In order to determine bearing position P in the roller shutter box, measure and
calculate the following dimensions:
D
Diameter of the rolled up roller shutter
X
D/2
Distance between the bearing position P and the
centre of the guide rail (3)
Y
>X
Distance between the bearing position P and the
bottom of the roller shutter box. So that the roller
shutter has sufficient clearance, Y must be greater
than X.
ATTENTION
Damage to the tubular motor due to the roller shutter being rolled
up slanted.
➢ Make sure that the device is installed horizontally.
➢ Using a pencil, mark the bearing positions P on the right and left inner sides of
the roller shutter box.
➢ Make sure that the marks are aligned horizontally.
➢ Hold the bearings centrally on the marks.
➢ Mark the holes to be drilled using a pencil.
➢ Drill the holes using an 8 mm drill bit.
➢ Insert the plugs.
➢ Screw the bearings down tightly.
Sawing the winding shaft to length
In order to determine the length L of the winding shaft, measure and calculate the
following dimensions:
A
Clear width of the roller shutter box
B
b1+b2+b3
b1
Depth of the counter bearing
b2
Width of the roller capsule limit stop
b3
1/3 of the roller capsule shaft length
C
c1+c2+c3
c1
Depth of the adapter limit stop
c2
Depth of the driving head
c3
Depth of the drive bearing
L
A-(B+C)
➢ Using a pencil, mark the length L on the winding shaft.
➢ Saw the winding shaft to length at a right angle using a metal cutting saw.
➢ Deburr the inner and outer edges using a file.
Assembling the device
➢ Slide the adapter (1) with the groove over the limit ring (2) spring on the driving
head (3).
➢ 1. Slide the driver (1) up to the limit stop onto the tubular motor's axle pin (2).
➢ 2. Secure the driver with the enclosed securing clip (3).
