This surveys the functioning of the close-coupled pump and stops it if there are anomalies in the parts controlled
by probes.
It has been designed to be installed in cavities in dashboards, electric panels, etc.
NOTICES
Warning:
adhere closely to the following advice
- Always install under other equipment which produces or spreads heat.
- Always follow the Circuit Diagram on pages 6-7 when making connections.
- Check that the line loading and the consumption of the connected equipment are compatible with the
technical characteristics on page 12.
- All technical interventions must be performed with the engine stationary and terminal 50 of the
starter motor disconnected.
- Never use a battery charger for the emergency start-up, this could damage the equipment.
- To protect the safety of persons and the equipment, before connecting an external battery charger,
disconnect the electrical plant terminals from the battery poles.
NOTE: THE HOLE IN THE CASING USED TO INSTALL THE PROTECTION DEVICE COULD INFLUENCE THE
LEVEL OF PROTECTION OF BOTH. STEPS MUST BE TAKEN TO MAINTAIN THE ORIGINAL LEVEL
OF PROTECTION.
THIS DEVICE IS NOT SUITABLE FOR OPERATING IN THE FOLLOWING CONDITIONS:
- Where the environmental temperature is outside the limits indicated in the .
- Where there are high levels or heat from radiation caused by the sun, ovens or the like.
- Where there is the risk of fire or explosions.
- Where the device can receive strong vibrations or knocks.
Technical Data on page 12
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.
CONDUCTION AND MAINTENANCE
ELECTROMAGNETIC COMPATIBILITY
This protection device functions correctly only if inserted in plants which conform with the CE marking standards;
it meets the exemption requirements of the standard EN50082-1 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.
YOUR ELECTRICAL TECHNICIAN CAN ASK US ANYTHING ABOUT THIS PROTECTION
DEVICE BY TELEPHONING ONE OF OUR TECHNICIANS
UNLESS WE MAKE A WRITTEN DECLARATION STATING THE CONTRARY, THIS PROTECTION DEVICE IS
NOT SUITABLE FOR USE AS A CRITICAL COMPONENT IN EQUIPMENT OR PLANTS RESPONSIBLE FOR
KEEPING PERSONS OR OTHER LIVING BEINGS ALIVE

These are on when the key is turned to "AUT". They switch off when the engine is running and the
oil pressure and battery recharger are regular.
- OIL AND BATTERY INDICATORS
- ANOMALY INDICATORS
These are enabled after the ENGINE PROTECTIONS ACTIVE indicator switches on, and they
switch on when the relevant anomaly is detected.
The engine protections are enabled when the ENGINE PROTECTIONS ACTIVE indicator is
on (20 seconds after turning the key to "AUT" or, in any case 20 seconds after the end of the start
impulse).
The interventions of the protection probes (mounted on the engine), shown by the relevant visual
indicators, stop the engine and can be divided into two groups:
After a 3-second delay for:Immediately for:
- OIL PRESSURE SWITCH
- OVERHEATING THERMOSTAT
- COOLING LIQUID LEVEL PROBE

STOPPING THE CLOSE-COUPLED PUMP
TIMER (TO BE MOUNTED EXTERNALLY)
MAIN ALARM
This is obtained in three ways:
y turning the ignition key to zero
ecause of protections intervention
ecause of timer intervention.
The protection device uses two different types of stoppage:
- activating the ELECTROMAGNET which pulled the STOP lever for 20 seconds
- disconnecting the supply to the SOLENOID which closes the gasoline passage.
-b
-b
-b
This can be obtained by mounting a visual and/or acoustic indicator externally connected to the
relevant output.
This is continuously activated if the protections or fuel reserve alarm intervene.
RESET: This is obtained by turning the ignition key to zero.
The pump protection is enabled (after 3 minutes (adjustable), the time needed for the water to be
pressurized) when the PUMP PROTECTION ACTIVE lights up.
When the pressure is regular, the relevant indicator lights up.
The intervention of the protection (5 seconds after the lowering of the pressure as detected by the
water pump pressure switch) stops the engine. This is memorized and is shown by the
INSUFFICIENT WATER PUMP PRESSURE visual indicator.
RESET: This is obtained by turning the ignition key to zero.
Connect the timer to the relevant terminal, if the working time of the close-coupled pump is to be set.
Stopping occurs after this time period and the relevant indicator lights up.
Enabled when the key is turned to "AUT", without stopping the engine.
