Certificate of compliance with his specification, issued and signed by the

manufacturers quality control authority

Test Certificate

Manuals of operation and maintenance

2. IDES ACCEPTANCE CONTROL

2.1 GENERAL

Process control equipment should be supplied properly packed and with enclosed

specific technical literature, as installation and operation manuals and certificates

as required in the IDE equipment specification.

Special attention should be given to equipment received with damaged packing,

looking for structural damages and missing parts.

2.2 INSPECTION OF DOCUMENTATION

Inspect the bill of lading and compare it with IDEs order. If any discrepancies are

found, inform the purchasing and projects dept.

Check if all technical documentation as specified in the equipment specification

was supplied with the equipment.

3. EQUIPMENT INSPECTION

3.1 Inspect the instruments and the components for cracks or other structural damages.

3.2 Visually check where applicable that the indicator scale is as specified.

3.3 Check that the cut-out dimensions are as specified.

3.4 Compare the equipment labels and ensure that they are similar to the data specified

in the EP.

3.5 Using the suppliers catalog, identify the controller parts as specified and check for

material and type compliance with IDEs spec. Special attention is required for

checking the end connections, type and standard of flanges or threads.

!Caution

1. Safety instructions

The appropriate national safety regulations (i.e. EN 837-2 Selectionand installation recommendations for pressure gauges) must beobserved when installing, putting into operation and running theseinstruments.

T Serious injuries and/or damage can occur should the appropriateregulations not be observed

T Only appropriately qualified persons should work on theseinstruments

T The actual maximum surface temperature is not generated bythe instruments themselves, but primarily by the respectivemedium temperature! For permissible maximum mediumtemperatures see table 1.

1. Safety instructions / 2. Description

2. Description

T Nominal size 100 and 160 mm

T The pressure gauges measure the pressure by means of resilient bourdontube measuring elements

T The measuring features are in accordance with the standards EN 837-1

T In addition the case and bezel ring as well as the pressurised components ofmodels 23X.30 and 23X.36 also meet the requirements of this standard onsafety pattern pressure gauges with solid baffle wall (code S3).

Working pressure

Model 23X.50/30: Steady: full scale valueFluctuating: 0.9 x full scale valueShort time: 1.3 x full scale value

Model 23X.36: Steady: full scale valueFluctuating: 0.9 x full scale value

Short time: overload range

Pressure connection

T According to the general technical regulations for pressure gauges,respectively (i.e. EN 837-2 "Selection and installation recommendations forpressure gauges").

When screw-fitting the gauges the force required for sealing must not beapplied through the case or terminal box but, using a suitable tool, only throughthe spanner flats provided for this purpose at the square of the connector.

Installation withopen-end wrench

Temperature effect

When temperature of the pressure element deviates from reference temperature(+20 C): max. 0.4 %/10 K of true scale value

Operating Temperature

Ambient (in Ex-operation): Model 232 -40 ... +60 CModel 233 -20 ... +60 C

Medium: The permissible medium temperature does not only depend on theinstrument design, but also on the ignition temperature of thesurrounding gases, vapours or dust. Both aspects have to betaken into account. For permissible maximum mediumtemperatures see table 1.

Attention! With gaseous substances the temperature may increase as a resultof the compression temperature. In such cases the pressure change rate has tobe slowed down resp. the permissible medium temperature has to be reduced.

Permissible vibratory stress at the mounting location

T As a matter of principle the instruments should only be mounted at locationswithout vibratory stresses

T Where required, a decoupling from the mounting location can be achievede.g. by a flexible connecting line from the measuring point to the pressure

gauge and mounting via a measuring instrument bracket.

T If this is not possible, the following limits must not be exceeded:

Dry gauges: Frequency range < 150 Hz(Model 232) Acceleration < 0.7 g (7 m/s2)

Liquid-filled gauges: Frequency range < 150 Hz(Model 233) Acceleration < 4 g (40 m/s2)

The liquid filling has to be checked on a regular basis.The liquid level must not drop below 75% of the gauge diameter.


Installation

T Nominal position per EN 837-1 / 9.6.7 Figure 9: 90 ( )

T Pressure connection: lower mount (LM) or lower back mount (LBM)

T In order to ensure that with both models 23X pressure can be safely andreliably vented through the case back, a distance of at least 25 mm has toremain free behind the case!

T In order to avoid any additional heating, the instruments must not beexposed to direct solar irradiation while in operation!

T With filled versions the ventilating valve at the top of the case must beopened prior to commissioning!

4. Commissioning ... 6. Repairs

4. Commissioning

During the commissioning process pressure peaks must be absolutely avoided.Open the shut-off valves slowly.

5. Maintenance and servicing / cleaning

The instruments require no maintenance or servicing.

The indicator and switching function should be checked once or twice every12 months. The instrument must be disconnected from the process to checkwith a pressure testing device.

The instruments should be cleaned with a damp cloth moistened with soapsolution.

6. Repairs

Repairs are to be only carried out by the manufacturer or appropriately trainedpersonnel.
