Installation
To install the LCD display:
1. If the transmitter is installed in a loop, set the loop to manual (HART) / out-of-service
(F
OUNDATION fieldbus) mode and disconnect the power.
2. Remove the housing cover from the electronics side of the transmitter. Do not remove
the transmitter covers in explosive atmospheres with a live circuit.
3. Ensure that the transmitter write protect switch is set to the Off position. If transmitter
security is On, the transmitter cannot be configured to recognize the LCD display. If
security On is desired, configure the transmitter for the LCD display, and then install the
meter.
4. Insert the interconnection header in the 10-pin socket on the face of the electronics
module. Insert the pins into the electronics LCD display interface.
5. The meter can be rotated in 90-degree increments for easy viewing. Position one of the
four 10-pin sockets on the back of the meter to accept the interconnection header.
6. Attach the LCD display assembly to the interconnection pins, then thread and tighten
the LCD display screws into the holes on the electronics module.
7. Attach the extended cover; tighten at least one-third turn after the O-ring contacts the
transmitter housing. Both transmitter covers must be fully engaged to meet explosion
proof requirements.
8. Apply power and set the loop to automatic (HART) / in-service (F
OUNDATION fieldbus)
mode.
Once the LCD display is installed, configure the transmitter to recognize the meter option. Refer
to “LCD display options” on page 94 (HART) or “LCD display transducer block” on page 152
(F
OUNDATION fieldbus).
Note
Observe the following LCD display temperature limits:
Operating:–4 to 185 °F (–20 to 85 °C)
Storage:–50 to 185 °F (–45 to 85 °C)
