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

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.

Commands
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.

The 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.
