October 2016
Note
Do not rotate the housing more than 180° without first performing a disassembly
procedure. See Section 4 of the Rosemount 3051SMV
information. Over-rotation may sever the electrical connection between the sensor module
and the feature board electronics.

3.0 Set the switches

The transmitter's default configuration sets the alarm condition to high (HI) and
the security to off.
1. If the transmitter is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminals side. Do not remove
the housing cover in explosive environments.
3. Slide the security and alarm switches into the preferred position by using a
small screwdriver.
4. Reinstall the housing cover so that metal contacts metal to meet
explosion-proof requirements.

4.0 Connect wiring and power up

Note
Do not connect the power across the test terminals. Power could damage the test diode in
the test connection. Twisted pairs yield best results. Use 24 AWG to 14 AWG wire and do
not exceed 5,000 feet (1500 meters).
Use the following steps to wire the transmitter:
1. Remove the cover on the field terminals side of the housing.
2. Connect the positive lead to the "PWR/COMM +" terminal, and the negative
lead to the "PWR/COMM –" terminal.
3. If the optional process temperature input is not installed, plug and seal the
unused conduit connection. If the optional process temperature input is being
utilized, see
