Pretrip Inspection Test (PTI)

To properly perform a PTI (Pretrip Inspection Test) on units equipped with a SG+ controller, do not apply a load to the alternator.

  1. Start the unit.

  2. Initiate an automatic PTI:

    Note Correct all existing alarm conditions and clear the alarm codes before performing a PTI.
    • Press the ENTER key or the ESCAPE key to enter the Main Menu, if necessary.

    • Press the UP or DOWN key to scroll up or down through the Main Menu to the Commands Menu.

    • Press the ENTER key to enter the Commands Menu.

    • The PTI submenu will be displayed.

    • Press the ENTER key to start the PTI.

  3. When the PTI is complete, the test ends automatically and the controller display shows “PTI PASSED (or FAILED) - REBOOT”. Turn the On/Off Switch Off and back On to reboot and return the unit to normal operation.

  4. If an operating problem occurs during the PTI, view and correct any alarms or messages. Then acknowledge the alarms or messages and repeat the PTI.

    Note Acknowledge the alarms or messages ONLY after the alarm codes are documented and problems repaired.
