TROUBLESHOOTING
WARNING
To avoid serious injury, observe the following
when troubleshooting:
Turn OFF the compressed-air supply,
bleed the supply line, and lockout and
tagout the air supply.
If checking the controls requires air,
always enlist the aid of another person to:
•
Hold the blast gun securely.
•
Operate the foot pedal.
Never bypass the foot pedal or wedge it in
the operating position.
Never bypass the door interlock system.
Follow all OSHA regulations, including
lockout and tagout procedures.
8.1
Poor visibility
8.1.1
Dirty filter cartridge. Empty the dust container.
Pulse cartridge several times, per Section 6.2.4. Inspect
cartridge and replace when necessary.
8.1.2
Exhauster motor not operating. Check voltage to
motor and motor wiring.
8.1.3
Check rotation of exhauster motor; the motor
should rotate as indicated by the arrow on the housing. If
it does not rotate in the proper direction
, lockout and
tagout electrical power
and switch motor leads, as
shown on the motor plate.
8.1.4
Using friable media that rapidly breaks down, or
using media that is too fine or worn out. Check condition
of media.
8.1.5
Outlet damper closed too far, restricting air
movement through the cabinet. Adjust static pressure,
per Section 5.4.
8.1.6
Inlet damper closed too far, restricting air
movement into the cabinet. Adjust damper, per Sections
2.5 and 5.7.
8.1.7
Reclaimer door open. Check door.
8.1.8
Hole worn in flex hose between cabinet hopper
and reclaimer inlet, or reclaimer outlet and dust collector
inlet. Replace hose.
8.1.9
Obstruction in flex hose between the cabinet
hopper and reclaimer inlet. Inspect hose for blockage.
8.1.10
Paddle wheel worn. Check wheel for wear.
8.2
Abnormally high media consumption
8.2.1
Door on reclaimer open or worn door gasket. Air
entering the reclaimer around the door will cause media
carry over to the dust collector. Inspect door gasket. DO
NOT operate unless all doors are closed.
8.2.2
Outlet damper open too far. Adjust static
pressure, per Section 5.4.
8.2.3
Media may be too fine or worn out. Check
condition of media.
8.2.4
Using friable media that rapidly breaks down.
Check condition of media.
8.2.5
Blast pressure too high for the media, causing
media to break down. Check blast pressure and adjust
as needed or switch media.
8.2.6
Hole worn in reclaimer or leak in reclaimer seams.
Check entire reclaimer for negative-pressure leaks.
8.3
Reduction in blast cleaning rate
8.3.1
Low media level reducing media flow. Check
media level and replenish or replace as needed.
8.3.2
Media-air mixture out of adjustment. Adjust
metering valve, per Section 5.3.
8.3.3
Reduced air pressure. This may be caused by
the pressure regulator set too low, a malfunctioning
regulator, a dirty filter element in the air filter, partially-
closed air valve, leaking air line, or other air tools in use.
Inspect all items.
8.3.4
Blockage in media hose or gun. Blockage may
occur as a result of
A damaged or missing reclaimer screen, inspect
screen.
Heavy media flow. Adjust media flow, per Section
5.3.
8.3.5
Worn gun parts such as nozzle or air jet. Inspect
and replace all worn parts.
8.3.6
Worn media hose. Check hose for leaks and
soft spots. Replace if worn or damaged.
8.3.7
Air jet in gun out of adjustment. Check
adjustment, per Section 5.2.
8.3.8
Moist media. Frequent bridging or blockage in
the area of the metering valve can be caused by
moisture. Refer to Section 8.5.
