Operation
When the key is turned in the switch to position 1B an efficiency test
is performed, for 5 seconds, on all the indicator lights, with the
exception of the “Pre-post heating” indicator, while at the same time
the beeper sounds.
During start-up and for the following 15 seconds, all synoptic functions
are disabled; after this period, each critical state detected by the
sensors provided on the engine will result in the relevant indicator
lighting up.
Some alarms, which are of critical importance for efficient running of
the engine, will not only light the relevant optical indicator, but will also
start the beeper and cause automatic shutdown of the engine:
- Maximum allowed rotation speed exceeded
- Coolant temperature high
- Oil pressure low
- Engine coolant level low.
ENGINE PRE-HEATING (optional)
(230 V, single phase electrical device)
The engines for which low temperature start-up and immediate
delivery of power are required may be fitted with a 230 V single phase
electrical heating device, which allows the temperature of the coolant
to be raised to or maintained at suitable values. The device is fitted
with a thermostat to cut the power supply when the required
temperature is reached.
CAUTION!
In the event of momentary stoppages of the engine, pay
attention to the synoptics and check for any alarm signals.
Do not restart the engine until the cause of the problem
has been removed or proper operating conditions have
been restored.
