CO2transmitter
eSENSE Ind
General
The IAQ-sensor product eSENSE Ind for wall mounting in industrial application are
designed to measure carbon dioxide (CO2). Option -Disp displays the measured CO2
value in ppm (parts-per-million) on the LCD.
The units are designed for connecting to Direct Digital Control (DDC) with 0-10V or
2-10V signal inputs. The two parallel signal outputs Out(1) (0-10V) and Out(2) (2-
10V) give linear signal voltages corresponding to the measuring range.
The 2-10V output also indicates the status by setting the output voltage to 1V or 2
mA when the sensor self-diagnostics detects any error.

Dismounting the wall plate
The sensor is delivered with the wall
plate mounted. The wall plate has to
be removed before the sensor is
mounted onto the wall. Unscrew the
screw on the side of the box.
Wall Mounting Instruction
1) Electrical cable entry: The box has a factory mounted cable entry bushing in
dimension PG9. Never feed more than one cable through each cable entry bushing,
or else gas might leak through!
2) Screw the wall plate onto the wall: The wall plate has holes for three screws.
Drill holes for 3,5mm screws and put dowel into them. Dowels and screws 3,5 x
25mm are included in a plastic bag
3) Attaching the sensor box to the wall plate is done by a snap-in fitting. The wall
plate has three hooks that fit in holes in the sensor box. Fasten the screw on the side
of the box.
4) The lid can be locked with the screw at the bottom of the sensor box.
If for some reason the PCB must be removed it must be handed carefully
and protected from electrostatic discharge! Normally, removing the PCB is
not required.

Electrical connections
The power supply has to be connected to and . is considered as system
ground. The same ground reference has to be used for the eSENSE unit and for the
DDC/signal receiver.
PLEASE NOTE!
The same ground reference has to be used for the eSENSE
unit and for the control system!

Self-diagnostics
The system contains a complete self-diagnostic procedure that is executed
automatically when the sensor is in operation. Sensors with display show a wrench if
an error is found. The wrench is shown during the first seconds after power up and if
the measuring range is exceeded. The output Out(2) indicates the same information
by setting the output voltage to 1V or 2 mA.
Maintenance
The eSENSE is basically maintenance free in normal environments thanks to the
built-in self-correcting ABC algorithm. Discuss your application with SenseAir in order
to get advice for a proper calibration strategy.
PLEASE NOTE!
The sensor accuracy is defined at continuous operation (at least 3 weeks after
installation)
PLEASE NOTE! Electronic products should be disposed of via a suitable
recycling centre.
