Device Safety Considerations
Reading these Instructions
Before operating the device, read these instructions carefully and understand their safety implications. In some situations,
improperly using this device may result in damage or injury. Keep this manual in a convenient location for future reference.
Note that these instructions may not cover all details or variations in equipment or cover every possible situation regarding
installation, operation, or maintenance. Should problems arise that are not covered sufficiently in the text, immediately
contact Customer Support for further information.
Protecting Operating Processes
A failure of this device – for whatever reason -- may leave an operating process without appropriate protection and could result
in possible damage to property or injury to persons. To protect against this, you should review the need for additional backup
equipment or provide alternate means of protection (such as alarm devices, output limiting, fail-safe valves, relief valves,
emergency shutoffs, emergency switches, etc.). Contact Remote Automation Solutions for additional information.
Returning Equipment
If you need to return any equipment to Remote Automation Solutions, it is your responsibility to ensure that the equipment
has been cleaned to safe levels, as defined and/or determined by applicable federal, state and/or local law regulations or
codes. You also agree to indemnify Remote Automation Solutions and hold Remote Automation Solutions harmless from any
liability or damage which Remote Automation Solutions may incur or suffer due to your failure to ensure device cleanliness.
Grounding Equipment
Ground metal enclosures and exposed metal parts of electrical instruments in accordance with OSHA rules and regulations as
specified in Design Safety Standards for Electrical Systems, 29 CFR, Part 1910, Subpart S, dated: April 16, 1981 (OSHA rulings are
in agreement with the National Electrical Code). You must also ground mechanical or pneumatic instruments that include
electrically operated devices such as lights, switches, relays, alarms, or chart drives.
Important: Complying with the codes and regulations of authorities having jurisdiction is essential to ensuring personnel
safety. The guidelines and recommendations in this manual are intended to meet or exceed applicable codes and regulations.
If differences occur between this manual and the codes and regulations of authorities having jurisdiction, those codes and
regulations must take precedence.
Protecting from Electrostatic Discharge (ESD)
This device contains sensitive electronic components which be damaged by exposure to an ESD voltage. Depending on the
magnitude and duration of the ESD, it can result in erratic operation or complete failure of the equipment. Ensure that you
correctly care for and handle ESD-sensitive components.
System Training
A well-trained workforce is critical to the success of your operation. Knowing how to correctly install, configure, program,
calibrate, and trouble-shoot your Emerson equipment provides your engineers and technicians with the skills and confidence
to optimize your investment. Remote Automation Solutions offers a variety of ways for your personnel to acquire essential
system expertise. Our full-time professional instructors can conduct classroom training at several of our corporate offices, at
your site, or even at your regional Emerson office. You can also receive the same quality training via our live, interactive
Emerson Virtual Classroom and save on travel costs. For our complete schedule and further information, contact the Remote

Removing/Replacing the Relay
The FB2100/FB2200 Flow Computer supports an optional electro-mechanical relay for switching
on/off an external circuit or device. The relay mounts to the top of the battery enclosure. In all
cases, the relay requires 24V power. You can wire it to either an isolated or non-isolated digital
output (DO), but you must use the appropriate ground for either isolated or non-isolated.
Refer to the table below for the correct field replacement part number.
Electro-mechanical Relay 395828-01-0
Ambient Temperature Range
May be used up to a maximum ambient temperature of 70°C and a minimum ambient temperature
of –40°C; refer to the data plate attached to the device for ambient temperature.

2. Gently slide the tip of a flat head screwdriver between the relay and the top of the battery
enclosure.
3. Move the screwdriver tip to either side of the relay and press down gently on the screwdriver
handle to apply upward pressure on one side of the relay so that it moves slightly up the
relay mounting bracket.

4. Repeat this process on the other side of the relay and continue alternating between the sides
to gradually work the relay up and off of the relay mounting bracket.
5. Remove wires from the old relay and then attach them to the new (replacement) relay. (See
Wiring the Relay to an Isolated DO or Wiring the Relay to a Non-Isolated DO as appropriate to
the type of digital output you want to use.)
6. Once you finish wiring to the new relay, slide it across the top of the battery enclosure and
hook the non-flexible tab onto the relay mounting bracket.

Wiring the Relay to an Isolated DO
You can wire the relay to an isolated DO. 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.
Wiring the Relay to Non-Isolated DO
Alternatively, you can wire the relay to a non-isolated DO. In that case, you must use the nonisolated 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.
