2. Check to see that the Air Jet L.E.D. (light emitting diode) is on at the end of the drying cycle. If the L.E.D.
is not on it may be an indication of a failed Phase 5 Microprocessor Controller (computer).
3. If Air Jet L.E.D. is on then check the wiring from the Phase 5 Microprocessor Controller (computer) to the
air valve.
4. Bad air valve.
LOAD / DRY / UNLOAD (Selector Switch) and TILT FUNCTION (Off - On Selector Switch)
As mentioned in the machine summary (refer to page 5), the “LOAD / DRY / UNLOAD” selector switch and
“TILT Off - On” selector switch work in conjunction with each other.
UNLOAD or LOAD LEVEL...opens the Vertical Doors ONLY
If this selection does not operate;
1. Check that 80 PSI of compressed air is supplied to the machine and that the door solenoid is being actuated.
The “Door Open” signal is generated by the PLC (Programmable Logic Controller). Refer to the PLC
information included in the ladder diagrams and schematics supplied with the machine.
UNLOAD TILTED
This selection causes the front horizontal doors to open. Once the “Door Open” signal is sensed, the PLC
enables the “Rear Up” solenoid to tilt the machine. Once the tumbler section releases the tilt switch, the “JOG”
functions become enabled for an operator’s selection.
If the tumbler section does not tilt forward;
1. Verify that a “Door Open” signal is being sensed by the PLC (Programmable Logic Controller).
2. Check that 80 PSI of compressed air is supplied to the machine and that the “Rear Up” solenoid is being
actuated by the PLC (Programmable Logic Controller).
Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and
schematics supplied with the machine.
LOAD TILTED
This selection causes the front horizontal doors to open. Once the “Door Open” signal is sensed, the PLC
(Programmable Logic Controller). enables the “Front Up” solenoid to tilt the machine. The “JOG” functions then
becomes enabled for an operator’s selection.
If the tumbler section does not tilt towards the rear;
1. Verify that a “Door Open” signal is being sensed by the PLC (Programmable Logic Controller).
