PROCEDURES

Remove from Service

Remove Terminal Block

Do not remove the instrument cover in explosive atmospheres when the circuit is live.

Follow these steps:

•Follow all plant safety rules and procedures.

•Isolate and vent the process from the transmitter before removing the transmitter from service.

•Remove all electrical leads and disconnect conduit.

•Remove the transmitter from the process connection.

•The Rosemount 2051C transmitter is attached to the process connection by four bolts and two cap screws. Remove the bolts and separate the transmitter from the process connection. Leave the process connection in place and ready for re-installation.

•The Rosemount 2051T transmitter is attached to the process by a single hex nut process connection. Loosen the hex nut to separate the transmitter from the process. Do not wrench on neck of transmitter.

•Do not scratch, puncture, or depress the isolating diaphragms.

•Clean isolating diaphragms with a soft rag and a mild cleaning solution, and rinse with clear water.

•For the 2051C, whenever you remove the process flange or flange adapters, visually inspect the PTFE o-rings. Replace the o-rings if they show any signs of damage, such as nicks or cuts. Undamaged o-rings may be reused.

Electrical connections are located on the terminal block in the compartment labeled “FIELD TERMINALS.”

1.Remove the housing cover from the field terminal side.

2.Loosen the two small screws located on the assembly in the 9 o’clock and 3 o’clock positions.

3.Pull the entire terminal block out to remove it.

See “Safety Messages” on page 5-1 for complete warning information.
