Job Card CHK A001 - Boot/Init and Shutdown
6 PROCEDURE
This Job Card provides check lists for confirmation of the correct operation of power up and power down
sequences, and for the steady state conditions to be expected with power on or off.
• Refer to the Power Supply Schematic diagram overleaf for an overview of power connections.
• In normal operation, system power switches are used as follows:
Power comes from the hospital supply circuit breaker to the Generator Circuit Breaker and to a circuit
breaker in the MDR (the Main Distribution Rack at the top of the Generator Cabinet), in parallel.
Both circuit breakers are normally left ON.
All subsystem power switches (items in the Control Station, Conditioner, etc.) are normally left ON.
The system is normally switched ON using the ON switch (I) on the Gantry Console.
The system is normally switched OFF by clicking the System Off button in the Browser win-
dow. When switching off, wait for complete system and UPS shut down (about two minutes).
The Gantry and Generator can be switched OFF without affecting components in the Control Station
by pressing the OFF switch (STOP) on the Gantry Console.
