Obstruction detection / Blockage detection
Caution
Use of the drive’s obstacle detection system as personal protection is not permitted. It has
been designed exclusively to protect the roller shutters or sun protection system from be-
ing damaged.
If the drive is correctly installed, it switches off when it detects obstructions or shutter faults.
The following are detected both when using attachment springs and when using anti-lifting devices:
In the DOWN direction (Obstruction detection)
A curtain jam when closing due to objects on the window sill or sticking of the lateral guide tracks.
In the UP direction (Blockage detection)
Extremely large increase in the load (e.g., frozen end strip on the window sill)
To avoid overly sudden deactivation during closing, the drive only responds to an obstruction one or two revolutions after the im-
pact.
Information for the electrician
Tubular drives with electronic limit switching can be connected in parallel. The maximum switching contact load of the switching
equipment (timer, relay control, switch, etc.) must be observed. To operate drives with electronic limit switching, only use switch-
ing elements (timers) that are
not
earthed via the drive. The outputs of the switching element must be potential-free in the neutral
position.
Use external conductor L1 to control the up and down direction. Other devices or consumers (lamps, relays, etc.) must not be dir-
ectly connected to the drive connecting cables. For this purpose, the drives and additional devices must be decoupled by relay
controls.
When installing the drive, all-pole disconnection from the mains with a contact gap of at least 3 mm per pole must be provided.
Attention
Only use mechanically or electrically locked switching elements with a marked zero posi-
tion! This also applies when drives with electronic and mechanical limit switching are used
in the same system. The changeover time for switching the running direction must be at
least 0.5 s. The switch and control must not execute simultaneous UP and DOWN com-
mands. Protect the electrical connections from damp.
Once you have finished wiring everything to the control, ALWAYS check the right direction
assignment of the drive to the control buttons UP and DOWN, EXTEND and RETRACT.
If the drive is to be operated with devices which contain sources of interference, the elec-
trician must ensure suitable interference suppression for the relevant devices.
Disposal
The crossed-out bin symbol on the product indicates that the device is subject to mandatory disposal separate from household
waste. This product must be handed over to a collection point for electrical and electronic equipment at the end of its service life.
The packaging material must be disposed of properly.
Maintenance
These drives are maintenance-free.
