Use of components not supplied by Emerson may void your warranty, might
adversely affect the performance of the product, and could result in personal
injury and property damage.
Installation
WARNING
Avoid personal injury or property damage from the sudden release of process
pressure or bursting of parts. Before mounting the product:
- Do not install any system component where service conditions could exceed the limits given in this manual or the limits on the appropriate nameplates. Use pressure‐relieving devices as required by the government or accepted industry codes and good engineering practices.
- Always wear protective gloves, clothing, and eyewear when performing any installation operations.
- Do not remove the actuator from the valve while the valve is still pressurized.
- Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.
- Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve.
- ent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not applying force to the valve stem; this will allow for the safe removal of the stem connector.
- Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
- The instrument is capable of supplying full supply pressure to connected equipment. To avoid personal injury and equipment damage, caused by the sudden release of process pressure or bursting of parts, make sure the supply pressure never exceeds the maximum safe working pressure of any connected equipment.
- Severe personal injury or property damage may occur from an uncontrolled process if the instrument air supply is not clean, dry, and oil‐free, or noncorrosive gas. While the use and regular maintenance of a filter that removes particles larger than 40 microns will suffice in most applications, check with an Emerson field office and Industry Instrument air quality standards for use with corrosive gas or if you are unsure about the proper amount or method of air filtration or filter maintenance
- For corrosive media, make sure the tubing and instrument components that contact the corrosive media are of suitable corrosion-resistant material. The use of unsuitable materials might result in personal injury or property damage due to the uncontrolled release of the corrosive media.
- If natural gas or other flammable or hazardous gas is to be used as the supply pressure medium and preventive measures are not taken, personal injury and property damage could result from fire or explosion of accumulated gas or from contact with hazardous gas. Preventive measures may include, but are not limited to: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation, and the removal of any ignition sources.
- To avoid personal injury or property damage resulting from the sudden release of process pressure, use a high‐pressure regulator system when operating the controller or transmitter from a high‐pressure source. The instrument or instrument/actuator assembly does not form a gas‐tight seal, and when the assembly is in an enclosed area, a remote vent line, adequate ventilation, and necessary safety measures should be used. Vent line piping should comply with local and regional codes and should be as short as possible with the adequate inside diameter and few bends to reduce case pressure buildup. However, a remote vent pipe alone cannot be relied upon to remove all hazardous gas, and leaks may still occur
- Personal injury or property damage can result from the discharge of static electricity when flammable or hazardous gases are present. Connect a 14 AWG (2.08 mm ) ground strap between the instrument and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements. 2
- Personal injury or property damage caused by fire or explosion may occur if electrical connections are attempted in an area that contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of covers before proceeding.
- Personal injury or property damage, caused by fire or explosion from the leakage of flammable or hazardous gas, can result if a suitable conduit seal is not installed. For explosion‐proof applications, install the seal no more than 457 mm (18 inches) from the instrument when required by the nameplate. For ATEX applications use the proper cable gland certified to the required category. Equipment must be installed per local and national electric codes.
- Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
If installing into an existing application, also refer to the WARNING in the Maintenance section.
Special Instructions for Safe Use and Installations in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may
have unique installation requirements and/or conditions of safe use. Special
instructions are listed by agency/approval. To get these instructions, contact
Emerson’s sales office. Read and understand these special conditions of use
before installing.
WARNING
Failure to follow conditions of safe use could result in personal injury or
property damage from fire or explosion, or area re‐classification.
Operation
With instruments, switches, and other accessories that are controlling valves
or other final control elements, it is possible to lose control of the final
control element when you adjust or calibrate the instrument. If it is
necessary to take the instrument out of service for calibration or other
adjustments, observe the following warning before proceeding.
WARNING
Avoid personal injury or equipment damage from uncontrolled processes. Provide
some temporary means of control for the process before taking the instrument
out of service.
Maintenance
WARNING
Avoid personal injury or property damage from the sudden release of process
pressure or bursting of parts. Before performing any maintenance operations on
an actuator‐mounted instrument or accessory:
- Always wear protective gloves, clothing, and eyewear.
- Provide some temporary measure of control to the process before taking the instrument out of service.
- Provide a means of containing the process fluid before removing any measurement devices from the process.
- Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.
- Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve.
- Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not applying force to the valve stem; this will allow for the safe removal of the stem connector.
- Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
- Check with your process or safety engineer for any additional measures that must be taken to protect against process media. When using natural gas as the supply medium, or for explosion-proof applications, the following warnings also apply:
- Remove electrical power before removing any housing cover or cap. Personal injury or property damage from fire or explosion may result if power is not disconnected before removing the cover or cap.
- Remove electrical power before disconnecting any of the pneumatic connections.
- When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any ignition sources.
- Ensure that all housing caps and covers are correctly installed before putting this unit back into service. Failure to do so could result in personal injury or property damage from fire or explosion.
Instruments Mounted on Tank or Cage
WARNING
For instruments mounted on a tank or displacer cage, release trapped pressure
from the tank and lower the liquid level to a point below the connection. This
precaution is necessary to avoid personal injury from contact with the process
fluid.
Instruments With a Hollow Displacer or Float
WARNING
For instruments with a hollow liquid level displacer, the displacer might
retain process fluid or pressure. Personal injury and property might result
from the sudden release of this pressure or fluid. Contact with hazardous
fluid, fire, or explosion can be caused by puncturing, heating, or repairing a
displacer that is retaining process pressure or fluid. This danger may not be
readily apparent when disassembling the sensor or removing the displacer. A
displacer that has been penetrated by process pressure or fluid might
contain:
- pressure as a result of being in a pressurized vessel
- liquid that becomes pressurized due to a change in temperature
- liquid that is flammable, hazardous, or corrosive.
Handle the displacer with care. Consider the characteristics of the specific process liquid in use. Before removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.
