2 General safety instructions
The MSL multibeam photoelectric safety
switch consists of two components: the
sender unit MSLS and the receiver unit
MSLE (
top diagram). Between the two
units, the individual beams of light create
a protective field defined by the number
of beams and their spacing. The position
of the light beam is indicated by a
marking on the housing.
On the MSLZ the sender and receiver
units are in one housing (column) -
bottom diagram.
If an object interrupts at least one beam
of light (manual intervention or me-
chanical obstacle) the receiver unit
sends a Stop signal to the machine or
plant. This prevents the machinery from
starting or stops a hazardous movement.
The device can only perform its safety
function if it is correctly connected and
mounted.
