Installation

Evaluate the site selected for the transmitter installation with respect to the process system design specifications and Honeywell’s published performance characteristics for your model. Temperature extremes can affect display quality. The display can become unreadable at temperature extremes; however, this is only a temporary condition. The display will again be readable when temperatures return to within operable limits.

Features and Options

The SMV800 is packaged in two major assemblies: the electronics housing and the meter body. The elements in the electronic housing respond to setup commands and execute the software and protocol for the different pressure m eas urem e nt t ypes. Figure 1 shows the assemblies in the electronics housing with available options. The meter body provides connection to a process system. Several physical interface configurations are available, as determined by the mounting and mechanical connections.

The SMV800 SmartLine multivariable transmitter measures differential pressure, static pressure (absolute or gauge), and process temperature. These measurements are used to calculate volumetric or mass flow rates. The measured values and calculated flow can be read by a connected Host. Available communication protocols are Honeywell Digitally Enhanced (DE), HART and Modbus RTU. Digi tal or analog (4-20ma) output modes are available. The SMV800 measures process temperature from an external RTD or thermocouple. Universal temperature input is available as a selectable feature with the device or as license enabled, field upgradable option. With Modbus protocol, Flow calculation capability also is available as selectable feature with the device or as license enabled, field upgradable option while this is a standard feature with HART and DE protocols

Device Variables

SMV800 supports 6 device variables:

1. Differential Pressure

2. Static Pressure

3. Process Temperature

4. Calculated Flow Rate

5. Totalizer

6. Meter Body Temperature.

For DE transmitters, Differential Pressure, Static Pressure, Process Temperature or Flow ma y be assig ne d to analog output. In HART transmitters, Differential Pressure, Static Pressure, Process Temperature, Flow and Totalizer may be mapped to device variables PV (analog output), SV, TV or QV and Meter Body temperature may be mapped to SV, TV or QV. All six variables are Modbus process variables.

Mounting the Transmitter

Mounting bracket

Transmitter models can be attached to a two-inch (50 millimeter) vertical or horizontal pipe using Honeywell’s optional angle or flat mounting bracket; alternately you can use your own bracket.

Rotating Transmitter Housing

Use a 2mm hex wrench to loosen the set screw on outside neck of transmitter one full turn. Rotate the transmitter housing to a maximum of 180 degree increment in left or right direction from center to position you require and tighten set scre w (1. 46 to 1 .68 Nm / 13 to 15 lb-in).

Leveling Transmitters with Small Absolute or Differential Pressure Spans

Mounting position of these transmitters is critical due to the smaller transmitter spans.

To minimize these positional effects on calibration (zero shift), take the appropriate mounting precautions that follow for the given transmitter model.

See figure below for suggestions on how to level the transmitter using a spirit balance.

To perform a Zero Trim after leveling, refer to Trim the Transmitter.

Figure 4: Rotating Transmitter Housing

For a model SMA810 or SMA845 transmitters, you must ensure that the transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-side and front-to-back.

Mount transmitter vertically to assure best accuracy. Position a spirit balance on pressure connection surface of AP body.

Wiring Connections and Power Up

Summary

The transmitter (HART/DE) is designed to operate in a two-wire power/current loop with loop resistance and power supply voltage within the HART/DE operating range shown below.

Supply Voltage for SMV Modbus

Modbus (RS-485) Mod els : 9.5 V to 30 Vdc at terminals. Power Consumption: Average power consumption is 70 mW at 9.5 V

Supply. This includes RS-485 communication at 9600 baud rate at a rate of once per second without termination at room temperature.

Figure 7: Two-wire power/current loop

A minimum of 250 ohms of loop resistance is required to support communications. Loop resistance = barrier resistance., + wire resistance, =receiver resistance, +peripheral device resistance

Loop wiring is connected to the tr ans m i tt er b y attaching the positive (+) and negative (–) loop wires to the positive (+) and negative (–) terminals on th e transmitter terminal block in the electronics housing shown in Figure 8. Connect the loop power wirin g s hield to earth ground only at the power supply end.

Figure 8: Terminal Block and Grounding Screw location

As shown above, each transmitter has an internal terminal to connect it to earth ground. Optionally, a ground terminal can be added to the outside of the Electronics Housing. Screw terminals 1, 2, 3, 5, 6, 7 & 8 only required for single input, terminals 4 and 9 are only used for a Modbus dev ic e

CAUTION: For proper operation of the transmitter, grounding of the transmitter is mandatory. This minimizes the possible effects of noise on the output signal and affords protection against lighting and static discharge

An optional lightning terminal block can be installed in place of the nonlightning terminal block for transmitters that will be installed in areas that are highly susceptible to lightning strikes. As noted above, the loop power wiring shield shoul d onl y be co n nect ed to earth ground at the

Description

Wiring must comply with local co des, regulations and ordinances. Grounding may be required to meet various approval body certification, for example CE conformity. Refer to Appendix A of this document for details.

The HART/DE transmitter is designed to operate in a 2-wire power/current loop with loop resistance and power supply voltage within the operating range; see Figure 7.

With an optional remote meter (for HART/DE), the voltage drop for this must be added to the basic power supply voltage requirements to determine the required transmitter voltage and maximum loop resistance. Additional consideration is required when selecting intrinsic safety barriers to ensure that they will supply at least minimum transmitter voltage, including the re qui r ed 250 ohms of resistance (typically within the barriers) needed for digital communications.

Wiring Variations

The above procedures are used to connect power to a transmitter. For loop wiring and external wi rin g, det ai le d drawings are provided for transmitter installation in non-intrinsically safe areas and for intrinsically safe loops in hazardous area locations.

The screw terminals suitable for wirings up to (16AWG)

- Shielded, twisted-pair cable such as Belden 9318 or equivalent must be used for all signal/power wi rin g. Note: If solid core wire is used strip insulation 1/4 in (6 mm). Once inserted under the square washer the stripped portion should be contained under the squa re was he r. If m ult i-str an de d wir e is use d, a ferrule is to be used and the stripped wire should be in the insulated portion of the ferrule. The ferrule can be also used on the solid core wire.

- The cable shield must be connected at only one end of the cable. Connect it to the power supply side and leave the shield insulated at the transmitter side.

After wiring the Transmitter as outline in the next sections, torque the screws to 1.1 Nm (10 lb-in).

Connect the input sensors as shown in Figure 9 below:

RTD Connections

o Resistance temperature detector (RTD) measurements use the 3 or

4 wire approach. The transmitter determines by itself if a 3 or 4 wire

RTD is connected when powered up.
