HAZARD – DANGEROUS OPTICAL RADIATION
The UV-C lamps of the UV disinfection system
emit UV-C radiation. When properly fitted, they
are concealed; the radiation they emit only acts
on the ambient airflow and is harmless to the
user. However, unprotected visual contact with
the UV-C lamps when switched on must be
avoided at all costs. It could result in painful
conjunctivitis and skin irritation.
HAZARD – DANGEROUS VOLTAGE
Always switch off the control box before opening
the access doors.
The control box must also be secured as set
out in the Heavy Current Ordinance. A qualified
specialist must check compliance with this basic
safety precaution. The manufacturer is not liable
for injury or damage due to a missing or discon-
tinuous earthing system (e.g. electric shock).
The control box may only be used with the
installation components described. Otherwise,
there is a risk of injury or other health problems
from UV-C light.
The control box is only intended for use as
described in this Operating and Maintenance
Manual. Any other use is expressly discouraged.
The manufacturer is not liable for injury or
damage due to inappropriate use.
In the event of a fault on the control box, switch
it off immediately and contact FläktGroup.
1. SAFETY AND HAZARD NOTES
Fig. 1: UV disinfection system, type IB (illustrative example)
2. SCOPE OF DELIVERY
The FläktGroup delivery includes the following installation components*
as standard:
• AHU section include UV-C lamps but not mounted. The UV-C lamps
are delivered in cardboards in the unit.
• Control box
• Safety stickers attached on access doors.
The following components are assumed to be present at the installation
site:
• Power supply
* All components delivered by FläktGroup that come into contact with
UV-C radiation are of UV-C resistant design.
3. FUNCTION
The disinfection system neutralises air-borne bacteria and viruses. The
growth rate of pathogens and the potential risk of infection from them
via the air circulation system is effectively reduced as a result.
During the UV-C disinfection process, the air flows directly over special
lamps (UV-C lamps) that emit UV-C radiation. Irradiation of the air flow
neutralises the bacteria and viruses.
In the version of the UV modules as delivered, the ballasts are
incorporated in the actual modules.
The disinfection is installed in an AHU section upstream/downstream
of a fan. The ballasts are integrated in the stainless steel frames of the
modules This Operating Manual relates to the IB version.

5. DESCRIPTION OF THE COMPONENTS IN CB MINI
The UV disinfection system consists of the following components:
One or more UV modules installed either in the Air Handling Unit. In
addition, installation upstream or downstream of the main part of the
AHU.
• A multi-part safety mechanism, consisting of:
- Door safety switch which causes the UV system to switch off
immediately the inspection doors of the UV-C section are opened.
The UV modules switch back on after a time delay once the door
is closed again.
• Automatic control of the UV modules is via the automatic program
of the AHU system, i.e. via the enable signal. The UV modules are
monitored for power consumption, function and operating hours.
• A control box: This is for controlling the system, counting the
operating hours and monitoring all components of the disinfection
system to ensure they are working properly.
6. REQUIREMENTS FOR SAFE AND EFFICIENT
OPERATION OF THE SYSTEM IN CB MINI
The following requirements must be met for optimum disinfection
efficiency and safe operation of the system.
6.1 Site requirements at the customer’s premises
1. Air of the specified parameters (temperature, speed) must be drawn
or blown through the disinfection modules in a uniform manner.
The UV modules should be distributed uniformly across the cross-
section.
6.2 Installation
1. The manner in which the system is installed must ensure that a
maximum effective ir-radiance of 0.00001 mW/cm
2
is not exceeded
in the occupied zone
2. The air velocity at the UV-C lamps must be approximately 2 m/s.
3. The air temperature measured at the UV-C lamps must be between
-20°C and 50°C. A maximum temperature of 50°C must never be
exceeded.
6.3 Operation
1. Close the inspection door and keep it fully closed during operation
of the system. If the inspection door is open, there is a risk of
optical radiation from UV-C rays. This can cause extremely painful
conjunctivitis and skin irritation.
2. Before opening the inspection door, e.g. for maintenance or cleaning
purposes, the UV disinfection system must be fully switched off and
secured against being switched back on.
3. Make sure that the ventilation system is in good working order.
It should always be switched on during operation of the UV
disinfection system to ensure the bacterial and viral rate is kept to a
low level.
4. The mechanical safety components (limit switch and, where
applicable, pressure monitor) must be cleaned so that they are
completely free of any residue. Please follow our notes on cleaning
and maintaining the UV-C lamps and the safety mechanism
(chapter 16).

