Transmitter/receiver sets programmed for Group A
Transmitters emitting beams that are assigned to Group A do not interfere with receivers
collecting beam signals from transmitters assigned to Group B. The same holds true for
transmitters assigned to Group B not interfering with receivers assigned to Group A. The
frequencies emitted from Group A are different than the frequencies emitted from Group B,
and therefore do not interfere with one another.
Channel selection
Selecting different channels (frequencies) on the transmitter/receiver sets allows you to
further expand your photobeam stacking capabilities and coverage. Multi-stack configurations
allow you to increase the area of protection with respect to height This occurs by assigning
each stack (row) a specific channel setting as you build multiple photobeam stacks, one above
the other. Beam crosstalking and interference between stacks are eliminated as each stack
(row) has its own unique channel.
When installing multiple stacks, the initial stack must be assigned as the Master (notated as
“M” in the corresponding tables located on each transmitter and receiver). Each additional
stack is assigned a separate channel number (1 to 3). You cannot have a multiple stack
configuration without assigning one stack as the Master. Refer to the transmitter and receiver
illustrations in the previous section for channel programming and dip switch locations
(Channels 1 to 3).
