The (ACS) Actuator Control System system is an option that allows the operator to quickly switch between foot and hand control modes.
The ACS control uses the electric actuators on the main hydraulic control valve to control the lift and tilt spools in the hydraulic control valve, foot sensors, handle sensors and a specially designed control handle.
Hand controls contain a locking solenoid which lock when the switch on the center control panel is switched to foot mode.
Foot controls also contain solenoids which lock when the switch on the center control panel is switched to hand mode.
Both the hand and foot controls contain sensors that relay information to the ACS controller as to which function should be activated and how far the spool should be moved.
