Human-Machine Interface (HMI) Module

The flow computer includes an HMI module with an optional liquid crystal display (LCD) for local
operator access to the device. The LCD, if present, presents a series of menus that sequentially
display the current values of particular process variables. A configuration parameter in FBxConnect
determines whether you must log in first to view the menus. If required, you log in by selecting
alphanumeric characters by scrolling through a list until you select the correct character.
The HMI module includes four LEDs to provide status information. Units with the display include
four infrared (IR) buttons for operator interaction. To conserve power, the HMI module enters sleep
mode after a period of inactivity. The operator wakes up the device by holding a finger against the
front cover glass over the Hold to Wake button (the left-most button).
