2.1. SENSOR ALIGNMENT
The Emitter and Receiver sensor enclosures are mounted on either side of the
conveyor belt. Once connected and power up, the alignment of the units is confirmed
when both the G
REEN and YELLOW LED’s on the receiver sensor are ON (not
flashing). This indicates that the signal strength is at least twice that required to
energize the output. If the Green LED is flashing or if the Yellow LED is not on, the
sensors are not correctly aligned.

Ideally the beam should be set approximately 20-25mm underneath the conveyor
belt to achieve maximum effectiveness.
