GLOBAL OFF which is a state of the power supply in which the entire system (including CONTROL/ELECTRONICS and any AUXILIARY services) is switched off through a main circuit breaker. Manual action is required to transition the power supply from the GLOBAL OFF condition into the OFF state: a transition from the GLOBAL OFF condition into any other state is not permitted.

ConditionsA DEFECT is a condition which will cause an interlock.A NOMINAL condition is one in which there are no interlocks and hence no DEFECTs.

CommandsCommands
A Command is defined as something that is recognized by the Power Supply and drives the Power Supply between two states. The Commands for the Power Supply are:
OFF: If no DEFECT is present, the power supply is transitioned to the OFF state. In this state the outputs of the AC power sections of the system are switched off through a magnetically actuated circuit breaker. CONTROL/ELECTRONICS and any AUXILIARY services are powered on.
STANDBY: If no DEFECT is present, the power supply is transitioned to the STANDBY state. In this state the outputs of the AC power sections of the system are energized, and ALL power semiconductors are in the off-state (i.e. zero current in the load). Only the triggers for the switched elements of the power supply are inhibited.
ON: If no DEFECT is present, the power supply is transitioned to the ON state. In this state all circuits are energized and the trigger gates are enabled. The power supply will pulse upon the receipt of appropriate timing signals.
RESET: After all DEFECTs are cleared, and a RESET command is issued, the power supply will transition to the OFF state. Accidental depression of the RESET button must not result in any hazardous operation.

ImagThe MedAustron Beam Delivery control system will provide:•The state commands and the value of the magnet current reference for the present cycle;•The necessary timing pulses (START and STOP) to drive the power supply;
To reduce the probability that the PKC will receive an incorrect command to remain in the on-state (e.g. due to a faulty trigger card), a timing protocol using two independent timing inputs is envisaged.
These two inputs would be “ANDed” in the LCS of the PKC to derive the required trigger state: a HIGH level on BOTH input lines represents a START signal, whereas a LOW level on either or both lines, represents a STOP signal. The “AND” unit must be failsafe, i.e. if it or its power supply fails it must give a low level output.
