HYDRAULIC SYSTEM TEST, CALIBRATION,
AND ADJUSTMENT PROCEDURES
It is only necessary to perform the following procedures at
the specified intervals or when instructed to do so during
troubleshooting (see Section 10 of this manual).
Pressure Test and Calibration Screen
NOTE: To understand operation of the main display and
touch pad controls, read instructions in Section 3 of
this manual.
The Pressure Test and Calibration Screen (see Figure 2-21
)
initiates and monitors the four hydraulic test and calibration
procedures described in this section.
The screen shows pump commands and pressure levels for
all primary crane functions. Use data box in upper left corner
of the screen to select and start a specific test or calibration
procedure.
Pressure Test and Calibration screen operates on two
levels.
Level 1 — Test data box highlighted blue.
Level 2 — Test data box highlighted red. Use Select buttons
to choose the test or calibration procedure.
All test and calibration procedures must be run at a particular
engine speed. If a test is started at the wrong speed, the
appropriate prompt shown below appears in the data box
and the procedure is aborted.
Engine Off
A yellow engine pressure 0 icon indicates that test
must be run with engine off.
Engine Low Idle
A yellow engine pressure down arrow icon
indicates that test must be run with engine at low
idle.
Engine High Idle
A yellow engine pressure up arrow icon indicates
that test must be run with engine at high idle.
The yellow open circuit icon indicates a circuit fault
that must be serviced immediately.
The yellow short to ground icon indicates a circuit
fault that must be serviced immediately.
Pressure Sender Test
See Figure 2-21 for following procedure.
The pressure sender test calculates the zero-pressure
output level for each pressure sender.
Perform this test when:
- A new pressure sender is installed.
- A new controller node that monitors pressure
senders is installed.
- A new master node or master node software is
installed.
- Pressure readings are noticeably in error.
Be aware that if there is any residual pressure in the
system during the calibration process, the display
pressure reading in the cab may not reflect actual
system pressure. See Note below.
Test pressure senders as follows:
1. Stop engine and turn ignition switch to run position.
Push Enter button to go to Pressure Test and Calibration
screen from Menu screen.
2. Press Enter button to go to level 2. Use
Select buttons to show PRESSURE
SENDER icon in data box.
3. Press Confirm button to start test.
4. Test starts and percent of completion is displayed in data
box.
5. When test is complete, pressure sender icon reappears
in data box.
Pressure senders must show a signal within a specified
range during this test. Any sender signal out of this
range is highlighted yellow. Troubleshoot failed senders
to determine cause of fault.
NOTE: The cause of a failed pressure sender test or faulty
display pressure reading may not be the pressure
sender. The cause of the fault could be trapped air
or hydraulic pressure in the system during the
pressure sender test.
