Function of the shutter length compensation system
The shutter length compensation system is active subsequent to every
automatic learning process for the upper end point. Afterwards, the
tubular motor no longer runs fully against the upper end point in order
to protect the roller shutters and the end points.
For example, seized roller shutters can cause the automatically learned
end points and runs to be changed over a period of time. In order to
compensate for this, the tubular motor periodically runs automatically
to the upper and lower end points (the cycle for this is configured at
the factory).
i
Function of radio code
You can control the radio tubular motor directly using the radio code in order, for example,
to be also able to subsequently connect further DuoFern devices to the radio tubular
motor after installation.
Once the connection has been successfully established, you can carry out actions such as
setting the limit stops for a radio tubular motor.
The radio code can be found on the enclosed label:
Example:
NOTE
◆ The roller shutter compensation system operates automatically during normal
operation, so that generally you will not notice it.
◆ If the upper end point is manually configured, then the roller shutter compensation
system is inactive.
NOTE
Time window for activation via the radio code.
After switching on the power supply, the radio code is active for a maximum 2 hours. Once this time has
elapsed, activation using the radio code is no longer possible. Briefly disconnect the environmental sensor from
the mains to reactivate the time window.
