Installation
In order to drill holes on the area where the panel is to be
mounted, refer to the dimensions indicated in Chapter 18.
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.
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 warning lights are commanded by a specific alarm timing
and recording electronic circuit. The circuit is programmed so
that when it is powered all the warning lights switch on and
the horn produces an acoustic signal.
During the starting phase and for the subsequent 4 sec-
onds, needed to stabilize the low oil pressure signal, all the
module's functions are inhibited (apart from the engine
over-speed stopping function); 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.
The identification of the engine out of rotation condition
and the consequent activation of the relating warning light
is carried out by the J16F over speed control module (on
request). The alarm managing module is also equipped with
the circuit which controls the contactor which causes the
engine to stop through an electro-valve situated on the
injection pump.