Wiring notes:
Always make sure that the cable is connected only using the cable
glands intended for the purpose. If the wiring connection differs from
that indicated in the mechanical layout, the controller may malfunction
or other devices in the vicinity may be impaired. No wires may be
connected across the electronics inside the housing. Control and
signal cables must never be routed in the same cable duct or harness
as cables that carry loads – this also applies outside the housing. All
cables must be dimensioned according to the standard for current
capacity.
Use as intended:
This controller has been developed to control UV-C elements. They
are switched based on external control switches and their function is
monitored.
Connection of up to four module frames with lamp outputs up to 2000
VA (4 x 500 VA) is permitted. The device is of modular design and
consists of:
A control box accommodated in a plastic housing (IP65).
A display unit in an aluminium die cast or plastic housing, depending
on the version.
7.2 Functional description CB Mini
After switching on the power supply (main switch), the system starts
in automatic mode.
The green “On” LED on the front of the display element and a “ready for
operation” relay output indicate that the controller is ready for operation
(relay contact is closed).
Activation and deactivation of the control electronics is via the “On/Off”
button on the display element.
Attention!
Only auxiliary power is enabled.
The system can only be enabled via the main
switch.
Attention!
Make sure adequate protection against
electrostatic discharge is provided when installing
the device.
Installation notes:
Make sure that the device is installed as far away as possible from
major sources of interference. Examples are solenoid coils, transform-
ers, frequency inverters, etc.
Attention!
If no faults are present, the lamps illuminate after
a delay of approximately 1 minute and all other
LEDs on the display unit go out.

Installation and Maintenance
FläktGroup DC_10548GB 20220221_R1 Specifications are subject to alteration without notice
If a fault is present – e.g. access door is open, there is a pressure drop
in the fan, there is an external fault message for a module, lamp cur-
rent is low (the lamp current is continually monitored via an integrated
power measurement on the electronics unit) – the relevant LED on the
display unit comes on and “fault” is output via a relay contact (quies-
cent current contact, opens when there is a fault).
If a fault is present on the door switch or the vacuum/fan monitor, the
UV-C lamps immediately switch off automatically, and, after a delay
(2 seconds), a fault message is output via the “fault” relay contact. All
other faults are only indicated on the operating unit and have no further
influence on operation of the lamps.
A faulty lamp is indicated with a 4-minute delay.
The system will not start up again until the fault is rectified; it will then
start automatically after a 1-minute delay.
An internal operating hours counter monitors lamp lifetime.
If the yellow “change UV lamp” LED on the display unit flashes, this
indicates that the lamp will soon have to be replaced. This is generally
once there are fewer than 500 hours of operating time remaining.
Contact FläktGroup for ordering spares.
Once the maximum recommended operating time has finally elapsed,
the yellow “change UV lamp” LED lights up continually (but the system
will remain ready for operation).
Attention!
Parts of the controller are live.
Make sure that you do not touch them.
7.3 Measuring the lamp current for monitoring the lamps
Make sure the lamps have first heated up to their operating
temperature (lamps should have been operating for at least five
minutes) before starting this measurement process, so that the rated
power input is reached.
1. Switch off the power supply to the controller using the “On/Off”
button on the display unit.
2. Set the internal dip switch S2-1 to “ON” (ignore the fault messages
for the pressure monitor and door switch).
3. Switch on the power supply to the controller using the “On/Off”
button on the display unit.
4. Then briefly press the internal button “S1”.
All lamps are switched on and should light up.
Now the power input of the lamps is measured automatically,
signalled by the “UV lamp” LED flashing. This process may take up
to 20 seconds.
Once the lamp current has been successfully calibrated, this LED
goes out.
If the lamp current could not be measured correctly, this LED will
light up continuously for approximately 5 seconds. Check that the
lamps work and repeat this process if necessary.
5. Switch off the power supply to the controller using the “On/Off”
button on the display unit.
6. Reset the dip switch S2-1 to “OFF”.
7. Press the “On/Off” switch to switch the system to operating mode.
The green “On” LED must come on
Attention!
The lamp current must be remeasured each
time a lamp is replaced.
7.4 After replacing a lamp, reset the operating hours counter.
1. Switch off the controller by pressing the “On/Off” button on the
display unit.
2. Set the dip switch S2-2 to “ON”.
3. Switch on the controller by pressing the “On/Off” button on the
display unit.
4. Then hold down the internal button “S1” for approximately
10 seconds.
During this time, the yellow “change UV lamp” LED will flash.
If resetting of the operating hours counter was successful, this lamp
will go out.
If resetting of the counter was unsuccessful, the “UV lamp” LED will
flash briefly.
5. The button can be released.
6. Switch off the power supply to the controller using the “On/Off”
button on the display unit.
7. Reset the dip switch S2-2 to “OFF”.
8. Press the “On/Off” switch to switch the system to the normal
operating modes again.
The green “On” LED must come on.

