Type EM-LON

LonWorks interface for EASYLAB controllers and adapter modules

Expansion module for EASYLAB fume cupboard controllers, room controllers, extract air controllers, supply air controllers, and adapter modules, for the integration of rooms or individual volume flow controllers with the central BMS

LonWorks FTT-10A interface
Communication only using standard network variables (SNVT)
The expansion module is fitted into the casing with the EASYLAB base component
Easy retrofitting
Double-stack terminal blocks for the LonWorks network
Service pin push button and corresponding indicator light

Interface to central BMS

When used on a controller with active room management function (RMF) the module provides also data points for the entire room, e.g. for total volume flows or consolidated alarms
When used on a single controller: data points for volume flow rate, alarm, damper blade position, or others
Centralised operating mode default setting, e.g. night-time operation

Application

Expansion module Type EM-LON for the EASYLAB system
LonWorks FTT-10A interface to the central BMS
Data points for individual controllers or for the room
Room interface: Default setting of room operating modes within the EASYLAB system, increase or reduction of the air change rate, readout of the actual room operating values or evaluated damper blade positions, consolidated alarms
Controller interface: Operating mode default setting for a single fume cupboard controller, readout of individual operating values such as volume flow rates for single controllers, or individual alarms
Can be used with fume cupboard, supply air, extract air or differential pressure controller EASYLAB TCU3 and with adapter module TAM
For use in laboratories, clean rooms in the pharmaceutical and semiconductor industries, operation theatres, intensive care units, and offices with very demanding control requirements
Factory mounted or for retrofitting into the EASYLAB base component casing

Construction features

PCB dimensions and fixing points correspond to the EASYLAB main PCB and the casing
Fixing with screws
Pin header to connect the module to the main PCB of the TCU3 or TAM

Información técnica

The expansion module EM-LON supplements the EASYLAB base components (controller TCU3 or adapter module TAM) with a LonWorks interface to link rooms or individual volume flow controllers to the central BMS.

The LonWorks interface supports the EASYLAB room operating mode concept. It is possible to set operating mode defaults in order to control different volume flow rates for daytime and night-time operation; it is also possible to increase or reduce the air change rate by a certain amount (volume flow rate setpoint change), e.g. to influence the room temperature.

Using the LonWorks interface, an individual alarm management system can be set up by consolidating configurable EASYLAB alarms. The interface also enables the transfer of actual operating values such as volume flow rates and damper blade position for a controller or for all controllers in a room.

Expansion module to supplement an EASYLAB base component (controller TCU3 or adapter module TAM) with a LonWorks interface to link rooms or individual volume flow controllers to the central BMS.

The expansion module includes a LonWorks transceiver FTT-10A (free topology, twisted pair), a service pin push button for LonWorks integration, and indicator lights for 'sending data' and 'receiving data'.

Special characteristics
