CE Conformity (Europe) Notice for Remote Meter Assemblies

(RMA)

About Conformity and Special Conditions

This product is in conformity with the protection requirements of 89/336/EEC, the EMC Directive, and of
94/9/EC, the Explosive Atmospheres (ATEX) Directive. Conformity of this product with any other “CE

Mark” Directive(s) shall not be assumed.
Deviation from the installation conditions specified in this manual, and the following special conditions,

may invalidate this product’s conformity with the EMC Directive.

• Shielded, twisted-pair cable such as Belden 9318 must be used for all signal/power wiring.

• The shield must be connected to ground at only one end of the cable. Connect it to the power supply and

the meter sides of the wiring; leave the shield insulated at the transmitter side of the wiring.

ATTENTION

The emission limits of EN 50081-2 are designed to provide reasonable protection against
harmful interference when this equipment is operated in an industrial environment. Operation
of this equipment in a residential area may cause harmful interference. This equipment
generates, uses, and can radiate radio frequency energy and may cause interference to radio
and television reception when the equipment is used closer than 30 meters (98 feet) to the
antenna(e). In special cases, when highly susceptible apparatus is used in close proximity, the
user may have to employ additional mitigating measures to further reduce the electromagnetic
emissions of this equipment.

RMA 3000 Description

Function and Design

The Honeywell RMA 3000 Remote Meter Assemblies provide various means of remote-mounting a meter
that is associated with a Honeywell SmartLine transmitter or a compatible non-Honeywell transmitter.

The RMA 3000 includes a remote meter housing that can be used in hazardous environments or in ordinary
environments. When used in hazardous environments, the remote housing must be configured as a
flameproof/explosion-proof housing, in which all points of entrance and exit for wiring are protected and
sealed via rigid metal conduit or suitable cable gland fittings.

Two meter styles are available, and with a few exceptions any of these may be connected in either of two
basic physical/wiring configurations, as indicated in Figure 1.

Figure 1: Overview of RMA Configuration

Release 8 RMA 3000 Remote Meter Assemblies User Manual 9

That is, the explosion-proof housing may be located

- at the end of a wiring run for the transmitter loop, or

- between the transmitter and the receiver devices.
This manual includes several sets of Honeywell-certified engineering drawings that specify RMA 3000

configurations and conditions that are approved for use in hazardous environments by various approval
agencies (FM, CSA, and LCIE (ATEX). Each of these drawings shows a configuration similar to that
shown in Figure 1; that is, a single meter connected remote from a single transmitter.

In some selected cases (such as operation in non-hazardous locations), it is possible to connect more than
one meter to a given transmitter. In these cases, the additional meter(s) may be placed either at the end of a
wiring run, or at any location between the transmitter and other elements of the Remote Meter Assemblies
configuration.

The number of meters that may be incorporated depends on the circuit configuration and on electrical
characteristics of associated equipment. For more information regarding the use of multiple remote meters
with a single transmitter, refer to the descriptions under the heading Multiple Remote Meters.

Meter Types - Options

Remote Meter Assemblies provide for two meter types. The features of each are highlighted in Figure 2,
and are described after the figure below.

Figure 2: Highlights of Meter Features

ME – Analog Meter

Function - The ME is an analog device that functions as an output indicator for any transmitter that
operates in the 4-20 mA current mode.

Application - The ME can be used as a Remote Meter Assembly component with any one of the
following SmartLine transmitters operating in the analog (4 to 20 mA) mode.

Electrical Characteristics – The ME is an electromechanical device of the D’Arsonval type. That is,
the current passing through a coil in the meter is used to deflect a needle to indicate the magnitude of the
current, where a current of 4-20 mA represents 0% to 100%.

The ME can be used in combination with the SM in the same loop, provided that the formula presented
under the SM description above in electrical characteristics for multiple meters is obeyed.

10 RMA 3000 Remote Meter Assemblies User Manual Release 8

EU – Engineering Units Meter

The Engineering Units Meter (EU) is described briefly here only in the context of RMA 3000 application
and installation. For detailed information such as digital display features, installation, set up and operation,
refer to

34-ST-25-18 Engineering Unit Meter User’s Guide.

Function - The Engineering Unit Meter is an LCD indicator that provides a digital display of a

transmitter’s output PV when connected in a 4 to 20 mA analog loop. The meter is compatible with

Honeywell SmartLine transmitters operating in analog mode and with other non-Honeywell transmitters
operating in a 4 to 20 mA current loop.

Description - The EU meter is designed to provide a simple indication of a transmitter’s output value. A
multi-segmented LCD display is encased in a circular black plastic frame for local installation to the
transmitter. A printed circuit assembly (PWA) is mounted behind the display and contains the electronics
and wire connections for the meter. The EU meter is powered from the transmitter loop current. A
momentary contact toggle switch is mounted on the PWA and is used for setting up and verifying the
display indication.

Installation in Hazardous Locations

For installation in hazardous locations, the RMA 3000 must be configured and installed as detailed in the
appropriate Honeywell-certified engineering drawing(s), which conform to practices specified by various
approval agencies. Installation requirements vary somewhat among approval agencies.

Wiring-Port Seals at Remote Housing

When used in hazardous environments, the remote housing may be configured as a flameproof/explosion­proof housing, in which all points of entrance and exit for wiring are protected and sealed via rigid metal
conduit or suitable cable gland fittings.

Examples of metal conduit fittings are shown in Figure 3, and an example of a sealed cable gland is shown
in Figure 4.