9. DESCRIPTION OF THE COMPONENTS IN CB MAXI
The UV disinfection system consists of the following components:
One or more UV modules installed either in the Air Handling Unit. In
addition, installation upstream or downstream of the main part of the
AHU.
• A multi-part safety mechanism, consisting of:
- Door safety switch which causes the UV system to switch off
immediately the inspection doors of the UV-C section are opened.
The UV modules switch back on after a time delay once the door
is closed again.
• Automatic control of the UV modules is via the automatic program
of the AHU system, i.e. via the enable signal. The UV modules are
monitored for power consumption, function and operating hours.
• A control box: This is for controlling the system, counting the
operating hours and monitoring all components of the disinfection
system to ensure they are working properly.
10. REQUIREMENTS FOR INSTALLATION AND
EFFECTIVE OPERATION OF THE DISINFECTION
SYSTEM IN CB MAXI
The following requirements must be met for optimum disinfection
efficiency and safe operation of the system.
10.1 Site requirements at the customer’s premises
1. Air of the specified parameters (temperature, speed) must be drawn or
blown through the disinfection modules in a uniform manner.
The UV modules should be distributed uniformly across the cross-
section.
10.2 Installation
1. The manner in which the system is installed must ensure that a
maximum effective ir-radiance of 0.00001 mW/cm2 is not exceeded in
the occupied zone
2. The air velocity at the UV-C lamps must be approximately 2 m/s.
3. The air temperature measured at the UV-C lamps must be between
-20°C and 50°C. A maximum temperature of 50°C must never be
exceeded.
10.3 Operation
1. Close the inspection door and keep it fully closed during operation
of the system. If the inspection door is open, there is a risk of optical
radiation from UV-C rays. This can cause extremely painful conjunctivitis
and skin irritation.
2. Before opening the inspection door, e.g. for maintenance or cleaning
purposes, the UV disinfection system must be fully switched off and
secured against being switched back on.
3. Make sure that the ventilation system is in good working order. It should
always be switched on during operation of the UV disinfection system
to ensure the bacterial and viral rate is kept to a low level.
4. The mechanical safety components (limit switch and, where applicable,
pressure monitor) must be cleaned so that they are completely free of
any residue. Please follow our notes on cleaning and maintaining the
UV-C lamps and the safety mechanism (chapter 7).

Changes reserved
Intended use
This control was developed for installation into an exhaust hood to
control UV-C elements. They are switched depending on external
control contacts and their functions are monitored.
Up to 3 fields with 4 frames each with lamp outputs up to 2000VA can
be connected. The device is set up modular and consists of:
• A control box installed in a plastic housing (IP65)
• A display unit in a plastic housing
Function description
After activation of the power supply (main switch), the system starts
into automatic mode.
The green LED “On” in the front of the display element and a relay
output “Ready for operation” signal the readiness for operation of the
control (relay contact is closed).
Activation and deactivation of the control electronics takes place via
the button “On/Off” in the display element.
Attention!
Only auxiliary energy is switched.
If a fault is present, e.g. door open, pressure drop in the fan, external
fault message of the module, lamp current undercut (the lamp current
is continually monitored via an integrated power measurement on the
electronic unit), is signalled via the corresponding LED in the display
unit and output via a relay contact “Fault” (quiescent current contact,
opens in case of error).
Attention!
If no faults are present, the photozone lamps
are switched on after a delay time of approx.
1 minute and all other LEDs in the display unit
have gone out.

Installation and Maintenance
FläktGroup DC_10548GB 20220221_R1 Specifications are subject to alteration without notice
In case of fault of the door switch or the underpressure or fan
monitoring, the photozone lamps are switched off automatically at
once and an error message is output via the relay contact “Fault”
after a delay time (2 seconds). Any other faults are only signalled in
the operating unit and do not influence the operation of the lamps any
further.
A defective UV lamp is signalled with a delay of 4 minutes.
Only after removal of the fault will the unit start up again automatically
after a delay time of approx. 1 minute.
An internal operating hours counter monitors the service life of the
photozone lamps.
Flashing of the yellow LED “Change UV lamp” (from < 500 hours
residual runtime onwards) in the display unit signals the pending
necessary exchange of the photozone lamps.
After final expiration of the maximum recommended operating
duration, the yellow LED “Service” lights up continually and you see
the information “Change UV lamp”. The corresponding field is set out
of operation and cannot be swiched on. The other fields with remaining
term of the lamps keep ready for operation.
