Sensor modules can be replaced when they reach the end of their
service life.
Some early serial numbers have sensor modules with the sensor
rotated 90 degrees from the orientation shown in
To replace a sensor module with a new factory-calibrated one,
follow the steps below:
1. Open the controller’s front cover.
2. Unplug the controllers power connector (refer to Figure 6 ).
3. Unplug the sensor module by pulling the sensor module
firmly away from the main board (Figure 11).
4. Plug the new sensor module into the vacant ‘Sensor 1’
location, then press the module firmly until the nylon
standoff (shown in Figure 11) has ‘snapped’ into the hole in
the bottom-left side of the module board
5. Plug in the controllers power connector.
6. Observe that the front cover indicator is no longer flashing red, and then close the controller’s enclosure.
