Mounting Instruction
Since there might be a substantial pressure difference in duct mounting applications, it is essential to
avoid ambient air from suction into the duct mounting box. For correct function it is indispensible that
the sealing of the box cover, the cable entry bushings, the cable feed through and the duct entrance
are absolutely tight. The duct entrance may need extra sealing paste in order to prevent leakage. The
PCB must be handed carefully and protected from electrostatic discharge.
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) Mounting the tube: Drill a hole (10) with 25 mm diameter (or 1 inch) for the sampling probe and
two holes with 4 mm diameter for the screws (5) into the air duct and mount the tube (1) with the
gasket (2). The sampling probe should be mounted with the largest locking knob on top. The unit
can be mounted with the air coming from the left or right.
3) Attaching the sensor box is made to the sampling probe by a snap-in bayonet fitting. First,
carefully stick the temperature probe (11) into the sampling probe. (1). Orient the box onto the
sampling probe so that the box upside is on the same side as the largest locking knob (3). When
the probe is fitted into the notches of the box, then turn the box clockwise until stop (see Figure
1). Position 1 indicates open where the box can be removed from the sampling probe. In position
2 the box is locked to the probe.
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
NOTE:
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
Duct unit and for the control system! Unless different transformers are used, special precautions need to
be taken.
The aSENSE signal and power supply grounds are common.
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 function manual.
