2.1 General installation instructions
#Warning!
The process seal is not allowed to press on the process isolating diaphragm as this could affect
the measurement result.
!Note!
• If a heated Cerabar S is cooled during the cleaning (e.g. by cold water), a vacuum develops
for a short time, whereby water can penetrate the sensor through the pressure compensation
(1). If this is the case, mount the sensor with the pressure compensation (1) pointing
downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contaminations.
• Do not clean or touch process isolating diaphragm of the diaphragm seals with hard or pointed
objects.

• Due to the orientation of the Cerabar 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. → ä13, Kap. 4.2.1 "Position of operating elements", →ä14,
Kap. 4.2.2 "Function of the operating elements – on-site display not connected" and →ä23,
Kap. 5.3 "Position adjustment".
• For PMP75, please refer to Section 2.3 "Installation instructions for devices with diaphragm
seals", →ä6.
• The PMC71 High temperature version, the PMP72 and the PMP75 must only be insulated
up to a certain height.
• To ensure optimal readability of the on-site display, it is possible to rotate the housing up to
380°.
• The on-site display can be rotated in 90° stages.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
2.2 Installation instructions for devices without diaphragm seals
PMP71, PMP72, PMC71
Cerabar S without diaphragm seal are mounted as per the norms for a manometer
(DIN EN 837-2). We recommend the use of shut-off devices and siphons. The orientation
depends on the measuring application.
2.2.1 Pressure measurement
Pressure measurement in gases
• Mount Cerabar S with shut-off device above the tapping point so that the condensate can flow
into the process.
Pressure measurement in steams
• Mount Cerabar S with siphon below the tapping point. The siphon reduces the temperature
to almost ambient temperature.
• Fill the siphon with fluid before commissioning.
Pressure measurement in liquids
• Mount Cerabar S with shut-off device below or at the same level as the tapping point.
2.2.2 Level measurement
• Mount Cerabar S below the lowest measuring point.
• Do not mount the device at the following positions:
In the fill flow, in the tank outlet or at a point in the container which could be affected by
pressure pulses from an agitator.
• The calibration and functional test can be carried out more easily if you mount the device after
a shut-off device.

2.3 Installation instructions for devices with diaphragm seals
PMP75
!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. The openings are sealed and must not be opened.
• Do not remove the protection of the process isolating diaphragm 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 column in the capillary can cause zero
point shift. 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. → ä13, Kap. 4.2.1 "Position
of operating elements", →ä14, Kap. 4.2.2 "Function of the operating elements – on-site
display not connected" and →ä23, Kap. 5.3 "Position adjustment".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for TI383P (PMP75); TI438P (PMP72), 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.

2.3.1 Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter underneath the diaphragm seal. A vacuum load of the diaphragm seal caused by the
presence of filling oil in the capillary is hereby prevented.
When the pressure transmitter is mounted above the 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 (empty container), see illustration
below, on the right.

• If operation is locked by means of the DIP-switch, you can only unlock operation again by
means of the DIP-switch. If operation is locked by means of remote operation e.g. FieldCare,
you can only unlock operation again by means of remote operation.

#Warning!
• If a pressure that is lower than the minimum permitted pressure is present at the device,
messages "E120 sensor low pressure" and "E727 sensor pressure error - overrange" are output
in succession.
• If a pressure that is greater than the maximum permitted pressure is present at the device,
messages "E115 sensor overpressure" and "E727 sensor pressure error - overrange" are output
in succession.
• The messages E727, E115 and E120 are "Error"-type messages and can be configured as a
"Warning" or an "Alarm". The factory setting for these messages is "Warning". This setting
prevents the BAD status from being transmitted in applications (e.g. cascade measurement)
where the user is aware of the risk of the sensor range being overshot.
• We recommend setting messages E727, E115 and E120 to "Alarm" in the following instances:
– It is not necessary to violate the sensor range for the measuring application.
– A position adjustment must be carried out that has to correct a large measured error as a
result of the orientation of the device.
5.1 Commissioning via an FF configuration program
!Note!
• The device is configured for the Pressure measuring mode as standard. The measuring range
and the unit in which the measured value is transmitted, as well as the digital output value of
the Analog Input Block OUT, correspond to the data on the nameplate. Following a reset with
code 7864, the OUT parameter may have to be rescaled (see also →ä32, Section 5.6
"Scaling the OUT parameter").
1. Switch on the device.
2. Open the configuration program.
3. Load Cff and device description files into the host system or the configuration program.
Make sure you are using the right system files.
4. Identify the device using the DEVICE_ID. Assign the desired tag name to the device by
means of the PD_TAG parameter.
