1.1 Software history
The "Electronic Revision" (ER) is consulted to document the revision status of electronic equipment according to NE 53 for all GDC devices. It is easy to see from the ER whether troubleshooting or larger changes in the electronic equipment have taken place and how that has affected the compatibility.
Changes and effect on compatibility
1 Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
mistakes on display)
2-_ Downwards compatible hardware and/or software change of interfaces:
H
HART
P PROFIBUS
F Foundation Fieldbus
M Modbus
X all interfaces
3-_ Downwards compatible hardware and/or software change of inputs and outputs:
I Current output
F, P Frequency / pulse output
S Status output
C Control input
CI Current input
X all inputs and outputs
4 Downwards compatible changes with new functions
5 Incompatible changes, i.e. electronic equipment must be changed.

4.7 Grounding the measuring sensor
4.7.1 Classical method
CAUTION!
There should be no difference in potential between the measuring sensor and the housing or protective earth of the signal converter!
• The measuring sensor must be properly grounded.
• The grounding cable should not transmit any interference voltages.
• Do not use the grounding cable to connect more than one device to ground at the same time.
• In hazardous areas, grounding is used at the same time for equipotential bonding. Additional
grounding instructions are provided in the separate Ex documentation, which are only supplied together with hazardous-duty equipment.
• The measuring sensors are connected to ground by means of a functional grounding conductor FE.
• Special grounding instructions for the various measuring sensors are provided in the separate documentation for the measuring sensor.
• The documentation for the measuring sensor also contain descriptions on how to use grounding rings and how to install the measuring sensor in metal or plastic pipes or in pipes which are coated on the inside.

4.7.2 Virtual reference (not valid for TIDALFLUX 4000 & OPTIFLUX 7300 C)
For pipelines which are electrically insulated on the inside (e.g. have an inner liner or are made completely out of plastic), it is also possible to measure without additional grounding rings or electrodes. The signal converter's input amplifier records the potentials of both measuring electrodes and a patented method is used to create a voltage which corresponds to the potential of the ungrounded medium. This voltage is then the reference potential for signal processing. That means there are no interfering potential differences between the reference potential and the measuring electrodes during signal processing. Ungrounded use is also possible for systems with voltages and currents in the pipelines, e. g. electrolysis and galvanic systems.
INFORMATION!
If there is a virtual reference with wall housing, voltage is permitted between PE/FE of the converter and the measuring sensor!
