Charge Pressure Test
See Figure 3-64 for the following procedure.
The charge pressure test checks the ability of all primary
cane functions to build proper charge 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. Charge pump
pressure must be within 275 to 400 psi (19 to 27 bar).
Test charge pressure as follows:
1. Apply all park brakes and start engine. Set engine speed
at low idle.
2. Press Enter button to go to Pressure Test and
Calibration screen from Menu screen.
3. Press Enter button to go to level 2. Use
Select buttons to show LOW PRESSURE
icon in data box.
4. Press Confirm button to start test.
5. Test starts and percent of completion is displayed in data
box.
6. When test is complete, charge pressure icon reappears
in data box.
Charge pressure levels must be within a specified range
during this test. Any pump that failed to maintain charge
pressure within a specified range is highlighted yellow.
Troubleshoot failed circuit to determine cause of fault.
