1 General informationThis operating manual describes the EASYLABBE-LCD-01 control panel for fume cupboard controland room control.To ensure complete functioning of the control panelit is essential to read this operating and installationmanual before starting any work, and to complywith it. The manual must be given to the facilitiesmanager when handing over the system. Thefacilities manager must include the manual withthe system documentation.The manufacturer does not accept any liabilityfor any malfunction or damage resulting fromnon-compliance with these instructions or noncompliancewith relevant statutory regulations.Other applicable documentationIn addition to this manual, the following documentsapply:• Control Systems catalogue– EASYLAB BE-LCD-01 control panel– EASYLAB TCU3 controller– EASYLAB TAM adapter module• EASYLAB Configuration Software OperatingManual (M375EV1)• Project-specific wiring documentsSymbols used in this manualDanger!Designates danger to life and limb due toelectrical voltage.Warning!Designates danger to life and limb.Important!Designates danger that can cause minorpersonal injury or damage to property.BE-LCD-01 Operating and Installation Manual / Leaflet no.

2 Safety and correct useGeneral information regarding safetyOnly skilled qualified personnel are allowed toperform the described work on the control panel.Only skilled qualified electricians are allowed towork on the electrical system.For all work performed on EASYLAB components,the following regulations and guidelines must becomplied with. This applies in particular to thefollowing German country specific regulations oras appropriate in the country where the installationis taking place:• Equipment and Product Safety Laws (GPSG)• Industrial Health and Safety Regulations(BetrSichV)• Accident Prevention Regulations (BGV A1,BGV A3)General safety measures• Large temperature differencesCondensation can damage the electronicsbeyond repair. If the control panel has beenkept in an unheated area, wait at least twohours before switching on the supply voltagefor commissioning.• Electrostatic chargeElectrostatic charge can damage the electronics.To avoid this, first touch an equipotentiallybonded metal surface, e.g. a water pipe, forelectrical earthing before you remove the controlpanel from its protective wrapping.• Fixing the base plate and the adapterTighten the screws only hand-tight in order to notdamage the base plate or the adapter.• Foreign matter and liquidsIf liquid gets inside the control panel, letthe control panel completely dry beforecommissioning. Remove foreign matter, if any.If the device emits a smell or smoke, have itchecked by the manufacturer.Correct useThe BE-LCD-01 control panel is an EASYLABcomponent intended for the display of values andfor performing various functions. If the control panelis connected to a fume cupboard controller, thefunction display complies with EN 14175; operatingfunctions and special functions can be set bythe user. If a room is equipped with EASYLABcontrollers, the control panel is intended formonitoring and for operating mode default setting.• Connect the control panel to an EASYLAB TCU3used for fume cupboard control (equipmentfunction FH-xxx).• Connect the control panel to a EASYLAB TCU3controller used for extract air control (equipmentfunction RE), supply air control (equipmentfunction RS), or room pressure control(equipment function PC).• Connect the control panel to an EASYLAB TAMadapter module with active room managementfunction (RMF).• Surface mount the control panel onto the sideframe of the fume cupboard.• As an alternative, mount the control panel to awall, with our without junction box.• Observe the technical data for the control panel.Incorrect useDo not use the control panel outdoors, in wet areas,or in potentially explosive atmospheres.Residual risksA failure of the supply voltage is indicated on thecontrol panel only if the EASYLAB controller isequipped with the EM-TRF-USV expansion moduleand the battery pack has been connected and fullycharged.4 BE-LCD-01 Operating and Installation Manual / Leaflet no.

5 Operation · Fume cupboard controlOverriding operating mode defaults setby the central BMSOperating mode default settings from the centralBMS or from the room control panel can beoverridden on the control panel for the fumecupboard controller.Temporary overrideA centrally set operating mode can be temporarilyoverridden at any time using the operating modebutton on the control panel. The operating modeselected on the control panel remains active untilthe central BMS sets another operating mode. If thecentral BMS sets a different default operatingmode, it overrides the locally activated operatingmode.Manual control for permanent overrideA centrally set operating mode can bepermanently overridden on the controlpanel. To do so, first activate manualcontrol by pressing the correspondingbutton to prevent further overrides fromthe central BMS. Then set any other operatingmode on the control panel.This operating mode default setting can beterminated by pressing the manual control buttonagain. The fume cupboard controller then resumesthe previous operating mode from the central BMS.Manual operation can be set for a limited period oftime. The manual mode will then automatically bedeactivated after the set delay and the previousoperating mode will be resumed.No override optionThe central BMS can suppress overrides from thecontrol panel temporarily or permanently. In thiscase, manual control cannot be used, and thecontrol panel shows only the centrally set operatingmode. If a user attempts to change the operatingmode on the control panel, the active operatingmode will blink briefly.Automatic sash deviceThese buttons are used to control the automaticsash device.The buttons can be used only if an automatic sashdevice has been configured.Open the sashClose the sash.Fume cupboard lightingThis button is used to control the fumecupboard lighting.The button can be used only if thisfunction has been configured.10BE-LCD-01 Operating and Installation Manual / Leaflet no.

6 Installation and electrical wiringFor installation, wiring, and commissioningobserve the recognised technical regulations,especially safety and accident preventionregulations.For any wiring work follow the national and localregulations and guidelines for electricalinstallation.Danger!Danger of electric shock! Do not touch anylive components! Electrical equipmentcarries a dangerous electrical voltageduring operation.• Only skilled qualified electricians areallowed to work on the electrical system.• Switch off the power supply beforeworking on any electrical equipment.Important!Danger of injury or of damage to electricalcablesFold or deburr the edges of the side framecut-outs.MountingThe control panel can be mounted with or withoutthe adapter. Types of installation include:• Using the pluggable adapter which can providefour different viewing angles: from the right, fromthe left, from top, from bottom• Wall installation using a junction box• Installation to a wall or to furnitureFixing screws• For the pluggable adapter, 4 fixing screwsØ 4 mm. The screws should be selectedaccording to the material of the side frame.Screws should be as short as possible to preventdamage to the cable that runs inside the sideframe.• Wall installation using a junction box: Use thescrews supplied with the junction box.• Installation to a wall or to furniture: 4 fixing screwsØ 4 to 4.5 mm. The screws should be selectedaccording to the surface for which they are used.Connecting cableIf there is a considerable distance between thecontrol panel and the controller, you may want touse a network patch cable type S-FTP with amaximum length of 40 m instead of the supplied5 m cable.Hole template for mounting the control panelonto an adapter64 204 × Ø3 mmHole template for mounting the control panelto a wall or to furniture13.5 1194 × Ø4 mm11127.55020543011115 84 1255 2054 208612.559 27.527 105.512.5145145BE-LCD-01 Operating and Installation Manual / Leaflet no.

6 Installation and electrical wiringMounting on an adapterHow to proceed1.Create a cut-out and drill any necessary holesinto the side frame or furniture wall.2.Lay the cable for the connection of the controlpanel with the controller. Take the control panelend of the cable and pass it carefully from therear through the side frame.
