2 Installation
2.1 General installation instructions
#Warning!
The seal is not allowed to press on the process isolating diaphragm as this could affect the
measurement result.
!Note!
• Due to the orientation of the Deltabar S, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You can correct this zero point
shift either via the "zero" key on the electronic insert, or on the outside of the device or via the
on-site display.
→ See Page 13 , 4.2.1 "Position of operating elements", Page 14 , Section 4.2.2
"Function of the operating elements" or Page
23 , Section 5.1 "Position adjustment".
•For FMD77 and FMD78, please refer to Section 2.3 "Installation instructions for devices with
diaphragm seals", Page 6.
•The FMD77 must only be insulated up to a certain height.
•General recommendations for routing the impulse piping can be found in DIN 19210
"Methods for measurement of fluid flow; differential piping for flow measurement devices" or
the corresponding national or international standards.
•Using a three-valve or five-valve manifold allows for easy commissioning, installation and
maintenance without interrupting the process.
•When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is used,
e.g. by using pipe heat tracing.
•Install the impulse piping with a monotonic gradient of at least 10%.
•Do not clean or touch diaphragm seals with hard or pointed objects.
•To ensure optimal readability of the on-site display, it is possible to rotate the housing up to
380°.

2.3 Installation instructions for devices with diaphragm seals
(FMD78)
!Note!
•The diaphragm seal, together with the pressure transmitter, forms a closed, calibrated system,
which is filled through openings in the diaphragm seal and in the measurement system of the
pressure transmitter. These openings are sealed and must not be opened.
•Do not remove the protection of the process isolating diaphragm protection until shortly before
installation.
•When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in
order to prevent the capillary bending down (bending radius ≥ 100 mm).
•Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero
point shift. The zero point shift can be corrected. → See Page 13, 4.2.1 "Position of operating
elements", Page 14, Section 4.2.2 "Function of the operating elements" or Page 23, Section
5.1 "Position adjustment".
•Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Deltabar S TI00382P, Section "Planning instructions for diaphragm seal
systems" or at "www.endress.com/applicator".
In order to obtain more precise measurement results and to avoid a defect in the device, mount
the capillaries as follows:
•vibration-free (in order to avoid additional pressure fluctuations)
•not in the vicinity of heating or cooling lines
•insulate if the ambient temperature is below ore above the reference temperature
•with a bending radius of ≥100 mm.
•The ambient temperature and length of both capillaries should be the same when using
two-sided diaphragm seal systems.
•Two diaphragm seals which are the same (e.g. with regard to diameter, material, etc.) should
always be used for the negative and positive side (standard delivery).

2.3.1 Vacuum application (FMD78)
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter underneath the lower diaphragm seal. A vacuum load of the diaphragm seal caused
by the presence of filling oil in the capillaries is hereby prevented.
When the pressure transmitter is mounted above the lower diaphragm seal, the maximum
height difference H1 in accordance with the illustration below on the left must not be exceeded.
The maximum height difference is dependent on the density of the filling oil and the smallest
ever pressure that is permitted to occur at the diaphragm seal on the positive side (empty
container), see illustration below, on the right.

4.4 Configuring the device address
Note the following points:
•An address must be assigned to every PROFIBUS PA device. Only when the address is
configured correctly will the device be recognised by the control system/master.
•Each address may only be assigned once in each PROFIBUS PA network.
•Valid device addresses are in the range from 0 to 125.
•The address 126 set at the factory can be used to check the function of the device and to
connect to a PROFIBUS PA network already in operation. This address then has to be changed
in order to integrate additional devices.
•All devices have the address 126 and software addressing on leaving the factory.
•The FieldCare operating program is delivered from the factory with the address 1.
There are two ways of assigning the device address to Deltabar S:
•Using a DP Class 2 master operating program, such as FieldCare or
•On site using the DIP switches
