7.8 Motor safety measures
The control of the electrical motor is equipped with an overload protection, which is
autonomously switched off in case of overload. The motor will only be operational
again after a short waiting time. The cooling-off time of the motor can be up to 18
minutes depending on the ambient temperature.
NOTE:
Opening the motor will result in expiration of the warranty.
The intermittent operation of the motor is not a defect, but is
only for your own safety.
7.9 Impact and jamming protection (hoist motor)
The electrical motor (hoist motor) features an integrated impact and jamming
protection (free wheeling). This feature avoids jamming, pinching and/or crushing
dangers when the spreader bar of the NORA standing and raising aid strikes or
encounters an obstacle. The motor runs free until the obstacle is removed or the
NORA standing and raising aid is removed from the obstacle.
After the obstacle has been removed, the spreader bar could start lowering
autonomously. Therefore, you must immediately release the button of the handset as
soon as you have noticed that an obstacle has been encountered.
