or sensor-cam when
necessary
The cover-switch is a two-
way switch. Or pin 1 and
2 or pin 2 and 3 are
closed.
Malfunction of the switch
might also result in the
following error:
“E068 CR Encoder Error”
Sensor state:
Pin 1 and 2 on the sensor
are closed, Pin 3 is open

!Attention!
Be careful when
adjusting the sensor-
bracket, the sensor-lip is
not fully stressed. This
will decrease life and
possibly damage the
sensor!
Adjust the sensor and
make sure there is a 0,5
to 1mm gap as
illustrated.
