NOTE
Ensure that the control elements cannot be reached from inside the
blocked danger zone.
—
Install the controller cabinet and the signal tower outside the danger
zone (see drawing).
Activating the light barrier
The AUTO operating mode is required for operation of the light barrier.
The white lamp must not light up. It it is on, the MAN or 0 operating
mode is active.
– Set the AUTO operating mode.
The light barrier is activated by means of the key-operated switch lo-
cated on the signal tower.
NOTE
Do not leave the signal tower unattended while the key is inserted in
order prevent the light barrier from being deactivated by unauthorized
persons during the execution of the measurement run.
—
Withdraw the key and keep it with you.
Intensity check
When activating the light barrier, an automatic intensity check is carried
out. If the beam path between the emitter and the detector is not inter-
rupted, the green lamp on the signal tower for the light barrier is on.
You can then switch the CMM drives on.
If the LED does not light up, determine the reasons for that.
Possible causes :
– Incorrect alignment of the emitter, detector or reflecting mirror.
– Dirt accumulation on the emitter, detector or reflecting mirror.
– Distance between emitter and detector is too large.
