Safety Requirements:

This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special
safety advises given in this manual will be adhered to when using the device.

1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other
climatic conditions than those stated under "Specification". If the device is transported from a cold to a warm
environment condensation may cause in a failure of the function. In such a case make sure the device temperature
has adjusted to the ambient temperature before trying a new start-up.

2. General instructions and safety regulations for electric, light and heavy current plants, including domestic safety
regulations (e.g. VDE), have to be observed.

3. If device is to be connected to other devices (e.g. via PC) the circuitry has to be designed most carefully. Internal
connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or
destroying the device or another device connected.

4. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked
accordingly to avoid re-starting.

Operator safety may be a risk if:

- there is visible damage to the device

- the device is not working as specified

- the device has been stored under unsuitable conditions for a longer time

In case of doubt, please return device to manufacturer for repair or maintenance.

5. Warning:
Do not use these products as safety or emergency stop devices, or in any other application where failure of the
product could result in personal injury or material damage. Failure to comply with these instructions could result in
death or serious injury and material damage.

Disposal instructions

The device must not be disposed in the regular domestic waste.
Send the device directly to us (sufficiently stamped), if it should be disposed. We will dispose the device appropriate and
environmentally sound.

1 Installation

1.1 Dimensions 1.2 Elbow-type plug installation instruction

To mount the connection cable (3-, or 4-wire depending
on type of device) the elbow-type plug screw has to be
loosened and the coupling insert has to be removed by
means of a screw driver at the position indicated (arrow).
Pull out connection cable through PG glanding and
connect to the loose coupling insert as described in the
wiring diagram. Replace loose coupling insert onto the
pins at the transducer housing and turn cover cap with PG
glanding in the direction desired till it snaps on (4 different
starting positions at 90° intervals).
Re-tighten the screw at the angle plug.

2 Operation

2.1 Display functions

2.1.1 Currently measured values: During normal operation the CO2 display value is displayed in ppm.

2.1.2 Min/Max Value Memory

watch min values (Lo): press ‘down‘(2) shortly once display changes between ‘Lo‘ and Min values
watch max values (Hi): press ‘up‘(3) shortly once display changes between ‘Hi‘ and Max values
restore current values: press ‘down‘(2) or ’up’(3) once again current values are displayed
clear min values: press ‘down’(2) for 2 seconds Min values are cleared. The display shows shortly ‘CLr‘.
clear max values: press ‘up’(3) for 2 seconds Max values are cleared. The display shows shortly ‘CLr‘.

After 10 seconds the currently measured values will be displayed again.

2.1.3 Min/Max Alarm

Whenever the measured value is exceeding or undershooting the alarm-values that have been set, the alarm-value and
the meas. value will be displayed alternating.

AL.Lo the lower alarm boundary is been reached or is undershot
AL.Hi the upper alarm boundary is been reached or is exceeded

3 Configuration

In the configuration the devices parameters can be changed.
The jumper has to be set, p.r.t. figure right-hand side. To set or remove
jumper, the housing cover has to be removed. Ex works the jumper is set.

To change parameters press “SET” (key 1) four seconds, then the
parameter selection is started with the first parameter (display shows
“dA.Lo”).

By pressing “SET” the desired parameter is selected, the editing of the
parameter values happens via keys 5 (key 3) or 6 (key 2).

Pressing “SET” again (after editing the parameter values) returns to the
parameter selection.

Pressing “SET” again after the last parameter finishes the configuration,
stores the changes and the instrument returns to the normal mode.

3.1 Description of configuration parameter:

a) 'AL.Hi': Upper boundary of alarm

At Al.Hi the boundary is set from which max. alarm will be given.
Selectable range: ‚AL.Lo‘ ... 2001

If the jumper is removed from the shown
contacts, the configuration is inaccessible,
values are protected.

Jumper

b) 'AL.Lo': Lower boundary of alarm

At Al.Lo the boundary is set from which min. alarm will be given.
Selectable range: -1 ... ‚AL.Hi‘

c) 'A.dEL': Alarm delay

The value at A.dEL declares the alarm delay in minutes.

e) 'OFFS': Offset of CO2-measuring

The offset of the measuring will be shifted by this value, the input is in ppm.
Selectable range: -200...+200 ppm or 'oFF': offset is deactivated (=0, ex works)

(calculation: see by scale)

e) 'SCAL': Scale correction of CO2-measuring

The scale of the measuring is changed by this value.
Selectable range: -10,00...+10,00 or 'oFF': scale is deactivated (=0, ex works)

The adjusting by offset and scale is intended to be used to compensate deviations of the CO
It is recommended to keep the scale correction deactivated (“oFF”). The display value is given by following formula:

CO2-display = measured value – offset

With a scale correction the formula changes:

CO2 display = (meas. value - offset) * ( 1 + scale correction/100)
