ML-410 MACHINE OPERATION TROUBLESHOOTING INFORMATION
END OF CYCLE/HEATER FAULT INDICATOR
The End of Cycle light located on the top of the ML-410, is triggered by the End of Cycle Signal of the Phase 7
Microprocessor Controller (computer) I/O (input/output) board. 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.
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 (Basket) 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
The Air Jet signal is sent from the Phase 7 Microprocessor Controller (computer) at the end of the drying cycle.
If the air valve fails to operate;
1. Check the air supply to the dryer (set to 80 PSI [5.512 bars]).
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.
(light emitting diode) is not on it may be an indication of a failed Phase 7 Microprocessor Controller
(computer) I/O (input/output) board.
