Maintenance & Troubleshooting
NOTE
The Sensor Module Checkout procedure does not
completely test the sensor module. If electronics assembly
replacement does not correct the abnormal condition and no
other problems are obvious, replace the sensor module.
NOTE
Before removing the transmitter from service:
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 conduit.
•
Residual process fluid may remain after disassembly of
process flanges. If this fluid is potentially contaminated, take
appropriate safety measures.
NOTE
Numbers in parentheses refer to item numbers in Figure 5-1.
NOTE
2151N transmitters contain electronic circuit boards which
may be static sensitive. Therefore, observe proper ESD
precautions/techniques whenever the electronics assemblies
are handled and/or uncovered.
NOTE
Special testing and part replacement are required for
reassembly. Read the Process Flange Reassembly
procedure (see pg. 59) before attempting disassembly.
