1 Instrument Safety Standards

1 Instrument Safety Standards

1.1 Safety standard of equipment

• The equipment corresponds to state-of-the-art technology and present safety rulings. It has been inspected and its technical safety condition was perfect when it left the factory.

• Please note the special information provided for commissioning the explosion-proof equipment ver-sion. You will find this in the Ex chapter of the main operating manual (Technical data of explosion-proof version)

• The measurement equipment satisfies the EMC requirements defined in EN61326 / NAMUR NE21.

For pressure equipment consisting of assemblies, we can only certify CE conformity for equipment in itsdelivery condition. Only the factory, service staff or an authorized specialist workshop may replace com-ponents. CE conformity will be voided if the operators themselves replace components

1.2 Instructions for the use of pressure equipment functioning on the "measuring principle of suspended solid matter"

Pressure equipment functioning on the "measuring principle of suspended solid matter" are intended forcarrying liquid, gaseous and steam media (fluids) and also satisfy the technical measurement task ofmeasuring the operating volumetric flow under constant operating conditions (pressure, temperature,density). The flow measurement can also be output in standard or dimensional units.

Correct usage includes:

• operations within technical limit values.

• compliance with information about the permissible measuring agents (fluids).

• compliance with information about assembly, operations, maintenance etc.

The following are not permitted:

• operation as a flexible adapter in piping, e.g. to compensate for pipe offsets, pipe vibrations, pipe expansions etc..

• use as a climbing aid, e.g. for assembly purposes.

• use as a support for external loads, e.g. as support for piping etc..

• material loss e.g. by drilling the housing or material gain e.g. by painting over the factory panel/type plate or welding on or soldering parts.

• repairs, modifications and supplements or the installation of spare parts is only permitted if under-taken as described in the operating manual. More extensive work must be agreed with us before-hand. We assume no liability for unauthorized work.

The operating, maintenance and repair conditions stated in this operating manual must be observed.

The manufacturer assumes no liability for damage caused by usage which is unprofessional or incorrect.

1.3 Technical limit values

The equipment is only designed for use within the technical limit values specified on the data tag and inthe operating manual. The following technical limit values should be observed:

• the permissible pressure (PS) and the permissible temperature (TS) must be ≤ the pressure and temperature ratings specified in the supplement to this operating manual. The data on the factory tag / the data tag should be observed.

• The maximum and/or minimum operating temperature limits specified in the equipment specification must not be exceeded.

1 Instrument Safety Standards

1.4 Permissible measuring agents (fluids)

• Media may only be used if, depending on state-of-the-art technology or the operating experience of the operator, it can be assured that materials of the components coming into contact with the meas-uring agents (process connection, measurement pipes and flow distributors) assure a minimum of 15 years of successful operation.

• Media with unknown properties may only be used if the operator can perform regular and suitable tests to assure the safe condition of the equipment.

1.5 Safety labels, symbols, data tags, factory tags and CE mark

All safety labels, symbols, the type plate and/or factory panel should be kept legible and replacedif damaged or lost. Note the following general information:

Warning! Warning indicates possible injury to persons which could result in seriousinjury or death. Follow the instructions accurately to protect yourself andothers.

Caution! Caution indicates possible damage to property which could result in incor-rect operation or destruction of the equipment. Follow the instructionscarefully to protect the equipment.

Note! Note indicates important activities or procedures which you MUST under-take correctly in order to prevent interrupts to operation or the function ofthe equipment.

Ex-protec-tion

This symbol identifies equipment with Ex-protection. For usage in Ex-ar-eas, you must observe the information provided in the "Ex-protection"chapter.

CE mark The CE mark indicates that the equipment corresponds to the followingguidelines and satisfies their fundamental safety requirements:

• CE symbol on the type plate (on the measurement transformer)– Conformity with the EMC directive 89/336/EEC

– Conformity with the Ex Directive 94/9/ EC (only for equipment with Ex-protection)

• CE symbol on the factory panel (on the measurement trans-former)– Conformity with the PressureEquipmentDirective (PED) 97/23/EC

The factory panel of pressure equipment does not include the CE mark, ife.g.:

– The max. permissible pressure (PS) is below 0.5 bar.– A registration procedure is not required as a result of the low pres-

sure risks (nominal width ≤ DN 25 / 1").

4.1 Installation Information

Installation should be in accordance with ANSI/ISA RP12.6 "Installation of Intrinsically Safe Systems forHazardous (Classified) Locations" and the National Electric Code® (ANSI/NFPA 70) Sections 504, 505and CEC, Canadian Electrical Code.

4.2 Enclosure Grounding Information

Proper grounding of the AM54 enclosure is important for correct functioning as well as for safety reasons.

For grounding purposes, an AWG#10 (or heavier) copper wire must be connected between the groundingscrew located on the housing and the protective ground.

4.3 Supply Wire Information

Unless otherwise instructed by local or national standards the recommended wire size to be used for sup-ply wire is AWG#20.

4.4 Explosion Proof Installation Information

AM54 Instruments installed using Explosion Proof method of protection in hazardous location groups Aand B must be installed with conduit seals within 18" of the instrument.
