Data sheet: CO2 traffic light housing CO2-A 100 2
The microprocessor-controlled CO2-measuring instrument is used to measure
the CO2 content of the air in the range of 0 to 3,000 ppm. The measuring sig-
nals are optically displayed by 6 colored LEDs.
The CO2 content of the air is determined by means of an optical sensor
(NDIR), non-dispersive infrared technology. By using the sensor according to
the dual principle, disturbances of the measurement by pollution and aging
can be excluded as far as possible, so that a long function time of the device
is ensured. Calibration is not necessary under normal operating conditions.
The application of the CO2 traffic light is particularly recommended in
teaching rooms and conference rooms, as controlled ventilation behavior
keeps the maximum CO2 room air concentration within limits, thus increasing
the ability to concentrate. As a signal effect, an acoustic signal tone can be
switched on at a room air concentration of 900/1,200/1,500/1,800 ppm.

Mounting on wall
1. For mounting on the wall, open the sensor according to the figure below and fix the back plate on the
wall. The mounting location should not be behind the door, near radiators or in a corner. The sensor must
be protected from direct sunlight and magnetic waves.
Connection
2. The connection is made as shown in the figure. Terminals 1 and 2 are
to be used for voltage input, terminals 2 and 3 for output. Caution: Impro-
per connection will destroy the sensor.

First use
After connecting the voltage, the warm-up time starts and the LEDs flash for 30 seconds. During initial start-up (or
when not used for longer than one month), the warm-up time is 24 hours, after which the sensor operates stably.
The normal warm-up time is 5 minutes.

Setting the audible alarm value
As a signal effect, an acoustic signal tone can be switched on at a room air concentration of 900/1,200/1,500/1,800 ppm. For this purpose, the
jumpers DIP 2 and DIP 3 must be set as shown in the figure.
DIP 1 = ON, alarm is switched off
DIP 1 = OFF, alarm is switched on
DIP2 DIP3 Alarm value
OFF OFF 1.500ppm (factory setting)
OFF ON 900ppm
ON OFF 1.200ppm
ON ON 1.800ppm
Self-calibration
The self-calibration can be switched on or off by means of the DIP 4 switch.
DIP 4 = OFF, self-calibration On, (factory setting)
DIP 1 = ON, self-calibration off

Analog output
Before the output is changed, the sensor must be de-energized.
Open the housing as described and change the jumper J1,
and the jumpers S2 and S3 according to the table.
Instruction
1. To protect the infrared CO2 sensor, please avoid shaking or hitting it.
2. During initial start-up or after a longer period of unuse, the CO2 sensor must be switched on continuously
for at least 2 days to ensure that the self-calibration system of the CO2 sensor functions properly.
3. Self-Calibration: The sensor has a self-calibration feature. The sensor self-calibrates every 14 days when
exposed to outside air (400ppm).

Instruction manual CO2 A 100
The CO2 traffic light is supplied with a plug-in power supply unit. Mount
the device on the wall as described in the mounting instructions or with
the wall-mounted table stand supplied as an accessory.
Connect the power plug to the device on the side of the housing. The CO2
traffic light can be used immediately. After the self-calibration (all LEDs
light up) of up to 2 minutes, the device is ready for operation and immedi-
ately displays the CO2- room air concentration.
The colored LEDs light up individually and represent the subsequent room
air concentrations. Additionally, an acoustic signal tone can be switched
on when exceeding 1,500 ppm.
