General
!
Note!
The output signals (e.g. pulse, frequency) of the measuring device must correspond to the
higher-order controller.

No. Error message / Type Cause/remedy
351 to 354
System error message (S)/
Notice message (!)

Current output
The current flow is outside the set range.
1. Change the upper range or lower range values entered
2. Increase or reduce flow, as applicable

Process error message (P)/
Notice message (!)
EXC. CURR. LIM
# 701
The maximum current value for the measuring tube exciter coils
has been reached since certain fluid characteristics, e.g. high gas or
solid content, are in the limit range. The device continues to work
correctly.
In particular with outgassing fluids and/or increased gas content,
the following measures are recommended to increase system
pressure:
1. Install the measuring device downstream of a pump
2. Mount the device at the lowest point in an ascending pipeline
3. Install a valve or an orifice plate downstream from the
measuring device
