Installation
In order to drill holes on the area where the panel is to be
mounted, refer to the dimensions indicated in Chapter 11.
Operation of the panel
After completing the electrical connections and engine
preparation, perform the tests required for the first start, as
described in Chapter 23.
Verify the proper operation of the panel, proceeding as fol-
lows:
o Turn the key switch on the first position, check the
tools to be powered and the Alarm and Signal Module
to perform the 5 seconds alarm test according to the
following procedure.
o Once the test is complete, only the indications prescribed
for the engine not running must remain lighted: e.g.
"alternator charge" and "low oil pressure"; the analog
instruments must provide values consistent with the
relevant physical parameters.
Testing the engine start function
Turn the key switch to the second position and keep it in it
until the engine has started, then release the switch, which
will stably return to the first position; after releasing the key,
the switch may be brought back to the starting position only
after the switch is returned to the resting or zero position.
Checking indications
After starting the engine, verify whether the operating
modes of the indications and alarms module are similar to
those set out below.
Using appropriate measuring instruments, verify the
consistency of the indications provided by the analog
instruments.
NOTE
Do not disconnect the connector 14 (see Figure 17) to
avoid wrong fuel filter clogging alarm indication.
Verify the indication of the panel revolution counter,
comparing it with the one measured by a reference
instrument; if the indication is different, proceed as described
below.
Testing the engine stop function
Stop the engine by pressing the red button on the IVECO
MOTORS panel. On customized panels press the similar
button.
Should the engine be equipped with a de-energizing stopping
device (upon request), stop it turning the key switch in the
rest position.

The indications and alarms module comprises the indicator
lights and the electronic alarm interface, timing and stor-
age circuit. It is programmed in such a way that when it is
powered, all indicator lights are lighted, with the exception
of those for "pre-lubrication", "pre-post heating" and "EDC"
failure and a sound signal is emitted by the buzzer.
The sound alarm may be silenced before the end of the
test, acting on the appropriate control.
During the starting phase and for the subsequent 15 sec-
onds, needed to stabilize the low oil pressure signal, all the
module's functions are inhibited; once this time interval
has elapsed, every alarm state detected by the sensors will
cause the associated indicator to be lighted and the buzzer
to be powered.
When a new alarm state is detected, the indicator light will
flash to highlight the occurrence with respect to any others
which may be ongoing at the time. When the sound alarm
is shut off, the light indicator will remain lighted and the
alarm will be stored until the engine is stopped.
Pre-post heating (SCP) -
13.* EDC malfunction (EDC).
