C. Power supply
Procedure
1. Connect the sensor.
See the wiring diagram located on the inside of the housing cover.
2. Connect the bench power supply to the power terminals ("+" or "-").
3. Connect a Field Communicator to the loop across a loop resistor or at
the power/signal terminals on the transmitter.
The following message will appear if the communicator has a previous
version of the device descriptors (DDs):
NOTICE: Upgrade the communicator software to access new XMTR functions.
Continue with old description?
Note
If this notice does not appear, the latest DD is installed.
If the latest version is not available, the communicator will communicate
properly, but when the transmitter is configured some new capabilities may
not be visible.
To prevent this from happening, upgrade to the latest DD or answer NO to
the question and default to the generic transmitter functionality.
