Page 30: Cooling Pause
Messages Cooling pause This message indicates that the temperature in chamber 09 is too high to start or continue a cycle (see USE AND MAINTENANCE MANUAL, chapter OPERATION). The steriliser will display this message in STAND BY mode or after starting a cycle and will stop only during the pre-vacuum phase. -
Page 31: Alarms
Alarms ALARMS Alarms indicate the presence of a possible fault and the need for repairs. If a fault occurs during a cycle, the cycle will be immediately interrupted and a buzzer will sound for 15 seconds to indicate the alarm conditions. A description of the alarm will appear on the display along with the cycle and phase when the alarm occurred. -
Page 32: Chamber Level Alarm
Alarms buzzer will sound for 3 seconds when the “Maximum water level” is reached to indicate that the tank is full. If you do not hear the signal, excess water will flow out from the filler. • If the alarm is displayed during the cycle, fill the tank and proceed as shown in the INSUFFICIENT STEAM ALARM procedure. -
Page 33: Insufficient Steam Alarm
Alarms Insufficient steam alarm This alarm indicates leakage of steam from chamber 09. The alarm may appear during a cycle, when the suitable pressure needed to run a cycle is not reached at a temperature of 114°C. Pressure is detected by transducer 38 and temperature by chamber temperature probe 39. -
Page 34: Pressurisation Alarm
Alarms 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. •... -
Page 35: Sterilisation Temperature Band Alarm: Overtemperature / Undertemperature
Alarms Sterilisation temperature band alarm: overtemperature undertemperature Both alarms indicate that the temperature is out of the sterilising band (tolerance) defined by EN 13060. This standard defines the tolerance band (0°C - +4°C) from the setting value during sterilization. For example, if the setting is 134°C, the temperature should be in the band 134°C-138°C. -
