3. DOMINA PLUS B remains in this condition until the surface temperature reaches 100°C (up and down)

4. When the vacuum pump turns on, it runs without load because EV5 is open

5. After a couple of seconds, EV5 turns on (it closes)

6. After a couple of seconds, EV3 turns on (it open) and the air is pumped out

7. When the pressure reaches –0.8 bar, (for altitude from 0 to 100 m), EV3 closes and EV4 opens

8. EV5 open and the drain pump turns on for 20 seconds

10. heating

11. When the pressure reaches 0.16 bar, EV2 turns off

12. At 0.05 bar, EV2 closes and the vacuum pump turns on

13. ..after 2 seconds EV5 closes..

14. ..and after 2 seconds EV3 opens: the steam is condensed in the radiator and the pump works dry

38. In the gray handle model, the valves 3 are wired together, in the 2001 model the N.O. becomes EV5

39. THIS PHASE IS MINIMUM 10 SEC. LONG OR UNTIL THE SURFACE TEMPERATURE REACHES 100°C BUT THE VALVES ARE OFF, THE AIR EXPANDES

40. EV 3/2 is open, so, when the pump turns on, it is free of load. Look at the arrows for the flow.

41. After 2 seconds the valves NR 3 turn on. Now the chamber is connected to the pump. The pressure must be -0.8 bar before to skip to the next phase

42. The water goes in the chamber trough the filter and the water counter.

43. After 10 seconds, the pump turns off, when the quantity of measured water will be 180 cc EV 4 closes.

44. The chamber is sealed and heated until the pressure reaches 0.18 bar.

45. Until the pressure reaches 0.05 bar.

46. Then, EV 2 closes and the pump turns on and after 2 seconds….

47. Both EV 3 turn on, air and steam come from the chamber trough the condensers. In this part, the water fall down for the gravity and the air goes to the pump until the pressure reaches -0.8 bar

48. Now the water is filled again in the chamber, EV 3 turn off, and the water present here is pumped to the waste water tank.

49. The pump turns off after 10 seconds, EV 4 turns off when the filled water is 128 cc

50. Now the sequence is the same.

55. The last filling is 250 cc of water

56. In the last heating phase, at 0.3 bar, the temp/press ratio is controlled, if it is wrong, the cycle is aborted with an AL8 alarm.

71. ALARMS There are three levels of signals. Some messages are displayed using alphanumeric codes. For example this message means that the recovery water reservoir is full. The second level of indications warn that something doesn’t work perfectly but the sterility of the load is warranted. The operator manual report a list of procedure that may solve the problem directly by the final user. These messages disappears opening the door. The message FAIL followed by an indication AL with a number means that the cycle is interrupted and failed, the load was not sterilised. All the active components are turned off. Opening the door, the message is not cancelled.

72. MESSAGGES NEED CLEANING NEED SERVICE ADD H2O FULL H20 H2O GOOD H2O HARD OPEN DOOR DRY FAIL NEED INST ALARMS AL AL1 AL2 AL3 AL4 AL5 AL6 AL7 AL8 AL9 AL10 AL11 AL12 AL13 AL14 AL15 AL16 AL18 AL31 ALARMS CD CD1CD1 CD2 CD3CD4CD2 CD3CD4 CD5CD5 CD6 CD7CD6CD7

73. NEED CLEANING After the first 60 cycles, if the maintenance cycle is not done, this message appears. The autoclave works properly, but the message will disappear only when the maintenance will be done correctly and it will be displayed again after 60 cycles. Read the paragraph MAINTENANCE of the user manual.

74. H2O FULL ADD H2O These messages means the was pushed the START button with the indication MIN of the clean water or MAX of the used water. It is necessary to empty the used water reservoir and to fill the clean water reservoir before to run a cycle.

75. H2O GOOD H2O HARD These messages indicate the quality of the water in the clean reservoir. Turning on the autoclave, if the chamber is cold and the clean water reservoir is full, a measure of the conductivity is done. The switch level from good to bad is 15 microSiemens. The autoclave permits to run cycles also if the water conductivity is too high, it is an operator’s decision to run cycles with water that can damage the instruments.

76. OPEN DOOR It means that the START button was pushed with the door not properly closed.

77. DRY FAIL The door was opened during the drying phase in a cycle where the drying is not considered fundamental (3 and special 4)

78. NEED INST This message appears trying to turn on the autoclave without following the correct procedure of installation. The sequence must be: maintaining pushed the button 1, push POWER. The door must be close and the clean water reservoir must be filled over the minimum level. It is possible to force again the message NEED INST pushing together 4 and POWER from off condition. This function was designed for the following transfers of the autoclave for service or maintenance in a service centre.

79. NEED SERVICE After one year from the installation date (or before is 2000 cycles are done), this message indicate that it is time for a special maintenance and for a check of the calibration. It is enough push a button to cancel this message and use the autoclave, but it will appears again at the next turning on. To cancel completely this message (for one year) it is necessary to press together the first three program buttons from the off condition. This function was inserted for the future application of the European norm EN554.

80. AL 6 The vacuum level is not enough. The switch level depend on the altitude setting and on the phase. Altitude Mt first vacuum bar following vacuum bar 0-100-0,76-0,7 200-300-0,74-0,68 400-500-0,72-0,66 600-700-0,7-0,64 800-900-0,68-0,62 1000-1100-0,66-0,6 1200-1300-0,64-0,58 1400-1500-0,62-0,56 1600-1700-0,6-0,54 1800-1900-0,58-0,52 2000-2100-0,56-0,5 2200-2300-0,54-0,48 2400-2500-0,52-0,46 the causes and the solutions are described in the CD7 paragraph.

81. AL 8 After three vacuum phases there is too much air in the chamber. This control is done when the pressure reaches 0,3 bar: the temperature must be higher than 104°C. The most frequent cause is a too low altitude setting. An excessive amount of air may be caused by a chamber or a valve during a vacuum phase. Run the vacuum test. A wrong adjustment of temperature or pressure sensor may force this alarm or a wrong function of the air exhaust system.

82. AL 16 The pressure reading was higher than 2,4bar. May be that the heater are out of, check the paragraph AL10. Verify if the pressure board is correctly inserted on the main board; eventually replace it with a new calibrated board. Don’t try to adjust it if you don’t have a high grade pressure reference.
