14POINT7 Spartan 3 Lambda Sensor
Tlhokomediso
- Se ke oa hokela kapa oa hakolla Sensor ea Lambda ha Spartan 3 e ntse e sebelisoa.
- Sensor ea Lambda e tla chesa haholo nakong ea ts'ebetso e tloaelehileng, ka kopo ela hloko ha u e tšoara.
- Se ke oa kenya Sensor ea Lambda ka tsela eo yuniti e tsamaisoang ka eona pele enjene ea hau e sebetsa. Enjene e qalang e ka tsamaisa condensation tsamaisong ea hau ea ho qeta ho ea ho sensor, haeba sensor e se e ntse e futhumetse sena se ka baka tšabo ea mocheso 'me sa etsa hore li-ceramic tse ka hare ho sensor li phunyehe le ho senyeha.
- Le hoja Sensor ea Lambda e ntse e le mocheng o sebetsang oa ho qeta matla, e tlameha ho laoloa ke Spartan 3. Carbon e tsoang mokelikeli o sebetsang e ka hahoa habonolo holim'a sensor e se nang matla le ho e silafatsa.
- Bophelo ba sensor ea Lambda ha bo sebelisoa ka mafura a etellang pele bo pakeng tsa 100-500 hrs.
- Spartan 3 e lokela ho ba ka phaposing ea mokhanni.
- U se ke ua khoaela thapo ea lambda.

Bootloader
Ha Spartan 3 e tsamaisoa ntle le LSU Heater Ground e hokahaneng, e tla kenya mokhoa oa bootloader. Ho matlafatsa Spartan 3 ka Heater Ground e hokahaneng ho ke ke ha qala bootloader mme Spartan 3 e tla sebetsa joalo ka tloaelo. Ha Spartan 3 e le ka mokhoa oa Bootloader ho na le LED e ka holim'a sekepe, e ka bonoang ka li-slits, tse tla benya botala bo tiileng. Ha o le boemong ba bootloader, litaelo tsa serial ha li khonehe. Ka mokhoa oa Bootloader, ho ka khoneha feela ntlafatso ea firmware, mesebetsi e meng kaofela e koetsoe.
Ho kenya mokhoa oa bootloader bakeng sa ntlafatso ea firmware:
- Etsa bonnete ba hore Spartan 3 e timme, ha ho na matla a ho Pina 1 kapa Pin 3 ea "screw terminal".
- Tlosa sensor
- Hakolla LSU Heater Ground ho Pin 4 ea theminale ea screw
- Matla ho Spartan 3,
- Lekola hore na LED e ka holim'a sekepe e benya botala bo tiileng, haeba ke ka nako eo Spartan 3 ea hau e leng mokhoeng oa bootloader.
