Operation and Maintenance
4.6.4 LCD display
Transmitters ordered with the LCD display will be shipped with the display installed. Installing
the display on an existing 3051S MultiVariable Transmitter requires the LCD display kit (part
number 03151-9193-0001 for aluminum housing and 03151-9193-0004 for stainless steel
housing).
Use the following procedure and Figure 4-13 to install the LCD display:
1. If the transmitter is installed in a loop, then secure the loop and disconnect power.
2. Remove the transmitter cover on the feature board side (opposite the field terminals
side). Do not remove the instrument covers in explosive environments when the circuit
is live.
3. Engage the four-pin connector into the feature board and snap the LCD display into
place.
4. Install the display cover and tighten to insure metal to metal contact in order to meet
flameproof/explosion-proof requirements.
