Senseair eSENSE II Carbon Dioxide Transmitter Instruction Manual
Installation Manual
eSENSE II (Disp)
CO2 sensor in a housing for mounting in ventilation ducts
General
The IAQ-sensor product eSENSE II (sensor for wall mounting) is designed to
measure carbon dioxide (CO2) in rooms. 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 (DOC). The two
parallel signal outputs OUT1 (0-10 V) and OUT2 (2-10 V or 4-20 mA) give linear
signals corresponding to the measuring range.
The OUT2 output also indicates the status by setting the output voltage to 1 V
or current to 2 mA when the sensor self-diagnostics detects any error.

To open the wall mounted housing
Figure 1 . Closed housing seen from the top and the side. The housing is opened by inserting a screw driver and pushing to the front side of the housing. The locking hooks will then be released.
Figure 2. Closed housing seen from the side.
The housing is opened by inserting a screw driver and pushing left (to the
front side).
The locking hooks will then be released.
Figure 3. Closed housing seen from the side.
Never push to the right. The locking hooks may and the housing is damaged

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 DOC/signal receiver.
The same ground reference has to be used for the eSENSE unit and for the
control system!

Configuration
jumper for OUT2 output The output OUT2 can be used as a voltage or current output. The output is configured by the jumper on top of the PCB. The configuration of the output can be changed by moving the jumper to the desired position. The output has to be reconfigured before the unit is powered up.
Self-diagnostics
The system contains complete self-diagnostic procedures that are executed
automatically when the sensor is in operation. Sensors with display show a
wrench it an error is fund. The wrench is shown during the first seconds after
power up and if the measuring range 2000 ppm is exceeded. The output OUT2
indicates the same information by setting the output to 1 V or 2 mA.
NOTE: The sensor accuracy is defined at contiruous operation (at least 3 ABC
periods after installation)
