Cover

For transmitters ordered with the LCD meter, the meter is shipped installed. Installing the meter on an existing Rosemount 3051N transmitter requires a small instrument screwdriver and the meter kit (when the kit is made available by Rosemount Nuclear Instruments, Inc.).

To maintain the Rosemount 3051N qualification status, any piece parts for the Rosemount 3051N (if available) must be supplied by RNII.

The meter kit includes:

one LCD meter assembly

one extended cover with O-ring installed

two nylon standoffs

two captive screws

one ten-pin interconnection header

Use the following procedure and Figure 6-1to install the LCD meter.

1.IF the transmitter is installed in a loop, THEN secure the loop and disconnect power.

2. Remove the transmitter cover opposite the field terminal side. Do not remove the instrument covers in explosive environments when the circuit is alive.

3.Remove the failure mode and alarm jumpers from the electronics module and insert them in their new positions above and below the meter readout on the meter assembly.

See “Safety Messages” in Section 6 for warning information.
