Remove the transmitter
from Service
Once a transmitter is determined to be inoperable, remove it from service.
Be aware of the following:
•
Isolate and vent the process from the transmitter before removing the
transmitter from service.
•
Remove all electrical leads and conduit.
•
Detach the process flange by removing the four flange bolts and the
two alignment screws that secure it.
•
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.
•
Whenever you remove the process flange or flange adapters, visually
inspect the Teflon O-rings. Replace the O-rings if they show any signs
of damage, such as nicks or cuts. If they are undamaged, you may
reuse them.

labeled “FIELD TERMINALS.” Remove the housing cover (see Figure 5-1).
Loosen the two small screws located at the 9 o'clock and 4 o'clock positions,
and pull the entire terminal block out to remove it.
