6.3 Setting a different travel
Please make sure not to damage the adjusting lever [260] when manually extending the spindle!
If the travel has to be adjusted, the adjustment must be made in the end position "connecting rod extended".
Adjusting lever
[260]
and driving lever
[259]
must be exactly in parallel in their tilted position.
● Use an open-end wrench with width across flats 10 to loosen the flat nut
[278]
on the slider
[261]
● Move the slider
[261]
and use the marks on the adjusting lever to set the desired travel; retighten the flat
nut
[278]
The travel of the actuator type E66 is continuously adjustable from 16–80 mm. It is therefore possible to set any
desired intermediate position (travel marks at 16 – 20 – 25 – 30 – 35 – 40 – 50 – 60 – 70 – 75 – 80 mm).
6.4 Setting the potentiometer
● Use the handwheel to move the actuator to the end position "connecting rod extended" until DE switch S1
is switched. Make sure the adjusting lever
[260]
(see figure 8) and driving lever
[259]
are parallel in their
tilted position
● Use a screwdriver to move the potentiometers' slider to its end position by turning the potentiometer shaft
on the rear of the potentiometer counter-clockwise until a stop is felt
● Move the actuator through the adjusted travel range to the end position "connecting rod retracted". The
potentiometers will rotate to the other end position
● Use a measuring instrument (ohmmeter) to monitor the potentiometer movement and check whether the
potentiometer is moved through its entire rotation angle
When reaching the end position, the potentiometers must not reach their stops as this would activate the sliding
clutch between the potentiometer pinion and the potentiometer shaft. A reproducibility of the results is then no
longer ensured.
• In this case, adjust a larger travel using the slider
[261]
in the adjusting lever
[260]
(refer to chapter 6.3)
