Figure 6.9: Arrangement of the muting sensor for timing controlled 2-sensor muting in an exit application
The two muting signals must be activated simultaneously within 4 s and the PLC signal must be indepen-
dent of the Light Beam Device signal. An additional arrangement (see figure 6.9) utilizes light scanners
which are arranged and set so that the scanning area of one of the two sensors does not extend out of the
danger zone. This assumes that the transport material no longer stops when MS1 is exited.
6.3 Mounting the safety sensor
Proceed as follows:
• Select the type of fastening, e.g. sliding blocks (see chapter 6.3.3).
• Have a suitable tool at hand and mount the safety sensor in accordance with the notices regarding
the mounting locations (see chapter 6.3.1).
• If possible, affix safety notice stickers on the mounted safety sensor or Device Column (included in
delivery contents).
After mounting, you can electrically connect (see chapter 7), start up, align (see chapter 8 „Starting up the
device“), and test (see chapter 9.1) the safety sensor.

The installation height of the muting sensor is not significant here, since manipulation within the
danger zone can be ruled out.
The muting function remains active up to 4 s after MS1 becomes free. This arrangement is also
impossible to manipulate with Safety Light Curtains up to a resolution of 40 mm from outside of
the danger zone, as the protective field is interrupted before MS1 is reached.

Check: Yes No
Do the protective field height and dimensions satisfy the requirements of EN 13855?
Is the safety distance to the point of operation maintained (see chapter 6.1.1)?
Is the minimum distance to reflective surfaces maintained (see chapter 6.1.4)?
