Limit stop switch instead of upper end position
• If the direction UP should be turned off by the limit stop switch, there is no need to program
the upper end stop. The blind moves every time against the limit stop switch.
• If an upper end position is already programmed and you now want to switch off with the limit
stop switch, the programming mode must be activated and the blind moved against the limit
stop switch. The lower end position is unchanged and the programming is completed.
• The motor is now always turned off by the limit stop switch.
Cancel the programming mode:
In order to cancel the programming mode, press the programming keys (programming key/UP/
DOWN keys/limit stop switch and DOWN key) until the motor conrms the cancellation of the
programming mode after about 3 seconds with 2 x click-clack.
12. Referencing on the limit stop switch
The referencing on the limit stop switch can compensate a possible drifting of the upper end
position due to the modied winding behaviour of the lifting tapes.
If the referencing has been activated (see below), the next UP run is done till the limit stop
switch.
The variation in distance between the upper limit position and the limit stop switch is stored.
After 5, 20 and then every 50 cycles on the upper end stop, the motor runs against the limit
stop switch in order to test if the variations in distance have changed. If this is the case, the
upper end position is readjusted.
The motor stops on the limit stop switch by the reference runs.
13. Enable/disable reference cycles
The referencing is enabled on delivery. The referencing can be enabled only if the upper end
position is set on position.
Switching on/off referencing:
Press the programming keys (programming key/UP/DOWN keys/limit stop switch and DOWN
key) between 6 and 9 seconds until the motor jerks 1 x after about 3 seconds and another time
after 6 seconds for feedback “Switching on/off referencing”.
A subsequent UP command with 1 x jerking enables the referencing, a DOWN command with
2 x jerking disables it.
14. Resetting to factory settings
Press the programming keys (programming key/UP/DOWN keys/limit stop switch and DOWN
key) about 10 seconds until the motor jerks 1 x after 3 seconds, 1 x after 6 seconds and 4 x
after 10 seconds. Then the motor is reset to factory settings and the referencing is activated.
15. Obstacle detection and anti-freeze protection
For an optimal operation of the obstacle detection function, move the blind from bottom to top
without interruption, after the programming has been completed.
After an obstacle detection (e.g. obstacle or blind frozen to the window sill), the UP direction is
blocked.
A short command in the DOWN direction releases the UP direction.
