Cadence Sensor Placement

Postby j_heade » Tue Jun 12, 2018 10:55 pm

What is the correct position of the Elite cadence sensor with respect to the magnet on the crank arm. It appears to be intermittent and I want to make sure I have the placement/installation correct? There is a cone shaped portion to the cadence sensor. What is the positional relationship of the magnet on the crank to the cone shaped portion of the cadence sensor?

The tip of the sensor must be aligned with the magnet.
The magnet must pass as close as possible (max 2mm) to the tip of the sensor.

I've also had a lot of problems with the Drivo´s original cadence sensor. The signal arrived intermittently and, especially after a few minutes of use, the signal lost completely. I tried a sensor from an older Elite trainer (Realaxiom), which according to Elite is compatible, and the same problem occurred. At first it worked, but then the signal was lost. This problem has happened to me with several applications (Elite, RGT, BigRing ...) I do not know if I will be wrong, but it seems that it may be a factory error that affects the trainer itself, rather than the sensor.

the sensor is a simple switch that closes when the magnet pass near the sensor attracting the metal foil.
It's a very simple mechanism.
If you have a tester/multimeter, it's easy to check if the contact close (on the jack) when the magnet pass close.

Usually, we have three possible causes of issues about this:
- the magnet is passing too distant from the sensor, so the foils won't touch (or not always)
- the sensor is broken (the foils are crushed for some reason or the wire is broken)
- the connector in the electronic board is damaged (this may happen if you accidentally stumble on the wire pulling it too much)

If one of this conditions happen, cadence won't be read (or won't be stable).
If cadence is not read, the trainer will use the sensorless cadence algorythm, that works well in standard conditions (smooth pedaling, chain well tensed, not too high cadence with low power...) but can be unstable in not standard conditions.

So, resuming, first of all try to understand if you're in one of the three conditions above (check the distance between the magnet and the sensor, check if the sensor seems broken and look at the connector in the electronic board to verify if it seems to be damaged).
If the sensor seems broken, you can buy another one (or ask our customer care if the trainer is still under warranty). If the connector is damaged, contact as well the customer care for the repair.

Anyone with a picture of the right placement of the cadence sensor for a Real Axiom Wired? For some reason they sent the instructions on a separate piece of paper and I misplaced it.
I need a picture I cant seem to figure out how the right way to attach it with written instructions
