Drive Switch I Drive Pedal
Function:
The microswitch releases the drive impulse if the seat switch is
simultaneously activated.
The potentiometer controls the travel speed. Increased pressure on
the pedal reduces the resistance and increases the speed.
I2P
When the standard parameters have been set or the potentiometer
changed, the "MIN" and "MAX" potentiometer voltage in the "travel"
parameter must be checked.
(see chapter 6 "Travel parameter setting").
