ATTENTION!
Never attempt to override the interlock system.
Doing so could result in injury from unexpected blasting.
pace. The correct mixture of air and abrasive can generally be distinguished by a slight
discoloration at the exit of the nozzle.
4.3.3 Reclaimer static pressure
Correct static pressure varies with size of reclaimer and the size, weight and type of
media. Adjust reclaimer static pressure by opening (handle horizontal) or closing (handle
vertical) the damper on the dust collector inlet.
If the damper is not opened enough, the reclaimer will not remove fines, resulting
in dusty media, poor visibility, and possible media blockage in the conveying hose. If the
damper is opened too far, it may cause carryover (usable media carried into the dust
collector) and result in excessive media consumption. Open only as far as necessary to
obtain a balance of dust removal without media carryover.
4.3.4 Cabinet static pressure
Once the inlet is initially set per section 4.1.5, it seldom requires readjustment.
The initial setting produces approximately 50% to 75% of static pressure in the cabinet
enclosure. For adjustment open the inlet damper further to decrease static pressure or
close it further to increase pressure.
Use the gloves as an indicator of right cabinet static pressure. With the exhauster on,
the gloves should be inflated, but not elevated off the grate.
4.3.5 Door Interlocks
The door interlocks disable the blasting control circuit when the doors are open. To enable
blasting, the door interlock switches must be engaged when the doors are closed. The interlocks
are set at the factory and do not usually require field adjustment unless parts are replaced.
To adjust the actuator, bend it by hand as required for engaging the switch by full
closed door.
