8 Introduction
1.8 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
displays the current values of particular process variables. A configuration parameter in FBxConnect
determines whether you must first log in 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. Sleep mode
disables Wi-Fi communication. In FBxConnect, you can configure the number of minutes of
inactivity triggering sleep mode through the LCD Sleep Time parameter. Setting this parameter to
0 disables sleep mode which keeps the HMI module on but uses significantly more power.

Note
If your flow computer does not include the LCD option (shown in Figure 1-4), you still have the
status LEDs and a single IR button for waking up the device (shown in Figure 1-5).
