Electrical connections
The power supply has to be connected to and . is considered as system ground.
Unless different transformers are used, special precautions need to be taken.
NOTE:
The aSENSE VAV signal and power supply grounds are common
The same ground reference has to be used for the aSENSE VAV 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 VAV can deliver both a voltage or a current loop for Out(1) / Out(2). For Out(4) a
voltage output or an open collector output is selected with jumper OUT4. 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 and
current output, can have start points 0 % (0-10 VDC or 0-20mA) or 20% (2-10 VDC or 4-20mA)
selected from PC software. See the user manual.
Note 3: Current of Open Collector is internally returned to terminal.
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.
