      Why is the LCD display screen blank on a Micrologic Power or Harmonic type trip unit on a Powerpact P frame, R frame, or Masterpact circuit breaker?

      Why is the display blank on the trip unit?

      Product Line:
      Powerpact P frame, Powerpact R Frame, Masterpact NT, Masterpact NW

      Applied to Powerpact and Masterpact breakers with trip units with LCD displays.

      Need to power display of the trip unit without external power supply.

      The LCD display on a Micrologic P or H trip unit will be blank unless the trip unit is energized.  Energization requires one of the following sets of conditions:
      1. The trip unit is energized by an external 24 Vdc applied to terminals F1-F2 (F1 negative-F2 positive)
      2. The trip unit is energized by an FFTK or HHTK test kit
      3. There is at least 100 V between two phases, AND the load reaches approximately 20% of the breaker's rated current.
      • Note that the display will not power up with primary injection testing unless one of the conditions in bullet 1 above is met.
      • Note that Ammeter trip units do not require external power and the display will come on with sufficient current flow alone.
      See the following bulletins for more information on these trip units.

      How can you copy a old ATV31 program into a new ATV312 drive?

      Can you transfer an ATV31 program into a new ATV312?

      Product Line:
      Altivar ATV312, ATV31


      Needs to use the old file from his ATV31 and put that program into his new ATV312 drive.

      Yes, you can copy the old ATV31 file into the new ATV312 drive.
      You will need to set up your new ATV312 to act like a old ATV31 by setting the  ArE parameter to 31E or 31A.
      The differences are as follows.
      31A has the knob on the face of the old ATV31 drive.
      31E does not have the knob only the 4 buttons on the face of the drive.
      To copy the old program from the ATV31 into the new ATV312 drive you will need the original ATV31 remote keypad, Powersuite software V2.6 or the Multiloader.

      See the attached pdf document for notes.
