10.13 Diagnosing wiring problems
Use the procedures in this section to check the transmitter installation for wiring problems.
10.13.1 Checking the power supply wiring
To check the power supply wiring:
1. Verify that the correct external fuse is used. An incorrect fuse can limit current to the
transmitter and keep it from initializing.
2. Power down the transmitter.
3. If the transmitter is in a hazardous area, wait five minutes.
4. Ensure that the power supply wires are connected to the correct terminals. Refer to
Appendix B for diagrams.
5. Verify that the power supply wires are making good contact, and are not clamped to the wire
insulation.
6. (Model 1700/2700 transmitters only) Inspect the voltage label on the inside of the field-wiring
compartment. Verify that the voltage supplied to the transmitter matches the voltage specified
on the label.
7. Use a voltmeter to test the voltage at the transmitter’s power supply terminals. Verify that it is
within the specified limits. For DC power, you may need to size the cable. Refer to
Appendix B for diagrams, and see your transmitter installation manual for power supply
requirements.
10.13.2 Checking the sensor-to-transmitter wiring
To check the sensor-to-transmitter wiring, verify that:
• The transmitter is connected to the sensor according to the wiring information provided in
your transmitter installation manual. Refer to Appendix B for diagrams.
• The wires are making good contact with the terminals.
If the wires are incorrectly connected:
1. Power down the transmitter.
2. If the transmitter is in a hazardous area, wait five minutes.
3. Correct the wiring.
4. Restore power to the transmitter.
WARNING
Removing the wiring compartment covers in
explosive atmospheres while the power is on can
subject the transmitter to environmental conditions
that can cause an explosion.
Before removing the wiring compartment cover in
explosive atmospheres, be sure to shut off the power and
wait five minutes.
