The System Circuit Breaker protects main input power to the Compressor
pump and module. The circuit breaker positions are labeled ON (1), which
is in the UP position, and OFF (0), which is in the DOWN position.
NOTE: The phase monitor within the Compressor will cause the system
circuit breaker to open when input power phases are incorrect.
The Control Circuit Breaker provides current overload protection for all
internal components of the Compressor except the Compressor motor. The
Compressor motor is protected by a separate overload protector. The
Control Circuit Breaker opens automatically and must be reset manually.
The Power On Indicator illuminates when the system circuit breaker is
placed in the ON position. The Compressor pump is energized when the
power indicator is illuminated and the elapsed time meter records system
operation time.
The Gas Charge Flared Fitting is used to connect a 99.999% pure helium
supply to the Compressor when helium charging is required. The fitting
has a 45 º flare and 7/16 in. x 20 threads/inch.
Refer to Section 5 - Maintenance for information on adding helium to the
Compressor.
The Helium Pressure Gauge indicates system static helium charge pressure
when the Compressor and cryopumps are OFF and Compressor suction or
inlet pressure when the Compressor is ON. Refer to Table 4-1 for the
appropriate static helium charge pressure.
The Power Inlet is used to connect your power cable to the Compressor.
Refer to Section 3 - Installation for information on power cable
installation.
