Installing Probe/Thermistor Interface Module - I.S. Bay
Figure 3. Probe/Thermistor Interface Module Wiring
1. Turn Off power to the console. Open the right-hand door of the console. If you are replacing an existing Probe/
Thermistor Interface module, tag the probe wires with their positions, as you remove them from the old module.
Remove the old module.
If you are adding a new module, remove the blank plate from one of the unused I.S. slots.
2. Hold the new module with its snap-in fasteners positioned in the lower right and left corners and carefully slide
the module into its I.S. bay slot until its connector engages with the connector on the board.
3. Press down on the snap-in fasteners to secure the module. BE SURE ALL UNUSED SLOTS are covered with blank
snap-in plates.
4. Connectors are supplied with each module. They provide screw terminations for up to four Mag probes and up to
four Thermistors.
5. If replacing an old module, reconnect the tagged wires in exactly the same connector position on the new module
as they were in on the old module.
If adding a new module, connect two marked or color-coded wires from each Mag Probe (or Thermistor) to the
appropriate terminals on the module as shown in Figure 3. See the table below about device polarity.
6. Ground the shields of each probe wiring pair to one of the console’s ground terminals.
7. Reapply power to the console.
8. Refer to the TLS-3XX Setup Manual to program the Probe/Thermistor Interface Module.
Device Wires Observe Polarity
Mag Probe (up to 4) 2 Yes
Ground temperature thermistor - When using
volumetric line leak detection (VLLD), only
one ground temperature thermistor is needed
per site and the thermistor must be wired to
thermistor position number 1 (positions 2 - 4
are not used).
