4.1 Electrical Definitions
The Supply/Signal terminal locates inside
electronic housing. When making connection,
please open the “transmitter” cover firstly, the
terminal’s definition see as the Figure4.1-1, the
left terminal marked with”+A or –B”is for
supply/signal.
Figure4.1-1
Power is supplied by the signal wires. The Signal/Supply share one
terminal(2wires, no additional supply wire).While you make connection, please
take very carefully to make right connection: the anode of Supply wires
connecting with the anode of Supply teA”on the left, Signal I-out
connecting the signal terminal “-B”.
Be sure the Supply & Signal wires DO NOT connecting with the “TEST”
terminal. Otherwise, it will make the transmitter output loop short and cause the
loop parts turnoff. In case that happens, you could take the emergency method
to short the TEST and Common terminals to recover the normal operation of
the transmitter.
The signal wire do not need to use a shield cable, the twisted-pair couple wire
can get the best effect. Please DO NOT let the signal wire share the same
wire/cable allocation pipe or slot with other equipments power supply wires,
and the signal wire NOT close to the high-power equipments. Using sealing
