a) Preliminary instructions
The following are the states of the machine:

the state "off" (the device is not fed).

the state "stand-by" (the device is fed and it is out).

the state "on" (the device is fed, you/he/she has turned on and it is waiting for the start of a cycle of
operation).

the state "run" (the device is fed, you/he/she has turned on and a cycle of operation is in progress).

the state "lighting of the device", is the transition from the state "stand by" to the state "on".

the state "turning of the device" is the transition from the state "on" to the state "stand by".
If an interruption of the feeding occurs during the state "stand-by" or during the state "on", the restoration of the
feeding device will propose the same state.
If an interruption of the feeding occurs during the state "run", the restoration of the feeding device will work in
the following way:
 if a temperature blast chilling cycle or a temperature blast freezing cycle was in progress, it will be
restarted from the beginning
 if a time blast chilling cycle or a time blast freezing cycle was in progress, it will be restarted within 10
minutes of error occurrence
 if a conservation cycle was in progress, the conservation cycle will start again.
