(13) STOP
This key issues the only command accepted by the system
during the running of a program. Pressing this key for over 1
second causes the program to immediately cease running and
enters the EXHAUST stage, at the end of which the “MAN.
STOP” message will be displayed. This key has no function
when the system is not in operation and its only use is to
manually stop a cycle. In normal working conditions on
completion, the system automatically terminates the cycle,
without use of this key.
The STOP key does not function in EXH stage.
3.3 Description of the Display Panel
The display is comprised of 16 characters in one row and is divided into
4 sections.
The first section to the right, continuously shows the actual pressure
within the chamber. This happens whether the system is running a
program or not (provided the main power switch is turned on).
The three other sections are designated to show the parameters of the
selected program, or operating messages. When the system is running a
sterilization program, the sterilization temperature will be displayed
above the
TEMP key. Sterilization time will be displayed above the
STE. TIME key and the drying time for the selected program will be
displayed above the DRY TIME key.
If the program is aborted as a result of parameters exceeding the
controlled limits (high, low pressure or temperature etc.) or a manual
STOP command, a message is displayed on the left side of the screen.
When a message is displayed, pressing any key erases the message and
redisplays the selected program screen.
When the system is running a program, the screen displays the current
temperature within the chamber and the remaining time for sterilization
or drying. The current real pressure inside the chamber is always
displayed on the screen.

is aborted if the pressure drops 4 psi (0.27Bar) below the
required sterilization pressure.
