Selectable 4-Channel Beam Frequency; Beam Frequency Selection Chart; (E-964-D390Q Model Only) Multiple Sensors Sample Applications - SECO-LARM SLI Enforcer E-964-D390Q Manual

Selectable 4 – Channel Beam Frequency (For E-964-D390Q Model Only):
The sensor beam frequency can be set at different levels on-site to avoid interference from other
twin photobeam sensors nearby, which is useful during multiple sensor applications as shown
below. To select between four different beam frequencies, adjust the beam channel switch of the
transmitter side and receiver side. See fig. 1 for switch location and table 2 for switch position.
Important -
The transmitter and receiver sensor pair must be set with the same frequency.
