NGINE ROTECTION
The PDM1 should be set up and used by trained
personnel to avoid damages or safety hazards.
Introduction
The PDM1 is a control unit for engine protection and is
used for manual starting and stopping of petrol (gasoline)
or diesel engines.
The PDM1 provides for automatic monitoring and
shutdown of the engine in case of a fault and has
protections for: low oil pressure, high engine temperatu-
re, low fuel level, alternator battery-charger fault, low and
high engine speed.
By turning the selector key to the "ON" position, the
PDM1 is powered up.
The engine control conducts a LED test cycle and
then it set itself up for the starting cycle which is
operated by turning the key to "START" after the
preheating delay (led ref.7 still switched on).
After the "Alarms inhibition delay", the protections are
enabled and, if there are malfunction conditions, the unit
stops the engine.
To proceed with the stopping cycle, turn the key to
"STOP".
Alarms
The "Pressure", "Temperature" and "Fuel level" alarms
are enabled when the engine is running after the alarms
inhibition delay . The "RPM out of limits" alarm is enabled
when
engine running is detected.
With the unit supplied and the engine stopped or the
alarms inhibition time not lapsed, the front LEDs show
the input state, without causing any alarm event.
During the engine operation, it will be stopped at any
alarm event. The tripping is stored and the relative
malfunction LED remains switched on.
In these conditions, no other alarm is displayed except
for the one causing he engine to stop.
Resetting is obtained by removing power from the unit or
by pressing any of the keys at the lapsing of the Stop
time.
