Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 Service Bulletin SB0066: Model C30 Software Version 5.01 Release Notes 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. Features Included from Version 4.98 1. Added ability to change polarity on Fault Inputs for use with relays. Prior to this change, to trigger an external fault input, the Fault input terminals had to be closed (shorted). This continues to be the default polarity. With this change, the user is allowed to set the polarity so an open circuit between the terminals would indicate an active fault, i.e., ACTIVE OPEN. To support this setting, a new display setting, OPEN/CLOSED, is added to Fault Input 1 and Fault Input 2 submenus. The value can also be set through the RS232 command INPFLT. The command has been updated such that there is an additional parameter at its end that is used to specify the value for the polarity setting (Ø for Active Open, 1 for Active Closed). For example, the user can program Fault Input 1 using the following command: INPFLT = 1,1,3,12Ø,Ø This command translates into: Fault Input 1, Enabled, SSL3, 12 seconds, and ACTIVE OPEN (Normally Closed). 450043-001 Rev A (June 2004) Page 2 of 4 This information is proprietary to Capstone Turbine Corporation.
