Fuel Gas Booster Electrical Connections - Capstone 60 MicroTurbine

This Service Bulletin complements the Application Notes 512001 for installing the Copeland Fuel Gas Booster with the Capstone 60 MicroTurbine.

Affected

All Capstone 60 MicroTurbine systems that operate with the Copeland Fuel Gas Booster powered through the MicroTurbine electronics DC bus.

Summary

Capstone has noticed an incident of Pre-charge Board failures when operating with the Copeland Fuel Gas Booster. Failure can occur by enabling the Copeland Fuel Gas Booster prior to the MicroTurbine making direct connection between its DC bus and a power source such as the grid. In standby operation, the DC bus is only connected to the grid via resistors on the Pre-charge Board. Operating the Copeland Fuel Gas Booster in this state will cause excessive power draw through the Pre-charge Board leading to failure.

When installing the Fuel Gas Booster, the electrical connections between the Fuel Gas Booster and the MicroTurbine must be performed in the manner outlined below to avoid failure.

1. Ensure that there are no electrical connections between the MicroTurbine and the Fuel Gas Booster.

2. Power up the MicroTurbine.

3. Program the UCB relays per the instructions in the Application Notes 512001.

4. Power down the MicroTurbine.

5. Connect the Fuel Gas Booster control terminals to the correctly programmed UCB relays.

6. Connect the Fuel Gas Booster high voltage terminals to the MicroTurbine DC bus.

7. Power up the MicroTurbine and operate the system per the instructions in the

Application Notes 512001 and the MicroTurbine System Manual.
