3. If Air Jet L.E.D. (light emitting diode) is on then check the wiring from the Phase 7 Microprocessor Controller
(computer) to the air valve.
4. Faulty 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 load doors only
If this selection does not operate;
1. Check that 80 PSI (5.512 bars) 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 (basket) section releases the tilt switch, the
JOG functions become enabled for an operators selection.
If the tumbler section does not tilt forward;
1. Verify that a Door Open signal is being sensed by the PLC.
2. Check that 80 PSI (5.512 bars) of compressed air is supplied to the machine and that the Rear Up solenoid
is being actuated by the PLC.
Refer to the PLC 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
enables the Front Up solenoid to tilt the machine. The JOG functions then becomes enabled for an operators
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).
2. Check that 80 PSI (5.512 bars) of compressed air is supplied to the machine and that the Front 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.
