Function, Technical data, Specification text, Order code, Related products
The BE-LCD control panel is used to display and control the most critical aerodynamic and safety-related functions of a fume cupboard or a room. Users
obtain information regarding the condition of the fume cupboard or room and can select among various operating modes. The individual display elements
and controls are as follows:
Three-colour status display
Warning display
40-character display
Alarm sounder
8 function button fields: 1 acoustic alarm acknowledgement, 3 operating mode buttons, 2 buttons for the automatic sash device, 1 button for the fume
cupboard lighting, 1 button for manual control
Service socket
The range of functions of the control panel can be adapted to project-specific requirements using the EasyConnect configuration software. The range of
functions may vary for different fume cupboards or rooms.
The function button fields are used for display and for operation. The available functions are highlighted in blue.
A required function can be selected by pressing the corresponding button.
Selecting an operating mode
Automatic sash device
Fume cupboard lighting on/off
The 40-character display shows system messages or, if enabled, actual values.

Control input signal for an individually usable relay changeover contact, e.g. for lighting
Control input signal for sun protection/blinds (to be provided by others)
Increased volume flow and manual mode can be set for a limited period
Depending on the control strategy and configuration, the control panel monitors and signals for example the total volume flow rates or pressure conditions
for a room that is equipped with up to 24 EASYLAB controllers. Relevant deviations are indicated on the three-colour status display. As an option, acoustic
alarms can be configured. Controller faults are signalled to the room control panel as an configurable consolidated alarm. The necessary data is
exchanged between the controllers via the EASYLAB communication cable.
