The electronic device EP 5 (M5) ensures the protection
of the engine in case of:
- low oil pressure
- engine high temperature
- battery charge
- fuel stock
- overspeed
Located on the front panel of the machine, the EP 5
device enters in operation turning on the ignition key b) -
device inserted - and will signal it is working through the
warning light M5.6 .
The feeding is visualized by winking light and the activation
by fixed light.
In the lapse of time between the two lights (winking and
fixed) , the device will carry out a "self control" cycle.
To start the machine, bring the ignition key to position c)
(starting).
IGNITION KEY
The ignition key has three operation positions:
a) device not inserted (OFF)
b) device inserted
c) starting with automatic return
STOP BUTTON
It allows to stop the engine in any condition.
Push the button until the engine stops.
OVERSPEED (M5.3)
It signals the intervention of the overspeed device
connected to the alternator frequency at 50 as well as at
60 Hz .
The optical and acoustic signal is activated, and the
engine stopped.
HIGH TEMPERATURE (M5.4)
It signals, through the temperature sensors, a high tem-
perature anomaly.
The optical and acoustic signal is activated, and the
engine stopped.
Check: the air duct (there must be no obstruction), the
cooling liquid (if engine is water-cooled), the oil level,
etc....
LOW OIL PRESSURE (M5.5)
It signals, through the pressure sensors, a low oil pressure
anomaly.
The optical and acoustic signal is activated, and the
engine stopped.
Check the oil level and, if it is correct, call the Assistance
Service.
FUEL STOCK (M5.1)
It signals the fuel state, inside the tank, running out,
acoustically with the siren and optically, without stopping
the engine (the signal lasts until the cause
USE OF THE PROTECTION
is eliminated).
EP5 ENGINE PROTECTION
BATTERY CHARGE (M5.2)
It signals the failed exicitation of the battery charge
generator and therefore the battery recharging.
The visual signal will last without stopping the engine,
until the cause is eliminated.
FEEDING (M5.6)
The signal point out that the device is working.
N.B.: if the unit is used in hot climates and whit loads
near to the maximum, the protection can be triggered
off, please reduce the load of the engine.
In case of intervention of the device, after having removed
the cause of the problem, it is sufficient to bring back the
ignition key to the position "OFF - device not inserted",
them start again the new work cycle.
!
THE ENGINE PROTECTIONS OF THE "EP" TYPE
DO NOT WORK WHEN OIL IS OF LOW QUALITY
BECAUSE NOT CHANGED REGULARLY AT
INTERVALS AS PRESCRIBED IN THE OWNER'S
ENGINE MANUAL.
