Hog Slat Inc. Newton Grove, NC USA May 2017 41 GROW-DISK ™ Feed System Adjustment: Make sure there is no feed in the clear section of tube and there is not a disk section of the chain directly in front of the sensor. For Normally Open (NO) Sensor Set-up: 1. Turn ON power to chain disk system controller so that Feed Sensor switch is powered. 2. Remove water tight service plug from back of sensor to reveal “sensitivity adjustment”. 3. If LED indicator is not illuminated , turn sensitivity adjustment CLOCKWISE until the LED indicator comes ON. Then turn sensitivity adjustment COUNTERCLOCKWISE until LED indicator is fully OFF (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 ON. 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 ON 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 ON 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). FIGURE 3 Place index figure in this location. Keep fist together and only extend index finger to prevent false reading . Keep area around sensor clear while performing this set up.
