DANGER
When installing units in a hazardous area, make sure all installation
components selected are labeled for use in such areas. Installation and
maintenance must be performed only when the area is known to be non-hazardous.
Installation or maintenance in a hazardous area could result in personal
injury or property damage.
Always turn off the power to the FB1200 before you attempt any type of wiring.
Wiring of powered equipment could result in personal injury or property
damage.
To avoid circuit damage when working inside the unit, use appropriate
electrostatic discharge precautions, such as wearing a grounded wrist strap.
Check the input power polarity before connecting power to the FB1200. Wiring
of powered equipment could result in personal injury or property damage.
The following tools are required for installation, maintenance, and troubleshooting:
- Personal computer running Microsoft® Windows® 7 Professional or Windows 8.1 Pro, or Windows 10 Pro and Emerson Field Tools configuration software (providing FBxConnect™).
-
1 and #2 Phillips (cross-head) screwdrivers.
- 3 mm (1/8-inch) flat-head screwdriver.
- Torque wrench.
- 14 mm (9/16-inch) and 10 mm (3/8-inch) hexagonal wrenches.
Unpacking
You receive the FB1200 in a box. Remove it from the box. Examine the packing
list carefully to ensure you have all components.
Installation
- Find a suitable location for the FB1200. When selecting an installation site, be sure to check all clearances. The FB1200 housing is designed to withstand a variety of inclement conditions. The optional LCD should be visible and accessible for the on-site operator.

- The FB1200 mounts either directly to a manifold on the pipeline or indirectly on a two-inch pipe or pole. See Figures 6 and 7.

Grounding
Remove the front and rear covers of the FB1200 as detailed in either Chapter 2
of the Emerson FB1200 Flow Computer Instruction Manual (part D301782X012) or
in the Emerson FB1200 Flow Computer Quick Start Guide
(part D301786X012). Store the covers in a secure location.
If your company has no specific grounding requirements, install the FB1200 as
a “floating”
(unconnected to ground) system using the ground lug and routing the ground
wire through one of the conduit fittings. Otherwise, follow your company’s
specific grounding practices. However, if you are making a connection between
a grounded device and an EIA-232 (RS-232) port, ground the FB1200’s power
supply.
If you must ground the equipment, observe the following guidelines:
-
When the equipment uses a DC voltage source, the grounding system must terminate at the service disconnect. All equipment grounding conductors–including wire or conduit carrying the power supply conductors–must provide an uninterrupted electrical path to the service disconnect.
-
Improper grounding or poor grounding practices can often cause problems, such as introducing ground loops into the system. Properly grounding the FB1200 helps to reduce the effects of electrical noise on the unit’s operation and protects against lightning. Install a surge protection device at the service disconnect on DC voltage source systems to protect the installed equipment against lightning and power surges.
-
Ensure that the flow computer’s ground is
separate from the cathodic protection ground. -
The grounding installation method for the FB1200 depends on whether the pipeline has cathodic protection. On pipelines with cathodic protection, electrically isolate the FB1200 from the pipeline. All earth grounds must have an earth-to-ground rod or grid impedance of 25 ohms or less, as measured with a ground system tester.
Wiring to Power
Review the power wiring descriptions in Chapter 2 of the Emerson FB1200 Flow
Computer Instruction Manual (part D301782X012). Wire the FB1200 through the
conduit fittings on the side of the housing. The terminal blocks accept 2mm in
diameter/3mm2 or smaller wiring. To connect the wire to the removable block
compression terminals:
- Bare the end (6mm maximum) of the wire.
- Insert the bared end of the wire into the clamp beneath the termination screw.
- Tighten the screw.
Expose a minimum of bare wire to prevent short circuits. Allow some slack when making connections to prevent strain.
Verify the hook-up polarity is correct.
To make DC power supply connections:
- Optionally, install a surge protection device at the service disconnect.
- Install a fuse at the input power source.
- Remove the terminal block connector from the socket.
- Insert each bare wire end into its appropriate connector and secure the wire (see Figures 8 and 9).
- Plug the terminal block connector back into the socket.
Figure 8. Wiring to DC Power Supply (with Optional I/O)
Figure 9. Wiring to DC Power Supply (without Optional I/O)
Wiring to Communications & I/O
Connect the wiring to the terminal blocks on the I/O and communications
modules. Refer to either Section 2.13 in Chapter 2 of the Emerson FB1200 Flow
Computer Instruction Manual (part D301782X012) or the Emerson FB1200 Flow
Computer Quick Start Guide (part D301786X012) for wiring schematics and
explanations.
Once you have wired the communications and I/O, replace the front and rear
covers of the FB1200.
Powering Up the FB1200
DANGER
Do not attempt to connect power 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.
To start up the FB1200, apply power.
When you turn power on, the backlight on the HMI module lights for about 5
seconds, then turns off. During this time the database begins to initialize.
After about 45 seconds the backlight on the HMI turns on again and starts to
display live data.
Periodically inspect the wiring for signs of deterioration.
Configuring the FB1200
You must install Emerson’s Field Tools configuration software (which includes
FBxConnect™) on your PC to configure the FB1200 for use. Refer to the Emerson
FB1200 Flow Computer Quick Start Guide (part D301786X012) for instructions on
installing and using this software.
Resetting the FB1200
If you are experiencing problems that appear to be software related, try
resetting the FB1200. Refer to the Service and Troubleshooting chapter of the
Emerson FB1200 Flow Computer Instruction Manual (part D301782X012) for
specific instructions.
Note: You lose all configuration and log data with a reset. If possible, make a backup of configuration and log data before attempting any type of reset.
Replacing Parts in the FB1200
Refer to Table 1 for a list of user-serviceable parts and their respective
Field Replacement Guides.
Returning the FB1200
If you are experiencing problems that appear to be hardware-related, verify
the wiring. If you still experience problems, contact your local sales office
for return authorization. To return the device:
- Back up all configuration and data before removing the device from process. Then remove power from the device and remove all external wiring.
- Uninstall the device.
- Place the device into a box safe for shipping or storage.
