b. If both lights are on, move your hand in front of the sensor. A red light
on the receiver should turn on when the sensor is blocked and turn off
when the sensor is cleared. If not, the system must be serviced by an
OFITE technician.
5. Clean the sensor:
a. If the green light on the receiver and the red light on the transmitter
are bolt on and a red or orange light on the receiver is on, the sensor
is activated. Check for dirt or debris on the sensor and clean it if
necessary. If the light remains on, the system must be serviced by an
OFITE technician.
6. Check the sensor alignment:
a. The transmitter projects a visible red light. When both sensors are in
alignment, loosen the mounting bracket on the transmitter and adjust
its position.
To confirm the speed of the belt:
1. Measure the length of the belt.
2. Run the Belt Calibration. See page 15.
3. Add an evenly distributed load of 150 lb. to the conveyor belt.
4. Place a mark on the belt and another on the conveyor rail.
5. Set the belt speed to 3.8 ft/min and start the motor (see page 5).
6. Record the time it takes the mark on the belt to travel one complete
revolution.
7. Set the belt speed to 6.33 ft/min and start the motor.
8. Record the time it takes the mark on the belt to travel one complete
revolution.
9. Calculate the belt speed:
Speed = time (min) / belt length (ft)
10. If the calculated speed is 5% over or under the set speed, adjust the
belt tension (see page 20) and repeat steps 6 – 10.
