All Capstone Model C30 Stationary MicroTurbine Systems.


Version 4.93 software has been released to support the Model C30 MicroTurbine systems. This release offers the following major changes:

1. System Improvements:

♦ A new display item has been added for setting and displaying user’s power demand (PWRDMD). This value is different from the Stored Power Demand (PWRDST) value that was already being displayed.

♦ Allows MicroTurbines without a battery (GC-only units) to be compatible with a Capstone Power Server.

♦ Allows user to enable/disable the daylight savings time feature on the real-time clock.

♦ Allows a MultiPac Disabled MicroTurbine (number greater than 1) to accept serial commands from MicroTurbine Number 1.

♦ Changed the default settings of the UCB Output Relays to be set for the new function “Unused” and configured to be “Active Open”.

♦ Allows a MicroTurbine to auto-restart after a 5000 Fuel Subsystem fault with SPV PIC software version 2.14 and higher. The SPV Part Numbers shipped with this software are:

503044-103 509224-202 513321-101

2. Liquid Fuel Systems:

Model C30 Software Version 4.93 Release Notes

♦ Injector #2 clogged fault (16019 LF INJ2 CLGD) and injector #3 clogged fault (16020 LF INJ3 CLGD) are treated as warning faults and the system is allowed to run with the good injectors. However, if both injectors #2 and #3 are clogged (16021 LF MULTI INJ CLGD), or if injector #1 is clogged (16018 LF INJ1 CLGD), the system will always transition to the Fault state.

♦ A new fatal fault “5022 NO AIR ASST DEV” is reported if the RFC is not locked when transitioning to Lightoff.
