- MOTOR PUMP START UP
Lit up with key on “AUT”, they switch off with the engine running
and regular oil pressure and battery charge system.
The protections of the pump is enabled when the PUMP PROTECTIONS ACTIVE light after the water
pressure has remained stable for 2 consecutive minutes, indicated by the visual signal REGULAR PUMP
PRESSUR and in any case 10 minutes from starting of the engine).
Intervention of the protection (5 seconds by the lowering of WATER PRESSURE detected by the WATER
PUMP PRESSURE SWITCH to be mounted on the pump) stops the engine, is stored and is indicated
by the optical signalling INSUFFICIENT PRESSURE WATER pump. (SEE WATER PUMP PRESSURE
ADJUSTMENT, page 5) .
RESTORE: by turning the starter key onto “ZERO” (the engine pump will stop).
The push-button excludes pump protection:
- exclusion is obtained by keeping it pressed for at least 3 consecutive seconds; the function is
indicated by the two intermittent lights .
- this exclusion is cancelled by pressing the push-button again or by turning the start key onto
“ZERO”.

Interventions of the protection probes (fitted on the engine), indicated by the relevant lights, stop
the engine, they are memorised and can be split into two groups:

OPERATION
Is activated with key in AUT the display shows the phrase .
The duration of the preheating action can be set.
Is indicated on the display when the action has ceased .
The control unit shut down the engine in three conditions:
- turning the starter key onto “ZERO”.
- protection intervention.
- timer intervention at the end of the work period.
The unit adapts to two different stop system:
- by working the ELECTROMAGNET for 20 seconds which pulls the STOP lever.
- by cutting off power to the SOLENOIDVALVEshutting off the flow of fuel.

EMERGENCY STOP
Always enabled, allows if necessary the motor pump to be operated for a settable time (maximum 96 hours), at the
end of which it is stopped and on the display the end of work time indicator comes on.
The work time is set by pressing the push-button ( lights up) until the desired value appears on
the
DISPLAY .
On releasing the push-button, the timer automatically starts working, continously displaying the remaining
work time.
CANCELLING THE SET TIME
To zeroing the set time, to keep the push-button pressed until it reaches zero.
OPERATION TIMER
The emergency stop can be actived in all working conditions, by mounting one or more
click-down push-button. On the display it’s reported
EMERGENCY
STOP .
GENERAL ALARM
This can be obtained by fitting on the outside an optical and/or acoustic signaller to be
connected to its connector.
It is activated on protection intervention.
RESET: is obtained by turning the starter key back onto “ZERO”.
INSTRUMENT
The control unit comprises four instruments which can be selected in sequence by pressing the button

YOUR ELECTRICAL TECHNICIAN CAN ASK US ANYTHING ABOUT THIS CONTROL
UNIT BY TELEPHONING ONE OF OUR TECHNICIANS
Only for starting and surveillance of the diesel motor pump and stops it if there are anomalies in the parts
controlled by probes.
It has been designed to be installed also on the machine.
Warning:
adhere closely to the following advice
- Always follow the Wiring Diagram on page 5 when making connections.
- All technical interventions must be performed with the engine stationary and terminal 50 of the starter
motor disconnected.
- Check that the line loading and the consumption of the connected equipment are compatible
with the described technical characteristics described on page 2.
- Install in such a way that there is always adequate heat disposal.
- Always install under other equipment which produces or spreads heat.
- Never disconnect the battery terminals with the engine running.
- Never use a battery charger for the emergency start-up; the control unit could be damaged.
- In order to safeguard people and equipment, before connecting an external battery charger, disconnect
the electrical system terminals from the battery poles.
THIS CONTROL UNIT IS NOT SUITABLE FOR OPERATING IN THE FOLLOWING CONDITIONS:
- Where the environmental temperature is outside the limits indicated in the Technical Data.
- Where the air pressure and temperature variations are so rapid as to produce
exceptional condensation.
- Where there are high levels of pollution caused by dust, smoke, vapour, salts and
corrosive or radioactive particles.
- Where there are high levels or heat from radiation caused by the sun, ovens or the like.
- Where attacks from mould or small animals are possible.
- Where there is the risk of re or explosions.
- Where the control unit can receive strong vibrations or knocks.
ELECTROMAGNETIC COMPATIBILITY
This control unit functions correctly only if inserted in plants which conform with the CE marking standards;
it meets the exemption requirements of the standard EN61326-1 but it cannot be excluded that
malfunctions could occur in extreme cases due to particular situations.
The installer has the task of checking that the disturbance levels are within the requirements of
the standards.
CONDUCTION AND MAINTENANCE
The following maintenance operations should be performed every week:
- check that the indicators function;
- check the batteries;
- check that the conductors are tight, check the condition of the terminals.
UNLESS WE MAKE A WRITTEN DECLARATION STATING THE CONTRARY, THIS CONTROL UNIT IS
NOT SUITABLE FOR USE AS A CRITICAL COMPONENT IN EQUIPMENT OR PLANTS RESPONSIBLE
FOR KEEPING PERSONS OR OTHER LIVING BEINGS ALIVE.
