Function group: SYSTEM PARAMETERS
Diagnostic code
The appropriate error message is shown in this function if the Prowirl 77
measuring system recognizes an error.
The Prowirl 77 measuring system distinguishes between two kinds of errors:
System errors:
In the cyclic data telegram the status is set to “BAD”. In this function an error
code appears. The red LED lights up permanently. These errors directly affect
flow measurement → remedy the error immediately (see below).
Warnings:
In the cyclic data telegram the status is “GOOD” (flow) or “UNCERTAIN”
(totalizer). The red LED flashes. These errors do not affect flow measurement
directly; however these “uncritical” errors must be remedied as soon as
possible.
Note!
When more than one error is present, the one with the highest priority
is diplayed.
