General
The IAQ-sensor product e
ee
eSENSE (sensor for wall mounting) is designed to measure carbon
dioxide (CO
2
) in rooms. Option - Tr is prepared for temperature measurements by the
resistive temperature probe mounted by the user. The temperature probe is potential free
(floating). Option - D displays the measured CO
2
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 OUT1 (0-10V) and OUT2 (2-10V or 4-
20 mA) give linear signal voltages or currents corresponding to the measuring range.
The output OUT2 also indicates the status by setting the output voltage to 1V or the output
current to 2 mA when the sensor self-diagnostics detects any error.

Closed housing seen from above. Pressing
a screwdriver on the locking hook opens
the housing. The locking hook is then
released.

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 e
ee
eSENSE unit and for the DDC/signal
receiver.
PLEASE NOTE!
The same ground reference has to be used for the e
ee
eSENSE unit
and for the control system!

Self diagnostics
The system contains complete self-diagnostic procedures that are executed automatically
when the sensor is in operation. The yellow LED is lit if an error is found. Sensors with
display show a wrench if an error is found. The wrench is shown and the yellow LED is lit
during the first seconds after power up and if the measuring range exceeded. They are
automatically turned off when the sensor returns to normal operation. The output OUT2
indicates the same information by setting the output voltage to 1V or 2 mA.
Maintenance
The eSense K50
eSense K50eSense K50
eSense K50 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.
