INSTALLATION
Rough- in or install conduit pipe to the connector box for the
electrical connecting line according to local building and
electrical codes.
Place the tube drive adapter (7) on the motor and fix the
A
drive adapter with the parts (3 or 4).
Fix the square pin with the screws on the motor (5 or 6).
Fully unroll the shutter (a). Remove the shutter material
B
from the tube (b). Remove the manual control (c).
C
Remove the tube.
Push the motor (1) completely into the tube. The limit
D
switch operates only if the drive unit is fully inserted.
Ensure that the adapter ring is pushed fully home. Do not
force it or strike it. Do not damage the tubular motor
by drilling!
Proceed according to the specific requirements for left-
E
sided (a) or right-sided (b) operation:
Secure the mounting bracket (8) to the wall (use suitable
F
screws and plugs).
Insert the motor (a) into the mounting bracket (8) and
G
secure it.
Make sure the set screws for the limit adjustments
are accessible.
Don't return the shutter material to the tube yet!
ELECTRICAL CONNECTION
H
Never connect more than one motor to a timer or
wall switch without using a central module – (h)
(available as an accessory), i.e. one central module
is required for each connected motor.
The illustration also shows the wall bracket on the drive side
(b), the motor (a); the steel tube (c); the end cap (d); and the
opposite wall bearing (e).
For a left-side motor installation, follow the wiring diagram
exactly as shown in the control accessory package.
For the correct direction of rotation in a right-side motor
installation, electrical wires (brown & black) must be reversed
between the control accessory and the motor. (See instructions
packed with the accessory you have chosen).
Have the electrical hook-up done by a qualified electrician
in compliance with your local electrical code.
Accessories can be found in section L on page 4.
SETTING THE LIMITS
I
Procedure for Adjusting
"Open" and "Close" Positions
(refer to figure I for lefthanded installation)
#1 Limit Setting for "Shutter Open"
+ = increase travel
– = decrease travel
#2 Limit Setting for "Shutter Close"
+ = increase travel
– = decrease travel
Please observe that the limits of the motor only
operate in a complete installation.
Read the following instructions carefully before making
any open or close limit adjustments.
To attach the shutter material on the tube, use ONLY the 3.9 x
6.5 mounting screws included (not suitable for RA10).
Otherwise, the drive might be damaged by screws which are
too long.
This instruction applies particularly to model RA10 (no
screws included). Use the appropriate fixing parts to
secure the shutter material to the tube. The drive may be
damaged by using screws which are too long.
IF ADJUSTMENTS ARE NEEDED, PROCEED AS FOLLOWS:
LIMIT ADJUSTMENT SCREW #1 - OPEN
Run the motor through an open cycle.
o If motor stops before shutter is fully opened:
Turn set screw #1 toward + and open the shutter until desired
position is reached.
o If motor stops after shutter is fully opened:
Close shutter below desired position. Turn set screw #1 toward
– and open shutter again. Repeat this step as often as
necessary to reach the desired position
LIMIT ADJUSTMENT SCREW #2 - CLOSE
Run the motor through a close cycle.
o If motor stops too soon (before shutter is fully closed):
Turn set screw #2 toward + and close shutter again, until
desired position is reached.
o If motor stops after shutter is fully closed:
Retract shutter above desired position. Turn set screw #2
toward – and close shutter again. Repeat this step as often as
necessary to reach the desired position.
