Installing the Sensor Installing the DIN TransmitterInstalling the FM TransmitterBefore You Begin

The EC declaration of conformity, with all applicable European directives, and the complete ATEX Installation Drawings and Instructions are available on the internet at www.micromotion.com/atex

or through your local Micro Motion support center.

2.3 Determining a location

Choose a location for the sensor based on the requirements described in this section. The following general guidelines can help you select an appropriate location for the sensor.

• You should be able to stop flow through the sensor to facilitate the zeroing procedure.

• For optimal performance, the sensor should remain full of process fluid.

• The sensor must be installed in an area that is compatible with the classification specified on the approvals tag (see Table A-4).

2.3.1 Hazardous area installations

Make sure the hazardous area specified on the sensor approvals tag is suitable for the environment in which the sensor is installed (see Table A-4).

LF-Series Flowmeters: Sensor/Transmitter Installation 5

Installing the Sensor

2.3.2 Distance from transmitter

The maximum cable length between the sensor and the transmitter is 1000 ft (300 m). If you are installing the LF-Series sensor for use in an MVD

• The maximum cable length between the sensor and the direct host is 1000 ft (300 m).

• The maximum cable length between the sensor and the power supply depends on the wire size, as shown in Table 2-1. The wire must be sized to provide a minimum of 15 V at the sensor. See the discussion in Section 5.4.1.

Tabl e 2-1 Power supply wire size and cable length – MVD Direct Connect installations

™

) 500 ft (150 m)

Direct Connect™ installation:

Micro Motion supplies 4-wire cable to connect the sensor to the transmitter or remote host. The cable is fitted with a Eurofast ranging from 6.5 ft (2 m) to 500 ft (150 m). For longer cable lengths, contact the factory.

2.3.3 Pipe run

Micro Motion sensors do not require a straight run of pipe upstream or downstream.

2.3.4 Shutoff valve

After the sensor and transmitter have been installed, you must perform the zeroing procedure. During the zeroing procedure, flow through the sensor must be halted and the sensor tubes must be completely full of process fluid. A shutoff valve, downstream from the sensor, is recommended to halt flow during the zeroing procedure. For more information about zeroing, refer to the instruction manual shipped with the transmitter.

2.4 Orienting the sensor

The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid.

2.4.1 Flow direction arrow

The sensor has a flow direction arrow to help you configure the transmitter for flow direction. If possible, install the sensor so that the flow direction arrow matches actual process flow.

2.6 Grounding the sensor

The sensor’s mounting plate must be grounded to earth.

Improper grounding could cause measurement error.

To reduce the risk of measurement error:

• Ground the flowmeter to earth, or follow ground network requirements for the facility.

• For hazardous area installations in Europe, refer to standard EN 60079-14 if national standards do not apply.

If national standards are not in effect, follow these grounding guidelines:

• Use copper wire, 14 AWG (2,5 mm

• Keep all ground leads as short as possible, less than 1 Ω impedance.

• Connect ground leads directly to earth, or follow plant standards.

5.4 MVD Direct Connect wiring

Note: This section applies only to LF-Series sensors used in MVD Direct Connect installations.

Note: MVD Direct Connect installations based on the LF-Series sensor cannot include the MVD Direct Connect I.S. barrier.

In MVD Direct Connect installations, you must connect the sensor to a remote host and to a power supply.

5.4.1 Power supply requirements

The power supply must meet the following requirements:

• Power must be supplied from a common floating regulated power supply with the correct voltage.

• The voltage requirement for a single sensor is 15–26 VDC. The maximum power consumption of a single sensor is approximately 3 W.

• The power supply may be used to power any number of sensors, but must not be used to power other devices.

• Use shielded wiring.

• The power supply must not allow power surges or conducted radio frequency interference (RFI) to propagate through to its output.

• The power supply must not be grounded.

CAUTION

Grounding the power supply to the sensor can cause damage to the sensor or the remote host.

To avoid damaging the sensor or the remote host, ensure that the power supply to the sensor is not grounded.

• In EU countries, the power supply must meet the requirements of the EMC directive.

• The power supply cable must comply with the size and length requirements listed in Table 2-1. A minimum DC input of 15 V is required for each sensor. At startup, the power source must provide a minimum of 0.2 A of short-term current per sensor. The maximum steady state current is 0.15 A. For assistance in sizing the power supply cable, refer to Table 5-1 and use the equation below:

I/O Wiring – FM CIO Transmitters

7.1 Overview

This chapter explains how to wire outputs for LF-Series field-mount CIO transmitters. If you don’t know your transmitter type, see Section 1.6.

It is the user’s responsibility to verify that the specific installation meets the local and national safety requirements and electrical codes.

7.2 Channel configuration

The six output terminals are divided into three pairs. The pairs are called Channels A, B, and C. Channel A is terminals 1 and 2; Channel B is terminals 3 and 4; and Channel C is terminals 5 and 6. Variable assignments are governed by channel configuration.

Output wiring requirements depend on how you will configure the transmitter channels. The configuration options are shown in Table 7-1 and Figure 7-1. You can use a HART Communicator or ProLink II software to configure channels. See the transmitter configuration manual for more information.

