Q
Dear All,
I could like to have the advice from all members of control.com on our plant issue of Rosemount 2051.
The problem is: transmitter still showing the PV value on LCD, but mA output measure from TEST, NEGATIVE terminal showing only 2.5mA. Hart communicator showing "Can not found device." When power 24VDC supply take OFF (purpose to reset transmitter) and checking the power supply is 24.3VDC, then connect power again transmitter not showing PV value, completely black. The electronic board (behind the LCD board) was dead. We change other electronic board, transmitter is normal showing PV on LCD and also mA correspondent.
We found two transmitter same above problem.
Do you have any advice of what is the cause could be highly appreciate.
thanks
