2.2 Connecting a Sensor
To retrofit a non-amplified single channel sensor, you
will need feed the cable into the External Amplifier and
connect the cable to the terminal block.
Firstly, feed the sensor cable through the cable gland
and when in place, finger tighten securely. Be sure
there is enough cable inside the box to reach the
corresponding terminals. The blue wire from the sensor
must be connected to terminal 1 and the green wire
from the sensor must be connected to terminal 2. Next
you will need to connect the grey wire from the sensor
to the white wire found loose inside the External
Amplifier. Now feed these two connected white and
grey wires into terminal 7 of the terminal block and
ensure all are tightened securely. The red sensor wire
is not connected, the end can be taped over and then
tucked under the metal plate. Finally, once the wires are
successfully connected to the terminal block, remove
the silica packet from the plastic bag and place inside
the box before screwing the lid securely in place.
