General information

Each single step of the opening closing process is only executed on condition that the preceding step was performed correctly. If a single step is not confirmed within a given time, the actuation of the drive motor is interrupted. At the beginning of a process, the limit switch or potentiometer values have a particular configuration, which is examined by the control module. The control module monitors itself and the connected components. The results are read out via the diagnostic interface.
