9    Drive Control Units 

The drive control is provided with its own diagnosis and self-test.  
Therefore, the function of the drive control is inhibited when the machine is switched 
on if the drive potentiometer is not in its neutral position or is not detected as being in 
neutral. 
The same occurs after the seat contact switch has been opened and is closed again. 
Even when the seat contact switch is closed, the drive potentiometer must be in 
neutral, or rather: detected as being in neutral by the drive control. 
If the drive control detects the drive potentiometer as not being in neutral, it initiates 
flashing signals (LED) on the drive control.
