If you're experiencing issues with the position switch circuit of your Emerson Transmitter, first, make sure the circuit is correctly connected and the terminal marked (R) on the field circuit printed wiring board goes back to the negative terminal of the power supply. Additionally, verify that the power supply voltage is between 20 and 30 volts DC.
How to troubleshoot potentiometer problems in Emerson Fisher 4210 Transmitter?
If the potentiometer is causing issues with your Emerson Transmitter, you can try performing the potentiometer alignment. Alternatively, you might need to replace the pot/bushing assembly. You can also try performing the potentiometer alignment procedures and then repeating step 8. As a last resort, consider replacing the transmitter printed wiring board or sending the transmitter to the factory for repair.
What to do if voltage is not present at test points in Emerson Fisher 4210?
If there's no voltage at the test points of your Emerson Transmitter, either replace the printed wiring board or return the instrument to the factory for repair.
How to fix an Emerson Fisher 4210 that is not operating properly?
If your Emerson Transmitter isn't working right, maintenance can be done by sending the whole thing to the factory for repair, swapping out the printed wiring board(s), or replacing the pot/bushing assembly.
How to troubleshoot an Emerson Fisher 4210 not functioning properly?
To troubleshoot an Emerson Transmitter that is not functioning properly, start by verifying that the instrument is receiving power and that the receiving devices are operating correctly. Ensure that the power supply voltage is between 20 and 30 volts DC. Check the position switch circuit connection, making sure the terminal marked (R) on the field circuit printed wiring board returns to the negative terminal of the supply. You can also troubleshoot the transmitter circuit by measuring the voltages V3 and V4. If V3 and V4 are correct, perform the high and low position switch calibration procedures.
What to do if the potentiometer is the source of trouble in Emerson Fisher 4210?
If the potentiometer may be the source of trouble in your Emerson Transmitter, check the voltage between TP3 (+) and TP4 (?) as you vary the potentiometer's position. For Type 4212 and 4222 transmitters, check the voltage between TP5 and TP6 as you vary the potentiometer's position. If the voltage doesn't change with position, perform the potentiometer alignment. If the problem continues, replace the pot/bushing assembly.
What to do if Emerson Fisher 4210 Transmitter output is constant or non-linear?
If the potentiometer wiper voltage checks good, but the Emerson Transmitter output is constant or non-linear, perform the potentiometer alignment procedures and then repeat step 8 above. If the potentiometer voltage is present but the transmitter output current does not change linearly as the position of the potentiometer changes, replace the transmitter printed wiring board, or return the transmitter to the factory for repair.
What to do if the position switches cannot be set on Emerson Fisher 4210 Transmitter?
If the position switches of your Emerson Transmitter cannot be set, replace the field circuit printed wiring board or return the instrument to the factory for repair.
