Note! On 8950Hi models the foremost sensor is placed
in front of the DPS and the sensor is adjusted so that the
distance between the sensor end and the impulse sleeve is
0,7 ---0.9 mm (not at a notch).
Note! Versions 1.0 and 1.1: The ETB---light indicates by
flashing, if the sensor signals are not OK (e.g. there is no
signal from one sensor), ETB---light is flashing in time 0,5
sec on and 0,5 sec off. This flashing indicates, that the sen-
sor is faulty or there are poor contacts in the connectors/
wires. Also wrong adjustment can cause malfunctions.
IMPORTANT! Versions 2.0 and 3.0: If the engine speed
sensor is damaged, the ETB---light flashes in above men-
tioned time twice, after which there is a pause of 1,5 sec. If
the PTO sensor is faulty, the ETB---light flashes three times,
after which there is a pause of 1,5 sec.
A, C and D
In connection with sensor
replacement, screw a new
sensor into the sleeve to the
same depth as was the
earlier sensor. Use Loctite
572 when fitting the sensor.
Turn the sleeve 2, until the
sensor touches the measur-
ing wheel (not at the notch)
3---7 mm
and then open the sleeve
1/2 ---2/3 of a turn. Lock the
sensor with nut 1 (sleeve
thread M18x1,5).
