6. Connect the wires of the tubular drive to those of the same colour in the programming handset and switch the power supply
on (Fig. 9).
7. Position the barrel so that the roller shutter can be attached with springs or fit the locking strap security devices in accord-
ance with the manufacturer's instructions.
Note
We recommend at least three springs per metre of barrel. When using drives with electronic limit switching it
is not possible to attach the shutter with belts. When mounting the roller shutter drive always ensure that the
motor connection cable cannot be damaged when operating the system.
Cover any sharp edges, over which the cable is led, with appropriate protective tape. In accordance with valid
VDE regulations, PVC connection cables (H05VV-F) must be led in a protective sheath when laid in the open.
If the mains connection cable is damaged, it may only be replaced by the manufacturer. Lay the cable up to the
motor, or form a loop with the cable, so that rain can run off at the bottom point.

The length of the roller shutter must not exceed the height of the window plus the clear height of the shutter box. When using
L
locking straps the closed shutter must not project beyond the guide rails or else there will be a risk of the joint between the two
I
top laths being subjected to excessive strain. Locking straps may only be used if the height of the window is not less than 5
times the largest barrel diameter (example: octagonal barrel 60 with Zurfluh-Feller locking straps: largest diameter 9 cm
S
height of window > 45 cm). The roller shutter must be prevented from being drawn into the shutter box with mechanical stop or
an angled end strip. With front-mounted units we recommend using concealed stops in the guide rails. Also prevent the indi-
H
vidual laths from slipping to the side.

5. Secure the drive according to the type of wall bracket with a spring con-
nector or a split-pin. The roller shutter can be put into operation either with
the BECKER switch fitting (Item no. 4901 002 181 0, where the drive can-
not be reset) or with the BECKER programming handset for drives with
electronic limit switching (Item no. 4935 200 011 0).
Attention
The programming handset is not suitable for continuous opera-
tion, but is only provided for commissioning!

Setting the End Limits

BECKER tubular drives with electronic limit switching automatically detect
the top and bottom end limits during an installation trial.
Attention
The obstruction detection feature is only activated when instal-
lation has been completed!
When setting the end limits ensure that the roller shutter moves
up and down smoothly.
1. First of all move the shutter to the top end limit until the tubular drive
switches off automatically. To ensure that the top end limit is detected
reliably the tubular drive pulls the shutter once with a slightly higher force
against the stop. For this reason the stop (cover, lintel) should be as firm
as possible (Fig. 10).
2. Finally run the shutter down until the tubular drive switches off automati-
cally. Make sure it runs smoothly up to the planned deactivation point. If
the final bottom end limit has not been completed yet, the deactivation
point at the end of the guide rail must be secured by placing an object
underneath temporarily (Fig. 11).
Installation is now complete.
The electronic limit switching system has stored the height of the window and
the end limits. The obstruction detection feature is switched on. The program-
ming button on the handset must not be pressed any more.
As a final check, run the roller shutter in both directions up to the end limits
again. The shutter must run smoothly and evenly.
