less than 60 mV
Note: Table shows voltage under non-attenuation sheet condition.
Testing the unit: Test monthly. Walk in front of the receiver
and see if the Alarm LED lights when the beam is blocked.
Confirm the relay function by observing the status light on the
control panel.
Maintaining the unit: The units are virtually maintenance free
except for units located in dusty or dirty locations. Clean dirty
units with a damp cloth as necessary.
Adjusting the response time
See Figure 15.
Response time (sec.). 1. Response 0.05 sec: running at full
speed. 2. Response 0.3 sec: walking quickly; 3. Response 0.7
sec: walking.
This feature is used to modify the response time of the beam to
best suit the application. The unit cannot detect objects that
move faster than the set response time. However, increasing
the set response time may result in the unit not detecting
people.
Changing beam frequency
Change the beam frequency to prevent cross talk or bypass of
beams. This can occur with line or 2-stacked protection.
Figure 16: Setting the beam channel.
1. Set the transmitter and receiver to the same channel. The
units do not provide protection if set to different channels.
2. See figure 16 to set the beam channel when installing two
or more units in a line or 2-stacked protection.

protection.
Note: When multi-stacked or line protection is used, it is
recommended that beam alignment is done with a tester to
improve reliability as well using the beam frequency change-
over function. When multi-stacked protection is used, both
upper and lower sensors should have the same model
numbers.
