What to do if my Capstone UPS has low power output?
- B
  Brittany PerezAug 16, 2025
  If your Capstone UPS exhibits low power output, start by inspecting the fuel supply. Make sure the fuel isolation valve is open and that the inlet fuel line maintains correct pressure. Check the external fuel filter to ensure it is not blocked. Also, check the inlet and exhaust airflow to ensure they are unobstructed. Finally, check ambient operating conditions and verify the expected power output due to temperature, altitude and other derating factors.

  Scott FranklinAug 19, 2025
  If your Capstone UPS unexpectedly shuts down or displays a warning, first, try restarting it. If it fails, check the fuel, air, and electrical supply. If restarting is still unsuccessful, enter the user password and reboot the system via the Display Panel. If the issue continues, cycle the power by turning off the system for 30 seconds and then turning it back on. If all else fails, note the event number on the Display Window and contact your Capstone Authorized Service Provider.

How to fix Lo-Temp/Hi-Temp/Hi-Alt error on Capstone UPS?
- R
  rebekahmcdonaldAug 31, 2025
  If your Capstone UPS displays a Lo-Temp/Hi-Temp/Hi-Alt error, it indicates that the ambient conditions are outside the design envelope of the MicroTurbine. To resolve this, adjust the room temperature, ensure adequate ventilation, and verify that the air input and exhaust are not obstructed.

What to do if Capstone UPS shows MANUAL E-STOP?
- A
  Albert PerezSep 3, 2025
  If the event display on your Capstone UPS reads MANUAL E-STOP, first address the original problem that triggered the E-Stop. Check the optional emergency stop button to verify if it has been activated. If so, reset the button, cycle power off to the MicroTurbine for 30 seconds, and then turn the power back on. The Manual E-Stop fault should then clear, and the system should resume operation. If it does not, call your Capstone Authorized Service Provider.
