•If “NO,” check associated:

•Switch and Wiring

•Check wiring back to the base electrical junction box

•Check PLC (Programmable Logic Controller)

•Refer to the blueprints: Main Electrical Panel Diagram, Base Electrical Junction Box Wiring Diagram

•Retest; verify that the signal is operational

1b) Place the MLS-460 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. #12 lights when the switch actuator is down, and is OFF when the actuator is up

•Does L.E.D. #12 come “ON” when the switch is down?

•If “YES,” wiring is okay

•Check switch, actuator placement and tilt actuation

NOTE: If actuator is at 90º or greater angle with the base, the actuator will be damaged 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 blueprints: Main Electrical Panel Diagram, Base Electrical Junction Box Wiring Diagram

•Retest; verify that the signal is operational
