Maintenance
This section describes the major components, assembly, and disassembly of 846 current‐to‐pressure transducers.
WARNING
To avoid personal injury or property damage from the sudden release of pressure or air:
D Always wear protective clothing, gloves, and eyewear when performing any maintenance operations.
D 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.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
WARNING
The presence of Emerson Automation Solutions personnel and approval agency personnel may be required if you service
(other than normal, routine maintenance, such as calibration) or replace components on an 846 transducer that carries a
third‐party approval. When replacing components, use only components specified by the factory. Substitution with other
components may void the third‐party approval and result in personal injury or property damage.
Use only the procedures, and component replacement techniques specifically referenced in this manual. Unauthorized
procedures and improper techniques can cause poor quality repairs, impair the safety features of the device, and affect
product performance and the output signal used to control a process.
