Installation Chapter 1
Connections are performed in the following order.
1. Connect the extension cable (when using the extension cable).
2. Connect the sensor.
3. Connect the XM® module.
4. Verify the connections.
5. Check the gap voltage.
Connect the Extension Cable
Use the following steps to connect the sensor and extension cable.
1. Confirm that there are no foreign objects in the sensor and extension cable
connectors.
Foreign objects in the connector cause faulty connections or faulty
characteristics.
2. Insert the extension cable through the provided insulation sleeve (clear
heat shrink tube).
3. Connect the sensor connector and extension cable connectors, and tighten
the collar by hand.
TIP The connection area of the connector must not be exposed to water or oil. If
water or oil enters the connector, the cable capacity increases, and causes a
loss in sensitivity.
TIP Make sure the color band on the sensor cable matches the color band on the
probe end of the extension cable.
