E. Pressure holds constant in air tank - Pneu-jet Blast Valve Fails to Fire
Probable Cause/Suggested Remedies:
1. Check power to the controller.
2. Check LED output indicators.
3. Check for power at the solenoid or for a faulty solenoid.
4. Check operator assembly of the 2 way solenoid valve to see if it is broken. (If the valve is faulty,
replace the valve or diaphragm.)
F. Cleaning Pressure Varies
Probable Cause/Suggested Remedies:
1. Check “off” time potentiometer.
2. Check “on” time potentiometer.
3. Check for skipping in bag cleaning sequence (pneu-jet blast valve not firing).
G. Pressure in Air Tank will Not Build
Probable Cause/Suggested Remedies:
1. Check the air line from the Air Power Unit to the tank.
2. Check the inlet filter on the Air Power Unit and clean or replace as required.
3. Check for leaks:
a. Check the Pneu-Jet blast valves for leaks
b. Check to see if any of the Pneu-Jet blast valves are stuck open and bleeding the tank air
straight to the filter. (The electric operated 2 way pilot exhaust valve being stuck open usually
causes this. Check by manually plugging the exhaust port.)
c. Check the air piping for leaks.
d. Check the couplings for leaks between the air tank and Pneu-Jet blast valves.
4. Check that the Air Power Unit motor is energized and that the blower is operating with the proper
rotation.
H. Sequence Controller Troubleshooting
Probable Cause/Suggested Remedies:
1. Check input power.
2. Observe RED power light:
a. If power light is not on, check fuse.
b. If fuse is OK, replace timer board.
3. Before replacing blown fuse, disconnect power and check output circuits only for short circuit.
Correct, if necessary.
4. Replace fuse.
5. Apply power while watching output lights for proper function.
6. Make sure cycle starts at output #1, continues to last output selected, and then restarts.
