What to do if the Endress+Hauser HART Proline t-mass I 300 local display is dark and there are no output signals?
- D
  Daniel BrooksAug 5, 2025
  If the local display is dark and there are no output signals, it could be due to several reasons: * The supply voltage may not match the specifications on the nameplate. Ensure you apply the correct supply voltage. * The polarity of the supply voltage could be incorrect. Correct the polarity. * There might be a poor connection between connecting cables and terminals. Check the connection of the cables and correct if necessary. * Terminals may not be correctly plugged into the I/O or main electronics module. Check the terminals. * The I/O or main electronics module could be defective. Consider ordering a spare part.

Why is the Endress+Hauser HART Proline t-mass I 300 Measuring Instruments local display dark but signal output is within the valid range?
- P
  Patricia SparksAug 12, 2025
  If the local display is dark, but the signal output is within the valid range, it could be due to a few reasons: * The display might be set too bright or too dark. You can set the display brighter by simultaneously pressing the indicated buttons, or darker by pressing the other indicated buttons. * The cable of the display module might not be plugged in correctly. Ensure the plug is correctly inserted into the main electronics module and display module. * The display module itself could be defective. In this case, consider ordering a spare part.
