NOTICE

4.5 Installing Cerabar M

• Due to the orientation of the Cerabar M, there may be a shift in the zero point, i.e. when the container is empty or partially full, the measured value does not display zero. You can correct this zero point shift  ä 47, Section "Function of the operating elements" or  ä 64, Section 8.4 "Position zero adjustment".

• For PMP55, please refer to Section 4.5.2 "Installation instructions for devices with diaphragm seals – PMP55",  ä 17.

• Endress+Hauser offers a mounting bracket for installing on pipes or walls.  ä 21, Section 4.5.5 "Wall and pipe mounting (optional)".

4.5.1 Installation instructions for devices without diaphragm seals –

PMP51, PMC51

Damage to the device!

If a heated Cerabar M is cooled during the cleaning process (e.g. by cold water), a vacuum develops for a short time, whereby moisture can penetrate the sensor through the pressure compensation (1).

‣ If this is the case, mount the Cerabar M with the pressure compensation (1) pointing

downwards.

• Keep the pressure compensation and GORE-TEX

• Cerabar M transmitters without diaphragm seals are mounted as per the norms for a manometer (DIN EN 837-2). We recommend the use of shutoff devices and siphons. The orientation depends on the measuring application.

• Do not clean or touch process isolating diaphragms with hard or pointed objects.

• The device must be installed as follows in order to comply with the cleanability requirements of the ASME-BPE (Part SD Cleanability):

filter (1) free from contamination.

Cerabar M, Deltabar M, Deltapilot M Installation

NOTICE

4.5.2 Installation instructions for devices with diaphragm seals – PMP55

• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, depending on

the type of diaphragm seal.

• 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.

• Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or

pointed objects.

• Do not remove process isolating diaphragm protection until shortly before installation.

Improper 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.

‣ 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 (3.94 in)).

‣ Please observe the application limits of the diaphragm seal filling oil as detailed in the

Technical Information for Cerabar M TI00436P, "Planning instructions for diaphragm seal systems" section.

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 or above the reference temperature ‣ With a bending radius of  100 mm (3.94 in). ‣ Do not use the capillaries as a carrying aid for the diaphragm seals!

Vacuum application

For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter 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 illustrations below must not be exceeded.

A0023994

Fig. 9: Installation above the lower diaphragm seal

The maximum height difference depends on the density of the filling oil and the smallest ever pressure that is permitted to occur at the diaphragm seal (empty vessel), see illustration below:

Mounting with temperature isolator

Endress+Hauser recommends the use of temperature isolators in the event of constant extreme medium temperatures which lead to the maximum permissible electronics temperature of +85 °C (+185°F) being exceeded. Depending on the filling oil used, diaphragm seal systems with temperature isolators can be used for maximum temperatures of up to 400 °C (+752 °F). For the temperature application limits, see technical Information, "Diaphragm seal filling oils" section. To minimize the influence of rising heat, Endress+Hauser recommends the device be mounted horizontally or with the housing pointing downwards. The additional installation height also brings about a maximum zero point shift of 21 mbar (0.315 psi) due to the hydrostatic column in the temperature isolator. You can correct this zero point shift at the device. The temperature restrictions are lowest with an insulation height of 30 mm (1.18 inch). Full insulation exhibits virtually the same behavior as no insulation! The temperature limits with an insulation height of 30 mm (1.18 inch) are illustrated in the following graphic.

6.3 Operation with an operating menu

6.3.1 Operation concept

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

User role Meaning

Operator Operators are responsible for the devices during normal "operation". This is usually limited

Service engineer/ technician

Expert Experts work with the devices over the entire product life cycle, but their device

to reading process values either directly at the device or in a control room. If the work with the devices extends beyond value read-off tasks, the tasks involve simple, applicationspecific functions that are used in operation. Should an error occur, these users simple forward the information on the errors but do not intervene themselves.

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 have to be made at 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 have to carry out.

requirements are often extremely high. 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 avail of the entire parameter set.

6.3.2 Structure of the operating menu

User role Submenu Meaning/use

Operator Language Only consists of the "Language" parameter (000) where the operating

language for the device is specified. The language can always be changed even if the device is locked.

Operator Display/operat. Contains parameters that are needed to configure the measured value

display (selecting the values displayed, display format, display contrast, etc.). With this submenu, users can change the measured value display without affecting the actual measurement.

Service engineer/ technician

Setup 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, is available at the start. The measuring mode selected determines which parameters are available. After making settings for all these parameters, the measuring operation should be completely configured in the majority of cases.

