General Features

HMI (Human-Machine Interface)

Each BE1-11d has a front-panel display and 12 LED indicators: Power

Supply Status, Relay Trouble Alarm, Minor Alarm, Major Alarm, Trip, and 

Indicator 1 through 7 (programmable in BESTlogicPlus). The backlit, liquid

crystal display (LCD) allows the BE1-11d to replace local indication and

control functions such as panel metering, alarm annunciation, and control 

switches. Four scrolling pushbuttons enable navigation through the LCD

menu tree. Parameters are changed using the Edit pushbutton. Targets,

alarms, and other registers are cleared with the Reset pushbutton.

In Edit mode, the scrolling pushbuttons provide data entry selections.

Edit mode is indicated by an LED on the Edit pushbutton.

Select Control Switch and Operate Control Switch pushbuttons provide a

means to control the logic switches.

The LCD has automatic priority logic to govern which metering values are

displayed on the screen so that when an operator approaches, the metering

data of most interest is automatically displayed without having to navigate

the menu structure. Scrollable metering parameters are selected on the

General Settings, Front Panel HMI settings screen in BESTCOMSPlus.
