6 SPECIAL FEATURES

6.1 Power failure:
When tension is restored after a power failure during Preparing, Wait or Shutdown, the card returns to the previous programme.
When tension is restored following a power failure with a cycle in progress, the card shuts down the machine (power failure), indicates
that the cycle has been interrupted and waits for the reset procedure to be carried out.
6.2 Reset procedure:
In the event of a Shutdown or when the stop switch is pressed with a cycle in progress, the door remains locked. To open the
door the door release sequence must be carried out from the keyboard as follows:
4. Press the STOP and START switches together and keep pressed for 3".
5. Press the short programme switch (P01) followed by the standard program key (P02)
6. The machine is reset and returns to standby.
N.B. : If the machine shutdown persists due to a fault in one of its components (e.g.: faulty probe, unsuitable levels, etc.), the door
is released and the machine remains inactive.
Seek technical assistance.

⇒7.6 Door not locked:
If when the door lock is activated the corresponding digital input of the electronic card is not activated within the set time (P15), the
