Initial Setup

To get started with the AccuPulse 4.0 tool, follow the instructions on page 5 of the user manual.
AccuPulse 4.0 Transducerized Mechanical Pulse Tools

• Initial tool setup will require running down the same joint more than once In the Adjust Torque Offset to get the Initial joint signature to match the audit torque. That joint signature will be unique for that application.
• It’s recommended to use new hardware for each rundown during Adjusting Torque Offset setup.
• After each rundown connect the tool to read the data and perform the offset calculation.
• On multi-fastener setup, especially with mean shift characteristics, select the bolt with medium to soft joint, not the hardest joint for initial setup. This gives the best average results across the batch.
• Items needed for setup:
• Digital torque wrench or rotary transducer for static audit only
• Do Not run rotary inline with tool
• PC with software and cable
• The tool will contain the last parameter written to the tool if it’s been used before or default values if it’s a new tool
• Under the Parameter tab to select Read From Connected Tool to see current tool parameters to edit or save.
• Copy Parameter to save the tools parameter if you don’t want to lose that parameter
• Create New to setup for a new application
• Parameters will be archived in the parameter list

New Parameter Setup

1. Select “Create New” to start a new assembly with the default offset values.
2. A popup window will appear to name the parameter. Provide a name and select “add”.
3. Select “Adjust Torque Offset”. An “Adjust Torque Offset” window will pop up.
4. Choose the socket length, including the extension.
5. Type in the target torque for the Shut-off torque.
6. Select “Continue Offset” to store the value in the tool.
7. Unplug the tool and rundown the fastener.
8. Use a digital torque wrench to check the residual torque.

Please refer to page 7 of the user manual for more detailed instructions on adjusting the torque offset.

Getting Started

• Download and unzip the software from the Link below
• Open Tool Manager software folder
• Follow the path below to the Install.exe and select
• When the tool manager installation opens, select next and follow the onscreen instructions
  Software link: https://na.panasonic.com/us/support/accupulse-40-resources
  

Connecting the Tool

• • Open Tool Manager software, plug the tool into the USB if you haven’t already
  • Pull the trigger to wake the tool if the tool is not already awake
  • A Pair Tool screen will popup. Press Pair Tool button
  • The paired tool will highlight in blue in the left column. The tool list will include all tools previously connected tools, up to 9 tools

New Parameter Setup

1. Select Create New Always start a new assembly with Create New and default offset values
2. A Popup window appears to name the Parameter, then select add
3. Select Adjust Torque Offset. A “Adjust Torque Offset” window will pop up and you will begin the process of matching the tool torque algorithm to the audit torque

Default Offset Values

Default Offset Values

Tool| Slope| Intercept| Unit of Measure| Tool| Slope| Intercept| Unit of Measure
MH1| 25Nm| 5| Nm| MH2| 55| 25| Nm
221.24| 44.25| in.lbs| 486.73| 221.24| in.lbs
18.44| 3.69| ft.lbs| 40.56| 18.44| ft.lbs

• If the assembly has multiple fasteners and mean shift issues, use the softer to middle joint to initially setup the tool.
• Use the minimum output mode to determine the fastener’s minimum torque discussed on page 8

Adjust Torque Offset

matching the tool torque algorithm to the audit torque

1.  Choose the socket length including the extension

2. Type in the target torque for Shut-off torque

3. Continue Offset to store the value in the tool

4. Unplug the tool and rundown the fastener

5. Use a digital torque wrench to check the residual torque for the Audit torque Value required for step 8

6. Plug tool back in

7. Select Acquire to upload the tool rundown data.

8. Input the Audit Torque Value from the static audit

9. Select Check to calculate the new offsets
   The offset slope and intercept will change, adjusting the tool torque signature to the audit torque

10. Continue Offset to write the new values to the tool.

11. Repeat from step 4 until the % column and offset value Turn green indicating torque values are within 5%

12. Update & Exit when 5% is met

Note: If the tool is not shutting Off

• Harder joints and higher torque may cause the tool to not shut off
• Go back to the parameter page
• Increase Offset slope by 5 incrementally (55-60) for a MH2.
• Increase Offset Slope by 3 incrementally (25-28) for MH1
• Go back to Adjust Torque Offset and try the procedure again

Minimum Output Mode

If you receive unexpected results during the Adjust Torque Offset or cannot achieve the lowest torque needed, use the “Minimum Output Mode” to qualify the bolt.
Test the bolts for minimum torque possible. Follow below

1. Change to 1500 rpm on the parameter page to get lower torque if required
2. Select the socket extension length
3. Select “Minimum Output Mode”
4. Select “OK”
5. Unplug the tool and run each bolt down that you want to test
6. Do a static audit of each bolt
   That audit will be the minimum torque capable for that tool to bolt
   *After the Minimum Offset Mode has been made or not required, uncheck the Minimum Offset Mode and continue to the next slide
   Note: If you setup on bolts that cannot reach the minimum torque required without testing, you will get unreliable torque results
   Use the procedure described and stay within the torque-to-bolt range and the tool will be very reliable

Saving Parameters

After adjusting torque offset you will close and return to this main screen. You can see below the new offset value As a part of the unique algorithm for that assembly

• Write to the tool will erase the previous parameter in the tool and replace it with the highlighted parameter selected from Parameter column
• Save Parameter will overwrite and save changes that are made to the selected parameter
• Copy Parameter copies the selected parameter. A popup window will prompt for a name and any comments you want to add to the copy. The new parameter will be listed under the Parameter tab
• Export highlighted parameter to a .csv file to archive saved parameters to a file. The saved files are used for uploading to a controller or imported for stand alone use

Settings and Limits Explanation

• Mode setting turns wireless communication on/off.

• Wireless Communication enable wireless communication for pairing to the controller

• Stand Alone is no wireless communication.

• Shut-off torque is the target torque

• Upper and lower limits for minimum and maximum allowable torque for OK/NOK. If the final rundown torque is above or below the limits, the tool will display NOK

• Offset is automatic offset adjustment during Adjust Torque Offset procedure. Alignment of tool torque to Static torque

• Default will change the offset values to default

• No Load speed rpm speed before the tool begins to pulse or see a load. Selectable from 1500 to 2300, in 100 rpm increments

• Variable speed is rpm speed before load depending on depth the trigger is pulled
