please let me know what is purpose of Emerson Rosemount 3051 Transmitter front display Jumper for Alarm (high, low). also security Jumper (on, off).

 

Irfan,

What does the manufacturer's Instruction/Application Manual say the jumpers are to be used for?

 

hi

as per manual instruction jumper for alarm low and high. if transmitter goes to fail mode then output will be high or low as per setting.

for example in temp. mostly i have seen they put high alarm jumper.

and security off means you cannot overwrite the application.
