3 Descripon
3.1 Intended use
The Airow Alarm monitors pressure condions in a suitable duct.
3.2 Funcon
The Airow Alarm is connected to a fan starter so that Airow Alarm starts to
monitor automacally and simultaneously with the fan. The alarm is acvated
when the stac pressure in the duct is outside preset limits.
The Airow Alarm can either monitor one parcular exhaust point at a
workplace, or a group of workplaces connected to a single air duct leading to
the fan.

Airow Alarm Kit

4 Installaon
Installaon, repair and maintenance work is to be carried out by qualied
personnel using only original Nederman spare parts. Contact your nearest
authorized distributor or Nederman for advice on technical service.
4.1 Control box
NOTE!
• The Airow Alarm control box and ashlight must be installed outside the
ATEX classied zone.
• The oponal ashlight should be situated at a locaon visible from the
workplace(s) monitored. See gure 3.
Before starng installaon, an unused volts-free contact from the fan starter
should be wired through to the Fan ON posion.
The electrical enclosure should be mounted near the workplace so that the
alarm LEDs can be clearly seen noted from the operator’s working place. See
gure 3.
If the operator does not have a permanent place or where several working
places are supervised by one alarm, one ashlight should be installed so that
the alarm may be clearly seen from the operator’s working places.
4.2 Electrical connecons
WARNING! Risk of personal injury.
Work with electric equipment is to be carried out by a qualied electrician.
See gure 2 for the wiring diagram, and cabling for terminals for the Airow
Alarm.
Electrical connecons between components should comply with current
naonal regulaons.
4.3 Monitoring point
WARNING! Risk of personal injury.
• If the there is ammable dust or gas present, turn o the fan.
• Eliminate ignion sources such as heat or sparks.
• Wear a dust mask.
NOTE! A non ATEX approved pressure switch must be installed outside of an
ATEX classied zone.
NOTE! Any screws or other xings used into the air duct must not cause any
collecon of dust/chips. If the pressure switch housing is conducve, there
needs to be contact between the pressure switch housing and the metal duct
or ground.
The monitoring point is selected as follows:

Airow Alarm Kit
15
EN
When monitoring Locaon
One single workplace Between dust extracon point, such as a sucon hood, and a
connecon to the duct system.
A group of workplaces Close to the connecon point farthest away from the fan. See gure
3.
The pressure switch can be mounted on the air duct.
NOTE! When drilling in air ducts, safety regulaons must be kept in mind.
The hose is connected to the hose connecon on the pressure switch marked
with a minus (-) sign. Nothing is connected to the hose connecon marked
plus (+) atmospheric pressure.
4.4 Startup
When the fan starts, the alarm is acvated, and the ALARM LED remains lit
unl the required pressure is reached. The ON LED is also lit.
4.4.1 Adjustment
1. A suitable part of the duct is selected, and a hole for the protecon lter
is drilled close to the last connecon point. See secon 4.Installaon
above.
2. The maximum airow according to the order acknowledgement,
technical specicaons etc. must be determined and the corresponding
air velocity calculated.
3. The air velocity is measured with the planned number of extracon
points open. If the airow is larger than (V0), reduce the airow. For
example, this can be done by inserng a plate in front of the fan outlet
ange to reduce the airow unl the airow (V0) planned is reached.
4. At this airow, the stac pressure at the monitoring point (PS0) is
measured, and the pressure switch is set 10% lower, see gure 4.
If the pressure switch measuring range does not cover the seng
value required, the pressure switch is replaced by one with a relevant
measuring range.
5. The main airow is reduced slowly by inserng the plate in the fan outlet
ange unl the alarm is released.
6. The air velocity is measured and the airow is calculated. If it is between
90 and 95% of the airow specied, the adjustment has been completed.
7. If the airow is less than 90% of the airow specied, set pressure switch
5% higher, and repeat item 5.
8. If the airow is higher than 95% of the airow specied, set pressure
switch 5% lower, and repeat item 5. It might be necessary to remove the
plate in front of the fan outlet ange.

9. When the adjustment has been completed, note the following in the
control protocol, see secon 9.ControlprotocolforAirowAlarm:

5 Use
WARNING! Risk of personal injury.
If there is work with hazardous substances that are assigned mandatory
exposure limits and there is a problem with the Airow alarm, stop work
immediately and x the problem.
The Airow alarm limit has been set according to the arrangement and
operang parameters of the parcular extracon system. Normally, the
Airow Alarm limit will be at 90% airow per workplace, 100% being the
airow specied. When monitoring a group of workplaces, the airow per
workplace is an average value. The Airow Alarm limit seng is found in the
control protocol for the exhaust alarm.
The Airow Alarm begins monitoring as soon as the fan starter is acvated,
and monitors pressure condions in a suitable duct. The alarm is acvated
when the stac pressure in the duct is outside the preset limits.
In the event of an alarm, the red ALARM LED on the Airow Alarm control box
will be lit, and any external connected alarm devices will be acvated. Stop
work at once, nd the cause of the alarm, and x the problem.
When the cause of the alarm has been xed, and the stac pressure in the
duct returns to within the normal range, the alarm will turn o automacally,
and the Airow Alarm will resume monitoring.
During normal operaon, the green ON LED should be lit, which indicates that
the 230 V source works. If the green ON LED is not lit during normal operaon,
one of the 230 V sources is defecve and the red POWER FAILURE LED will
also be ashing. The 230 V source must be xed and reconnected at once.
If changing a fuse cannot solve the problem, contact a Nederman service
technician for assistance. See also gure 5.
5.1 Airow Alarm - Control box LEDs

6 Maintenance
Installaon, repair and maintenance work is to be carried out by qualied
personnel using only original Nederman spare parts. Contact your nearest
authorized distributor or Nederman for advice on technical service.
WARNING! Risk of personal injury.
Before restarng, close and reconnect guards, doors/hatches, etc.
When any defecve components are found, they should be replaced, and
the unit re-adjusted by a Nederman service technician. If the Airow Alarm
Control box is defecve, it must be replaced.
Maintenance Monthly/Operang Hours Interval
Check that the green ON LED on the controller is lit
durning normal operaon.

pressure switch and the air duct for clogging. Blow air
to clean if necessary.
Every 3 months or 1,000 hours
Check the Airow Alarm limit seng (*) Every 12 months (annually)
(*) To be performed by qualied personnel.
6.1 Spare parts
Contact your nearest authorized distributor or Nederman for advice
on technical service or if you require help with spare parts. See also
www.nederman.com.
When ordering spare parts always state the following:
• Part number and control number (see the product idencaon plate).
• Detail number and name of the spare part (see www.nederman.com).
• Quanty of the parts required.
7 Recycling
The product has been designed for component materials to be recycled.
Its dierent material types must be handled according to relevant local
regulaons. Contact the distributor or Nederman if uncertaines arise when
scrapping the product at the end of its service life.
If the Airow Alarm needs to be removed, the sensor hole in the duct should
be sealed. If hazardous dust is likely to be present, suitable precauons must
be taken such as the use of goggles, dust mask and gloves.
