Hog Slat Inc. Newton Grove, NC USA May 2017 42 GROW-DISK ™ Feed System For Normally Closed (NC) Sensor Set-up: 1. Turn ON power to chain disk system controller so that the Feed Sensor switch is powered. 2. Remove water tight service plug from back of sensor to reveal “sensitivity adjustment”. 3. If LED indicator is illuminated , turn sensitivity adjustment CLOCKWISE until the LED indicator goes OFF. Then turn sensitivity adjustment COUNTERCLOCKWISE until LED indicator is fully ON (not blinking). 4. To set sensitivity, place index finger on tubing 1/4“ away from edge of sensor. See Figure 3. Adjust sensitivity until LED indicator is OFF. 5. With the chain disk running past the Feed Sensor and no feed in the chain disk tube, the LED indicator may blink as the disks pass by which is acceptable but should not be OFF solid as this would indicate the sensitivity is too high and would send false detection signal to the controller. Turn sensitivity adjustment slowly COUNTERCLOCKWISE until the LED indicator is not OFF solid while the disks pass by. 6. Further adjustment of the sensitivity may be required once system contains feed. If further adjustment is required, simply turn sensitivity adjustment CLOCKWISE to detect objects farther away from the sensor (more sensitive) or COUNTERCLOCKWISE to detect objects closer to the sensor (less sensitive).