I/O Wiring – FM AN I/O Wiring – FM FB and PAI/O Wiring – FM CIOSensor Wiring

If Channel B is configured as a frequency output or discrete output, it can also be configured to use either internal or external power. Channel C can be configured to use either internal or external power, independent of its output configuration.

• “Internal power” means that the terminals are powered automatically by the transmitter. The output wiring instructions do not include power setup and power wiring.

• “External power” means that the terminals must be connected to an independent power supply. The output wiring instructions include power setup and power wiring.

Note: The terms “active” and “passive” are sometimes used to describe internally and externally powered outputs.

Note: You cannot configure the following combination: Channel B = discrete output, Channel C = frequency output. If you need both a frequency output and a discrete output, use the following: Channel B = frequency output, Channel C = discrete output. For more information, see the transmitter configuration manual.

7.4 Frequency output wiring

Frequency output wiring depends on whether you are wiring terminals 3 and 4 (Channel B) or terminals 5 and 6 (Channel C), and also on whether you have configured the terminals for internal or external power. The following diagrams are examples of proper wiring for these configurations:

• Channel B, internal power – Figure 7-5

• Channel B, external power – Figure 7-6

• Channel C, internal power – Figure 7-7

• Channel C, external power – Figure 7-8

Note: If both Channel B and Channel C are configured for frequency output, the Channel C signal is generated from the Channel B signal, with a user-specified phase shift. The signals are electrically isolated but not independent. This configuration is used to support dual-pulse and quadrature modes. For more information, see the transmitter configuration manual.

I/O Wiring – DIN CIO Transmitters

10.1 Overview

This chapter describes how to wire the inputs and outputs for LF-Series DIN CIO transmitters. If you don’t know your transmitter type, see Section 1.6.

It is the user’s responsibility to verify that the specific installation meets the local and national safety requirements and electrical codes.

10.2 Channel configuration

The six output terminals are divided into three pairs. The pairs are called Channels A, B, and C. Channel A is terminals 21 and 22; Channel B is terminals 23 and 24; and Channel C is terminals 31 and 32. Variable assignments are governed by channel configuration.

Output wiring requirements depend on how you will configure the transmitter terminals. The configuration options are shown in Table 10-1 and Figure 10-1. You can use ProLink II software to configure the channels. See the transmitter configuration manual for more information.

I/O Wiring – DIN CIO Return PolicySpecificationsI /O Wiring – DIN AN

• “Internal power” means that the terminals are powered automatically by the transmitter. The output wiring instructions do not include power setup and power wiring.

• “External power” means that the terminals must be connected to an independent power supply. The output wiring instructions include power setup and power wiring.

Note: The terms “active” and “passive” are sometimes used to describe internally and externally powered outputs.

(1) The Bell 202 signal is superimposed on the mA output. (2) Can be configured for active high or active low polarity. Default is active high. (3) You must provide power to the outputs when a channel is set to external power. (4) Because discrete output 1 uses the same circuitry as the frequency output, it is not possible to configure both a frequency

ouput and discrete output 1. If both a frequency output and a discrete output are required, configure Channel B as the frequency output and Channel C as the discrete output (discrete output 2).

(5) When configured for two frequency outputs (dual pulse), frequency output 2 is generated from the same signal that is sent

to the first frequency output. Frequency output 2 is electrically isolated but not independent.

(1) Volume measurement is based on a process-fluid density of 1 g/cm3 (1000 kg/m3). For fluids with density other than 1 g/cm3, the

volumetric flow rate equals the maximum mass flow rate divided by the fluid’s density.

(2) Micro Motion has adopted the terminology “nominal flow range.” The upper limit of this range is the flow rate at which water at

reference conditions causes approximately 15 psid (1 bar) of pressure drop.

- Om ”cirkulär”-typskontakter används skall de vara skärmade

med metallskärm. Om tillämpligt måste kabelförskruvningar med metallskärmsklämmor användas.

- Kabelskärmen skall avslutas mot jord.

• En användarlevererad brytare måste installeras i strömförsörjningsledningen nära transmittern.

• När kabelingångar används skall de uppfylla artikel 7.2.6 i EN 50021.

• I en omgivningstemperatur lägre än –20 °C, skall kabel och kabelingångar eller skyddsrör lämpliga för detta tillstånd användas.

• En typ av skyddskapsling på minst IP 54 enligt EN 60529 uppnås bara när kabel- och skyddsrörsingångar som ger IP 54 enligt EN 60529 används.

• Locket till kopplingsplinten med kontakterna 1–6 kan tas bort korta perioder när apparaten servas för att tillåta kontroll eller justering av strömsatta energibegränsade kretsar.

• När flera transmittrar är staplade på en enkel DIN-skena och omgivningstemperaturen är över 45 °C, måste enheterna sitta minst 10 mm från varandra.

• När temperaturen under nominella prestanda är högre än 70 °C vid kabeleller skyddsrörsingången eller 80 °C vid ledarnas förgreningspunkt skall temperaturmärkdata för kabeln som används mellan sensor och transmitter vara högre än de faktiskt uppmätta temperaturvärdena.

• Åtgärder skall vidtas för att förhindra att märkspänningen överskrids av transientstörningar på mer än 40 %.
