On/Off Switch
The included ON/OFF toggle switch on
the controller end plate allows for
conveniently switching your ebike on and
off without disconnecting the main battery
pack. When the switch is off, both the
Controller and the Cycle Analyst (if
attached) will power down and cease
drawing current from the battery.
If you want the switch to be accessible from the handlebars or mounted on a
dashboard, then it is possible to remove it from the end plate and extend the
wires up to your desired switch location and then seal the hole with a grommet.
The wire gauge can be fairly thin, but if it is being used with a Cycle Analyst with
light or other accessories powered form the DC jack, then we recommend using
at least 20 AWG.

Regenerative Braking via Ebrake
The Grinfineon controllers have regenerative braking capabilities, allowing you to
use the hub motor as a brake and return kinetic energy back into the battery
pack. This can be achieved either with the ebrake lever for a constant 50%
braking force, or with a 0.0 to 0.8V throttle signal for variable 0-100% braking.
In the first method, you connect an ebrake cutoff lever or other momentary switch
between pins 2 and 4 of the 4-pin ebrake plug (Pin 1 = 4.3V power is useful for
powering Hall Effect ebrake cutoffs). When the ebrake signal is pulled to ground,
then the controller switches to a baseline level of regenerative braking, putting
drag on the wheel and a small amount of current in the battery pack.

The intensity of this regenerative braking torque is fixed at about 50% of max
regen, and is not affected by applying the throttle.
