• If no, check associated:
• Switch and Wiring
• Check wiring back to the Base Electrical Junction Box
• Check PLC (Programmable Logic Controller)
• Refer to Wiring Diagrams:
• Main Electrical Panel Diagram
• Base Electrical Junction Box Wiring Diagram.
•Retest; verify that the signal is operational.
3b) Place the AD-464 in the UNLOAD position; TILTED FORWARD
• Actuate the Rear Down switch by hand.
• Have someone verify that PLC (Programmable Logic Controller) input L.E.D. (light emitting
diode) #12 lights when the switch actuator is down, and is OFF when the actuator is up.
• Does L.E.D. (light emitting diode) #12 come “ON” when the switch is down?
• If yes, wiring is OK.
• Check switch, actuator placement and tilt actuation.
NOTE
: If actuator is at a 90° or greater angle with the base, the actuator will damage if machine is
lowered.
• If no, check associated:
• Switch and Wiring.
• Check wiring back to the Base Electrical Junction Box.
• Check PLC (Programmable Logic Controller).
• Refer to Wiring Diagrams:
• Main Electrical Panel Diagram
• Base Electrical Junction Box Wiring Diagram.
•
Retest; verify that the signal is operational.
