how commission a transmitter evev plant is already running
Answer Posted / sam
1) Check whether the transmitter is in closed loop or not.
2)If it is in closed loop, then do the engineering login
from your server and force the current value.
3)Then come to field isolate the transmitter from the
process , open the vent make the transmitter entirely free
from process and see whether the transmitter is having the
zero error or not
4)If it is not having the zero error then make flush out the
impulse lines and take the transmitter in line
5)If it is having the zero error then do the zero
calibrstion from ur HART communicator by selecting online mode.
6)Observe the transmitter for 5 minutes then remove the
force and put the transmitter in closed loop.
