PC Valve Selected
Dither is a signal which is constantly sent to the PC valve that causes the spool to vibrate
and stay lubricated, reducing hysteresis and stiction.
Choose a setting closest to the manufacturers recommendations or use the Valve
Identification and Setting Recommendation chart in Appendix A.
If cylinder lines or cylinder are vibrating from dither, select a higher frequency and/or lower
the % amplitude.
If the valve is sticking or sluggish, select a lower dither frequency and/or a higher % amplitude.
Pk Dither - Dither Current Amplitude for PC valves only
Select the dither amplitude according
to the Valve Identification and Setting
Recommendation chart in Appendix A. Select by
rotating the right or left side multi-switch. Values
are between 0 and 25 in increments of 1%.
Dither Hz - Dither Frequency for PC valves
Select the dither frequency according
to the Valve Identification and Setting
Recommendation chart in Appendix A. Rotate
the right side multi-switch to select.
Values are 40 / 42.1 / 44.4 / 47.1 / 50 / 53.3 /
57.1 / 61.5 / 66.7 / 72.7 / 80 / 88.9 / 100 / 114.3
/ 133.3 / 160 / 200 / 266.7 / 400.
Once the proper valve is selected, perform a system communication check. Turn the box on
to confirm power. Check that the receiver is communicating properly. Check the raise/lower
and auto/manual switches. Check the remote switch functions if installed.
Check for proper hydraulic system operation. Ensure there are no leaks, excessive engine
load or pressure relief valves continually opening. Check that all circuits function properly.
NOTE: Before proceeding, warm up the hydraulic system to operating temperature.
Run the machine at operating RPM for approximately 15 minutes while cycling
the blade lift cylinder.
