(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.
3.4 Description of Displayed messages and Safety Measures
Low Heat Message is displayed and sterilization does not start if the
autoclave has not reached sterilization temperature after
heating for 50 minutes while in the Wrapped or Unwrapped
programs (80minutes in the Liquid program).
Possible causes:
♦ A clogged Air Jet (see cleaning the Air Jet sec 9.3)
♦ No power to the heating elements
♦ Low line voltage delaying heat up
Low Pres Message is displayed, fail indicator lights, and the program
is aborted if the pressure drops 4 psi (0.27Bar) below the
required sterilization pressure.
Possible causes:
♦ Insufficient water in the chamber (see Low Water message)
♦ A damaged heating element
♦ A damaged pressure transducer
