Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 Service Bulletin SB0064: Model C60 Software Version 4.22 Release Notes Version 4.21 Updates 1. Auto Restart Delay is ignored even in presence of other faults, when going through a Mode Transition from GC to SA or SA to GC. The Mode Transition fault (7003) is perceived to be different from any other fatal fault that causes the MicroTurbine to restart. The restart in this case is seen to be a necessary action for dual mode functionality. 2. The Auto-Restart Delay is now ignored when a manual start is initiated with Auto-Restart set to NO. 3. Fixed a bug that caused incorrect Auto Restart Delays to be used during a Mode transition in a dual mode setup (GC delay was used when unit restarted in SA mode and vice versa). 4. Changed PM data update logic, so after an upgrade from any version later than v3.91, all PM data variables (added since v3.91) will be set to their new default values. 5. Fixed a bug that caused an update from v4.02 to v4.21 to lose many Frame PM and Frame EEPROM Checksum (5012) settings. 6. Updated code to allow Protective Relay Under Voltage Time and Over Voltage Time to be adjusted as low as 0.09 second (previously the limit was 0.3 second), as requested by certain utility establishments. 7. Fixed a bug that caused Protective Relay Frequency settings to be set inaccurately. For example, 59.1 Hz reverted to 59.0 Hz, 59.3 Hz to 59.2 Hz, etc. This was a scaling issue and was corrected to enable frequencies to be set accurately. Features Included from Version 4.10 1. Version 4.10 software was released for the Model C60 ICHP system. Refer to Service Bulletin SB0062 for details. Features Included from Version 4.04 1. Modified TET algorithm to match the 2-point calibrated valves to the new SPV25 valve. 2. Fixed a bug that caused GC MultiPac Subordinate systems to fail to lock the fuel device, when a 2-point calibrated SPV25 valve with a max position of greater than 80% was installed. A software bug in the "Max SPV Position" algorithm did not provide the acknowledgment signal to the calling function. The calling function would continue to retry indefinitely, thus congesting the SPI communication bus. This would not allow the Subordinate MicroTurbine to properly transition into the MultiPac Subordinate state and prohibit the Subordinate system from receiving a Start command from the Master MicroTurbine. Features Included from Version 4.03 1. Added a fix to handle nuisance CHP Self-Test-Fail fault (17002). 450038-001 Rev B (June 2004) Page 2 of 5 This information is proprietary to Capstone Turbine Corporation.
