Door Unlock Message is displayed and the DOOR CLOSED LED
indicator remains unlit, if the door is improperly closed
when the START button is pressed. If the door accidentally
opens during any stage of the cycle, the same message
appears, the DOOR CLOSED LED indicator will turn off,
and the system reacts as if the STOP key was pressed.
High Pres. Message is displayed, fail indicator lights up, and the
program is aborted if the pressure rises 10psi (0.6Bar)
above the required sterilization pressure.
Possible causes:
♦ A damaged solid state relay
♦ A damaged heating element
Man. Stop Message will be displayed and the FAIL indicator will
light after the STOP key is pressed for longer than 1 second.
Add Water Message is displayed and the respective red LED indicates
insufficient water in the water RESERVOIR. After water is
added to the reservoir, the START button must be pressed
again in order to start the required sterilization cycle.
Water Inlet During the automatic water fill, the message WATER
INLET is displayed, as information to the operator.
Power Dn. If a power failure occurred during the running of a cycle,
when power resumes a POWER DN message is displayed
for several seconds, if a printer is installed it will print
POWER DN. In addition the system automatically attempts
to complete the STERILIZATION stage if the following
parameters are met:
a. If the temperature drop is less than 2.5°C (4.5°F),
sterilization resumes automatically.
b. If the temperature drop is more than 2.5°C (4.5°F), the
cycle fails, POWER DN message is displayed and
printed and LOW TEMP message is displayed.
c. If the pressure drop is more than 4psi (0.27Bar), the
cycle fails, POWER DN message is displayed and
printed and LOW PRES message is displayed.
If a power failure occurred during the HEAT stage, heating
resumes, provided enough water remains in the chamber. If
not, the cycle is aborted, the message “LOW WATER” is
displayed. If a power failure occurs during the dry and
exhaust stages, the unit will automatically resume operation
once the power is back on.
If a power failure occurs during the LIQUIDS PROGRAM,
the system does not allow fast exhaust (as the exhaust valve
is normally closed) during a power failure or when power
resumes.
CYC Finish When the cycle has been completed successfully the
message CYC FINISH is displayed.
