7.7 Control unit – Reset
Reset the control unit in the following cases:
• If a serious error was detected by the control unit and this has now been properly recti-
fied but the control unit has locked out the affected functions for safety reasons.
Locking can be caused, for example, by:
⁃ A fault in the handset (e.g. a short-circuit/interruption in the cable; a jammed but-
ton),
⁃ A fault in the adjustment motors (e.g. a short-circuit/interruption in the cable, or a
fault in the position detection/in the end position switch),
⁃ An internal fault in the control unit,
• If the module emits intermittent sound signals when making motorised adjustments,
and/or no adjustments are possible or adjustments are only possible on one side.
Effect:
• Deletes any existing saved errors (RESET). The last error is retained and can still be
read out/displayed.
Proceed as follows:
Press and hold both of the marked buttons simultaneously (a continuous signal sounds) until
after approximately 5 seconds an intermittent signal sounds (= RESET/manual mode)
