AD-410 MACHINE OPERATION TROUBLESHOOTING INFORMATION

END OF CYCLE/HEATER FAULT INDICATOR

The “END OF CYCLE” light located on the top/front of the dryer, is triggered by the Air Jet Signal of the
Phase 5 Microprocessor Controller (computer) to the input of the PLC (Programmable Logic Controller). If this
signal is not sensed by the PLC the light will not turn on. The “1-second flashing” is accomplished by a “Flasher
Module” located on the Main Control Panel in the Right Front Control Cabinet. Refer to the electrical blueprints
included with this machine for detailed signal routing.
The “HEATER FAULT” signal is an output of the PLC (Programmable Logic Controller) to the “END OF
CYCLE” light. A “HEATER FAULT” is an indication that a malfunction has occurred in the “Gas Heat Circuit”
and needs attention. Refer to the “HEATER FAULT” explanations on page 10 and page 11 for more informa-
tion on this subject.
If this “END OF CYCLE" light fails to display at the end of every cycle;
1. Check the bulb.
2. Check voltage to the bulb (24 VAC).
3. Refer to the ladder diagram and the schematics provided with this machine for detailed signal information for
higher level troubleshooting.
JOG (Forward / Reverse Push-Button)
Forward “JOG” is in the clockwise (CW) direction and Reverse “JOG” is in the counterclockwise (CCW)
direction.
There is a seven (7) second dwell (delay) time between a selection of a different rotation direction. This delay is
to prevent plug starting the tumbler drive motor.
If the “JOG” function does not operate in the tilted position;
1. Check that the Main Doors are fully opened.
2. Check that the Overload for the Drive Motor is in the “Start” position.
3. Check that the Overload for the Tumbler Motor is in the “Start” position.
4. Check that the Lint Drawer is closed.
5. Refer to the ladder diagram and the schematics provided with this machine for detailed signal information for
higher level troubleshooting.
AIR JET
If this selection does not operate;
1. Check the air supply to the dryer (set at 80 PSI).
