Table 5-2. Troubleshooting.
Symptom
Potential Source
Corrective Action
High Output
Primary Element
Check for restrictions at primary element, improper installation or poor condition. Note any
changes in process fluid properties that may affect output.
Impulse Piping
Check for leaks or blockage.
Ensure blocking locking valves are fully open.
Check for entrapped gas in liquid lines, or liquid in dry lines.
Ensure that density of fluid in impulse line is unchanged.
Check for sediment in transmitter process flanges.
Transmitter Electronics Make sure that post connectors and the sensor connections are clean. If the electronics are still
suspect, substitute new electronics.
Transmitter Electronics
Failure
Determine faulty circuit board by trying spare boards. Replace faulty circuit board.
Sensing Module
NOTE: See Sensing Module Checkout section. The sensing element is not field repairable and
must be replaced if found to be defective. See “Disassembly Procedure” for instructions on
disassembly. Check for obvious defects, such as a punctured isolating diaphragm or fill fluid
loss, and contact Rosemount Nuclear Instruments, Inc. at 952-949-5210.
Power Supply
Check the power supply output voltage at the transmitter.
Low Output or
No Output
Primary Element
Check for restrictions at primary element, improper installation or poor condition.
Note any changes in process fluid properties that may affect output.
Loop Wiring
Check for adequate voltage to the transmitter.
Check the milliamp rating of the power supply against the total current being drawn for all
transmitters being powered.
Check for shorts and multiple grounds.
Check for proper polarity at the signal terminal.
Check loop impedance.
Check wire insulation to detect possible shorts to ground.
Impulse Piping
Ensure that the pressure connection is correct.
Check for leaks or blockage.
Check for entrapped gas in liquid lines.
Check for sediment in the transmitter process flange.
Ensure that blocking valves are fully open and that bypass valves are tightly closed.
Ensure that density of the fluid in the impulse piping is unchanged.
Transmitter Electronics
Connections
Ensure that calibration adjustments are in allowable range.
Check for shorts in sensor leads.
Make sure post connectors are clean, and check the sensor connections.
If the electronics are still suspect, substitute new electronics.
Test Diode Failure
Replace electronics housing.
Transmitter Electronics
Failure
Determine faulty circuit board by trying spare boards. Replace faulty circuit board.
Sensing Module
NOTE: See Sensing Module Checkout section. The sensing element is not field repairable and
must be replaced if found to be defective. See “Disassembly Procedure” for instructions on
disassembly. Check for obvious defects, such as a punctured isolating diaphragm or fill fluid
loss, and contact Rosemount Nuclear Instruments, Inc. at 952-949-5210.
Power Supply
Check the power supply output voltage at the transmitter.

Do not use over 100 volts to check the loop, or damage to the
transmitter electronics may result.
