Photon: Pedal assist not working
Symptoms
No power is being supplied from the motor when pedaling where the throttle and walk assist functions still operate as normal.
Reason
- The torque sensor has failed
- The controller has failed
- There is a firmware-related Issue
- The rotational torque sensor is not connected to the stationary torque sensor.
Checklist
Solution 1
Please check the following:
- Is there a Cadence RPM reading on the CYC Ride Control app? If yes, is it accurate or is it clearly inaccurate?
- Is there a Human Input reading on the app?
If the Cadence RPM is still getting a reading even though it's not accurate, it means that there is still a communication signal from the controller. In this case, the TS (torque sensor) needs to be replaced.
If the Cadence RPM reading is 0, look for other signs of controller failure.
Signs of controller failure include things like not being able to connect to the app, other strange readings, odd power delivery, etc.
*NOTE: Cadence RPM can also be seen on the DS103 and SW102 displays. Human Input can be seen on DS103 but NOT on SW102.
How can we know this?
The Human Input reading is calculated as follows:
(Nm x Avg. Cadence)/ x.xxx
Thus, if there is no torque input, then the Human Input reading will be "0".
