Additional Repair Notes
Replacing a sensor flex assembly:
– The Sensor Flex Assembly is supplied straight.
– Create a sharp bend (Figure 6-4): The flex circuit must be bent at a right-angle
where it meets the printed circuit board. It can only be bent after heat has been
applied to it (i.e. using a hot-air gun or a similar device).
Figure 6-4 Creating a sharp bend
– Once this sharp bend has been created, the flex should not be bent at this
point again; to do so may break the tracking within the flex.
– Route and connect the sensor flex assembly: once the sensor flex assembly
has been attached to the power meter; it should be folded to match the route
taken by the assembly being replaced. Heat may be used to assist the folding
of the flex.
