CO2 / temperature transmitter with heater

mounted in industrial housing

aSENSE with heater Mounting of the sensor onto the wall

1 Screw 5x25

2 Dowel

3 Cable entry bushing PG9

4 DIN rail

5 Draining holes

The DIN rail places the sensor 7 mm from the wall. This distance is very important for

the response time because the air inlets are situated at the back of the housing

facing the wall. The sensor should be mounted with the cable entry bushing upwards

and the draining holes downwards.

The sensor PCB is in an extra housing inside the outer housing.

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. If the analogue output is connected to a controller the same ground

reference has to be used for the aSENSE unit and for the control system! Unless

different transformers are used, special precautions need to be taken.

PLEASE NOTE! The aSENSE signal and

power supply grounds are common

NOTE!

The same ground reference has to be used for

the aSENSE unit and for the control system!

Connect the power after mounting. The analogue

output should be connected before measuring.

Note 1: The ground terminal is used as negative power supply DC input or AC phase ground

(halfwave rectifier). The signal ground M, protected by a PTC resistor, is the same as power ground

(permitting a ”3-wire” configuration). A single transformer may be used for the entire system.

Note 2:aSENSE can deliver a voltage or a current loop for Out(1) / Out(2). To change between

voltage and current output mode the hardware jumpers are used. There is one jumper for Out(1) and

one for Out(2), so that one output can be a voltage output and the other a current output. Both, voltage

output and current outputs, can have start points 0 % (0-10 VDC or 0-20mA) or 20% (2-10 VDC or 4-

20mA). The same start point is used for both outputs. See the user manual.
