Function
When switch S36 is in off position (in picture), current can
affect the solenoid Y8 when the starter switch is turned to the
starting position and the engine can be started (engine does
not start, if the switch is in the on position).
When the switch S36 is turned on, current flows to the sole-
noid via relay K18. If on of sensors S13, S17, S16 or S18
becomes grounded, the relay breaks the circuit and the
engine stops. Warning lights illuminates normally (also stop ---
light flashes).
Note! Stop---light wire must be equipped with a diod. Other-
wise, when driver uses the direction indicator lever S4 or
hazard warning flashers, relay K18 becomes earthed via
bulbs E3---E6 caused engine stop. In the year ---96 a diode
has been added in the instrument, and the auxiliary diode is
not needed. These instruments with the diode can be recogni-
zed by a green dot beside the part no.
The gearbox oil pressure sensor is placed on the servo valve
block on the RH side of the gearbox and the temperature sen-
sor is placed on the front side of the valve block
Engine oil pressure sensor is placed on the RH side of the
engine and the temperature sensor on the engine beside the
thermostat housing.
Testing the function
Regarding the stop solenoid, see page 350/7. If the tractor
has Stanadyne distributor pump, the stop solenoid is as stan-
dard inside the pump, see picture on page 220/12.
The function can be tested while the engine is running and
switch S36 in the on position. When a wire connector of one
of the sensors S13, S16, S17 or S18 is connected to the tractor
frame, the warning light must come on and the engine must
stop. Stop light flashes, when engine temperature sensor
becomes earthed. Other functions have separate warning
lights.
