If the power supply responds to the disconnection, there is a problem with the driven load and not the power supply itself.

Check ALL loads and retest.

Check that the device’s output voltage is 24 volts DC.

If not, adjust it.

3.DEFECTIVE ANALOG INPUT MODULE or CHANNEL Replace Analog Input Module

4.RTD (Resistive Temperature Device) WIRING TO THE “EXHAUST” 4 to 20 MILLIAMPERE (4 to 20 mA) TRANSMITTER

Check ALL wiring and AD-464 connection from the exhaust RTD (Resistive Temperature Device) probe to the exhaust 4 to 20 milliampere (4 to 20 mA) transmitter. Refer to the AD-464 EXHAUST Temperature Assembly and Wiring Diagram, AD-464 Main Panel Wiring Diagram.

5.CIRCUIT WIRING TO THE ANALOG INPUT MODULE

Check ALL wiring and connections from the 4 to 20 milliampere (4 to 20 mA) transmitter to the PLC (Programmable Logic Controller) Analog Input Module. Refer to the AD-464 Main Panel Wiring Diagram.

G.MOTORS

Introduction

The four (4) motors installed on the AD-464 are connected directly to associated thermal magnetic starters in the main electrical enclosure. The troubleshooting information includes in this section will cover the actuation, power control and safety devices to these motors.

The AD-464 motors include:

MAIN BLOWER FAN MOTOR

BURNER FAN MOTOR

LEFT (Basket) TUMBLER MOTOR

RIGHT (Basket) TUMBLER MOTOR

Refer to the following diagrams for functional, and wiring information:

AD-464 MAIN PANEL WIRING DIAGRAM

AD-464 SYSTEM BLOCK DIAGRAM

Motor Actuating Device Information

ALL AD-464 motor contactors have 120 volts 50/60 Hz actuation coils. Three (3) motor contactors are actuated by outputs from the PLC (Programmable Logic Controller), and one contactor is actuated by the Burner Controller Module (BCM).
