5.3 Description of Displayed Messages and Safety Measures
Low Temp. Message is displayed, fail indicator lights and cycle is
aborted, if the temperature drops for more than
5 seconds 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 60 minutes (slow exhaust program), and 30
minutes for all other programs.
High Temp. Message is displayed, fail indicator lights and the program
is aborted:
If the temperature rises 3C above the required
sterilization temperature during the sterilization
cycle or,
If the temperature sensor is damaged, this message
appears during the HEAT stage.
Low Pres. Message is displayed, fail indicator lights, and the
program is aborted if the pressure drops for more than 5
seconds below the pressure correlated to the required
sterilization temperature.
High Pres. This message is displayed, fail indicator is lit and the
program is aborted, if pressure rises above the pressure
correlated to the sterilization temperature +3
ºC- for more
than 5 seconds.
Man. Stop Message is displayed and the FAIL indicator lights after
the STOP key is pressed for longer than 1 second.
Power Dn If a power failure occurred during the STERILIZATION
stage, but the temperature has not dropped below the
sterilization temperature. When it resumes, the system
automatically readjusts, this message is displayed for
several seconds, the printer prints POWER DN. If
temperature falls below the sterilization temperature the
cycle is aborted on “LOW TEMP”.
If the power failure occurs during the heat stage, when
power resumes the system returns to the HEAT stage, the
message POWER DN is displayed and printed.
If a power failure occurred during Program 6 (slow121),
the system does not allow fast exhaust (as exhaust valve is
normally closed) during a power failure or when power is
back on.
If a power failure occurs during the HEAT stage, heating
resumes (provided there is enough water in the chamber).
If not, the cycle aborts.
Dry and exhaust stages automatically resume operation
once the power is back on.
