Height of the muting-sensor light beams
The same conditions apply as with sequence controlled 2-sensor muting see figure 6.11.
Select the height of the light beams of the muting sensors so that the transport material is detected and
not the pallet or transport device.
Otherwise, you must take additional measures to prevent people from entering the danger zone on top
of the pallet or transport device.

Mounting the safety sensor
Proceed as follows:
• Select the type of fastening, e.g. swivel mount see chapter 6.3.2 „BT-240 swivel mount (optional)“or
clamp bracket see chapter 6.3.3 „BT-P40 clamp bracket (optional)“.
• 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 „Suitable mounting locations“.
• If possible, affix safety notice stickers on the mounted safety sensor or device column.
After mounting, you can electrically connectsee chapter 7 „Electrical connection“, start up, align see
chapter 8 „Setting the device into service“, and test see chapter 9.1 „Before the initial start-up and following
modifications“the safety sensor.
