Filter to reduce noise* reaching the load cell (eRider T9 / eRider T4).
*disturbances sent by the engine controller are received through the unshielded cable of the load cell. Interference causes the freezing of the electronics located in the strain gauge support. It manifests itself in the cessation / disturbance of the support sending information about pressure on the pedal.
This bottom bracket is designed for 250W controllers, where disturbances are very small and the bottom bracket can handle them. However, when installing this support for more powerful drivers, the problem of interference occurs very often. The solution is to add this filter and shielded cable.
- Filters the power supply to the bottom bracket electronics, reducing noise reaching there. This makes it possible to mount this carriage to high-power controllers, e.g. 2000 W, 5000 W, 10000 W etc.*
*This filter does not guarantee 100% noise immunity, and it is possible that these problems continue to occur in a particular vehicle.
- Filters the crank speed signal so that no signal is sent to the controller when the crank is turned backward. Thanks to this, the drive will not engage when we turn the crank backwards.
- for owners of controllers with a power above 1000 W
- for people who notice symptoms of freezing or weakening of the pressure sensor sensitivity
- for people who want to eliminate the effect of the vehicle moving away when turning the crank backwards (note: only works for this bottom bracket eRider T9 / eRider T4)
- The key is to solder the filter plate as close as possible to the bottom bracket (5 cm - 7 cm). Moving the filter every centimeter further reduces its performance drastically.
- An important fact is the use of a shielded cable (with a shielding braid) from the board to the controller. An example of a cable is: LiYCY 6x0.14 mm2.
- It is important to connect the cable shield to ground on the controller side. Note: the cable shielding is connected only on one side.
- The plate should be protected against corrosion, e.g. by wrapping it in a heat-shrinkable sleeve. Additionally, a universal tile varnish can be used, e.g. PVB 60.
