Tuttnauer EA - Description of the Display Panel; Display Messages and Safety Measures Description

1.6 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 current pressure within the
chamber. This happens whether the system is running a programme or not (provided the
main power switch is turned on).
The three other sections are designated to show the parameters of the selected programme.
or operating messages. When the system is running a sterilization programme, 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 programme will be displayed above the DRY TIME key.
If the programme aborts as a result of a programme check, (high. low pressure or
temperature etc.) or a manual STOP command, the message will be displayed on the left
side of the screen. When a message is displayed, pressing any key will erase the message
and redisplay the selected programme screen.
When the system is running a programme, the screen will display 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.
1.7 DESCRIPTION OF DISPLAYED MESSAGES AND SAFETY MEASURES
LOAD NO. Message is displayed, when the START key is pressed; performs a
count of executed cycles..
LOW TEMP. Message is displayed, fail indicator lights and cycle 1s
aborted, if the temperature drops below the required sterilization
temperature.
LOW HEAT Message is displayed and sterilization does not start if the autoclave
has not reached sterilization temperature after heating for 80 minutes
(liquid program), and 50 minutes for all other programs.
HIGH TEMP Message is displayed, fail indicator lights and programme is aborted:
9 If the temperature rises to 3°C (6°F) above the required sterilization
temperature during the sterilization cycle or,
9 If the temperature sensor is damaged, this message will appear during
the HEAT stage.
LOW PRES Message is displayed, fail indicator lights, and the programme is
aborted if the pressure drops to 4PSI (0.27Bar) below the pressure
correlated to the required sterilization pressure.
