The "collision protection" equipment serves the collision and object protection
to avoid damage to property - no personal protection!
At the pressure wave sensor, up to two control units can be connected. If the
control strip is compromised, the pressure wave sensor will be triggered.
The control unit stops the lifting movement and moves 25 mm back. The display
indicates error "F21".
The control continuously queries the existence of a pressure wave sensor.
A sensor is expected from the first detection.
If the sensor is no longer detected, the control unit will stop the lifting movement
and notify error "F20".
See section "Troubleshooting".
