2. Check that 80 PSI 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.
DRY
This selection prepares the machine for a “Material Drying Command” from the Phase 5 Microprocessor
Controller (computer).
NOTE: Before a drying cycle can be selected, the tumbler section must be in the level position and
both the Front Horizontal Doors as well as the Lint Drawer must be closed.
The PLC (Programmable Logic Controller) senses that the machine is level by the two (2) level switches located
on the left side of the base section. One (1) switch is towards the rear of the machine and the other switch is
towards the front of the machine.
The PLC (Programmable Logic Controller) senses that the vertical doors are closed by the two (2) proximity
switches located at the top center, of the dryer above the doors. These switches are magnetically actuated by
magnets located on the doors.
The PLC (Programmable Logic Controller) senses the Lint Drawer by a push type switch located on the right
side of the lint drawer door.
IMPORTANT: THE LINT DRAWER and LINT DRAWER GUARD MUST BE CLOSED
BEFORE BRINGING THE MACHINE TO A LEVEL POSITION.
If the tumbler section does not return to a level position;
1. Verify that a “Door Closed” 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 “Front Down” or “Rear Down”
solenoid is being actuated by the PLC (Programmable Logic Controller).
3. Verify that the Lint Drawer and Lint Drawer Guard is in the closed position. This signal can be easily verified
since it is a PLC (Programmable Logic Controller) input.
Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and
schematics supplied with the machine.
HEATER FAULT (Indicator/Reset Push-Button) for GAS MODELS ONLY
“HEATER FAULT” refers to a problem in the Gas Heating portion of the machine.
The PLC (Programmable Logic Controller) monitors the Phase 5 Microprocessor Controller’s (computer’s)
Heat Off/On signals to the two (2) individual gas valves that supply the two (2) separate burners.
When a “HEATER FAULT” occurs within the first twenty-five (25) seconds of the drying cycle, the dryer will go
to a “FILL” message on the Phase 5 Microprocessor Controller’s (computer’s) display and both the “HEATER
FAULT"
reset push-button and the “END OF CYCLE" light will flash.
