Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 Service Bulletin SB0066: Model C30 Software Version 5.02 Release Notes 5. In the SPV position calculation, the difference between the pressure upstream and the pressure downstream (delta P) is now limited to positive or null values (previously, it also produced negative values). The improvement results in the correct behavior of the valve and ability to light off. 6. Updated code to allow for Protective Relay Under Voltage Time and Over Voltage Time to be adjusted to as low as 0.09 second (previously, the limit was 0.3 second), as requested by certain utility establishments. 7. Changed LOW DCBUS VOLT (6027) to declare at 475VDC to satisfy low grid voltage applications. The DC bus low voltage limit was introduced in version 4.93 software release, but was set too high. As a result, nuisance faults associated with the limit were latched under specific applications. 8. 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. Requires the use of PowerServer software version 2.20 or later. 9. Updated code so that on a MultiPac system, the user-set power demand as well as the actual derated power demand assigned to any MicroTurbine can be viewed on the display panel. 10. 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. 11. Added °C units to the TET value in the Event Log display menu. Features Included from Version 4.99 1. Updated code so after the injector switch is complete, the igniter is turned off. 2. Fixed power oscillations at 19, 21, and 23 kW. 3. Added a new SPV25 valve position scheme for 2-point calibrated valves. 450043-001 Rev B (June 2004) Page 2 of 5 This information is proprietary to Capstone Turbine Corporation.
