EM-LON 00131144_0

① Plug base for connection with the EASYLAB main PCB
② Terminals for the LonWorks network
③ Service pin push button and corresponding indicator light
④ Indicator lights – data transfer

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.

Communication interface	LonWorks-Transceiver FTT-10A, free topology, twisted pair
Connection to LonWorks network	6 terminals for cable cross sections of 0.12 – 1.5 mm² (LON A, LON B and screen, two of each)

Description of network variables (SNVT)

All variables and parameters are based on standard network variables (SNVT); this ensures integration of the expansion module EM-LON into a LonWorks network.

The equipment functions that support each variable are listed under the special information for that network variable.

Abbreviations

FH: Fume cupboard controller
EC/SC: Extract air controller / supply air controller
RR: Room controller for supply air or extract air
TAM: Adapter module
RR-RMF: Room controller with active room management function
TAM-RMF: Adapter module with active room management function

Operating mode default setting

Input variables nviManOverride (SNVT_hvac_overid), nviOccCmd (SNVT_occupancy) and nviMode (SNVT_state) are available for operating modes
nviManOverride has the highest LON priority
nviMode has the lowest LON priority.
A configuration of the assignment is possible only for nviOccCmd by means of the parameter nciConfig_Occ (SCPTdirection).
The valid binding of an input variable results in a valid operating mode default setting in LON for a single controller or for the room
The invalid binding of an input variable does not result in an operating mode default setting in LON

Operating modes Standard mode

Standard mode means normal operation in the daytime (in Germany: usually according to DIN 1946, part 7, 25 m³/h extract air per m² main useful floor area)

Reduced operation

Low mode in comparison to standard mode, e.g. as a night-time setback

Increased operation

High mode in comparison to standard mode, e.g. in an emergency

Shut-off mode

Shut-off of the volume flow controller, e.g. to save energy at night or to shut down the system

OPEN position

Open position of the volume flow controller

Installation details

Installation and commissioning

Installation

As attachment for the EASYLAB base component: factory mounted
For retrofitting: Mount the expansion module into the base casing
Connect to the LonWorks network

Commissioning

The EASYLAB controller identifies the expansion module automatically
Integrate system with the LonWorks network and link the data points logically (binding) using a network management tool (e.g. Echelon LonMarker, to be provided by others)
Load EASYLAB LonWorks application
Applications are available for download from our website
