Proline Promag 50 PROFIBUS DP/PA
Cause/remedy
Cause:
Alarm from empty pipe detection (EPD).
The measuring tube is only partially filled or empty.
Remedy:
1. Check the process conditions of the plant.
2. Fill the measuring tube.
Cause:
EPD adjustment not possible because the fluid's
conductivity is either too low or too high.
Remedy:
The EPD function cannot be used with fluids of this
nature.
Cause:
The EPD adjustment values for an empty pipe and full
pipe are identical, therefore incorrect.
Remedy:
Repeat EPD adjustment, observing procedure closely
