What to do if Dart Controller displays “LF-L”?
- G
  Gabriela LeachAug 2, 2025
  If the Dart Controller displays “LF-L” when power is applied, it's likely due to excessive noise or an abnormally low frequency in the AC line. To resolve this, review the routing of power wires to minimize electrical noise. Check for other devices sharing the same circuit that might be producing unacceptable line noise. In some cases, especially with equipment like welders, applying an AC line filter, re-routing wires, dividing circuits, using shielded cable, and properly grounding devices usually solves the problem. The unit is designed to operate with AC lines from 48-62 Hertz.

  If the Dart Controller displays “LF-H” when power is applied, the issue is likely due to excessive noise or an abnormally high frequency in the AC line. To address this, review the power wire routing in the machine to reduce electrical noise. Investigate other devices on the same circuit that could be generating unacceptable line noise. For certain applications, such as welding equipment, consider using an AC line filter, re-routing wires, dividing circuits, using shielded cable, and properly grounding devices. The unit is designed to operate with AC lines from 48-62 Hertz.

How to troubleshoot a blank display on Dart Controller?
- S
  Shannon MillsAug 14, 2025
  If the display of your Dart Controller is blank, it could be due to a lack of power or a defective unit. Verify that a voltage between 85 and 265VAC is measured between the L and N terminal block positions using a volt meter. Contact technical support for further assistance and instructions.

Why is the alarm output not working on my Dart Controller?
- F
  Frederick CaseyAug 21, 2025
  If the alarm output on your Dart Controller isn't functioning, it's likely due to incorrectly configured alarm output parameters. Review these parameters. You can test the alarm relay output by setting the Activation Condition parameter to “Always On”. When you do this, you should hear the relay click, and the NC (Normally Closed) and C (Common) terminals should become internally shorted at the terminal block.

  Laura TaylorAug 27, 2025
  If the display on your Dart Controller is dim, the display intensity parameter might be set too low. Increasing the display intensity parameter should brighten the display digits.
