TROUBLESHOOTING
If loading is a problem:
1. Be sure: Filter dust collector is "in place" and vacuum tight.
2. Be sure: The material fill "turret" in the top of each receiver is properly in place.
3. Be sure: Air pressure is reaching all the cylinders as well as the Vacuum Blower
Station. Without air pressure, the system will not develop vacuum.
4. Be sure: All signal lines are connected properly at the controller.
5. Be sure: The level sensor, at the bottom of each receiver, is adjusted correctly so it
does not send back a false "covered" signal. See ADJUSTMENTS to
adjust sensor.
6. Check Filter: If the container has an excessive amount of material in it, you may be
loading a receiver to too high a level. Shorten load times so receivers do
not overfill.
Smaller loads do NOT significantly reduce conveying rate.
Stations simply load more frequently.
7. Excessive high vacuum will overheat the blower. A thermal switch is provided in the
exhaust air steam, which trips out at 190F, keeping the air bypass valve open. This
cools the blower, but loading cannot occur during this time. If this happens, check main
filter and receiver screens for blockage.
MECHANICAL ADJUSTMENTS
SENSOR There is a small screw in the rear of the sensor to adjust the sensitivity of the
sensor. Turning it Clockwise (CW) will increase sensitivity. CCW will decrease.
(Some sensors have a plug in front of the adjustment screw, which must first be
removed. The adjusting screw is recessed.)
The LED light is ON when the sensor is COVERED. It is OFF when
UNCOVERED.
To adjust: Make sure sensor is UNCOVERED.
Turn screw inward (CW) until the LED goes ON.
Turn outward slowly (CCW) until it just comes OFF.
Turn 1/4 turn more (CCW).
Now TEST for correct operation.
Cover with hand, LED should light.
Uncover, it should go OFF.
