Procedure After you have installed the positioner and put it fully into operation, you
can set the torque for the friction clutch as follows:
S
On the module cover, insert an ordinary 4 mm wide screwdriver into
a slot on the yellow wheel.
S
Now use the screwdriver to move the yellow wheel to the left, until
you can feel that it clicks in. This increases the torque of the friction
clutch.
S
You can recognize a locked friction clutch by an approx. 1 mm wide
gap between the yellow and black wheels.
S
If you have to set the zero pint e.g. after exchanging the actuator,
first reduce the torque by turning the yellow wheel to the right until
you hit the stop. After setting the zero point, you can refix the friction
clutch as described above.
Starting from the neutral setting (as delivered), you can lock the trans-
mission ratio selector as follows:
S
Adjust the yellow wheel underneath the terminals with an ordinary
4 mm wide screwdriver to correspond to the setting that you would
like (33
_
or 90
_
), turning to the left or right, until you can feel that it
clicks in.
S
Please note that you can only adjust the transmission ratio selector
after releasing the fixing.
For this reason you first have to put the yellow ring into the neutral
position, if you have to adjust the transmission ratio selector
e.g. after exchanging the actuator).
