If you are not able to activate one or many functions of the joystick, check
if the valve received a signal from the controller. When you activate a
function, there’s a light on the valve (Photo 1). The blue connector is for
the pusher, the brown is for the loading arm and the yellow is the arm’s
extension. If you see a light and nothing seems to work: A-TRB-003
Verification of the spool.
If there’s no light and the controller is working
fine, check if the power is going to the vale (use a voltmeter). If the test is
positive, check the adjustment of the limit switch A-TRB-005 Adjustment
of the limit switch or replace the valve. The problem could also come
from the joystick or the wiring.
