Mechanical Description Of The System 4
Basic Adjustment Of The Components
Length: Ensure that the length cable tension is correct with fully retracted boom and no tension on the
cable reel. Turn the cable drum 5 to 8 turns counter clockwise. Then remove cover from cable reel
and adjust the potentiometer counter clockwise to end stop. See Procedure 3.
Angle: Set the boom between 0 and 5 degrees and set the inclinometer to the boom angle. Adjust
the angle sensor to the same angle as the boom. Check the angle at 20 degrees, 45 degrees, and 70
degrees. Angle display should be less than

.5 degrees of the value of the inclinometer. See
Procedure 3.
Pressure Channel: Rest the boom and disconnect hydraulic hoses from the pressure transducers.
Measure and record the zero-points of both pressure transducers on the main board. Adjust P1 and
P2 on the main board to 500mV at test points MP11 and MP12. Connect hydraulic hoses back to the
pressure transducers. See Procedure 2.
Duty Selection Switches Digital Inputs): Check the duty selection switches for correct operation.
Check the voltage on digital input connections.
Check the function of the hoist limit switch (anti-two-block)
Check function of lever lockout.
Measure and record the power supply voltages. See Addendum A.
