RECOGNISING ALARMS
Indicator and alarm synoptics
The IVECO MOTORS instrument panel contains the indicator lights
used to indicate the state of operation of the engine. Light-up of
these indicators is piloted by electronic circuits, which have a
simultaneous alarm timer and storage function.
7A. Maximum allowed rotation speed exceeded (on request) - 7B.
Air filter blocked - 7C. Fuel level low - 7D. Coolant temperature
high - 7E. Oil pressure low - 7F. Alternator malfunction - 7G. Engine
coolant level low - 7H. Pre-post heating.
Some types of engine and relevant equipment only make some of
the functions indicated in the key available.
If the machine Manufacturer uses different technical options there
may also be further changes to the above.
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.

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.
