6.1 Wall Mounting Interface
The Wall Operator Interface is a display unit with keypad for user setup, calibration and routine
interaction with the sensor. It is constructed in a cast aluminum housing rated for Nema 12 (IP 55).
The display is a two-line 20 character vacuum fluorescent display. It may be mounted up to 100 feet
from the sensor and obtains both power and communications from the sensor.
6.2 Initial Power-Up
After installation and cable connection is complete, turn the power on at the breaker. The display on the
operator interface will illuminate indicating power-up and the sensor will emit a flashing green light.
6.3 Keypad
The front of the Operator Interface contains eight keys that allow the user to setup, calibrate and check
internal diagnostics of the MCT.
