Caution
means that failure to take the prescribed precautions could result
light severe bodily injury or material damage!
Note

information about the product, handling the product or about a
section of the documentation that is of particular importance.
Proper use of the device
Caution
The operator is responsible for ensuring that
the material used in the sensor and housing is
suitable and that such material meets the
requirements for the fluid being used and the
ambient site conditions. The manufacturer
accepts no responsibility in regard to such
material and housing.
Caution
In order for the device to perform correctly
and safely, it must be shipped, stored, set up,
mounted operated and maintained properly.
Return for servicing or calibration
Before returning your flowmeter for servicing or calibration,
make sure it is completely clean. Any residues of substances that
could be hazardous to the environment or human health are to
be removed from all crevices, recesses, gaskets, and cavities of
the housing before the device is shipped!
Caution
The operator is liable for any loss or damage
of any kind, including personal injury, decon-
tamination measures, removal operations and
the like that are attributable to inadequate
cleaning of the device.
Any device returned for servicing is to be
accompanied by a certificate as specified
in „Product return form”!
The device is to be accompanied by a document describing the
problem. Please also quote the name of a contact person. This
will help to repair your device as expeditiously as possible and
therefore minimize the cost of repairing it.
Replacement of the transmitter electronics
Before replacing the transmitter electronics, read the safety
instructions in Section „
Replacement of transmitter electronic”
on page 12.
Caution
Make sure that you obey the applicable stan-
dards and regulations pertaining to electrical
devices, device installation and process tech-
nology when replacing the transmitter elec-
tronics. The highly integrated electronic com-
ponents of the device are ESD sensitive.
Caution
The complete unit has to be replaced with all
of its printed boards (except for the memory
chip (DSM)). The specified precision and
interchangeability of the electronics are only
guaranteed if the complete insert is replaced.

Commissioning
Installation of magnetic-inductive flowmeters
At the installation of the magnetic-inductive flow sensor the
instructions and notes of the assembly instructions and operating
manuals have to be followed. Also, abserve the regulations of
grounding, potential equalization and company-internal groun-
ding guidelines.
Potentials
All outputs are electrically isolated from the auxiliary power, the
sensor circuit and from each other. The housing and the inter-
ference suppression filters of the power supply are connected to
PE.
The electrodes and measuring electronics are related to the
potential of the function earth FE of the sensor. FE is not
connected to PE, but may be connected with each other in the
sensor junction box. If the sensor is grounded by using ground
disks (earthing rings), these must in connected with the function
earth FE.
At a separate assembly of sensor and transmitter the outer
screen of the connecting cable is connected to the transmitter
housing and has PE potential. The inner screens of the electrode
line are connected to FE inside the junction box of the sensor and
to the mass (GND) of the transmitters electronic.
Details of all wirings, terminals and drawing can be found in the
chaper „Wiring diagrams” starting at page 9.
Cathodic protective units
Using a cathodic protective unit to avoid corosion, which put a
voltage to the tube wall, it must be connected to terminal FE.
The transmitter boards, control panal and internal switches are
on the same potential as FE.
