• Clean Int:
This programme for interval cleaning is permanently assigned to one function. Cleaning times and
repeat cycles are freely adjustable.
You can select and configure Clean Int. only within the "Automatic" control type.
Note that the cleaning times, repeat cycles, etc. that you set here are taken over for all weekdays
and for the Clean programme.
Interval cleaning allows you to define cleaning intervals for a given period of time (max. 1 day).
In practical life, two different operating modes are used, interval measuring and interval cleaning:
– In case of interval cleaning, the sensor is mainly in measuring position. It is cleaned at specified
intervals.
– In case of interval measuring, the sensor is mainly in service position (aggressive media). It is
moved into the process into measuring position at specified intervals. If the sensor remains in
service position for a long time, i.e. you have defined a long integral action time, set the "Air"
to 0 sec to prevent the sensor from drying in.
Examples for programme sequences

ƒig. 46: Example for the programme sequence of "Clean C" and "Clean Int".
• Clean Int runs from 08:00 ... 12:00 at an interval (programme time + measuring time + integral
action time) of 10 minutes.
This means cleaning is started every 10 minutes: 08:00, 08:10, etc.
The last cycle is started at 11:50.
• Clean Int runs from 08:00 ... 11:00 at an interval of 50 minutes.
This means cleaning is started every 50 minutes: 08:00, 08:50, 09:40.
The last cycle is started at 09:40. The cycle due at 10:30 cannot be started because it would be
finished after the set end time at 11:20.
