Page 10: Electrical Connections
Electrical connections The power supply has to be connected to G+ and G0. G0 is considered as system ground. The aSENSE™ VAV same ground reference has to be used for the unit and for any connected device! Unless different transformers are used, special precautions need to be taken. PLEASE NOTE! The signal ground is not galvanically separated from aSENSE™... - Page 11 aSENSE™ VAV Note can deliver both a voltage or a current loop for OUT1/OUT2. For OUT4 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 OUT1 and one for OUT2, so that one output can be a voltage output and the other a current output.
