Installation
Fig.5-8.Makesurethattheoutermost
cog of the contact cam unit engages in
the gearwheel of the intermediate gear
(1). In addition, the adjustment gears
(18) must engage properly in the corre-
sponding gears of the contact cam unit
(21).
9. Secure the contact cam unit (21) and in-
termediate gear (1) with the serrated
ring(3);pushdowntheserratedringas
far as it will go.
10.Position the terminal board (17) at the
baseofthesupportata45°angle(ap-
prox.) with the switches pointing towards
the gears. Swivel the upper end of the
terminal board towards the gears until
the board is in a vertical position and
properly engaged in the support.
11. Slide the actuator board (12) back into
its guiding. Make sure that all the gears
are properly engaged. Fasten the board
using screws.
12. Adjust limit contacts as described in the
'Start-up' section.
13. Replacecover.Brieyturnthefastening
screws counterclockwise with a screw-
driver to center them. Then fasten down
the cover by tightening the screws.
Actuators without resistance transmitters
Parts from the basic unit and the retrot kit
(see Fig.5-4 and Fig.5-5) are required.
1. Unscrew screws on housing cover and
take the cover off the actuator.
2. Move the actuator stem to the end posi-
tion "actuator stem extended" or "actua-
tor stem retracted” (see the 'Operation'
section).
3. Unscrew fastening screws. Slide the actu-
ator board (12) from its guiding to the
right. Slightly lift the board and continue
pushing it further towards the cable en-
try.
4. Clip the spindle gear (2) onto the sleeve
(13). Make sure the side latch is properly
engaged in the groove of the sleeve.
5. Slide the intermediate gear (1) onto the
spindle 1 (11.1), mount the serrated ring
(3) and push it down as far as it will go.
6. Slide adjustment gears (18) onto their
spindles and fasten with one screw each.
Check whether the adjustment gears can
be turned easily. If not, slightly loosen its
screw again.
7. Align the contact cam unit (21): To do
this, turn both contact cams (19) on the
camholder(20)asillustratedinFig.5-7
corresponding with the position of the
actuator stem.
8. Slide the contact cam unit (21) onto the
spindle corresponding with the position
of the actuator stem as illustrated in
