APOLLO MISSION SIMULATOR INSTRUCTOR HANDBOOK 1.2.1 UTILITY POWER

There is a set of bus bars for utility power routed independently from the rest of the system. This power supplies all of the convenience outlets located throughout the AMS. It also supplies the utility 26-volt power used to operate lights and relays which should be enabled even when the rest of the system is off, for example, cabinet overhead lights and relays, power status lights, and emergency off lights.

1.2.2 SIMULATOR POWER

The simulator power, except of utility power is routed through a main circuit breaker, which can disconnect the entire simulator. After the main circuit breaker are the main power buses from which the power is divided into six groups.


 * Life support
 * 400-cycle motor generator
 * Computer complex
 * Data conversion equipment
 * Peripheral
 * Visual

Each group has four lines coming from the main power buses. There is a circuit breaker and a contactor in series for each group. Switching of power to these groups is accomplished by the sequencing circuitry, which operates in two modes controlled by switch lights on the main power panel located in cabinet 33. 1-2
