8. TROUBLESHOOTING
The Swing Arm slips from
set position.
The joints require adjustment.
Adjust the joints (refer to Section 8.2 of the
Swing Arm Manual)
Grease the rotation socket.
A) Clean out blockage.
B) Reconnect hose.
C) Replace damaged hose.
D) Open arm damper.
E) Check downstream filters, replace or clean
as needed.
Strong resistance during
rotation of the arm.
Decrease in air volume.
Motor/blower won’t start
or won’t stay running.
Dust emissions from clean
air discharge
Insufficient airflow
Continual excessive
pressure drop (over 5.0”)
on filter monitor gauge.
Pulsing failure of
diaphragm valve.
Filter element installed incorrectly; gasket not
sealing.
Inspect and reinstall filter cartridge (refer to
Section 6.1).
Replace damaged filter element.
Check fan rotation to ensure clockwise
rotation (refer to Section 5).
Check for obstructions and clear.
Replace filters.
Cleaning system not being used at required
frequency. Increase frequency.
Check air supply pressure (should be 90-110
PSIG).
Replace filters.
Check continuity of solenoid coil with
ohmmeter. Replace if necessary.
Filter element damaged.
Fan rotation backwards.
Air inlet restricted.
Filters at end of service life.
Plugged filter elements.
Inadequate compressed air supply for
cleaning mechanism.
Filter elements at end of useful life.
Open solenoid valve.
Improper electrical supply.
Refer to Section 7 for electrical specifications.
Starter overloadtripped.
Reset overloads.
Lack of grease in the rotating socket.
A) The ventilation duct is plugged.
B) Flexible hose not properly connected to
arm tubes.
C) The flexible hose is damaged.
D) The Swing Arm damper is closed.
E) Packed filters or other
restriction in system.
PROBLEM
POSSIBLE CAUSE
RECOMMENDED SOLUTIONS
Timer does not operate.
“PWR” light dose not illuminate.
Downtime cleaning does not function.
PWR light not illuminated.
Downtime cleaning does not function.
PWR light illuminated but CLEAN light not
illuminated or flashing.
Downtime cleaning does not function.
CLEAN light flashing but valve does not
pulse.
1. Make certain 120VAC power is at terminals L and N.
2. Check fuses F1 and F2 for open circuit. If F1 is open, check wiring and
replace fuse. If F2 is open, replace board.
1. Make certain 120VAC power is at terminals L and N even after the
motor/blower is turned off. The PWR light should be illuminated.
2. In units with motor starters: make certain an isolated normally open
motor starter auxiliary contact is wired to terminals 13 and 14 (downtime
cleaning begins when the motor/blower starter is turned off.)
1. Check terminals V and N for 120VAC pulse. If no output when PULSE
light flashes, replace board. If 120VAC pulse is detected, check wiring,
valve coil and air supply.
