5.0 - Troubleshooting List for Injection Cleaning System
Power is not supplied to PC board.
Ensure the unit is plugged in; ensure there is no loose or short
wiring between primary & secondary of transformer and the
24VAC power inlets of PC Board.
Filter is not sealed properly
Check the compression mechanism on top of the inner chamber
lid. Insert appropriate Spacer. (Refer to Filter Spacer Chart)
Loose connection between PC board
and motor.
Check motor connection. When the “UP” light is ON, the motor
should be rotating the nozzle upwards; and downwards when
the “DOWN” light is ON. (Refer to the electrical diagram)
This could be a result of the nozzle
being jammed, or of something
restricting free movement of the
nozzle.
Locate and repair the cause of the physical restriction before
operating the system.
Limit switch needs alignment
Push limit switch forward or backwards to align with the Nozzle
Assembly switch disc
System is NOT turning and no air
comes out of the nozzle.
Upon a cleaning cycle, the “SOLN1” light turns ON indicating
power is being supplied to the solenoid.
Check the wiring between the PC board and the solenoid for
any possible bad connections.
Check if solenoid is operational. This can be done by jumping
the solenoid leads to the secondary side of the transformer.
(24VAC)
If both wiring and solenoid are in order, the PC board might
need to be changed.
System turns but no air comes out
of the nozzle.
Ensure that air pressure is 80-100psi and Minimum 80CFM
The nozzle is blocked by dirt or
other contaminant.
Remove blockage from the nozzle.
Check if pneumatic filter is filtering air properly. Its filter unit
might need to be replaced.
Not enough air coming out of the
nozzle.
There is an air leak in the pneumatic
system.
Verify pneumatic system for leaks and tighten or change hose
clamps or hoses.

5.1 - Debugging
Things to check
When the machine is first plugged in, the mechanism will move to a “home” position. Once the nozzle is at home
position, the system is ready. The cleaning cycle is controlled by a microprocessor based PC board located in the
control box. The microprocessor has been programmed to turn on the cleaning system once the start button is
pressed and released, and the filter is sealed. The nozzle will travel from its home position (located at the bottom)
through the top and back down to home. The home and top positions are sensed by Limit Switch and Proximity
Sensor respectively. Simultaneously, when the gear motor is engaged, an in-line solenoid opens and allows
compressed air to reach the nozzle or the pneumatic vibrator motor. If for some reason the lid is open before the
cleaning system has had a chance to terminate the cycle, the system will shut itself and the unit will resume from
where it left off once the Cabinet lid is closed.
