with a
5-second delay between each pulse.
To activate the
control unit press
the button.
The function selected with the key is
shown by the associated warning light.
•AUT Automatic pressure control.
•OFF
The engine cannot be started and if
running it is stopped.
•MAN Operation without automatic
pressure control.
