Rosemount 3051 screen not working

Rosemount 3051 screen not working

Rosemount 3051 screen not working

(OP)
Hi

After powering up a brand-new 3051(flange mounted wetleg) I noticed the screen does not show any indication(its blank). I can communicate with the instrument with Hart 375 communicator.

2 days earlier I unscrewed the screen and pulled it out to see if I could change the rotation of its mounting as the instrument needs to lie horizontally. I decided to not change anything and put the screen back together. Naturally I thought I must of put it back together wrong when the screen did not come on, so I checked and all seemed ok. I lifted up the 2nd block that held the wiring coming from the back of the transmitter and also had 2 copper prongs than looked to seat into two positions of the block above it. Now thinking that I shouldn't have touched it...... arrrrgh. young and keen.....


I did not touch the 2 switches that are under the front cover.
The 2nd identical transmitter I got did not have any problems with the screen.

Any ideas?


Thanks for any help

Dave

RE: Rosemount 3051 screen not working

The 3051 manual says the display can be rotated, like one would expect. So it isn't positioned by a factory watchmaker. The manual only mentions aligning the electrical connector pins.

If I had two identical transmitters I'd put the good display in the questionable location and confirm that the dark display is toast, then arrange for a warranty replacement.

Bit of a late reply sorry.

I sorted the problem. the long cooper pins were misaligned on the inside end of the connection block so i couldnt see anything wrong when looking from the side.

Rookie mistake..... though atleast the scrren wasnt buggered hahaha

Not a rookie mistake, I still make those after 50 years LOL
