downstream of a shutoff device.

4.3.2

Installation instructions for devices with diaphragm seals –PMP55• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, dependingon the type of diaphragm seal.
• Please note that the hydrostatic pressure of the liquid columns in the capillaries cancause zero point shift. The zero point shift can be corrected.
• Do not clean or touch the membrane of the diaphragm seal with hard or pointed objects.
• Do not remove the protection on the membrane until just before installation.

Installation

NOTICE
Incorrect handling!
Damage to the device!
‣ A diaphragm seal and the pressure transmitter together form a closed, oil-filled calibrated system. The fill fluid hole is sealed and may not be opened.
‣ If a mounting bracket is used, sufficient strain relief must be ensured for the capillaries
in order to prevent them from buckling (bending radius ≥ 100 mm (3.94 in)).
‣ Please observe the application limits of the diaphragm seal fill fluid as detailed in theTechnical Information for Cerabar M TI00436P, "Planning instructions for diaphragm
seal systems" section.
NOTICE
In order to obtain more precise measurement results and to avoid a defect in thedevice, 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 or above the reference temperature!
‣ Mount with a bending radius ≥ 100 mm (3.94 in)!
‣ Do not use the capillaries as a carrying aid for the diaphragm seals!
Vacuum applications
Installation instructions
In vacuum applications, ideally use pressure transmitters with a ceramic measuring membrane (oil-free).
For applications under vacuum, Endress+Hauser recommends mounting the pressuretransmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm
seal caused by the presence of fill fluid in the capillary.
When the pressure transmitter is mounted above the diaphragm seal, the maximum
height difference H1 in accordance with the following illustrations must not be exceeded.
The following illustration shows installation above the lower diaphragm seal:

H1

A0023994

The maximum height difference depends on the density of the fill fluid and the lowest
pressure that is permitted to occur at the diaphragm seal (empty vessel). See illustration
below. The following diagram shows the maximum installation height above the lower
diaphragm seal for vacuum applications.

Mounting with temperature isolator
Endress+Hauser recommends the use of temperature isolators in the event of constantextreme medium temperatures which cause the maximum permissible electronics temperature of +85 °C (+185 °F) to be exceeded. Depending on the fill fluid used, diaphragm seal
systems with temperature isolators can be used for maximum temperatures of up to+400 °C (+752 °F) , see Technical Information, section "Diaphragm seal fill fluids". To minimize the influence of rising heat, Endress+Hauser recommends the device be mounted
horizontally or with the housing pointing downwards. The additional installation heightcauses a zero point shift of maximum 21 mbar (0.315 psi) due to the hydrostatic column
in the temperature isolator. You can correct this zero point shift at the device.

Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
• After welding into the process connection, the measuring cell assembly must be properly
filled with a filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, at the zero point the device display should notexceed 10% of the full scale value of the cell measuring range. The internal pressure of
the diaphragm seal must be corrected accordingly.
• Adjustment / calibration:• The device is operational once it has been fully assembled.
• Perform a reset. The device must then be calibrated to the process measuring range as
described in the Operating Instructions.

Operating concept

The operating concept makes a distinction between the following user roles:

34

User role

Meaning

Operator

Operators are responsible for the devices during normal "operation". This is usually limited to reading process values either directly at the device or in a control room. If the work with the devices
goes beyond reading, it concerns simple, application-specific functions that are used in operation.
Should an error occur, these users simply forward the information on the errors but do not intervene themselves.

Serviceengineer/technician

Service engineers usually work with the devices in the phases following device commissioning. They
are primarily involved in maintenance and troubleshooting activities for which simple settings haveto be made on the device. Technicians work with the devices over the entire life cycle of the product. Thus, commissioning and advanced settings and configurations are some of the tasks they haveto carry out.

ExpertExperts work with the devices over the entire life cycle of the device, but in some cases place highdemands on the devices. Individual parameters/functions from the overall functionality of the devices are required for this purpose time and again. In addition to technical, process-oriented tasks,
experts can also perform administrative tasks (e.g. user administration). "Experts" can access theentire parameter set.

Contains all the parameters that are needed to commission measuring operations. This
submenu has the following structure:• Standard setup parameters
A wide range of parameters, which can be used to configure a typical application, isavailable at the start. The measuring mode selected determines which parameters areavailable.
After making settings for all these parameters, the measuring operation should be completely configured in the majority of cases.
• "Extended setup" submenu
The "Extended setup" submenu contains additional parameters for more accurate configuration of the measurement, for converting the measured value and for scaling the output signal.
This menu is split into additional submenus depending on the measuring mode selected.

