8.6.2 CIP Cycle Limit

Navigate to the menu “CIP Cycle Limit” by using the  and . keys and press [ENTER].

The CIP cycle limit counts the number of CIP 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:

CIP 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 reset after

exchanging the sensor. For oxygen sensors, the counter can be reset (see chapter 8.6.5 “Reset

ISM counter/timer”).

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.

Pressing the [ENTER] key will bring up the Save Changes dialog. Selecting No will

discard the entered values, selecting Yes will make the entered values the current ones.

NOTE: In case of an optical oxygen sensor, the value for CIP Max will also be written to the sen-

sor. The transmitter M400 uploads the value CIP Max from an optical oxygen sensor after the

connection.
