To operate the bypass one pin for opening and one for closing is used. If both pins should be switched on, this indicates a fast stop to the motor, defined by the full-bridge driver L298.

I experienced that the L298 comes with a voltage drop of 3 V. Therefore, to drive the Bosch VMC 24V of my Bypass, I need a voltage supply of 29 V at least.
