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.

Safety First!

Never perform the installation/setup activities described in this document in a hazardous area. Ensure the area is non-hazardous.

DANGER

EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in a hazardous location could result in an explosion.

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.

Important

Use only batteries supplied with the flow computer or sold by Emerson 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.

Removing the Front or Rear End Cap

The flow computer includes two threaded end caps (covers). The front end cap includes a window for viewing the HMI module, while the rear end cap provides access to the terminal plate for power and I/O wiring.

DANGER

EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in a hazardous location could result in an explosion.

1. Remove the retaining clamp (if present). Grasp the end cap (front or rear).

Note

If you need more leverage to open or close an end cap than you can get with your hand, you can place a long screwdriver or other appropriate tool across the two notches in the end cap to act as a pry bar:

2. Unscrew the end cap turning it counter-clockwise until the end cap comes off. Set it aside

in a safe location.

DANGER

EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in a hazardous location could result in an explosion.

1. Grasp the end cap (front or rear).

2. Carefully align the end cap threads with the threads of the enclosure.

Important

When replacing the rear end cap, ensure wires connecting to the terminal plate do not get crimped or caught between the end cap threads and the enclosure.

3. Screw the end cap clockwise (eight full turns) until it is tightly sealed to the enclosure.

4. Replace the retaining clamp (if applicable).

Bolting Considerations

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.

If the flow computer installation requires assembly of a process flange, manifold, or flange adapters, follow these assembly guidelines to ensure a tight seal for optimal performance characteristics of the flow computer.

Only use bolts supplied with the flow computer or sold by Emerson as spare parts. Refer to the figures, below, for common flow computer assemblies with the bolt length required for proper flow computer installation.

Note

For all other manifolds, contact your local Emerson Sales office or Emerson Impact Partner.

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the markings on the head of the bolt and referencing Table 2. If bolt material is not shown in the table, contact your local Emerson representative for more information.

Use the following bolt installation procedure:

1. Carbon steel bolts do not require lubrication. Stainless steel bolts are factory-coated with

a lubricant to ease installation. Do not apply any additional lubricant when installing either type of bolt.

2. Finger-tighten the bolts.

3. Torque the bolts to the initial torque value using a crossing pattern. See Table 2 for initial

torque value.

4. Torque the bolts to the final torque value using the same crossing pattern. See Table 2 for

final torque value.

5. Verify that the flange bolts protrude through the sensor module before applying pressure.

Terminal Plate

The terminal plate includes the various terminal blocks (TB) for power and I/O connections. The appearance of the terminal plate varies depending upon whether you have the optional 6channel expansion I/O board installed with 3.81 mm pitch connectors; when it is installed there are eight or nine connections per terminal block instead of six 5.08 mm pitch connections. Compare your device to the pictures to see which terminal plate you have.
