4.RTD (Resistive Temperature Device) WIRING TO THE “EXHAUST” 4 to 20 MILLIAMPERE (4 to 20 mA) TRANSMITTER
Check ALL wiring and ADS-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 ADS-464 EXHAUST Temperature Assembly and Wiring Diagram, ADS-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 ADS-464 Main Panel Wiring Diagram.
F.MOTORS
INTRODUCTION
The four (4) motors installed on the ADS-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 ADS-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:
•ADS-464 MAIN PANEL WIRING DIAGRAM
•ADS-464 SYSTEM BLOCK DIAGRAM
•Motor Actuating Device Information
ALL ADS-464 motor contactors have 110 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).
•Motor Protection Device Descriptions
The motor protection devises in the ADS-464 incorporate a manual disconnect switch, thermal overload relay, and instantaneous trip mechanism in one compact device. A two (2) position, normally open, auxiliary contact block has been attached to ALL motor protection devices to provide the “MOTOR FAULT” display message, and shut down “ALL” motors in the event a motor should trip.
