Troubleshooting

Table 6-1. Rosemount 2051G Troubleshooting for 4–20 mA Output

Symptom

Corrective actions

Transmitter milliamp reading is

zero

Verify terminal voltage is 10.5 to 42.4 Vdc at signal terminals

Check power wires for reversed polarity

Check that power wires are connected to signal terminals

Check for open diode across test terminal

Transmitter not communicating

with Field Communicator

Verify terminal voltage is 10.5 to 42.4 Vdc

Check loop resistance, 250

minimum (PS voltage -transmitter voltage/loop current)

Check that power wires are connected to signal terminals and not test terminals

Verify clean DC Power to transmitter (Max AC noise 0.2 volts peak to peak)

Verify the output is between 4 and 20 mA or saturation levels

Have Field Communicator poll for all addresses

Transmitter milliamps reading is

low or high

Verify applied pressure

Verify 4 and 20 mA range points

Verify output is not in alarm condition

Perform analog trim

Check that power wires are connected to the correct signal terminals (positive to positive,

negative to negative) and not the test terminal

Transmitter will not respond to

changes in applied pressure

Check impulse piping or manifold for blockage

Verify applied pressure is between the 4 and 20 mA points

Verify the output is not in alarm condition

Verify transmitter is not in loop test mode

Verify transmitter is not in multidrop mode

Check test equipment

Digital pressure variable reading

is low or high

Check impulse piping for blockage or low fill in wet leg

Verify transmitter is calibrated properly

Check test equipment (verify accuracy)

Verify pressure calculations for application

Digital pressure variable reading

is erratic

Check application for faulty equipment in pressure line

Verify transmitter is not reacting directly to equipment turning on/off

Verify damping is set properly for application

Milliamps reading is erratic

Verify power source to transmitter has adequate voltage and current

Check for external electrical interference

Verify transmitter is properly grounded

Verify shield for twisted pair is only grounded at one end
