Setting the magnetic frequency genera-
tor
The magnetic frequency generator (Fig. 1) is atta-
ched to the gearbox at the height of the intermediate
wheel in relation to the speed control drive, Fig. 2. It
creates electrical impulses proportionally to the
speed of the intermediate wheel by sensing the teeth
of the gearwheel moving past the speed generator,
and passes these impulses on to the control electro-
nics.
A frequency generator (3) incorrectly set to the
intermediate wheel, as well as adhering metal
particles on the permanent magnet of the
frequency generator influence the impulse
output to the control electronics.
The frequency generator is factory set, there-
fore, only remove for an important reason.
Job:
Removal
Loosen knurled screw (1) and disconnect the
plug-in connection.
· Loosen locknut (4).
Manually remove the frequency generator (3).
Check
Check frequency generator for possibly adhering
metal particles or soiling, clean, if necessary.
Refitment
Coat frequency generator (3) and screw-in hole
with the DEUTZ DW 66 compound. Screw in the
frequency generator.
Turn the gearwheel (5) until the tip of a tooth is
positioned opposite the frequency generator.
Manually screw the frequency generator down to
the tip of a tooth.
Turn back the frequency generator 180° - 360°
(
1
/
2
- 1 revolution)
Spacing ”X” between the gearwheel (5) and frequency
generator (3) must amount to 0.5..... 1.0 mm.
The hole (2) on the frequency generator must
be positioned in or opposite the motor rota-
tional direction (6), if necessary, turn back
slightly.
Once the setting has been completed, tighten
locknuts (4) (ensure that the position of the fre-
quency generator is not changed).
· Establish the plug-in connection.
Retighten knurled nut (1).
