Check that the cables are connected.
Check that PWR+ is connected to + and PWR- is connected to - on the power
supply.
Make sure the Rosemount 5300 Series Transmitter is supplied with 8-30 Vdc
(max. rating).
Try alternating MA/MB if you are unsure of the polarity.
If an RS-485 converter is used, make sure it is properly installed and configured.
The last Rosemount 5300 Series Transmitter may need a terminating 120-
resistor connected between MA and MB.
