2.4.2.2 Sensor Signal Input Connection

Two input ports are provided for signals from the dew-point transmitter and the
temperature transmitter respectively. They are connected via a single 6-way push fit
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 +ve (4...20 mA) wire into the
on the terminal block and tighten the screw.
d. Insert the -ve (4...20 mA) wire into
the terminal block and tighten the screw.
e. Strip back the wires of the temperature transmitter signal cable, exposing
approximately 6 mm (0.2") – the use of crimps/wire ferrules is recommended.
f. Insert the +ve (4...20 mA) wire into the
on the terminal block and tighten the screw.
g. Insert the -ve (4...20 mA) wire into the
on the terminal block and tighten the screw.
h. Check that the wiring has been completed correctly.
i. Push the terminal block firmly back into the
