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
Automation Solutions Training Department at 800-338-8158 or email us at [e-mail].

Ethernet Connectivity

This automation device is intended to be used in an Ethernet network which does not have public access. The inclusion of this
device in a publicly accessible Ethernet-based network is not recommended.

Replacing the CPU Enclosure & Electronics

You can replace the CPU enclosure and its individual boards in the field provided that the
replacement has the exact same part number and version.

There is considerable overlap between the different field replacement procedures for the items
covered in this guide. This guide presents several discrete tasks which are used, and then
references them in procedures as they are needed.

Restriction

Hazardous area approvals require that any part replaced in the field be the exact same part (“like­for-like”). Upgrading or substituting different parts violates hazardous area certification.

Tip

Because some of these procedures involve removing small parts such as screws and standoffs, we
recommend you provide a container for holding small parts.

Removing/Restoring Main Power

Except when replacing batteries or the HMI module, you must always remove main power when
performing field replacements.

Removing Main Power

Before you begin any of these procedures, you must remove main power. Terminal block TB2 (pins
1,3,5,7) includes connections for DC power (DCIN+, DCIN-) and battery/ solar power (BATT+,
BATT–). The internal battery (used with solar power) also has its own internal connectors inside the
battery compartment.

1. Open the door of the flow computer enclosure.

2. Unplug TB2 (pins 1,3,5,7) to deactivate DC or battery/solar power. This shuts OFF power
from either an external power supply or the internal battery pack/solar panel.

Restoring Main Power

When you are done with all field replacement activities, you can restore main power. Plug in
terminal block TB2 (pins 1,3,5,7) to restore power.

Once you restore main power, close the flow computer enclosure door.

Removing/Replacing the HMI Module

The HMI module attaches to the outside of the CPU enclosure cover.

Removing the HMI Module

1. Use a #1 Phillips-head screwdriver to loosen the four captive fastening screws that attach the

HMI module to the CPU enclosure cover.

Captive Screws

2. Grasp the HMI module and remove it by gently pulling it straight out.

Replacing the HMI Module

1. To replace the HMI module, line up the printed circuit board (PCB) with the slot on the back
and gently press it back on.

2. Tighten the four captive fastening screws with a torque value of 4 to 6 in.-lbs. (0.5 to 0.7 N­m).
