Pressurisation alarm
This alarm indicates that the temperature has not increased properly in
chamber
09
during
the steam phase (steam or pressurisation peaks).
The steriliser may display this alarm during a cycle, during steam phases, when the pressure
does not correspond to the saturated steam curve.
•
Follow the instructions in the INSUFFICIENT STEAM ALARM solution.
•
If the alarm persists, there could be a fault in the heating circuit. Check that during
pressurisation or steam peaks (fractioned vacuum), the chamber internal coil is
correctly powered (see wiring diagrams).
•
Replace
chamber probe
21
(see technical newsletter).
Overtemperature alarm
The alarm indicates that temperature inside
chamber
09
has exceeded 150°C.
The steriliser may display this alarm when the temperature reaches 150°C.
•
Check that the wires of the
chamber temperature probe
39
and the
transducer
38
are
neither disconnected, nor worn or faulty.
•
Check the correct load positioning, which should be correctly arranged on the
supports.
•
Replace
chamber probe
21
(see technical newsletter).
Insufficient vacuum alarm
This alarm indicates that during the pre-vacuum phase, the pressure did not drop to the
correct set value.
This alarm is displayed during the pre-vacuum phase of a cycle when the pressure does not
drop to the correct value in the expected time.
•
Check the efficiency and cleanliness of
chamber seal
31
and of the flange of
chamber
09
on which it is fitted. Replace if damaged.
•
Check
vacuum pump
41
(see ADDITIONAL CHECKS AND SETTINGS – Vacuum Pump).
•
Check correct positioning of
drain filter
20
and its cleanliness.
•
Check correct positioning of
fans
42
.
•
Check that the steriliser is sufficiently ventilated.
Fractioned vacuum alarm
This alarm indicates that vacuum was not created inside
chamber
09
.
This alarm is displayed during a cycle, during a vacuum pulse in the fractioned vacuum
phase, when the pressure does not drop to the correct value in the expected time.
•
Check that the total maximum load weight was not exceeded and that the materials
forming the load are compatible with the selected cycle (see USE AND MAINTENANCE
MANUAL, chapter OPERATING USE), for example, NEVER mix fabrics with solid materials.
•
Check correct positioning of
fans
42
.
•
Check the steriliser is sufficiently ventilated (in particular if built-in).
•
Check that
vacuum pump
41
is properly powered and that it works correctly.
