Fuel
The user should initially check the fuel supply to the MicroTurbine. Verify that the shut off
valve is open. Ensure the line has the correct fuel pressure. Check the optional external
filter to ensure that it is not blocked. If the problem persists, call your Capstone Authorized
Service Provider.
Grid
This event is likely to be due to an electric utility grid disturbance. Check all breakers and
fuses to ensure they are not tripped before troubleshooting. The Hybrid UPS system will
continue to supply power to the critical load while operating in Emergency Mode, even if
the utility power source is unavailable. It will also automatically reconnect to the utility
source when the utility power returns to a stable condition and the Hybrid UPS system has
transitioned through its utility reconnect delay. If the system does not reconnect to the
utility power source after utility power has been restored, call your Capstone Authorized
Service Provider.
Lo-Temp/Hi-Temp/Hi-Alt
Generally, these incidents are due to ambient conditions that are outside the design
envelope of the MicroTurbine. Possible solutions would be to adjust the room temperature,
ensure that adequate ventilation is provided, and verify that the air input and exhaust are
not obstructed. Continued operation under these conditions may affect operation and
cause damage to the MicroTurbine.
E-Stop
If the event display reads
MANUAL E-STOP
, fix the original problem that initiated the
E-Stop, as this fault must be cleared before it is safe to resume operation. Next, check the
optional emergency stop button and verify that it has been activated. If it has, reset the
button, cycle power off to the MicroTurbine for 30 seconds, and turn the power back on.
The Manual E-Stop fault should clear, and the system should resume operation. If it does
not, call your Capstone Authorized Service Provider.
User Conn (User Connection)
User Connection incidents can be due to incorrect Grid Connect / Stand Alone settings,
mode transition faults when in Dual Mode operation, or to indicate a possible problem with
external equipment connected to the MicroTurbine, such as the Gas Pack accessory.
