- Pin 3 becomes active as soon as you power up the drive unit - if less than udcsw/2 V are measured after 5s it will drop
- Pin 6 becomes active as soon as you give the start signal (12V, pin 23) AND udc>udcsw
In short, pin 3 and pin 6 are being activated since I started without activating the 12V of pin 23
