Corrective measures
72 Detected sensor drift exceeds alarm
level [drA]
Drift exceeds alarm threshold�
Temperature measurement with reduced
accuracy possible�
►
Replace the unit�
►
Check whether the parameter [drA] is
programmed correctly�
91 Supply voltage outside the operating
voltage range�
► Check the supply voltage; ensure a
correct voltage supply�
92 Operating temperature of the electronics
outside the specified range�
►
Check the temperature of the upper
part of the unit�
►
Adhere to the specified temperature
range�
100 Error during parameter setting via IO-
Link (set value of a parameter outside
the valid range)�
►
Repeat parameter setting with
admissible parameter values or make
a reset (reset all parameters to the
factory setting)�
*[drEd] = [On] or [Ondr]�
