Supply Pump for the Work Tool
Pump Flow Control ModeSet the pump to supply oil flow to the work tool using the following parameter settings for the work tool.
Select Pump 1 or Pump 2.
"ATT Valve #1" parameters are available for setting with on pump.
"ATT Valve #2" parameters are available for setting with on pump.
Pump 1 is recommended when multiple operation of work tool along with swing or stick function are frequently used.
Pump 2 is recommended when multiple operation of work tool along with bucket or boom function are frequently used.
Select Combined Flow.
"ATT Valve #1" and "ATT Valve #2" parameters are now available for setting with combined flow.Pump Flow to the Work Tool (Single Operation)
One Pump Flow using Pump 1 or Pump 2
Set the appropriate flow for the work tool to be installed by using the following parameter settings."Atch #X Flow Setting" - XXX [L/min]
Table 1
Maximum Flow Setting for One Pump Flow
320 / 323 214.5 L/min (56.7 US gpm)
Work tool open and close speed can be decreased by lowering the following parameter value.
Spool shift pressure adjustment to extend the attachment control valve."Atch #X Max Ext Press" - XXXX [kPa]
Spool shift pressure adjustment to retract the attachment control valve for two-way flow only."Atch #X Max Ret Press" - XXXX [kPa]Note: For reference, this parameter is set within the range of 800 kPa to 2000 kPa.Two Pump Flow
Set the appropriate flow for the work tool to be installed by using the following parameter settings."Atch #1 Flow Setting" - XXX [L/min]
Table 2
Maximum Flow Setting for Two Pump Flow
320 / 323 429.0 L/min (113.3 US gpm)
Work tool open and close speed can be decreased by lowering the following parameter value.
Spool shift pressure adjustment to extend the attachment control valves."Atch #1 Max Ext Press" - XXXX [kPa]"Atch #2 Max Ext Press" - XXXX [kPa]
Spool shift pressure adjustment to retract the attachment control valves for two-way flow only."Atch #1 Max Ret Press" - XXXX [kPa]"Atch #2 Max Ret Press" - XXXX [kPa]Note: For reference, this parameter is set within the range of 800 kPa to 2000 kPa. A parameter setting for spool shift pressure of 0 kPa is not made for flow from two pumps.
