Sterling 882.00379.00 manual Starting ACA Series Filter Chamber Units

Starting ACA Series Filter Chamber Units

With all adjustments complete, turn on clean, dry, oil-free compressed air and regulate to 60 psi to 80 psi (414 kPa to 552 kPa). Turn the power on/off switch to ON; the unit then automatically self-cleans the filter bags. An indicator light on the control box for Model 91/93, 151/153, and 251/253 ACA filter chambers illuminates each time a compressed air pulse is directed into a filter bag.

Note: If for any reason the power is turned off, wait at least three (3) seconds to reset.

During initial startup, you’ll note some dusting occurring at the clean air exhaust. This condition is normal with new filter bags until the exterior surfaces of the bags become evenly coated with dust particles, which prevents fine material from passing through the filter bag pores. This dusting condition should stop after the first several hours of operation.

Adjusting Proximity Sensor Sensitivity

Models Equipped with Volume-Fill Switch Only

A proximity switch mounted in VF, SSR and SSR vacuum receivers detects when the vacuum receiver has been filled during a conveying sequence, telling the conveying system control to move on to the next on-line vacuum receiver in the sequence. This speeds the conveying cycle and shuts the pump down promptly to conserve electricity if all the bins being loaded are full.

The sensitivity of the vacuum receiver material level sensor can be adjusted. The factory setting is correct for most applications. The sensor is mounted through the wall of the vacuum receiver.

Note: The adjusting potentiometer is located beneath a plastic cover screw near the sensor LED indicator. Remove the protective cover screw before making adjustments and replace it when finished.

Note: Before adjusting the Receiver-Full sensor, make sure that the Bin Full sensor is in the closed position.

When adjusting, fill a vacuum hopper to see if the switch detects your material. The LED on the switch goes out when it detects material.

∙For increased sensitivity, turn the potentiometer clockwise.

∙For decreased sensitivity, turn the potentiometer counterclockwise.

∙Consult proximity switch instructions if necessary or call Service Department.