• "Extended setup" submenu The "Setup" submenu contains additional parameters for more indepth configuration of the measurement operation to convert the measured value and to scale the output signal. This menu is split into additional submenus depending on the measuring mode selected.

6.3.3 Operation with a device display (optional)

A 4-line liquid crystal display (LCD) is used for display and operation. The local display shows measured values, dialog texts, fault messages and notice messages. For easy operation the display can be taken out of the housing (see figure steps 1 to 3). It is connected to the device through a 90 mm (3.54 in) cable. The display of the device can be turned in 90° stages (see figure steps 4 to 6). Depending on the orientation of the device, this makes it easy to operate the device and read the measured values.

If this value is not equal to "0", it can be corrected to "0" by the position adjustment.

Position zero adjustment – the pressure difference between zero (set point) and the measured pressure need not be known.

Example:

– Measured value = 2.2 mbar (0.033 psi) – You correct the measured value via the "Pos. zero adjust" parameter with the

"Confirm" option. This means that you assign the value 0.0 to the pressure

present. – Measured value (after pos. zero adjust) = 0.0 mbar – The current value is also corrected.

Position adjustment – the pressure difference between set point and the measured pressure must be known.

Example:

– Measured value = 982.2 mbar (14.73 psi) – You correct the measured value with the value entered (e.g. 2.2 mbar (0.033

psi)) via the "Calib. offset" parameter. This means that you are assigning the

value 980.0 (14.7 psi) to the pressure present. – Measured value (after calib. offset) = 980.0 mbar (14.7 psi) – The current value is also corrected.

Example:

In this example a wet calibration is shown when it is not possible to empty the vessel and then fill it up to 100%. Here a 20% filling is used as “Empty” and a “25%” filling is used as “Full” calibration point. The calibration is then extended to 0% ... 100% and LRV / URV are adjusted accordingly.

Prerequisite:

The default value in the level mode for calibration mode is “Wet”. However, it can be changed via: Setup  Extended Setup  Level  Calibration mode

Settings can result in non-permitted use of the "Electr. Delta P" function.

The measured value of the transmitting device (via burst) must always be greater than the measured value of the receiving device (via the "Electr. Delta P" function). Adjustments that result in an offset of the pressure values (e.g. position adjustment, trim) must always be performed in accordance with the individual sensor and its orientation, irrespective of the "Electr. Delta P" application. Other settings result in non-permitted use of the "Electr. Delta P" function and can lead to incorrect measured values.

8.10 Flow measurement (Deltabar M)

8.10.1 Information on flow measurement

In the "Flow" measuring mode, the device determines a volume or mass flow value from the differential pressure measured. The differential pressure is generated by means of primary elements such as pitot tubes or orifice plates and depends on the volume or mass flow. Four flow types are available: volume flow, norm volume flow (European norm conditions), standard volume flow (American standard conditions), mass flow and flow in %.

In addition, the Deltabar M software is equipped with two totalizers as standard. The totalizers add up the volume or the mass flow. The counting function and the unit can be set separately for both totalizers. The first totalizer (totalizer 1) can be reset to zero at any time while the second (totalizer 2) totalises the flow from commissioning onwards and cannot be reset.

The totalizers are not available for the "Flow in %" flow type.

8.11.6 Level selection "in height" Calibration without reference pressure (dry calibration)

Example:

In this example, the volume in a tank should be measured in liters. The maximum volume of 1000 liters (264 US gal) corresponds to a level of 4 m (13 ft). The minimum volume of 0 liters corresponds to a level of 0 m. The density of the medium is 1 g/cm

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• This is a theoretical calibration i.e. the pressure and volume values for the lower and upper

calibration point must be known.

The values entered for "Empty calib./Full calib." and " Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a message output, if the values are too close together. Other limit values are not checked, i.e. the values entered must be appropriate for the sensor and the measuring task for the device to be able to measure correctly.

9.1 Cleaning instructions

Endress+Hauser offer flushing rings as accessories to clean process isolating diaphragms without taking the transmitters out of 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 in place (steam)) for pipe diaphragm seals. A frequent use of sterilization in place (SIP) will increase the stress on the process isolating diaphragm. Under unfavorable circumstances in the long term view we cannot exclude that a frequent temperature change could lead to a material fatigue of the process isolating diaphragm and possibly to a leakage.

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 process isolating diaphragm, e.g. due to pointed objects, must

be avoided.

• Observe the degree of protection of the device. See the nameplate if necessary ( ä 8 ff).
