Setting instructions:
Venetian blind drives are supplied from the factory already set to the
lower end position. Connect installation cable to venetian blind drive.
Setting the upper end position:
• Move venetian blind upwards with the
corresponding push button.
• Press in the orange adjustment button while it
is moving up and hold it in for
at least 5 seconds
(adjustment button stays latched in).
Advice:
This must have taken place at latest 0.5 m before reaching the
end position. After pressing the adjustment button it must stay
latched in.
• With the help of the installation cable
travel directly to the upper end position
(fine adjustment by means of inching
operation with the installation cable).
• By changing the direction of travel the
adjustment button is automatically
unlatched and the upper end position
is then set.
Installation in headpiece
Installation instructions:
• Install drive without restraint,
in correct
position (safety cut-out showing
downwards)
, and properly aligned with
the shafts in the venetian blind head.
• Impacts (e.g. hammer blows) are not
permitted on drive, shaft or coupling.
• The axle height of the drive is 27.5 mm.
See JA accessories for dampers for different
bearing blocks axle heights.
• Make sure that the shaft is not radially loaded.
• Make electrical connection with installation cable and
check the turning direction of the drive shaft according
to the direction advice on the front of the limit switch
housing. Travel to the lower end position again with the
DOWN
pushbutton.
• Couple drive to shaft.
Advice:
• Valid only with right hand installation.
• In the case of left hand installation the colour assigment is exactly
reversed.
After the venetian blind motor has been installed, attach these
instructions to the cable for the use of the electrician.
Advice:
The drive may only be operated with an safety cut-out.
Mounting instructions
Mounting of the safety cut-out „right hand installation“
Remove label on the bottom side of the limit switch housing and
insert the safety cut-out with
orange
or
black
cap in the openings
and engage it in such a way that the orange or black pressure pin
points towards the side of the orange adjustment push-button
UP
.
If the supplied safety cut-out cannot be used, e.g. due to lack of
space, then the label must not be removed since it protects the
inside of the limit switch against dirt.
Please check the function of the safety cut-out. Incorrect
installation may lead to damage.
If the safety cut-out is not long enough,
it can be extended by 10 mm at a time
with the safety cut-out extension
(article number 16 101.4501).
(Maximum of 3 safety cut-out
extensions can be plugged on).
Insert the blade of a small flat
screwdriver into one of the grooves
on the orange cover and by pressing the blade towards the middle
of the safety cut-out, lever off the cover. Clip on the extension and
then clip on the cover again.
Mounting of the safety cut-out „left hand installation“
(special Accessory)
When installing the JA drive as a left-hand system
the arrangement of the microswitches inside the
limit switch housing automatically swaps over the
UP
and
DOWN
movments.
This means that the safety cut-out with the white
cap (article number 26 200.1101) must be used.
This safety cut-out must be inserted and clipped
into the openings of the limit switch housing so
that the „white“ pressure pin points to the side of
the „white“ adjustment push button. The label L provided with the
directional advice, should then be stuck over the existing label on
the front.
Mounting of the QuickSnap coupling for JA
1. Apply coupling at an angle whilst observing the position of the
coupling with respect to the shaft: The stop spring should slide
on the upper surface of the hexagonal shaft.
2. Push coupling a little further until the spring audibly latches
into the groove. (Click).
3. If the groove is covered by a bearing or lockwasher, the
hexagonal shaft can be correspondingly pushed back until the
coupling spring latches into place.
4. By pulling it by jerks check that the coupling is securely seated.
Dismantling of the QuickSnap coupling for JA
Do not forcibly remove the coupling.
1. Lift up the motor coupling retaining spring on the shaft with a
small screwdriver.
2. Pull off the coupling.

Setting the lower end position:
It is not normally necessary to set the lower end position since the
ventian blind drives are set to the lower end position in the factory.
If it is necessary however the setting takes place in the same way as
for the upper end position.
• Move venetian blind downwards with the corresponding push
button.
• Simultaneously press the white adjustment button and hold it
down for
at least 5 seconds
.
Advice:
This must have taken place at latest 0.5 m before reaching the end
position. After pressing the adjustment button it must stay latched in.
• With the help of the installation cable travel directly to the lower
end position (fine adjustment by means of inching operation
with the installation cable).
• By changing the direction of travel the adjustment button is
automatically unlatched and the lower end position is then set.
Readjustments:
If the respective end position is not accurately set or if the end
positions have changed due to changed winding behaviour of the
venetian blind, then the end positions will have to be reset as
described above.
With the help of the installation cable the venetian blind should be
moved back to about 0.5 m before the desired end position.
The limit switch range is 85 revolutions of the shaft.
