2 Safety
Safety notes
Symbols are used in this manual to alert readers to
areas of potential hazard. Signal words express the
degree of the hazard.
DANGER!
Imminently hazardous situation which is due to
live components and which, if not avoided, will
result in death or serious injury due to electrical
voltage.
DANGER!
Imminently hazardous situation which, if not
avoided, will result in death or serious injury
.
NOTICE!
Potentially hazardous situation which, if not
avoided, may result in property damage.
ENVIRONMENT!
Environmental pollution hazard.
Correct use
EM-LON provides a LonWorks interface for
EASYLAB base components.
Use the expansion module only for an EASYLAB
TCU3 controller or a T
AM adapter module.
Incorrect use
Do not use the expansion module for areas of application that are not described in this manual.
Do not use the expansion module:
outdoors
in wet areas
in areas with potentially explosive atmospheres
Residual risks
Failure of the network interface does not affect the
control function of the volume flow controller but
does af
fect data exchange with the central BMS.
Additional safety measures are required for safetyrelevant applications.
Safety signs
The following symbols and signs are usually found
in the work area. They apply to the very location
where they are found.
Electrical voltage
Location where a hazard due to electrical voltage
exists.
Earthing
This symbol marks all equipotential bonding connection points on EM-LON.

EM-LON is a state-of-the-art product and meets
current safety requirements. Residual risks cannot
be excluded, however
, and you should proceed with
caution.
Always observe the safety notes provided in the following chapters of this manual to reduce health
hazards and prevent any hazardous situations.
Electric current
DANGER!
Danger of death due to electric current!
Danger of death if live components are touched.
– Switch off the supply voltage and secure it
against being switched on again before
working on the unit.
–

Functional description
Expansion module EM-LON provides 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 scheme. 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.
The PCB contains terminals for the LonWorks network and a service pin push button with indicator
light.
The expansion module is mounted with a header to
the main PCB of the EASYLAB base component.
To simplify diagnosis during commissioning the
expansion module is equipped with two additional
indicator lights that indicate data traffic on the LonWorks interface.
Standard network variables are used for the communication within the LonWorks infrastructure.
These variables ensure unambiguous data
exchange between the nodes.
For commissioning, it is necessary to link the network variables between the nodes (binding). Project
software is used to link the outputs of a node to the
inputs of other nodes.

DANGER!
Danger of death due to electric current!
Danger of electric shock! Do not touch any live
components!
– Switch off the supply voltage and secure it
against being switched on accidentally
before working on any electrical equipment.
–
Only skilled qualified electricians are allowed
to work on live components.
Expansion module EM-LON is to be fitted into the
casing of a TCU3 controller or T
AM adapter
module.
1.
Electrostatic charge can damage the electronics. For this reason, first touch an equipotentially bonded metal surface, e.g. a
water pipe, for electrical earthing before you
remove the unit from its protective wrapping.
A
void skin contact with any components or
printed circuits on the expansion module or
the main PCB.
2.
Switch of
f the supply voltage to the TCU3
controller or TAM adapter module and
secure it against being switched on accidentally. Then open the cover of the TCU3 or
TAM casing (see instructions for the respective device).

3.
Screw the four distance pieces ① into the
corresponding openings in the TCU3 or TAM
main PCB ② and tighten them (hand-tight
only).

4.
T
ake the pin header ③ and push it with the
longer ends from below through the expansion module ④; push the pin header just far
enough such that the pins protrude slightly
on the upper side.

5.
T
ake the expansion module PCB with the
upside up and position it on the TCU3 or
TAM main PCB such that the pin header ③
is exactly above the corresponding plug-in
base ⑤, and the holes for the distance
pieces are above the distance pieces. Then
press the PCB onto the distance pieces.
In case the positions do not exactly line up,
check whether the pin header is still correctly positioned. Repeat step 2.
If you have pushed the pins too far through
the PCB (step 2), the electrical connection
may not work properly. Repeat step 2.
6.
Fix the PCB using the four fixing screws ⑥.
T
ighten the screws only hand-tight.

7.
EM-LON has terminals for two data cables
of a LonW
orks network. Depending on the
network topology, controllers at the end of a
chain may be connected to one bus, controllers at other positions in the chain may be
connected to two buses.
Strip the insulation from the bus cable (at
least two wires), insert the bare wires into
the terminals and tighten the screws by
hand.
Make sure that the polarity of the conductor
pairs is correct. Incorrect polarity will result
in inverted data signals and hence communication errors.
Fix the data cables to the casing using the
wire clamping bracket.
Connect the shield of shielded cables to the
SH terminals. Within a bus segment connect
the shield only at one point to the earth.
Earthing the shield at every controller will
lead to voltage disturbances.
A maximum of 32 units can be operated on
one network segment. T
o avoid cable reflections, network segments must be terminated
at both ends with 120Ω bus terminal resistors. PCBs of revision 2 and higher allow
you to fit terminal resistors directly onto the
PCB. (see page 17)
Connect the shield of shielded cables to the
SH terminals. Within a chain (channel) connect the shield only at one point to the earth.
Earthing the shield at every controller will
lead to voltage disturbances.
Recommended data cable
Bus cables to TIA 568A, category 5
Belden 8471 or 85102
Cables to DOCSIS specification level IV
JY(St)Y 2×2×0.8 (use only twisted pair
for LON-A and LON-B)
8.
Close the cover of the TCU3 or T
AM casing
(see instructions for the respective device).
Then switch on the power supply to TCU3 or
TAM again.

7 Commissioning / Configuration
Personnel:
Network administrator
Commissioning the LonWorks interface requires
detailed technical knowledge and special software,
e.g. Echelon LonMaker
. Only specialist personnel
should do the commissioning.
Commissioning
①
1.
Press the service pin push button (1) and
download the software for the
EASYLAB LonW
orks node. The software for
EM-LON is available for download on our
website.
Binding
2.
Create the logical bindings for the network
variables to be transferred by EM-LON. As
an alternative, use polling.
Configuration
3.
If necessary
, adjust the configuration
nciMaxSendTime or nciConfig_Occ,
Required TCU3 software version
EM-LON with firmware 4.0 requires that TCU3 software 7.0 or higher is installed on the TCU3 controller or T
AM adapter module.
The TCU3 software version is displayed in the
EasyConnect software, ‘Diagnosis’ , ‘Basic Device’
line.
A product sticker on the main PCB also carries the
software version number (only for version 3 or
higher).
With earlier software versions there is no data
exchange between the expansion module and
TCU3. This means that the network is not able to
read out current values from the EASYLAB device
or to send any values to the EASYLAB system.
You need not adapt the controller configuration
with the EasyConnect configuration software for
the expansion module to work.
8 Interface information
For a description of all LonW
orks interface data
points refer to the configuration manual for EMLON.
