3Description
3.1Intended use
The Airflow Alarm monitors pressure conditions in a
suitable duct.
3.2Function
The Airflow Alarm is connected to a fan starter so that
Airflow Alarm starts to monitor automatically and sim-
ultaneously with the fan. The alarm is activated when
the static pressure in the duct is outside preset limits.
The Airflow Alarm can either monitor one particular
exhaust point at a workplace or a group of workplaces
connected to a single air duct leading to the fan.
3.3Main parts
See Figure1. The Airflow Alarm Kit consists of:
1 Airflow Alarm - Control box.
2 Pressure switch. Available as a standard model,
and an ATEX-approved model for zone 2/22.
3 Protection filter.
4 Rubber fitting
5 Flashlight (optional)
6 Cable gland (optional)
3.3.1 Airflow Alarm - Control box
See Figure2. The Airflow Alarm contains a terminal
block that includes connections to:
1 85-230 VAC power supply (Phase 1). Signal in from
fan to activate monitoring.
2 85-230 VAC power supply (Phase 2). Power into
Airflow Alarm.
3 External connection to central surveillance (Op-
tional)
4 Pressure switch
5 External Airflow Alarm devices, such as a flash-
light
NOTE!
Drill an extra hole and install a cable gland if the
Control box is to be directly connected to both
a flashlight and central surveillance. See Fig-
ure1 (6).

4Installation
nstallation, repair and maintenance work is to be car-
ried out by qualified personnel using only original Ne-
derman spare parts. Contact your nearest authorized
distributor or Nederman for advice on technical ser-
vice.
4.1Control box
Figure3 shows the Airflow Alarm and pressure switch
mounted.
1 Pressure switch
2 Airflow alarm
NOTE!
• Before starting installation, an unused volts-
free contact from the fan starter should be
wired through to the Fan ON position.
• The Airflow Alarm control box must be in-
stalled outside the ATEX classified zone.
• The optional flashlight should be situated at
a location visible from the workplace(s) mon-
itored.
• The electrical enclosure should be mounted
near the workplace so that the alarm LEDs
can be clearly seen and noted from the oper-
ator’s working place.
• f the operator does not have a permanent
place or where several working places are su-
pervised by one alarm, a flashlights should
be installed so that the alarm may be clearly
seen from the operator’s working places.
4.2Electrical connections
WARNING!Risk of personal injury
Work with electric equipment is to be carried
out by a qualified electrician.
Figure2 shows the wiring diagram and cabling for ter-
minals for the Airflow Alarm.
Electrical connections between components should
comply with current national regulations.
4.3Monitoring point
WARNING!Risk of personal injury
• f there is flammable dust present, turn off
the fan.
• Eliminate ignition sources such as heat or
sparks.
• Wear a dust mask.
NOTE!
• A non-ATEX-approved differential pressure
switch must be installed outside of an ATEX
classified zone.
• Any screws or other fixings used into the air
duct must not cause any collection of dust/
chips. f the differential pressure switch
housing is conductive, there needs to be con-
tact between the pressure switch housing
and the metal duct or ground.
The monitoring point is selected as follows:
W en monit-
oring Location
One single
workplace Between dust extraction point, such as a suction hood, and a
connection to the duct system.
A group of
workplaces Close to the connection point farthest away from the fan. See
Figure3.
The pressure switch can be mounted on the air duct.
NOTE!
When drilling in air ducts, safety regulations
must be kept in mind.
The hose is connected to the hose connection on the
pressure switch marked with a minus (-) sign. Nothing
is connected to the hose connection marked plus (+)
atmospheric pressure.
4.4Startup
When the fan starts, the alarm is activated, and the
ALARM LED remains lit until 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 protection filter is drilled close to the last
connection point. See Chapter4 nstallation.
2 The maximum airflow according to the order ac-
knowledgement, technical specifications etc.
must be determined and the corresponding air ve-
locity calculated.
3 The air velocity is measured with the planned
number of extraction points open. f the airflow is
larger than (V0), reduce the airflow. For example,
this can be done by inserting a plate in front of the
fan outlet flange to reduce the airflow until the
airflow (V0) planned is reached.
4 At this airflow, the static vacuum at the monit-
oring point (PS0) is measured, and the pressure
monitor is set 10% lower. See Figure4, where the
alarm limit setting is represented with the dotted
line.
EN
13

Airflow Alarm Kit
EN NOTE!
f the pressure switch measuring range
does not cover the setting value required,
the pressure switch is replaced by one with
a relevant measuring range.
5 The main airflow is reduced slowly by inserting the
plate in the fan outlet flange until the alarm is re-
leased.
6 The air velocity is measured and the airflow is cal-
culated. f it is between 90 and 95% of the airflow
specified, the adjustment has been completed.
7 f the airflow is less than 90% of the airflow spe-
cified, set the pressure switch 5% higher, and re-
peat item 5.
8 f the airflow is higher than 95% of the airflow
specified, set pressure switch 5% lower, and re-
peat item 5. t might be necessary to remove the
plate in front of the fan outlet flange.
9 When the adjustment has been completed,
note the following in the control protocol, see
Chapter10Control protocol for Airflow Alarm:
Make a copy of the control protocol for the Nederman
service technician.
5Use
WARNING!Risk of personal injury
f there is work with hazardous substances that
are assigned mandatory exposure limits and
there is a problem with the Airflow Alarm, stop
work immediately and fix the problem.
NOTE!
n the event of an alarm, the red ALARM LED
on the Airflow Alarm control box will be lit, and
any external connected alarm devices will be
activated. Stop work at once, find the cause
of the alarm, and fix the problem. See also
Chapter7Troubleshooting.
The Airflow Alarm limit has been set according to the
arrangement and operating parameters of the partic-
ular extraction system. Normally, the Airflow Alarm
limit will be at 90% airflow per workplace, 100% be-
ing the airflow specified. When monitoring a group of
workplaces, the airflow per workplace is an average
value. The Airflow Alarm limit setting is found in the
control protocol for the exhaust alarm.
The Airflow Alarm begins monitoring as soon as the
fan starter is activated, and monitors pressure condi-
tions in a suitable duct. The alarm is activated when
the static air pressure in the duct is outside the preset
limits.
When the cause of the alarm has been fixed, and the
static pressure in the duct returns to within the nor-
mal range, the alarm will turn off automatically, and
the Airflow Alarm will resume monitoring.
NOTE!
During normal operation, the green ON LED
should be lit, which indicates that the 230 V
source works. f the green ON LED is not lit dur-
ing normal operation, one of the 230 V sources
is defective and the red POWER FA LURE LED
will also be flashing. The 230 V source must be
fixed and reconnected at once. f changing a
fuse cannot solve the problem, contact an au-
thorized Nederman technician for assistance.
