American Dryer Corp ML-410 System Ladder Diagram, Tumbler Temperature and HI-LIMIT Information

SYSTEM LADDER DIAGRAM

The SYSTEM LADDER DIAGRAM is an overview on the electrical connections of the ML-410. This diagram is for signal flow information and is a tool to direct an individual in the correct direction for troubleshooting this machine.

The ML-410 system is divided into a number of “electrical” sections which are as follows:

1.Right Front Control Panel

The RIGHT FRONT CONTROL PANEL is located in the Right Front Control Cabinet of the ML-410. This panel is the heart of the drying system, where ALL control signals interface to or from this panel. The signals that interface to this panel are too many to list here, however, they are ALL identified on TB1 of its’ schematic diagram.

2.Right Base Electrical Enclosure

The RIGHT BASE ELECTRICAL ENCLOSURE is located towards the front of the right base section. An industrial multi-pin connector is used to connect the base section control signals to the tumbler (basket) section’s main control panel. This electrical enclosure is labeled CAUTION, HIGH VOLTAGE IS PRESENT IN THIS ENCLOSURE and incorporates the following electrical devices:

The MAIN ELECTRICAL POWER to the machine

The ELECTRICAL CONNECTION for the “OPTIONAL” SPRINKLER CIRCUIT POWER

The THERMAL/MAGNETIC OVERLOAD and CONTACTOR for the BLOWER MOTOR

3.Right Base Interface Junction Box

The RIGHT BASE INTERFACE JUNCTION BOX is located towards the rear of the right base section and is used as a central location to interface the base section electrical components to the TILTING tumbler (basket) section. An industrial multi-pin connector is used to connect the base section control signals to the tumbler (basket) section’s main control panel. The control signals incorporated in the Right Base Interface Junction Box are:

SOLENOID CONTROL

Front Up/Front Down

Rear Up/Rear Down

Open Front Door

Supply Air Enable

Air Jet
