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 adjustable limit (parameter 
Temp in °C). If the temperature does not decrease below the defined limit within the next 5 min-
utes after the 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.
8.6.3  SIP Cycle Limit
  Navigate to the menu “SIP Cycle Limit” by using the  and . keys and press [ENTER]. 
  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 OC. The following options are possible:
SIP Max 000    Temp 115 
Alarm  YES / NO  R#  choose OC
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”).
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 adjustable limit (parameter 
Temp in °C). If the temperature does not decrease below the defined limit within the next 5 min-
utes 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
h
  NOTE: The transmitter recognizes the connected ISM sensor and offers this menu only if an auto-
clavable sensor is connected.
  Navigate to the menu “AutoClave Cycle Limit” by using the  and . keys and press [ENTER].
