EST3 Trouble address

I’m not exactly sure how to ask this, but here goes… lol

I have a trouble on a panel, it says open/fault 03030681…

I know by the code it’s panel-3, card-3… what is the 0681?

“0681” appears to be a Trouble Pseudo Point on the EST 3 system. According to the manual, it indicates a “Line Opened or Shorted” condition on “Data Card 2”. It also lists the 3-DSDC, 3-SSDC1, and 3-SDDC1 cards as possible sources of the trouble condition.

Here’s a link to the manual, with the local trouble pseudo points listed on page 8.30: <LINK_TEXT text=“ … manual.pdf”></LINK_TEXT>
