8.3 Inspecting Sensor Cables
1. Disconnect the Sensor Cable
Disconnect the cable from the sensor.
2. Inspect the Cables
Perform a visual inspection, ensure all contacts are in position and intact.
3. Test Cables
If the cable passes inspection and the sensor is still malfunctioning, swap cables with a sensor
that is known to be functioning correctly. After swapping the cable, if the problem follows the
cable it can be concluded that there is a problem with the cable.
4. Contact Bend-Tech Support
Contact Bend-Tech Support for replacement cables.
8.4 Setting a Proximity Sensor
1. Disconnect the Sensor Cable.
Disconnect the sensor cable.
2. Position the Sensor Bolt
Position the sensor bolt directly in front of the sensor. This will require jogging the machine. To
move the axis by hand, power OFF the machine.
3. Check the Gap between the Sensor and Bolt Head
Use a feeler gauge to check the gap
between the face of the sensor and the
bolt head - the gap should be between
1/16 - ⅛ in. A yellow-orange light will
illuminate when within proximity.
4. Adjust the Gap
If the gap is not within spec, loosen
the nuts on the sensor and adjust
accordingly.
5. Tighten the Mounting Nuts
When the sensor gap is correct,
tighten the mounting nuts. Re-check to ensure the gap remained in spec during the tightening
procedure.
1/16 - 1/8 in. gab between
the Sensor and the Bolt
