Transmitter model NO 2051 pressure transmitter
As per manual we connected pit with 24 dc and & HART 475 COMM. After power up showing no field bus communication found. Anyway connect to segment then HART connecting segment showing LAS. Also when it’s going to advance there is no instrument tags appear

Please give us instruction for this issue.

Mahmoud,

What is your 2051 transmitter detailed ordering information?
example : 2051C D 2 A 2 2 A 1 A B4 M5

have you try troubleshooting procedures suggested by Rosemount 2051 Reference Manual 00809-0100-4101
(http://www2.emersonprocess.com/siteadmincenter/PM Rosemount Documents/00809-0100-4101.pdf)

page 5-2:

Transmitter Not Communicating with HART Communicator:
- Verify the output is between 4 and 20 mA or saturation levels

- Verify terminal voltage is 10.5 to 42.4 Vdc

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

- Check loop resistance, 250 ? minimum (PS voltage -transmitter voltage/loop current)

- Have HART Communicator poll for all addresses

If so, what is the result?
