Electrical connections

The power supply has to be connected to

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

reference has to be used for the A-SENSE unit and for the control system! Unless

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

Note 1:

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

(halfwave rectifier). A single transformer may be used for the entire system.

Note 2: A-SENSE 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.
