BOOM JOYSTICK CONTROL CALIBRATION
SUB-D
This Electronic control valve is now equipped with higher-resolution actuators on Main Boom,
Secondary Boom, Deck Roll, and Swivel functions. These actuators have active fault monitoring.
The Deck Shield section does not have active fault monitoring. The joystick is unchanged and
provides a ratio-metric voltage signal. The neutral signal voltage is half or 50% of tractor supply
voltage. A 25% signal voltage will shift the valve spool to full A-Port, and 75% signal voltage will
shift the spool to full B-Port in the Main, Secondary, and Swivel valve sections. On the Deck Roll
function a 34% signal voltage will shift the valve spool to full A-Port and a 68% signal voltage will
shift the spool to full B-port. If an actuator with active fault monitoring receives a signal from the
joystick that is less than 15% or greater than 85% of supply voltage the actuator will “fault out”
and shut down. Also, if there is an internal failure in the actuator or if the spool position is greater
than that specified by the signal voltage from the joystick, the actuator will “fault out” and shut
down. An “active fault” condition causes the actuator to drive the spool to neutral, shut down,
and activate a red LED on the top of the actuator. The active fault can be canceled by simply
cycling the Master Switch OFF and then ON, which resets the fault monitoring, and causes the
LED on top of the actuator to be green again.
The joystick control is equipped with signal adaption potentiometers.
These provide the capability to individually adjust the oil flow to each boom function. It is
important that the boom functions do not travel too fast. Excessive boom speed can reduce the
stability of the unit and decrease operator control.
Note: Use a Phillips screwdriver and be sure to adjust the screws carefully! DO NOT turn
the potentiometers beyond their stopping point, potentiometers are very delicate! Turning the “A”
or “B” port potentiometers clockwise increases the oil flow to increase the boom function speed,
and turning them counterclockwise decreases the oil flow to decrease the boom function speed.
See the graphic on the next few pages for help in adjusting.
