6.12 Damper motor 3-Stage
The damper motor rotates the damper between three
preset positions. These positions are controlled at the
motor by micro-switches, the switching positions of
which are set using the coloured cams. There is also
a black cam, which controls the activation of solenoid
valve 2 and a green one which controls the activation of
solenoid valve 3.
If the air flow requires adjustment:
Remove the cover from the damper motor and change
the positions of the cams by turning them with the aid
of the tool supplied. To deactivate a cam while you are
turning it we recommend that you switch to a different
stage and then switch back after adjustment is complete
in order to check the result.
Stage 1
Adjust the operating switch to Stage 2 (II)..
* Reduce the air volume: Turn blue cam towards 0°.
* Increase the air volume: Turn blue cam towards 90°.
Adjust the operating switch back to Stage 1 and check.
Stage 2
Adjust the operating switch to Stage 1 (I).
* Reduce the air volume: Turn orange cam towards 0°.
* Increase the air volume: Turn orange cam towards 90°.
If the orange cam is moved, change the black cam as
much. Adjust the opera-ting switch back to Stage 2 and
ensure that the correct air volume has been obtained.
Stage 3
Adjust the operating switch to Stage 2 (II).
* Reduce the air volume: Turn red cam towards 0°.
* Increase the air volume: Turn red cam towards 90°.
If the red cam is moved, change the green cam as
much. Adjust the operating switch to Stage 3 (III) and
ensure that the correct air volume has been obtained.