Mainte- DiagnonancesisContains all the parameters that are needed to detect and analyze operating errors. This
submenu has the following structure:• Diagnostic list
Contains up to 10 currently active error messages.
• Event logbook
Contains the last 10 error messages (no longer active).
• Instrument info

• Enter reset code

ExpertContains all the parameters of the device (including those already in one of the other submenus). The "Expert" submenu is structured by the function blocks of the device. It thus
contains the following submenus:• SystemContains all the device parameters that do not pertain either to the measurement or to
integration into a control system.
• Measurement
Contains all the parameters for configuring the measurement.
• OutputContains all the parameters for configuring the current output.
• Communication

Operation using Endress+Hauser operating program

The FieldCare operating program is an Endress+Hauser asset management tool based on
FDT technology. With FieldCare, you can configure all Endress+Hauser devices as well as
devices from other manufacturers that support the FDT standard.
Hardware and software requirements can be found on the Internet:
www.de.endress.com → Search: FieldCare → FieldCare → Technical data.
FieldCare supports the following functions:• Configuration of transmitters in online/offline mode
• Documentation of the measuring point• Offline parametrization of transmitters
Connection options:FieldPort SFP20• The configuration data can be uploaded to the DTM with the upload function, modified in the DTM and then downloaded to the download (FDT upload/download).
• More information about FieldCare is available on the Internet(http://www.de.endress.com, Download, → Search for: FieldCare).

Locking/unlocking operation

Once you have entered all the parameters, you can lock your entries against unauthorized
and undesired access.
Locked operation is indicated as follows:• By thesymbol on the local display• The parameters are grayed out in FieldCare and the handheld terminal, which means
they cannot be edited. Information displayed in the "" parameter.
Parameters which refer to how the display appears, e.g. "Language ", can still be altered.
The "Operator code" parameter is used to lock and unlock the device.

Switching signals

The switching signals provide a simple way of monitoring the measured values for limit
violations.
Each switching signal is clearly assigned to a process value and provides a status. This status is transmitted with the process data (process data link). The switching behavior of thisstatus must be configured using the configuration parameters of a "Switching Signal Channel" (SSC). In addition to manual configuration for switch points SP1 and SP2, a teachmechanism is available in the "Teach" menu. This writes the current process value into theselected SSC via a system command. The following section describes the different behaviors of the modes that can be selected. The "Logic" parameter is always "High active". If thelogic is to be inverted, the "Logic" parameter can be set to "Low active".

The calibration is then extended to 0% to 100% and the lower range value (LRV)/upper
range value (URV) are adapted accordingly.

The values for the pressure when the vessel is full or empty are measured automatically during adjustment. As the transmitter automatically sets the pressure values that are best suited
for an "Empty calibration" and a "Full calibration" to the minimum and maximum pressure thattriggers the output current, the correct upper range value (URV) and lower range value (LRV)
must be set.

Calibration without reference pressure (dry calibration)

Example:In this example, a device with a 400 mbar (6 psi) measuring cell is configured for the
0 to +300 mbar (0 to 4.5 psi) measuring range, i.e. the 4 mA value and 20 mA value areassigned 0 mbar and 300 mbar (4.5 psi) respectively.
Prerequisite:
This is a theoretical calibration, i.e. the pressure values for the lower and upper range are
known.
Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. the measured value is not zero in an unpressurized state. For information
on how to perform position adjustment, see →  54.

Information on cleaning

Endress+Hauser provides flushing rings as an accessory to enable the membrane to becleaned without removing the transmitter from the process.
For further information please contact your local Endress+Hauser Sales Center.

9.1.1

Cerabar M PMP55

We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization inplace (steam)) for pipe diaphragm seals. Frequent use of SIP cleaning increases the stressand strain on the membrane. Under unfavorable conditions, frequent changes of temperature can lead to membrane material fatigue and potentially leaks over the long term.

9.2

Exterior cleaning

Please note the following points when cleaning the device:• The cleaning agents used should not corrode the surface and the seals.
• Mechanical damage to the membrane, e.g. due to pointed objects, must be avoided.
• Observe the degree of protection of the device. See the nameplate if necessary →  11.

Pressure specifications

LWARNING
The maximum pressure for the measuring device depends on the lowest-rated element with regard to pressure (components are: process connection, optional mounted
parts or accessories).
‣ Only operate the measuring device within the prescribed limits of the components!
‣ MWP (maximum working pressure): The MWP is specified on the nameplate. Thisvalue refers to a reference temperature of +20 °C (+68 °F) and may be applied to thedevice for an unlimited time. Note temperature dependence of MWP. For flanges, referto the following standards for the permitted pressure values at higher temperatures:
EN 1092-1 (with regard to their stability/temperature property, the materials 1.4435
and 1.4404 are grouped together under EN 1092-1; the chemical composition of thetwo materials can be identical.), ASME B 16.5a, JIS B 2220 (the latest version of thestandard applies in each case). MWP data that deviate from this are provided in therelevant sections of the Technical Information.
‣ The overload limit is the maximum pressure a device may be subjected to during a test.
It is greater than the maximum working pressure by a certain factor. This value refers
to a reference temperature of +20 °C (+68 °F).
‣ The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring
device.
‣ In the case of measuring range and process connection combinations where the overpressure limit (OPL) of the process connection is smaller than the nominal value of themeasuring cell, the device is set at the factory, at the very maximum, to the OPL valueof the process connection. If the entire measuring range must be used, a process connection with a higher OPL value must be selected.
‣ Oxygen applications: The values for "pmax and Tmax for oxygen applications" may not be
exceeded.
‣ Devices with ceramic membrane: avoid steam hammering! Steam hammering cancause zero point drifts. Recommendation: Residue (water droplets or condensation)
may remain on the membrane following CIP cleaning and can result in local steam
hammering the next time steam cleaning takes place. In practice, drying the membrane(e.g. by blowing off excess moisture) has proven to be a successful way of avoiding
steam hammering.
