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.
