1.8 Human-Machine Interface (HMI) Module
The flow computer includes an HMI module with an optional liquid crystal display (LCD) for local
operator access to the device. The LCD, if present, shows a series of menus that sequentially
displays the current values of particular process variables. A configuration parameter in
FBxConnect determines whether you must first log in to view the menus. If required, you log in by
selecting alphanumeric characters by scrolling through a list until you select the correct character.
The HMI module includes four LEDs to provide status information. Units with the display include
four infrared (IR) buttons for operator interaction.
To conserve power the HMI module enters sleep mode after a period of inactivity. Sleep mode
disables FBxWifi communication. In FBxConnect, you can configure the number of minutes of
inactivity triggering sleep mode through the LCD Sleep Time parameter. Setting this parameter to
0 disables sleep mode which keeps the HMI module on but uses significantly more power.
Figure 1-4. HMI Module with LCD
Figure 1-5. HMI Module without LCD
Note
If your flow computer does not include the LCD option (shown in Figure 1-4), you still have the
status LEDs and a single IR button for waking up the device (shown in Figure 1-5).
1.9 FBxWifi™ Communications
The flow computer has an optional Wi-Fi® transceiver (FBxWifi) that enables you to connect via a
laptop or tablet from a distance. The distance supported varies depending on the laptop/tablet
8 Introduction
type and environmental conditions but is typically 70 to 100 feet from the front of the flow
computer and 40 to 60 feet from the side and rear of the flow computer.
This capability allows an operator to potentially remain outside the hazardous location and still
communicate with the flow computer. The operator's laptop must have Wi-Fi capability, line-ofsight access to the HMI module, and must be loaded with FBxConnect configuration software.
Once connected, the operator can view process values, edit configuration parameters, and collect
logs.
Note
The FBxWifi electronics reside inside the HMI module. The HMI module must be awake to use
FBxWifi communications You can wake it up manually by holding a finger against the front cover
glass over the Hold to Wake button (the left-most button) for typically from five to ten seconds.
1.10 Software Tools
The FBxConnect configuration software provides a series of wizards that allow you to perform
configuration activities for the flow computer. You connect a PC running the FBxConnect
configuration software to the flow computer using one of the communication ports or through a
wireless connection. You can then:

Holes in the door latches of the fiberglass enclosure allow you to attach a wire seal.
Alternatively, you can use a pan head screw (#10-32 X 0.81 316 SS or Monel alloy 400) with an Oring (0.15 ID, 0.07 W) in place of one or both door latches to screw the door shut. In this case, you
pry off the latch with a flat head screwdriver and pop out the mating cap to free up the holes for the
screw.
Figure 1-7. Removing Cap and Latch from Fiberglass Enclosure
For ATEX/IEC-compliant installations with the fiberglass enclosure, you must use one of these three
choices (padlock, wire seal, or screw).
For either enclosure type, you may apply tamper-evident tape to the four sensor coupling screws
and two rotation set screws to provide evidence of unauthorized sensor adjustments. The four
coupling screws also include holes through which you could attach a wire seal.

The flow computer’s pluggable terminal blocks use compression-type terminals that
accommodate wire between 28 and 12 AWG.
When making a connection, insert the bare end of the wire (approx. 1/4" max) into the clamp
adjacent to the screw and secure the screw.
To prevent shorts, ensure that no bare wire is exposed.
Allow some slack in the wire while making terminal connections. Slack makes the wires more
manageable and helps minimize mechanical strain on the terminal blocks.
Use twisted pair, shielded and insulated cable for communication and I/O wiring to minimize
signal errors caused by electromagnetic interference (EMI), radio frequency interference
(RFI) and transients. When using shielded cable, ground all shields at only one point in the
appropriate system. This prevents circulating ground current loops that can cause signal
errors.
20 Installation
2.6 Grounding
The flow computer includes a ground stud on the bottom of the battery compartment
Figure 2-7. Ground Stud
Once you have installed the unit, run a ground wire between the ground stud on the
bottom of the battery compartment and a known good earth ground. You route the
ground wire through one of the conduit fittings.
Use stranded copper wire to earth ground and keep the length as short as possible.
Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
For more information on grounding or if your installation uses cathodic protection, refer to Site
Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).

