ABB ProcessMaster FEP630 series User Manual

FEP630, FEH630 ELECTROMAGNETIC FLOWMETER | OI/FEP630/FEH630-EN REV. D 121
Monitoring the grounding
The function checks for noise in the measuring signal and the
electrical grounding of the device. While the check is in progress,
no flow measurement can take place.
The noise / grounding check is started manually and delivers a
‘successful / failed’ result.
The measurements (Power Spectrum, Amplitude 1 to 4 and
Frequency 1 to 4) will help if the noise / grounding check fails.
Requirements for use:
• The sensor must be filled completely with measuring
medium.
• There is no flow through the sensor (close all valves, shut-
off devices etc.)
• The sensor must be grounded (see Sensor grounding on
page 29).
• There may not be any deposits on the measuring
electrodes.

Verification
Fingerprint database
The sensor and transmitter fingerprint stored in the
SensorMemory allows you to compare the state of the device at
the time of manufacture at the factory with the current state of
the device at the customer site.
The check is started manually and returns a ‘successful / failed’
result.
If the verification is unsuccessful, troubleshooting information is
shown on the display (parameter ‘Rslt FP Verification‘).
A software tool (ABB Ability SRV500) is available for
documentation and trend analysis.
