2.4.2.2 Sensor Signal Input Connection

Two input ports are provided for signals from the dew-point transmitter and the optional
pressure transmitter respectively. They are connected via a single 6-way push fi t
connector block labelled
The method of connection is as follows:
a. Remove the terminal block from the
b. Strip back the wires of the dew-point transmitter signal cable, exposing
approximately 6mm (0.2") - the use of crimps/wire ferrules is recommended.
c. Insert the + 4-20 mA lead into the
terminal block and tighten the screw.
d. Insert the – 4-20 mA lead into
terminal block and tighten the screw.
e. Strip back the wires of the pressure transmitter signal cable, exposing
approximately 6mm (0.2") - the use of crimps/wire ferrules is
recommended.
f. Insert the + 4-20 mA lead into the
the terminal block and tighten the screw.
g. Insert the – 4-20 mA lead into the
the terminal block and tighten the screw.
h. Check that the wiring has been completed correctly.
i. Push the terminal block fi rmly back into the
