Cleansing and adjustment of the light-barrier at belt-re-entry-zones
[7.K]
Some models (running surface 200/75cm and bigger) are equipped with light-barriers at the running belt re-entry zone
(rear position and front position for the reverse of belt rotation). As a safety measurement the light barriers effect a
quick-stop function when the light stream is interrupted by a hand, a falling towel, a coat and of course, also by dust at
the glass and/or reflector of the light barrier.
To avoid unwanted switch off (quick stop), the light barrier and the reflector glass should be cleansed carefully with a
cloth moistened with alcohol in intervals of 1 week, depending on the air and dust conditions in the room.
Adjustment (direction and focus) of the light barrier can be checked when it is dark in the room.
In case the cleansing of the light barrier does not result in success, you need to check and correct adjustment (direction
and focus) of the light barrier. A special small screwdriver is required for adjustment of the focus. Talk about the
procedure to your h/p/cosmos service partner.
Light barrier must not be exposed to dazzling flash light of cameras. They might turn off and stop
the running belt abruptly.
