Answer / k.sreenivasan

Go to the field and check the local indication in the
transmitter.(normally it is in either engg. units or as
percentage)
If it is zero ,then the problem is in the sensor or
terminal connection, because most of the current generation
transmitters are highly accurate and have longer stability
periods.
Suppose local reading is ok,then check the DCS analog input
card for any fault condition and clear it.Normally this
situation is rare.

Check the Sensor properly. if it is ok, then
1)check continuity between the sensor cables
2)tight the cables properly
3)check the transmitter supply (24vdc)
if it is not ok, then check the DCS analog i/p cord.

1. Check the wiring at all terminal blocks at field, at
control panel and at PLC for any loose connection.
2. Check the Transmitter supply.
3. Measure the output from Transmitter.
4. Check cable continuity.
5. Finally check the configuration of TAG in the DCS (may
be someone deleated accidently).
