What to do if the voltage is high and uncontrollable with the voltage adjust rheostat on my Basler Controller?
- J
  James WillisAug 12, 2025
  If the voltage of your Basler Controller is high and uncontrollable even when using the voltage adjust rheostat, try the following: First, repair any damaged wiring. Then, ensure the system is set to AUTO. If the issue persists, replace the Voltage Adjust Potentiometer or the relay. Reconnect to the proper tap. If none of these steps work, it may be necessary to replace or repair the voltage regulator.

How to fix a Basler Controller when the voltage doesn't build up to the rated value?
- J
  Joseph StevensAug 17, 2025
  If the voltage of your Basler Controller does not build up to the rated value, you can try the following: * Flash the generator field. * Close the switch. * Adjust the speed. * Repair any damaged wiring. * Reconnect the exciter. Also, check and reconnect the wiring properly, remove any shorts and repair the wiring, shed excess load, change taps for the correct nominal voltage, and if necessary, replace or repair the voltage regulator. You might also need to repair the wiring and/or adjust/repair the regulator.

  If the voltage of your Basler Controller is high but controllable with the voltage adjust rheostat, you can try the following: ensure that you reconnect to the proper tap, adjust the potentiometer, or replace the potentiometer with one of the proper value. Also, ensure that you reconnect properly, reconnect for three-phase sensing, and reconnect the voltmeter properly. If the issue still persists, consider replacing or repairing the voltage regulator.

What to do if voltage builds up until relay actuates, then decays on a Basler Controller?
- J
  Julie MartinezAug 30, 2025
  If the voltage builds up until the relay actuates and then decays in your Basler Controller, you can try repairing the circuit/wiring or replacing the rheostat. If neither of these actions resolves the issue, consider replacing or repairing the voltage regulator.

How to obtain reactive droop compensation for parallel generators on a Basler Controller?
- A
  Alejandra HarringtonSep 4, 2025
  If you cannot obtain reactive droop compensation for parallel generators using your Basler Controller, try the following: Adjust R25 to obtain the required droop and set the switch to PARALLEL. If these steps do not work, replace the switch and/or repair the wiring. If the problem persists, it may be necessary to replace or repair the voltage regulator.
