Boot-up and Initialization Process
Boot-up and Initialization Process
1 Firmware Boot Process.
a Start Boot Loader.
b Boot main firmware.
OR
Boot resident firmware (if set in VRAM, by DIP switch or if
no/wrong main FW is found).
2 Initialize Transport Unit.
a Switch injection valve to bypass position.
b Find initial positions for X,Z and theta motors.
c Check belt tension of theta motor.
d Determine transmission ratio for X and theta axes.
• Turn needle carrier fully counter- clockwise (= theta min).
• Move X-slide into left end-stop (= X min).
• Move X- slide into right end- stop (= X max).
• Rotate needle carrier fully clockwise (= theta max, happens at the
same time as step iii.).
3 Read RFID tag of Sampling Unit.
4 Read RFID tag of sample tray (if tray is different from last time).
5 Move needle into needle seat to determine the seat depth.
6 Move needle into seat (use depth value from step 5).
7 Lower the needle lock.
8 Switch the injection valve to mainpass.
CAUTION
Obstruction of transport unit
Any obstruction of the transport unit during the initialization process will result in a
wrong transmission ratio and thus wrong needle positions.
➔ Make sure no vials or other material gets into the X-slide.
