Possible causes / measures
Measuring line broken,
sensor in air or air cushion in assembly,
Potential matching missing in symmetrical
measurement, static charging in media
with lowest conductivity
Temperature sensor defective;
Sensor line interrupted or short-circuited;
Wrong sensor type selected
Measured value outside specified current
range:
Check measured value for plausibility,
if necessary adjust current output assign-
ment 0/4 mA and/or 20 mA.
Dosing devices defective;
Chemical supply empty;
Measured value incorrect -> check for
plausibility and function;
Incorrect control direction set;
incorrect contact assigned;
Incorrect control function assigned
