CIP characteristics: CIP Cycles will be automatically recognized by the sensor. Since CIP cycles
will vary in intensity (duration and temperature) for each application the algorithm of the counter
recognizes an increase of the measurement temperature above a certain level (70 °C for CIP). If
the temperature does not decrease below (60 °C for CIP) within the next 5 minutes after the first
temperature was reached, the counter in question will be incremented by one and also locked
for the next two hours. In the case the CIP would last longer than two hours the counter would
be incremented by one once more.
8.6.3 SIP Cycle Limit
The SIP cycle limit counts the number of SIP cycles if the limit (user defined) is reached, an
alarm can be indicated and set to a certain output relays. The following options are possible:
SIP Max 000
Alarm YES / NO R# choose relay
If the Max setting is on 000, the counter functionality is turned off. The alarm will be reseted after
exchanging the sensor. For oxygen sensors, the counter can be reseted in the ISM Setup menu
(menu Configure).
SIP characteristics: SIP Cycles will be automatically recognized by the sensor. Since SIP cycles
will vary in intensity (duration and temperature) for each application the algorithm of the counter
recognizes an increase of the measurement temperature above a certain level (110 °C for SIP).
If the temperature does not decrease below (100 °C for SIP) within the next 5 minutes after the
first temperature was reached, the counter in question will be incremented by one and also
locked for the next two hours. In the case the SIP would last longer than two hours the counter
would be incremented by one once more.
8.6.4 Autoclaving Cycle Limit
The Autoclaving cycle limit counts the number of Autoclaving cycles if the limit (user defined) is
reached, an alarm can be indicated and set to a certain output relays. The following options are
possible:
Autoclave Max 000
Alarm YES / NO R# choose relay
If the Max setting is on 000, the counter functionality is turned off. The alarm will be reseted after
exchanging the sensor. For oxygen sensors, the counter can be reseted in the ISM Setup menu
(menu Configure).
Autoclave characteristics: Since during the Autoclaving cycle the sensor is not connected to the
transmitter, you will be asked after every Sensor connection, whether the sensor was autoclaved
or not. According to your selection, the counter will be incremented or not.
