Troubleshooting
WARNING
The MicroTurbine system produces and contains high voltage. High
voltage can injure or kill. Obey all safety procedures when you work
around electrical equipment.
Only Capstone Authorized Service
Providers are permitted access to the inside of the enclosure.
This section details basic troubleshooting procedures and steps that the user can perform
on the Capstone MicroTurbine without accessing the inside of the enclosure. Only
Capstone Authorized Service Providers are permitted access to the inside of the
enclosure.
Incidents
The MicroTurbine continuously monitors a wide variety of parameters both internal and
external to the system. An
incident
occurs whenever a measured parameter falls outside
prescribed limits. Incidents include (but are not limited to) low fuel pressure, utility
interruptions, and utility over voltages.
Incident System Severity Levels
When the system detects an incident, it may take one of several actions, depending on the
system severity level (SSL). Actions range from simply noting the occurrence and
continuing to operate, to immediate shutdown of the system. The action taken depends
upon the severity of the incident. The system will attempt a restart only if the severity of
the incident will allow it.
Depending on the parameter and the magnitude of the incident, the event is classified as
either a warning or a fault.
A
warning incident
is a condition that is outside normal operating parameters, but which
does not require a system shut down.
A
fault incident
is a condition under which the system shuts down to prevent possible
damage to the MicroTurbine or unsafe operating conditions.
Incident Display Format
When an incident occurs, the Display Panel displays a fault description (e.g.,
Internal
Fault
) and the fault code (e.g.,
10214
). This incident message appears on line three of the
System State Fault Status submenu of the Unit Data menu (refer to page 52) as shown in
the following example.
Unit Data 4/4
System STAND BY 1/20
Internal Fault 10214
