From the DOOR menu, you can establish:
- The door status (closed/locked).
- The status of the closing system microswitches.
- The values of the current absorbed by the motor during the different
door closing phases.
The door can be manually unlocked, locked and fully opened.
During the door closing and locking phases, the variations of the I motor
parameter are displayed in the digital bar at the bottom of the DOOR
screen.

SQ9 – SAFETY VALVE TEST
The SAFETY VALVE TEST allows checking the safety valve sealing by
means of a cycle bringing the chamber pressure over 2,64 bar.
The test does not provide a result regarding safety valve opening.
The operator who runs the test has to check the correct operation of the
valve, as in case of any other component in the Component Test menu.
The safety valve can open suddenly and remain open (for some seconds)
causing a significant steam outflow or it opens intermittently, causing only
a light blow. In both cases, the valve operates correctly, since it prevents
an anomalous chamber pressure rise.
The access to Safety Valve test requires a specific PIN. Contact
customerservice@scican.com to receive the Safety Valve test PIN.
The test ends with the opening of the safety valve or at a max pressure
value of 2,80 bar. It's not possible to run more than one test in sequence.
Completed the test, the display shows the maximum chamber pressure
value, reached when safety valve open.
