Controls Calibration
A controls calibration calculates the pump threshold
command level for the swing and accessory pump controls.
Perform this calibration when:
• A new swing pump, motor, or control coil is installed.
• A new accessory pump or control coil is installed.
• A new master node or master node software is installed.
• Operation indicates threshold is in error:
- Excessive handle motion or time is required to
initiate swing motion.
- Inability to start swing motion smoothly.
To perform the controls calibration:
1. Apply all park brakes using the switches on the control
console.
2. Start and run engine at high idle.
3. At the display, navigate to test screen 1 or and run the
calibration test (Figure 2-30 on page 2-33
).
4. Verify no icons are highlighted in yellow in either test
screen. Troubleshoot failed circuits to determine the
fault cause.
5. Verify no pumps are highlighted in yellow. Troubleshoot
failed circuits to determine the fault cause.
