SenseAir eSENSE Ind Disp CO2 Sensor
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 (DOC) 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 Instructions
- 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!
- 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.
- Attaching the Sensor Box: To the wall plate is done by a snap-in fitting. The wall plate has three hooks that fit in the sensor box. Fasten the screw on the side of the box.
- The Lid Can be Locked: With the screw at the bottom of the sensor box.
Electrical Connection
The power supply has to be connected to ~ +ve and ground is considered as system ground. The same ground reference has to be used for the eSENSE unit and for the DDC/Signal receiver.
The same ground reference has to be used for the eSENSE unit and for the control system!
