Symptom

Corrective Actions

 

 

Milliamp Reading Is Zero

Check if power polarity is reversed.

 

• Verify voltage across terminals (should be 10 to 55 V dc).

 

• Check for bad diode in terminal block.

 

 

 

Transmitter Not Communicating with

Check power supply voltage at transmitter (minimum 10.5 V).

HART Communicator

• Verify calibration settings (4 and 20 mA points)

 

 

• Check load resistance (250 Ω minimum).

 

• Check if unit is addressed properly.

 

 

 

Milliamp Reading Is Low or High

Check pressure variable reading for saturation.

 

• Check if output in alarm condition.

 

• Verify 4 and 20 mA range points.

 

• Perform 4–20 mA output trim.

 

 

 

No Response to Changes in

Check test equipment.

Applied Pressure

• Check impulse piping for blockage.

 

 

• Check disabled span adjustment.

 

• Check if output in alarm condition.

 

 

 

Pressure Variable Reading Is

Check impulse piping for blockage.

Low or High

Check test equipment.

 

 

• Perform full sensor trim.

 

 

 

Pressure Variable Reading Is Erratic

Check impulse piping for blockage.

 

Check damping.

 

• Check for EMF interference.