2.9 Power Modes
To keep power consumption to a minimum, especially for remote sites, the FB2200 can run in two
different power modes – Low Power Mode (4 MHz or 8 CPU MHz clock speed) or Standard Power
Mode (60 MHz CPU clock speed).
Low Power Mode
The FB2200 normally runs in low power mode for typical metering applications. The radio Power
Control function (configurable in FBxConnect) switches the flow computer into standard power
mode at specific times when serial communications are required, then it reverts to low power
mode when the communication period is over. A serial connection to a remote 4088B MVT can
occur in low power mode.
The local display (HMI module) with FBxWifi uses additional power. You can configure it in
FBxConnect to shut down after a period of inactivity.
Important
You must disable the Ethernet port (using a jumper) to run in low power mode. See Section 2.13.3.

Point the solar panel surface due south (in the northern hemisphere) or due north (in the
southern hemisphere) at an angle determined by the latitude of the site. Table 2-8 shows the
angle (from horizontal) at which you should install the solar panel to maximize annual energy
output. At most latitudes, you can improve performance by reducing the angle during the
summer and increasing the angle during the winter. If no seasonal adjustments in panel
direction are needed, then adjust the position for the worst-case December-February angle.
Solar insolation is the amount of solar energy in hours received each day by an optimally
tilted panel during the worst month of the year. An insolation rating of one hour means that
the site, on average, would receive one hour of solar energy at the panel's rated power level

I/O in the FB2200 flow computer comes from the integrated multivariable sensor and RTD
connector, the CPU board, as well as the optional mixed I/O modules.
Note
When using a digital output to drive an inductive load (such as a relay coil), place a suppression
diode across the load. This protects the DO from the reverse Electro-Motive Force (EMF) spike
generated when the inductive load is switched off.
Notes About Power for an External Device Connected to a Flow Computer I/O Point:
If the external device does not include its own integrated power supply, you must provide your own
external supply (30Vdc maximum) for that device.
If your FB2200 flow computer includes the optional 8-channel Expansion I/O Module, you may be
able to use the 24V loop power terminals to power the external device. In this case, the
load current
cannot exceed 500 mA.

3.8 Wiring a Digital Output to the Optional Relay
The flow computer supports two optional electro-mechanical relays for switching on/off external
circuits or devices. If you order this option, the relays ship from the factory mounted to the top of
the battery compartment inside the flow computer enclosure.
You can wire a relay to an isolated DO (Figure 3-18). You must also use the isolated GND and
provide 24V to power the relay. To attach a wire, insert it into the connector and tighten the
adjacent screw to secure it. The NO and COM wires go to the external circuit or device.
Figure 3-18. Relay Wired to Isolated DO
D301784X012

Alternatively, you can wire a relay to a non-isolated DO (Figure 3-19). In that case, you must use the
non-isolated GND and provide 24V to power the relay. To attach a wire, insert it into the connector
and tighten the adjacent screw to secure it. The NO and COM wires go to your external circuit or
device.

