Symbols used in this manual

This operating and installation manual describes
the EM-TRF and EM-TRF-USV expansion modules
that are used to connect TCU 3 EASYLAB
controllers and TAM adapter modules to a
230 V AC supply voltage.

To ensure complete functioning of the expansion
modules it is essential to read this operating and
installation manual before starting any work, and
to comply with it. The manual must be given to the
facilities manager when handing over the system.
The facilities manager must include the manual
with the system documentation.

The manufacturer does not accept any liability for
any malfunction or damage resulting from non­compliance with the manual or non-compliance
with relevant statutory regulations.

Other applicable documentation

In addition to this manual, the following documents

apply:

• Control Systems catalogue
– EASYLAB EM-TRF, EM-TRF-USV

expansion modules
– EASYLAB TCU3 controller
– EASYLAB TAM adapter module

• EASYLAB TCU3 controller Operating and
Installation Manual (M375EV0)

• Project-specific wiring documents

1 General information

General information regarding safety

Only skilled qualified personnel are allowed to
perform the described work on the expansion
modules.
Only skilled qualified electricians are allowed to
work on the electrical system.

For all work performed on the EASYLAB
components, the following regulations and
guidelines must be complied with. This applies in
particular to the following German country specific
regulations or as appropriate in the country where
the installation is 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 differences

Condensation can damage the electronics
beyond repair. If the expansion module has been
kept in an unheated area, wait at least two hours
before switching on the supply voltage for
commissioning.

• Electrostatic charge

Electrostatic charge can damage the electronics.
To avoid this, first touch an equipotentially
bonded metal surface, e.g.
a water pipe, for electrical earthing before you
remove the expansion module from its protective
wrapping. Avoid skin contact with any
components or printed circuits on the expansion
module or the main PCB.

• Weight

The expansion PCB is equipped with a
transformer that has a comparatively high
weight. To avoid injury and damage, be sure to
grip the PCB properly and to handle it with care.

• Installing the PCB

Tighten the mounting screws only hand-tight to
avoid damage to the PCB or to the fixing points
in the casing.

• Foreign matter and liquids

If liquid gets onto the PCB or inside the expansion
module, let the expansion module completely dry
before commissioning. Remove foreign matter, if
any.

If the device emits a smell or smoke, have it
checked by the manufacturer.

2 Safety and correct use

Correct use

The EM-TRF and EM-TRF-USV expansion modules
are used to connect TCU 3 EASYLAB controllers
and TAM adapter modules to a 230 V AC supply
voltage.

• Use the expansion module only with a TCU3
EASYLAB controller or a TAM adapter module.

• Do not connect EASYLAB controllers with an
EM-TRF or EM-TRF-USV expansion module to
a 24 V power supply.

• Only connect the expansion module to the
dedicated socket on the main PCB of the
TCU3 or TAM.

• Observe the technical data of the expansion
module.

Incorrect use

Do not use the expansion module outdoors, in wet
areas, or in potentially explosive atmospheres.

Residual risks

Uninterruptible power supply is provided only
with the EM-TRF-USV being connected to a fully
charged battery pack. For maximum operating
times with uninterrupted power supply refer to
the technical data.

Functional description

Once the expansion module has been connected
to the 230 V AC supply voltage (mains voltage), the
transformer reduces this voltage to 24 V AC to be
supplied to the controller and its modules. An LED
indicates whether voltage is being supplied.

Additional function of the EM-TRF-USV

If the supply voltage (mains voltage) fails, the
battery pack takes over and supplies voltage to
the controller and any connected components.
The alarm function is always maintained; if the
emergency voltage supply covers also the air
conditioning system, that function is also
maintained.

For installation, wiring, and commissioning
observe the recognised technical regulations,
especially safety and accident prevention
regulations.

For any wiring work follow the national and
local regulations and guidelines for electrical
installation.

Danger!

Danger of electric shock! Do not touch
any live components! Electrical equipment
carries a dangerous electrical voltage.

• Only skilled qualified electricians are
allowed to work on the electrical system.

• Switch off the power supply before
working on any electrical equipment.

Important!

Danger of injury or damage to electronic
parts from the weight of the transformer.

To avoid injury and damage, be sure to
grip the PCB properly and to handle it
with care.

Installing the EM-TRF and EM-TRF-USV

Step 1

1.Interrupt the voltage supply to the TCU3 controller
or TAM adapter module.

2.Open the lid.

3.Slide the 6-pin PCB connection plug  onto the
expansion module PCB. The tiny plastic bridge on
the
plug fits into the cut-out of the expansion module
PCB. Make sure that the plug locks into place.

Step 2

1.Lower the expansion module with the connection
plug into the casing of the TCU3 or TAM and
place it in such a way that the connection plug is
aligned with the appropriate cut-out of the main
PCB.

2.Push the expansion module towards the main
PCB until the connection plug has been firmly
placed in the cut-out, and the fixing points (holes)
of the expansion module PCB and the main PCB
are
aligned.

3.Fix the expansion module with the supplied four
fixing screws.

5 Installation

Fitting the safety latch

For safety reasons the TCU3 casing must be locked
in such a way that it can only be opened with a tool
when a 230 V power supply is connected.

1. Place the supplied safety latch on the casing.

2. Drill a hole into the casing (Ø 3mm).

3. Fix the latch with the supplied screw to the lid of the
casing.

The casing can now only be opened with a tool.

For installation, wiring, and commissioning
observe the recognised technical regulations,
especially safety and accident prevention
regulations.

For any wiring work follow the national and
local regulations and guidelines for electrical
installation.

Danger!

Danger of electric shock! Do not touch
any live components! Electrical equipment
carries a dangerous electrical voltage.

• Only skilled qualified electricians are
allowed to work on the electrical system.

• Switch off the power supply before
working on any electrical equipment.

Wiring the EM-TRF and EM-TRF-USV

• Never connect two voltages!
When the expansion module for 230 V AC is
used, do not connect a 24 V AC/DC voltage to
the main PCB.

• Connect the 230 V AC supply voltage to the
upper terminals.

• Use the lower terminals to connect the
supply voltage for the next controller or for the
fume cupboard lighting control (EM-LIGHT
expansion module).

• Fix all connection cables to the wire clamping
bracket in the casing.

The terminals for the supply voltage carry a code
that identifies their application:

• L: 230 V AC, live wire

• N: 230 V AC, neutral conductor

• PE: protective earth

Wiring the EM-TRF-USV - contd.

• Connect the cable of the battery pack to the
2-pole socket .

• Be careful when connecting any cables so as to
not disconnect inadvertently the measuring tubes
of the volume flow controller.

will be maintained. The EasyConnect configuration
software provides a commissioning wizard that
guides users in making project-specific
adjustments.

• Maintain standard operation, i.e. control function
(factory setting)

• Close the control damper

• Open the control damper

• Hold the last damper blade position

Diagnosis

An LED indicates the operating state of the EM­TRF-USV expansion module.

Maintenance

The EM-TRF and EM-TRF-USV expansion modules
do not require any maintenance.

Disposal of the battery pack

The battery pack of the EASYLAB system is a
rechargeable Ni-Cd battery pack. Only dispose of
batteries in an environmentally sound manner and
in compliance with national and local laws and
regulations.

Batteries as well as rechargeable battery packs
must not be disposed of with household waste.
Consumers are required by law to return them
for recycling.
