Work Tool Parameter - Additional Information
Designed Behavior of Work Tool Parameters
Pump Flow Control Mode Parameter
Changing the "Pump Flow Control Mode" Parameter for the work tool from "Combined Flow" to "Pump #1 or Pump #2". Then changing back to "Combined Flow", the parameter will protect the tool by not allowing the second pump control spool to shift. This action keeps the pilot pressure parameter setting at
To achieve flow from the second pump, change the pressure for "Attachment Valve # X Maximum Pressure" from
Tuning High Flow Work Tools for Multi-function
Tuning a high flow work tool may be required to maximize the control of the tool during a multi-function operation. The following is a basic, high-level understanding and procedure for setting up a high flow work tool to maintain multiple operations of the Boom, Stick, Bucket, and Swing functions. This following is for "Combined Function – Electric Control" and "One-Way/One or Two Pump – Electric Control" systems only.
To start the tuning for a high flow work tool with multi-function, set the parameters for the work with the following:
Condition #1
- Attachment #1 Maximum Extend Pressure:
4000 kPa (580 psi) - Attachment #1 Maximum Retract Pressure:
4000 kPa (580 psi)
Condition #2
- Multiple Operation Maximum Extend Pilot Pressure for Attachment Valve #1:
1100 kPa (160 psi) - Multiple Operation Maximum Retract Pilot Pressure for Attachment Valve #1:
1100 kPa (160 psi)
To tune Condition #2, operate the tool along with the two most used functions to be used with the tool operation. Increase the parameter to increase tool speed. Decrease the parameter to give more oil flow to the function.
If the work tool is slow on EXTEND or RETRACT, then increase the maximum pilot pressure for EXTEND or RETRACT with that condition.
If the function is slow during the work tool EXTEND or RETRACT, then decrease the maximum pressure for EXTEND or RETRACT with that condition.
