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 measurement types. 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. Digital 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 may be assigned 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

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.

Typical bracket mounted installations

Figure 2: Mounting brackets

Bracket mounting

Mounting bracket, see Figure 3

Rotate the transmitter housing, see Figure 4

Level a transmitter with small absolute or differential pressure spans, see Figure 5

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 screw (1.46 to 1.68 Nm/13 to 15 lb-in).

Figure 4: Rotating Transmitter Housing

Mounting bracket

Position bracket on 2-inch (50.8 mm) and install “U” bolt around pipe and through holes in bracket. Secure with nuts and lock washers provided.

Figure 3 Example - Angle mounting bracket secured to horizontal or vertical pipe.

Figure 3: Angle mounting bracket

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 5: Using level to mount transmitter

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.

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 transmitter by attaching the positive (+) and negative (–) loop wires to the positive (+) and negative (–) terminals on the transmitter terminal block in the electronics housing shown in Figure 8.

Connect the loop power wiring shield to earth ground only at the power supply end.

Supply Voltage for SMV Modbus

Modbus (RS-485) Models: 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 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 device

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 should only be connected to earth ground at the power supply end.

Wiring must comply with local codes, 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 required 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 wiring, detailed 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 wiring.

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 square washer. If multi-stranded wire is used, 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).
