320C and 322C Excavators Attachment Hydraulic System – System 2: Default Value of Work Tool Parameters

Note: For this system, parameters that are not shown in the tables do not affect the operation of the work tool.

The table shows some of the approved Cat work tools that are used. The table lists some of the parameters that should be verified for successful operation of the work tool.

“TOOL #1 – TOOL #5” of System 2

Table 2
Default Parameters for “TOOL #1 – Tool #5” for System 2    
Message Center (Line 3)     Default Values (Line 4)     Range of Values     Increment     Description of Parameter    
    320C, 322C     325C        
“TOOL#1-001”
“Tool Program Name”    
“HAMMER 1PUMP”     “HAMMER 1PUMP”             This is the default name of “TOOL#1”. The default name can be changed. Be sure to use a good descriptive name.
When the “Tool Program Name” is entered into ET, the name of the tool must be in all uppercase letters.    
“TOOL#1-002”
“Maximum Throttle Dial”    
“10”     “10”             Parameter 002 is Enabled when parameter 003 is ON.
When Parameter 002 is Enabled and the value of the engine speed dial indicator is Greater than the value of Parameter 002, the engine speed is determined by the value of Parameter 002 when the work tool is activated.
When Parameter 002 is Enabled and the value of the engine speed dial indicator is Less than the value of Parameter 002, the engine speed is determined by the value of the engine speed dial indicator when the work tool is activated.
Parameter 002 is Disabled when Parameter 003 is OFF.
When Parameter 002 is Disabled, the engine speed is determined by the value of the engine speed dial indicator.    
“TOOL#1-003”
“Throttle Dial Flow Control”    
“ON”     “ON”             When Parameter 003 is ON, Parameter 002 is Enabled.
When Parameter 003 is OFF, Parameter 002 is Disabled.    
“TOOL#1-004”
“Underspeed Enable”    
“ENABLED”     “ENABLED”             “ENABLED” means that the controller maintains the target rpm. “DISABLED” means that the controller provides a constant torque to the pump. Constant torque is used primarily for applications with a magnet. A constant torque maintains a constant rpm for the engine and the generator.    
“TOOL#1-005”
“Two Pump Flow Combine Enable”    
“DISABLED”     “DISABLED”             “ENABLED” means two-pump flow. “DISABLED” means one-pump flow.    
“TOOL#1-101”
“Attachment Valve #1 Flow Setting”    
“160.0”     “180.0”     0 to 400 L/min (0 to 105.7 US gpm)     5 L/min (1.3 US gpm)     This is the flow that is required to operate a specific work tool. This value is specified by the manufacturer of the work tool.    
“TOOL#1-102”
“Attachment Valve #1 Multi-Oper. Additional flow”    
“0.0”     “0.0”     0 to 400 L/min (0 to 105.7 US gpm)     5 L/min (1.3 US gpm)     Use caution when this parameter is set. The excess flow that is not required by the additional operation will be diverted to the work tool. Possible damage to the work tool can result.
Parameter 102 is the additional flow from the pumps when another control valve on the main control valve shifts during the operation of the work tool. The additional flow enables the work tool to operate at a constant flow during the operation of the other functions.    
“TOOL#1-103”
“Tool Program Valve #1 Nominal Pressure”    
“16000”     “16000”     0 to 40000 kPa (0 to 5800 psi)     100 kPa (14.5 psi)     This is the desired operating pressure for the specific work tool. This value is the operating pressure for the tool plus 2000 kPa. This method is used in order to account for line losses. The “psi”setting is specified by the manufacturer of the work tool.
