Safety instructions Cerabar S PMP71 with 4 to 20 mA HART

1 Safety instructions

1.1 Designated use

The Cerabar S is a pressure transmitter for measuring pressure.

The manufacturer accepts no liability for damages resulting from incorrect use or use other than that designated.

1.2 Installation, commissioning and operation

The device is designed to meet state-of-the-art safety requirements and complies with applicable
standards and EC regulations. If used incorrectly or for anything other than the designated use, the
device can, however, be a source of danger e.g. product overflow due to incorrect installation or
configuration. Consequently, installation, connection to the electricity supply, commissioning,
operation and maintenance of the measuring system must be carried out by trained, qualified
specialists authorized to perform such work by the facility's owner-operator. The specialists must
have read and understood these Operating Instructions and must follow the instructions they
contain. Modifications and repairs to the device are permissible only if they are expressly approved
in the manual. Pay particular attention to the information and instructions on the nameplate.

1.3 Operational and process safety

Alternative monitoring measures have to be taken while configuring, testing or servicing the device to ensure operational and process safety.

1.3.1 Hazardous areas (optional)

Devices for use in hazardous areas are fitted with an additional nameplate (→ ä 6). If the measuring system is to be used in hazardous areas, applicable national standards and regulations must be observed. The device is accompanied by separate "Ex documentation" which is an integral part of these Operating Instructions. The installation regulations, connection values and safety instructions listed in this Ex documentation must be observed. The documentation number of the related safety instructions is also indicated on the additional nameplate.

• Ensure that all personnel are suitably qualified.

1.3.2 Functional safety SIL3 (optional)

If using devices for functional-safety applications, strict compliance with the Functional Safety Manual (SD00190P) is mandatory.

2.1.1 Nameplates

!

Note!

• The MWP (maximum working pressure) is specified on the nameplate. This value refers to a reference temperature of 20°C (68°F) or 100°F (38°C) for ANSI flanges.

• The pressure values permitted at higher temperatures can be found in the following standards:
– EN 1092-1: 2001 Tab. 18

1)

– ASME B 16.5a – 1998 Tab. 2-2.2 F316
– ASME B 16.5a – 1998 Tab. 2.3.8 N10276
– JIS B 2220

• The test pressure corresponds to the overpressure limit (OPL) of the device =

2)

MWP x 1.5

.

• The Pressure Equipment Directive (EC Directive 97/23/EC) uses the abbreviation "PS".
The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring
device.

1) With regard to their stability-temperature property, the materials 1.4404 and 1.4435 are grouped together under 13EO

in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.

2) The equation does not apply to PMP71 with a 50 bar (750 psi) or a 100 bar (1,500 psi) measuring cell.

Installation Cerabar S PMP71 with 4 to 20 mA HART

3 Installation

3.1 Incoming acceptance, transport and storage

3.1.1 Incoming acceptance

• Check the packaging and the contents for damage.

• Check the shipment, make sure nothing is missing and that the scope of supply matches your order.

3.1.2 Transporting to the measuring point

Caution!

"

Please comply with the safety instructions and transport conditions for devices weighing over 18 kg
(39.69 lbs).
Transport the device to the measuring point in the original packaging or at the process connection.

3.1.3 Storage

!

The device must be stored in a dry, clean place and protected against damage from impact
(EN 837-2).
Storage temperature range:
See Technical Information TI00383P.

3.2 Installation conditions

3.2.1 Dimensions

For dimensions, please refer to the "Mechanical construction" section in TI00383P.

3.3 Installation instructions

Note!

• Due to the orientation of the Cerabar S, 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 either directly at the device using the "E" key or by remote operation. See

→ ä 23, "Function of the operating elements – onsite display not connected" or
→ ä 35, "Position adjustment".

• To ensure optimal readability of the onsite display, it is possible to rotate the housing up to 380°. → ä 14, "Rotating the housing".

• Endress+Hauser offers a mounting bracket for installing on pipes or walls. → ä 13, "Wall and pipe-mounting (optional)".

3.3.1 Installation instructions

!

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 point (1).
If this is the case, mount the sensor with the pressure compensation point (1) pointing
downwards.

®

• Keep the pressure compensation and GORE-TEX

filter (1) free from contamination and water.

• Cerabar S devices 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.

• To comply with ASME-BPE requirements regarding cleanability (Part SD Cleanability), the device
must be installed as follows:

• All explosion protection data are given in separate documentation which is available upon request. The Ex documentation is supplied as standard with all devices approved for use in explosion hazardous areas.

Taking 4 to 20 mA test signal

A 4 to 20 mA signal may be measured via the positive and test terminal without interrupting the
measurement. The minimum supply voltage of the device can be reduced by simply replugging the
jumper. As a result, operation is also possible with lower voltage sources. To keep the measured
error below 0.1%, the current measuring device should exhibit an internal resistance of < 0.7 Ω.
Observe the position of the jumper in accordance with the following table.

Jumper position for test signal Description

– Taking 4 to 20 mA test signal via plus and test terminal:

possible. (Thus, the output current can be measured without

interruption via the diode.)
– Order configuration
– Minimum supply voltage: 11.5 V DC

– Taking 4 to 20 mA test signal via plus and test terminal:

not possible.
– Minimum supply voltage: 10.5 V DC

4.2.2 Cable specification

• Endress+Hauser recommends using twisted, shielded two-wire cables.

• Terminals for wire cross-sections 0.5 to 2.5 mm

• Cable outer diameter: 5 to 9 mm (0.2 to 0.35 in)

Note!
When operating via a handheld terminal or via a PC with an operating program, a minimum
communication resistance of 250 Ω must be taken into account.

4.2.4 Shielding/potential matching

• You achieve optimum shielding against interference influences if the shielding is connected on
both sides (in the cabinet and at the device). If potential equalization currents are expected in the
plant, only ground the shielding on one side, preferably at the transmitter.

• When using in hazardous areas, you must observe the applicable regulations.
Separate Ex documentation with additional technical data and instructions is included with all
Ex devices as standard.
