Termination of 4-Wire Instrument at Redundant Analog Input Card Terminal Block.

Dear All,

Greetings of the Days ! ! !

I faces one issue while configuring the 4-wire instrument at Redundant Analog Input Card Terminal Block.

As per DeltaV Books Online we rotate the jumper of redundant terminal block as 4 wire instrument and then channel 1 to 4 can be used as 4 wire instrument.

However when i am connecting the 4-wire instrument at Channel 1 & 2 then i get the Sensor Bad error in Diagnostics however when i connect at other all channel 3 to 8 then it shows the value.

and card and terminal block both are working good in 2 wire configuration.
