14 Help in the event of malfunctions
Cause: Although one of the remote control's outputs is actuated, the
power mast does not move - the mast is stuck or blocked;
Control outputs: The outputs are locked in automatic mode;
Remedy: Check whether an obstacle is located in the mast's path, the
mast is possibly bent or the mast's moving mechanism is severely
soiled and therefore blocked;
Specifically when working with the laser receiver:
Reflection errors (e.g. due to reflective surfaces or flashing lights on the
construction site) are the most frequent malfunctions when working with
laser systems.
As a result of this, the laser receiver evaluates the signals sent by the
laser transmitter, evaluates them and indicates error situations using its
LED display as follows:
Cause: No laser beam hits the laser receiver;
Control outputs: The outputs are locked in automatic mode;
Remedy: Realign the laser receiver to the laser beam;
Cause: The laser receiver is acyclically hit by laser beams or is hit
simultaneously by several laser pulses;
Control outputs: The outputs are locked in automatic mode;
Remedy: Cover the laser transmitter apart from the actually required
circular cut-out;
Remove reflective surfaces (motor vehicle glazing, windows, etc.) from
the laser beam's area of influence or cover these surfaces;
Check whether a second laser transmitter is in operation in the vicinity;
Cause: Negative deviation from the laser transmitter's specified
minimum rotational speed (<10 Hz [revolutions per second]);
Control outputs: The outputs are locked in automatic mode;
Remedy: Increase the laser transmitter's rotational speed if it is
equipped with a speed control;
Check the laser transmitter's rechargeable battery / supply voltage;
