Attaching 'Wired' Sensors/Probes to iSense Transmitters

To Attach ‘Wired’ Sensor(s)Probe(s) to the iSense Unit:

1.Remove the iSense Unit’s front cover.

See Removing the Front Panel.

2.Loosen one of the input glands.

The number of glands will depend on the number of Channels the Unit has and whether the Unit is supplied with an external power supply.

Start with the left-hand gland for the first probe to be added. See  Figure 212 below:

Loosening the Input Gland(s)

3.Thread the probe’s exposed wires through the gland until there is enough length for the wire to reach the Sensor/Probe Connection Terminal at top of the circuit board. See Figure 213 below.

4.Tighten the gland.

5.Using a screwdriver, press down on the Chan A GND Terminal Release Lever to open the Chan A GND (-ve) terminal. See Figure 213 below:

6.Thread the exposed end of the probe’s white wire and the shield into the open Chan A GND terminal. See Figure 214 below.

7.Release the lever.

8.Using a screwdriver, press down on the Chan A + Terminal Release Lever to open the Chan A + (+ve) terminal. See  Figure 212 above.

9.Thread the exposed end of the red wire into the open Chan A + terminal. See Figure 214 below.

Note the Thermistor Probe’s shield connected to the Chan A GND terminal along with the white wire in this example.

10.Release the lever.

11.Repeat Steps 2 – 10 for any further probes for 2 or 3 Channel iSense devices; connecting additonal probes to Chan B GND/Chan B + and Chan C GND/Chan C + terminals respectively. See Table below:
