7.4.6 Check
The CHECK function group is only available for devices with a Plus Package.
In the CHECK function group, you can select different monitoring functions for the
measurement.
Polarization detection (field P1)
In the case of conductive sensors, the effects of polarization in the boundary layer between
the sensor and medium restrict the measuring range. The transmitter can detect
polarization effects by using a smart signal analysis process. Error message E071 is
displayed.
Alarm threshold monitoring (fields P2 to P5)
You can use this function to monitor the measured value for permissible upper and lower
limits and trigger an alarm (error messages E154, E155).
PCS alarm (process check system), (fields P6 to P9)
AC (alternation check; sensor activity monitoring): The function AC (field P6) is used to
check measuring signals for deviations. An alarm (E152) is triggered if the measuring
signal remains constant within the space of one hour. The reason for such sensor behavior
can be contamination, cable open circuit or similar.
CC (controller check): You can monitor the controller activity with the CC function . This
function is primarily suited to batch operation and single-sided limit switches. A
malfunction of the controller is detected and reported thanks to freely adjustable
monitoring times (E156, E157).
