Operating instructions
5
All R8/17C PRF+ to R40/17C PRF+ tubular drives are intended solely for the operation of roller shutters. The tubular drive is t-
ted with springs which support both the shutter suspension and mechanical anti-lifting devices (e.g. Zuruh-Feller, Simu, GAH
Alberts or Deprat). These are detected automatically.
The mains connection cable is not suitable for supporting the weight of the drive. Always support the drive with the housing tube.
Other applications, utilisation and modications are not permitted in order to protect the safety of the users and others, since
these actions can impair the system’s safety, resulting in personal injuries and property damage. Becker-Antriebe shall not
accept liability for damages arising from such actions. Always observe the information in these instructions when operating or
repairing the system. Becker-Antriebe shall not accept liability for damages resulting from incorrect usage.
Attention
Anti-lifting devices may only be used if sufciently rigid roller shutter laths are used. When closed, the shut-
ters must not extend over the guide rails, as this may put too great a load on the joint between the top two
slats, which could consequently be damaged.
Before reaching the lower end limit, the roller shutters must have made at least 1.5 revolutions. This is normally the case when
the window height is ve times the effective tube diameter.
Example:
60-series octagonal tube with anti-lifting device from Zuruh-Feller:
Effective tube diameter: 9 cm -> min. window height > 45 cm
Assembly of the Becker connecting cable (Fig. 1)
Ensure the Becker connecting cable is de-energised before proceeding. Insert
the cable into the drive head until the location lug audibly engages behind the
self-locking clip. If necessary, use a suitable at-bladed screwdriver to insert
the cable correctly. This is done by inserting the screwdriver into one of the two
recesses in the connector.
Check the locking.
Disassembly of the Becker connecting cable (Fig. 1)
Caution
Always completely de-energise the Becker connecting cable
prior to disassembly.
1. Carefully insert a suitable at-bladed screwdriver into the recess of the self-
locking clip until it releases the location lug of the connecting cable.
2. It is now possible to carefully withdraw the Becker connecting cable along
with the at-bladed screwdriver.
