16000 SERVICE/MAINTENANCE MANUAL HYDRAULIC SYSTEM
2
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.
Before replacing a pressure sender, do the
following:
• Perform the pressure sender test.
• Attach an accurate hydraulic pressure gauge
to the quick-coupler at the suspect pressure
transducer (see topic in this section).
• If the pressure appears on the gauge, bleed
the corresponding system so the gauge reads
zero pressure.
• Repeat the pressure sender test and check the
pressure on the display with the engine
running at idle — the display reading and the
gauge reading should be the same.
• Before replacing a pressure sender, check the
signal voltage at the sender. It should be 1.00
volt against ground at 0 psi.
Control Calibration
See Figure 2-20 for the following procedure.
Control calibration calculates the pump threshold command
level for all drum and swing functions. The allowable range is
5 to 25% pump command signal for the hoist pumps and 2.5
to 20% in each direction for the swing pump(s).
Perform this calibration when the following situations occur:
- A new pump or motor is installed in a drum or swing
function
- A new master node or master node software is
installed
- Operation indicates the threshold is in error,
including excessive handle motion or time required
to initiate motion or inability to start motion smoothly.
Calibrate controls using the following procedure:
1. Apply all park brakes with the switches on the control
console.
2. Start and run the engine at high idle.
3. Press the Enter button to go to the Pressure Test and
Calibration screen from the Menu screen.
4. Press the Enter button to go to level 2. Use
the Select buttons to show the CONTROL
CALIBRATION icon in the data box.
5. Press the Confirm button to start the test.
6. The Calibration starts and the percent of completion is
displayed in the data box.
7. When the calibration is complete, the control calibration
icon reappears in the 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 in yellow. Troubleshoot the failed circuit to
determine the cause of the fault.
