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!

.

Residual risks

Failure of the network interface does not affect the con­trol function of the volume flow controller but does af
data exchange with the central BMS. Safety-related
applications require further precautions.

fect

1.2 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

Potentially hazardous situation which, if not avoided,
may result in property damage.

ENVIRONMENT!

Environmental pollution hazard.

1.1 Correct use

Expansion module EM-BAC-MOD provides a BACnet
MS/TP or Modbus R
components as well as for the TROX UNIVERSAL
CONTROLLER.

Use the expansion module for the following devices:

 EASYLAB controller TCU3
 EASYLAB adapter module TAM
 TROX UNIVERSAL CONTROLLER

1.1.1 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

This symbol marks all equipotential bonding connection
points on EM-BAC-MOD.

Residual risks

1.3

EM-BAC-MOD 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 in 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.

–

Only skilled qualified electricians are allowed to
work on live components.

– Equipotential bonding is required.

1.4 Risk of damage to property

Temperature differences

NOTICE!

Risk of damage to property due to large tempera­ture differences

If EM-BAC-MOD has been kept in an unheated area,
condensation may form and damage the electronic
components beyond repair

– Let EM-BAC-MOD warm up to room temperature

before you install it.

Electrostatic charge

NOTICE!

Risk of damage to property due to electrostatic
charge

Electrostatic charge can damage the electronics of
the expansion module.

– Before you remove the expansion module from

its protective wrapping, touch an equipotentially
bonded metal surface, e.g. a water pipe, for elec­trical earthing.

–

Avoid skin contact with any components or
printed circuits on the expansion module or the
main PCB.

– Wear conductive footwear and antistatic clothing.

.

Any work has to be carried out by individuals who can
be expected to carry out their assigned duties reliably
Individuals whose reaction time is delayed due to
alcohol, drugs or other medication must not carry out
any work.

.

1.7 Environmental protection

The following substances and materials which are
hazardous to the environment are used:

Electrical and electronic parts

Electrical and electronic parts may contain toxic mate­rials and substances. These parts have to be disposed
of separately from other waste, i.e. taken to your local
reuse and recycling centre or disposed of by a specialist
disposal company.

Batteries

Batteries contain toxic heavy metals. They are haz­ardous waste and must be taken to a hazardous waste
collection point or disposed of by a specialist company.

1.5 System owner's responsibility

System owner's obligations

EM-BAC-MOD is intended for commercial use. The
system owner is therefore subject to the legal obliga­tions of occupational health and safety regulations.

In addition to the safety notes in this manual, the appli­cable regulations for safety
environmental protection must also be complied with.

Commissioning

Required TCU3 software version

3 Commissioning

Personnel:

Network administrator



Once you have set the configuration switch to adapt
EM-BAC-MOD to the network, the controller and the
network can be commissioned.

Commissioning a BACnet or Modbus network requires
specialist knowledge as well as special network
adapters and software. Only specialist personnel should
do the commissioning.

3.1

Required TCU3 software version

The expansion module EM-BAC-MOD with firmware 4.1
requires the following software versions:

 EASYLAB or adapter module TAM

– Software version 8.0 or higher

 TROX UNIVERSAL CONTROLLER

– Software version 2.1 or higher

The 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 EM-BAC-MOD and con-

. This means that the network is not able to read

troller
out current values from the controller or to send any
values.

You need not adapt the controller configuration with
the EasyConnect configuration software for the
expansion module to work.

Expansion module EM-BAC-MOD-01 15

Interface information

Modbus interface

4.2 Modbus interface

Application

The expansion module EM-BAC-MOD supports the fol­lowing Modbus interface functions in the Modbus pro­tocol settings:

 Modbus is an open serial master-slave communica-

tion protocol which has become a de facto standard
for the industry

 The master (e.g. central BMS) can address a

number of slaves (EASYLAB volume flow control­lers) and use Modbus functions to request informa­tion from individual data points

 Data access is based on numbered data registers

which the master has to define in order to request
data using Modbus functions

 The slave responds by either returning the

requested information or an exception code (error)

 Example: The Read Holding Registers func-

tion (register no. 3) returns the volume flow rate
actual value of the addressed controller

 General information for a Modbus device can be

read out using the Read Device

 1/0 = No default: The central BMS does not default

an operating mode for the controller or room.
The operating mode is set locally

control panel, on the fume cupboard control panel,
or using switch contacts.

If the operating mode is not set locally, the controller
activates standard mode.

 2/1 = Standard mode: Normal operation in the day-

time (in Germany: usually according to DIN 1946,
part 7, 25 m³/h extract air per m² main useful floor
area)

 3/2 = Reduced operation: Low mode in comparison

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

 4/3 = Increased operation: High mode in compar-

ison to standard mode, e.g. in an emergency

 5/4 = Shut-off: Shut-off of the volume flow controller,

e.g. to save energy at night or to shut down the
system
