Symbols used in this manual
This operatin manual describes the EASYLAB
BE-LCD-01 control panel for fume cupboard control
and room control.
To ensure complete functionin of the control panel
it is essential to read this operatin and installation
manual before startin any work, and to comply
with it. The manual must be iven to the facilities
mana er when handin over the system. The
facilities mana er must include the manual with
the system documentation.
The manufacturer does not accept any liability
for any malfunction or dama e resultin from
non-compliance with these instructions or non-
compliance with relevant statutory re ulations.
Other applicable documentation
In addition to this manual, the followin documents
apply:
• Control Systems catalo ue

– EASYLAB TCU3 controller
– EASYLAB TAM adapter module
• EASYLAB Confi uration Software Operatin

• Project-specific wirin documents
1 General information

General information regarding safety
Only skilled qualified personnel are allowed to
perform the described work on the control panel.
Only skilled qualified electricians are allowed to
work on the electrical system.
For all work performed on EASYLAB components,
the followin re ulations and uidelines must be
complied with. This applies in particular to the
followin German country specific re ulations or
as appropriate in the country where the installation
is takin place:
• Equipment and Product Safety Laws (GPSG)
• Industrial Health and Safety Re ulations
(BetrSichV)
• Accident Prevention Re ulations (BGV A1,
BGV A3)
General safety measures
• Large temperature differences
Condensation can dama e the electronics
beyond repair. If the control panel has been
kept in an unheated area, wait at least two
hours before switchin on the supply volta e
for commissionin .
• Electrostatic charge
Electrostatic char e can dama e the electronics.
To avoid this, first touch an equipotentially
bonded metal surface, e. . a water pipe, for
electrical earthin before you remove the control
panel from its protective wrappin .
• Fixing the base plate and the adapter
Ti hten the screws only hand-ti ht in order to not
dama e the base plate or the adapter.
• Foreign matter and liquids
If liquid ets inside the control panel, let
the control panel completely dry before
commissionin . Remove forei n matter, if any.
If the device emits a smell or smoke, have it
checked by the manufacturer.
4 BE-LCD-01 Operatin and Installation Manual / Leaflet no. M375EV8 (01/2015)
2 Safety and correct use
Correct use
The BE-LCD-01 control panel is an EASYLAB
component intended for the display of values and
for performin various functions. If the control panel
is connected to a fume cupboard controller, the
function display complies with EN 14175; operatin
functions and special functions can be set by
the user. If a room is equipped with EASYLAB
controllers, the control panel is intended for
monitorin and for operatin mode default settin .
• Connect the control panel to an EASYLAB TCU3
used for fume cupboard control (equipment
function FH-xxx).
• Connect the control panel to a EASYLAB TCU3
controller used for extract air control (equipment
function RE), supply air control (equipment
function RS), or room pressure control
(equipment function PC).
• Connect the control panel to an EASYLAB TAM
adapter module with active room mana ement
function (RMF).
• Surface mount the control panel onto the side
frame of the fume cupboard.
• As an alternative, mount the control panel to a
wall, with our without junction box.
• Observe the technical data for the control panel.
Incorrect use
Do not use the control panel outdoors, in wet areas,
or in potentially explosive atmospheres.
Residual ris s
A failure of the supply volta e is indicated on the
control panel only if the EASYLAB controller is
equipped with the EM-TRF-USV expansion module
and the battery pack has been connected and fully
char ed.

Overriding operating mode defaults set
by the central BMS
Operatin mode default settin s from the central
BMS or from the room control panel can be
overridden on the control panel for the fume
cupboard controller.
Temporary override
A centrally set operatin mode can be temporarily
overridden at any time usin the operatin mode
button on the control panel. The operatin mode
selected on the control panel remains active until
the central BMS sets another operatin mode. If the
central BMS sets a different default operatin
mode, it overrides the locally activated operatin
mode.
Manual control for permanent override
A centrally set operatin mode can be
permanently overridden on the control
panel. To do so, first activate manual
control by pressin the correspondin
button to prevent further overrides from
the central BMS. Then set any other operatin
mode on the control panel.
This operatin mode default settin can be
terminated by pressin the manual control button
a ain. The fume cupboard controller then resumes
the previous operatin mode from the central BMS.
Manual operation can be set for a limited period of
time. The manual mode will then automatically be
deactivated after the set delay and the previous
operatin mode will be resumed.
No override option
The central BMS can suppress overrides from the
control panel temporarily or permanently. In this
case, manual control cannot be used, and the
control panel shows only the centrally set operatin
mode. If a user attempts to chan e the operatin
mode on the control panel, the active operatin
mode will blink briefly.

These buttons are used to control the automatic
sash device.
The buttons can be used only if an automatic sash
device has been confi ured.

Overriding operating mode defaults set
by the central BMS
Operatin mode default settin s from the central
BMS can be overridden on the control panel for the
room.
Overriding the room operating mode
temporarily
A centrally set room operatin mode can be
temporarily overridden at any time usin the
operatin mode button on the control panel. The
operatin mode selected on the room control panel
remains active unless the central BMS sets another
operatin mode. If the central BMS sets a different
default operatin mode, that operatin mode
overrides the locally activated operatin mode.
The operatin mode for all room controllers is
always the operatin mode that has been set last,
either by the central BMS or on the room control
panel.
Overriding the room operating mode
permanently using manual control
A centrally set room operatin mode
can be permanently overridden on the
room control panel. To do so, activate
manual control by pressin the
correspondin button. This prevents
further overrides by the central BMS. You can then
set any other operatin mode usin the control

To resume the previous operatin mode from the
central BMS, press the manual mode button a ain.
Manual operation can be set for a limited period.
The manual mode will then automatically be
deactivated after the set delay, and the previous
operatin mode will be resumed.
No override option for the room operating
mode
The central BMS can be confi ured to block
the override function on the room control panel
temporarily or permanently. In this case, manual
control cannot be used, and the control panel
shows only the centrally set operatin mode. If a
user attempts to chan e the operatin mode on
the control panel, the active operatin mode will
blink briefly.
Lighting
Use this button to switch the room li htin on or off.
This function is only available if the
room mana ement function has been
confi ured accordin ly.
This button can also be used for other
functions instead of or in addition to
switchin the li htin on/off, e. . for switchin
certain devices on/off.
Sun protection (e.g. blinds)
Use these buttons to operate the sun protection,
e. . blinds (by others).
These buttons are available only if this function has
been set for the control panel (confi uration of the
room mana ement function).
