Service and Repair Manual
7 Momentarily activate the drive enable toggle
switch in the right direction until VALVE AND
SENSOR SETTINGS is shown on the display.
8 Momentarily activate the drive enable toggle
switch in the right direction until CALIBRATE
TILT SENSOR is shown on the display.
9 Momentarily activate steer in the right direction
until VALVE MAXIMUM CURRENT is shown
on the display.
10 Momentarily activate the drive enable switch
to enter the sub menu VALVE MAXIMUM
CURRENT.
High flow functions:
The function speeds are fixed by the flow rate supplied
by the hydraulic pump. Excess flow is rarely produced
resulting in little or no oil going over relief.
11 Momentarily activate and release the high flow
boom function in one direction.
Result: The display shows the name, direction
and current value in milliamps for the function
being moved. Example: “PRI_UP_MAX 590.”
12 Momentarily activate steer right five times to
increase the mA value.
13 Activate the boom function again by pressing
the foot switch and moving the function switch
(or joystick to full speed) in the same direction.
Momentarily active steer left once every three
seconds to decrease the maximum mA value
where pressure rises to about 3000 PSI / 207
bar and an audible alarm sounds.
Note: The turntable function will only increase 300
PSI and no audible alarm. When the 300 PSI occurs,
proceed to the next step.
14 Release the foot switch and momentarily
activate steer in the right direction one time to
increase the value by 10 milliamps. Repeat
releasing the foot switch and momentarily
activating steer right until the function moves
with no valve throttling and no audible alarm for
the primary up/down, secondary up/down and
primary boom extend and retract.
15 Momentarily activate steer in the right direction
three times to increase the value by 30
milliamps for the turntable function setting.
16 Momentarily activate the drive enable switch to
the right to save the value.
Result: The alarm will sound indicating the
setting has been saved. Continue to the next
desired high flow function adjustment.
To exit programming mode:
17 Move and hold the drive enable toggle in the
left position until the display returns to SYSTEM
READY mode.
Low flow functions:
Hydraulic flow from the pump is fixed, and the
function speed is controlled by the hydraulic
directional control valve. Hydraulic flow will always
exceed the flow allowed by the controlling valve
and the excess flow will always be sent over the
relief valve and back to tank. Function speed
is set by changing control current (mA) and is
confirmed by timing the function travel time with a
stop watch. Refer to Specifications,
Performance
Specifications for each boom function speed.
18 Perform steps 1 through 10 to enter the sub
menu VALVE MAXIMUM CURRENT on the
display.