Communicating using the HMI Module
This section describes day-to-day operation of the flow computer including how to turn it on and
off and how to communicate with it.
4.1 Powering Up/Powering Down the Device
D301784X012
November 2020
DANGER
Do not attempt to connect or disconnect power from the unit in a hazardous area. Ensure the
area is non-hazardous. Failure to do so could result in an explosion.
1. Open the enclosure door.
2. Terminal block TB2 (pins 1,3,5,7) includes connections for DC power (DCIN+, DCIN-) and
battery/ solar power (BATT+, BATT-). The internal battery (which is also used with solar
power) has its own internal connectors.
This turns on (or shuts OFF) power from either an external power supply or the battery
pack/solar panel.
Note
When you turn power on, the backlight on the HMI module lights, momentarily turns off and then
remains lit while the INPUT LED blinks. After approximately one minute the initialization process
finishes and the HMI starts to display live data.
Plug in TB2 (pins 1,3,5,7) to activate DC or battery/solar power. If your device uses an
internal battery and it is not connected, connect it as discussed in 2.8.3 Connecting
Battery Power.
Unplug TB2 (pins 1,3,5,7) to deactivate DC or battery/solar power.
4.2 Establishing Communications
The flow computer supports three ways to establish communications: through the host SCADA
system, through a local laptop computer running FBxConnect, or through the HMI module.
4.2.1 Communicating with the SCADA Host
Communication to the flow computer through a SCADA host computer requires configuration of
the host computer software, which varies depending upon whether you are using OpenEnterprise
or another host software package. Much of this configuration is beyond the scope of this topic, but
no matter which host you are using, there are certain steps you must take:
Operation 83
Emerson FB2200 Flow Computer Instruction Manual
D301784X012
November 2020
1. Decide how the SCADA host should communicate with the flow computer. This could be
through connection with one of the communication ports. A serial port connection could be
a cable directly connected to the SCADA host or there could be intermediate connections
through a radio or modem.
2. Decide which communication protocol you will use. This could be DNP3, ROC, Modbus, or
BSAP. See these documents for more information:
DNP3 Protocol Specifications Manual (for FB1000 and FB2000) (D301806X012)
ROC Protocol Specifications Manual (for Emerson FB Series Flow Computers)
(D301828X012)
FBxConnect Configuration Software User Manual (D301850X012)
BSAP Communication Guide for FB1000/FB2000 Series Flow Computers (D301808X012)
3. Provide the SCADA host with information about the various parameters it needs to extract
from the application running in the flow computer. Typically, the SCADA host software
includes a utility that allows you to identify this information so it can be incorporated into the
database at the SCADA host.
4. Using whatever human-machine interface (HMI) tools exist for the SCADA host, create
graphical displays or reports that include the parameters from the application required for
successful operator interaction (setpoints, flow variables and so on).
4.2.2 Communicating with a Laptop Using One of the Serial Ports
If the flow computer is not awake, you must wake it up first. (See Section 4.3)
Your laptop must have Field Tools software with FBxConnect software installed.
You must know a valid username/password combination for the flow computer.
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
1. Connect a cable between a serial port (or serial/USB adapter) on your laptop and port COM2
on the flow computer.
2. Launch Field Tools and add a new serial connection for this device; this launches FBxConnect
configuration software. (If you already have an existing saved serial connection for this
device in Field Tools, just double-click on it in the Connections list.)
3. Log into the flow computer if prompted.
4. Use the FBxConnect configuration software to view or change any desired parameters.
5. When finished, log off the flow computer and disconnect the cable from its serial port.
4.2.3 Communicating with a Laptop Using Ethernet
Your laptop must have Field Tools software with FBxConnect software installed. Additionally, you
must know a valid username/password combination for the flow computer. :

4.3 Communicating Using the HMI Module
You must have purchased the flow computer with the HMI module version that includes the
optional display. Not all models include the display. Units without the display still include a button
to wake up the device and status LEDs.
Notes:
If the device is configured to require logins to view data, you must know a valid
username/password combination for the flow computer.
To conserve power, the HMI module enters sleep mode after a period of inactivity. Sleep mode
disables FBxWifi communication. In FBxConnect, you can configure the number of minutes of
inactivity triggering sleep mode through the LCD Sleep Time parameter. Setting this
parameter to 0 disables sleep mode which keeps the HMI module on but uses significantly
more power.
To temporarily keep the HMI module out of sleep mode, maintain an active FBxConnect
connection. As long as communications remain active, the HMI module will not sleep
1. Go to the front of the flow computer and touch your finger on the glass above the Hold to
Wake button until the display lights up. (This may take several seconds.)

Removing/Replacing the HMI Module
Replacing the Main Battery Pack
Removing/Replacing the SRAM Battery
Upgrading System Firmware
In order to maintain hazardous location certifications, you can only replace components in the field
with the exact same part so that the model string on the data plate remains correct. This means
you cannot add any hardware not reflected in the model string or upgrade a hardware component
to a newer version; any such upgrades are prohibited and void the hazardous location certification.
This chapter describes the service tasks that everyone needs to know such as replacing batteries or
installing a firmware upgrade. For other field replacements, see the appropriate field replacement
guides for that component. Any replacement not covered in this chapter or in the field
replacement guides can only be performed at an Emerson-authorized repair facility.
Important
Use only batteries supplied with the flow computer or sold by Emerson Remote Automation
Solutions as spare parts for this flow computer. If you substitute a battery you obtain elsewhere you
will void your certification unless it is the identical part from the same manufacturer as that supplied
with the flow computer from Emerson.

5.1 Returning the Unit for Repairs
Only certain field replacement procedures are allowed under warranty and hazardous location
certification. Other types of repairs cannot be performed in the field. In those cases, you must ship
the unit to an Emerson-authorized repair facility. Contact Emerson Remote Automation Solutions
for a return authorization number and instructions for where to ship the unit.
International safety regulations restrict the shipment of lithium batteries. If you need to return
the flow computer, remove the lithium battery before you ship the unit. Failure to remove the
lithium battery may delay or prevent shipment of the flow computer.
5.2 Interpreting the Status LEDs
There are four (4) status LEDs on the flow computer. The meaning of each LED varies depending
upon the color displayed or whether the LED flashes.
