Control Calibration
See Figure 3-68 for the following procedure.
Control calibration calculates pump threshold command
level for all drum and swing functions.
Perform this calibration when:
- A new pump or motor is installed in a drum or swing
- A new master node or software is installed
- Operation indicates threshold is in error
- Excessive handle motion or time required to
initiate motion
- Inability to smooth start motion
Calibrate controls as follows:
1. Apply all park brakes with switches on control console.
2. Start and run engine at high idle.
3. Press Enter button to go to Pressure Test and
Calibration screen from Menu screen.
4. Press Enter button to go to level 2. Use
Select buttons to show CONTROL
CALIBRATION icon in data box.
5. Press Confirm button to start test.
6. Calibration starts and percent of completion is displayed
in data box.
7. When calibration is complete, control calibration icon
reappears in data box.
Pump threshold command levels must be within a
specified range during this test. Any pump requiring a
threshold command level outside this range is
highlighted yellow. Troubleshoot failed circuit to
determine cause of fault.
High Pressure Test
See Figure 3-69 for the following procedure.
The high pressure test checks ability of all primary crane
functions to reach and hold high pressure. This test generally
is used only as a shop procedure on new cranes. It can also
be used as a quick way to test hydraulic components in
primary hydraulic circuits.
CAUTION: Only perform this high pressure test when
absolutely necessary and by a qualified service technician.
Test high pressure as follows:
1. Apply all park brakes with switches on control console.
2. Start and run engine at high idle.
3. Press Enter button to go to Pressure Test and
Calibration screen from Menu screen.
4. Press Enter button to go to level 2. Use
Select buttons to show HIGH PRESSURE
icon in data box.
5. Press Confirm button to start test.
WARNING
High Pressure Hazard!
This test generates maximum pressure in the main
hydraulic circuits. Defective brakes may allow unintended
motion during test. Move crane to an area where such
motion is not a hazard.
We recommend an observer to monitor functions the
operator cannot see.
Be prepared to stop engine if unintended motion occurs.
