Computer Logic and Wiring Diagram | ADC 450428 specification

E. COMPUTER LOGIC and WIRING DIAGRAM

1.Operator enters desired selections.

2.Information entered is sent to the microprocessor (computer) via the keyboard (touchpad).

3.The input information is sorted, processed, and executed by the microcomputer chip.

4.The microcomputer output signal activates the contactors and HSI (Hot Surface Ignition) module which control machine functions.

NOTE: When contacting ADC with electrical questions, please have on hand the correct wiring diagram number for your particular machine. This number is located on the top right-hand corner of the diagram. It is a six (6) digit number followed by a letter to distinguish the revision dates (refer to illustration).

The wiring diagrams used in troubleshooting are specifically for dryers manufactured at the time of publishing. Your particular model may vary slightly depending on the date of manufacturing and options available. The correct wiring diagram and number is either taped to the rear of the control door or each dryer, or placed in the control box. If your particular diagram is lost or unreadable, call ADC with the serial number of the dryer. ADC will be more than happy to send you a diagram by fax or mail.
