CIP/SIP Cycles
CIP (Cleaning in Place) / SIP (Sterilization in Place)
CIP/SIP cycles are used for cleaning or sterilizing the process-wetted parts
in the process. They are performed for biotech applications, for example.
Depending on the application, one (alkaline solution, water) or more chemicals
(alkaline solution, water, acidic solution, water) are used.
The temperatures for CIP are around 80 °C/176 °F, for SIP around 110 °C/230 °F.
These procedures extremely stress the sensors.
ISM sensors can release a message when a preset number of CIP/SIP cycles is
exceeded. This allows replacing the sensor in time.
Default Values for the Counters
(for Evaluating the Sensor Wear):
CIP = 80
SIP = 700
Autoclaving counter = 750 hours for one cycle

Example of CIP Cycle:
The device automatically recognizes the CIP and SIP cycles and corresponding-
ly increments the counter. The user can specify the max. number of cycles and
decide whether a message is to be generated when this number is exceeded.
These data are not overwritten even after sensor replacement.
The number of CIP cycles is shown in the sensor wear monitor of the
Diagnostics menu when an individual max value has been specified.
Note:
The counters are incremented no earlier than
2 hours after start of the cycle, even if the cycle
itself has already been terminated.
