Safety information
Note
A set of laser warnings in German/US English and French/US English is included in the de-
livery scope. The GB English/US English warnings can be pasted over with these if neces-
sary.
If the CLX is installed in a machine/panel with the result that the laser warning labels
are no longer visible, additional warnings in the same language (not included in the
scope of delivery) must be provided on the machine beside the emergence aperture
of the laser beam.
Internal protective circuits
The CLX is equipped with monitoring circuits that deactivate the laser diode in the event of
a malfunction.
Activation and deactivation of the laser diode is controlled by the reading pulse trigger.
A timer (laser timeout) automatically deactivates the laser diode in Reading mode ("Sensor
input" and "Serial interface" trigger mode) if the reading interval has not ended after
10 minutes (default setting). However, it does not end the reading interval. In this case, the
CLX outputs the message
"Laser safety timeout"
on the auxiliary interface. The reading interval must be terminated by resetting the trigger
signal. The laser diode is activated again by the next reading trigger.
The laser timeout can be set in the range of 1 min to 25 h or deactivated
In the "Percentage Evaluation" mode as well as in the pulse mode "Free-running", in
reading mode, the laser diode is constantly activated. In the pulse mode "Object Pol-
ling" the laser diode is activated due to the parameterized search/pause ratio.
Note
In Reading mode, the CLX carries out a measurement referencing at regular intervals. During
referencing, it turns the laser diode on for a maximum of 10 seconds.
