5.1 Connecting a Probe
– Thermistor Example
For this example a thermistor probe is used to demonstrate how to connecting one of the accompanying
devices to the unit.
The thermistor probe can be found coiled with the metal probe attached to one end and two exposed wires
(white and red) on the other.
Figure 4 Loosening the Input Glands
Figure 5 Opening Terminals 3 and 4
To attach the probe to the circuit board, loosen the input glands (
above), thread the exposed wires up
the gland until there is enough length for the wire to reach the top of the circuit board, tighten the gland.
Using a screwdriver, press down on the terminal release lever to open terminals 3 and 4 and thread in to
these openings the red and white (respectively) exposed wires (
). If another probe is needed to be
fitted then follow the same procedure but open terminals 5 and 6 and thread in the new red and white wires.
