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, shows 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. Sleep
mode disables FBxWifi 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.
