Reset Flow (HQ-coordinated):

  3. Provide the Query Code generated by the tool to HQ.

  4. HQ issues an Erase Code.

  5. Enter the Erase Code in the tool to complete the reset.

    ⚠ Keep the tool open during this process — closing it invalidates the Query Code.

If password reset procedure fails:

  1. Uninstall and reinstall the Service Tool software.

  2. Navigate to:
    Tools → Drop DB → DropVRFDB.bat

    1. Complete new registration.

    2. The Master Password will also be emailed upon registration.

    3. Enter this password within the app to activate.

9. Software License Recovery

For PC-based tools (e.g., Service Tool or ASGXZ1 License Manager):

  • Press Ctrl + Alt + Refresh within the License Manager window under the “Move License” tab to regenerate the key.

  • Send the exported file to HQ for release key issuance (one-time per license).

10. TPC Software (UTY-PTGXA) Reactivation

Use case: When replacing a damaged TPC unit running the electricity charge apportionment software.

  1. Provide the MAC address of the new TPC to HQ.

  2. HQ will generate a special password tied to that MAC address.

  3. Connect the existing WUK (license key) to the new TPC.

  4. Enter the special password on the installer setting password verification screen.

  5. The software license will automatically transfer to the new TPC.

Ensure the TPC runs the latest version (E045V03P00L02) to avoid activation errors.
