Yeh guide Micra shot-dosing PCBA installation notes ko easy verification steps me todti hai. Kit kharid chuke users, installers aur remote support team ke liye useful hai.
1. Installation se pehle preparation
- Ek La Marzocco Linea Micra, fully powered off.
- IRIS4 shot-dosing PCBA adapter board, ek 4-pin to 4-pin signal cable, aur ek 2-pin to 4-pin power cable.
- BOOKOO ya Acaia Bluetooth scale, preferably current firmware par.
- IRIS4 remote, ya target yield set karne ke liye SHOTSTOPPER Companion app.
Companion app backup target-yield setting tool ke roop me use ho sakti hai: Android ya iOS. Android me usually working Google services chahiye.
2. Original paddle signal cable locate karein
Machine open karne ke baad original black-white harness connector dhundhein. Yeh paddle action signal carry karta hai. PCBA adapter isi signal path me judta hai aur original machine behavior available rakhta hai.
3. Adapter harness connect karein
Original black-white harness ko Type-C side ke paas adapter connector me insert karein. 4-pin to 4-pin signal cable ko adapter ke lower connector me lagayein. Power cable ka 2-pin end left-side adapter connector me lagayein.
Phir power cable ka 4-pin end matching machine-side position me lagayein, aur 4-pin signal cable ka doosra end machine-side signal position me wapas lagayein. Dono connectors firmly press karein taki loose harness extraction ya paddle detection interrupt na kare.
4. Power-on test aur target yield
Machine power on ke baad Bluetooth scale on karein. Jab PCBA scale se connect hoti hai, onboard LED state change honi chahiye. Daily use me target yield IRIS4 remote se set karein. Remote available na ho to SHOTSTOPPER Companion app temporary setting path hai.
| Item | Recommendation |
|---|---|
| Default target | Factory target 37g hai. Apni dose aur recipe ke hisab se adjust karein. |
| Bluetooth scale mode | BOOKOO scale ko two-point timer mode par set karein. Wrong mode protection flow trigger kar sakta hai. |
| Test method | Prepared portafilter ke saath test karein. Empty cups aur plain water tare aur flow behavior distort kar sakte hain. |
5. Ek shot ke dauran kya hota hai
- Prepared portafilter lock karein, Bluetooth scale stable rakhein, aur scale surface dry rakhein.
- Paddle ko left move karke extraction start karein. Scale auto-tare karta hai aur lagbhag teen seconds count karta hai.
- Agar pehle teen seconds me another tare hota hai, workflow restart karein.
- Paddle ko right wapas move karein. Machine extraction continue karti hai, aur PCBA target yield par shot stop karti hai.
- Shot end hone ke baad cup remove karne se pehle lagbhag teen seconds wait karein taki scale settle ho.
Agar pre-infusion enabled hai, pre-infusion end hone ke baad paddle right move karein. Extraction ke dauran target weight se upar scale press karna ya remote shot-curve page par swipe karna bhi immediate stop trigger kar sakta hai.
6. Protection logic aur common symptoms
| Symptom | Action |
|---|---|
| Target yield se pehle auto-stop nahi | Scale mode, PCBA LED state, aur harness fully seated hai ya nahi check karein. |
| Wrong scale mode | Device extraction state me lagbhag 50 seconds ke baad stop ho sakta hai. Protection finish hone dein, scale mode switch karein, phir retry karein. |
| Bahut fine grind 50 seconds se zyada | Protection early stop kar sakti hai. Thoda coarser grind karein ya flow improve karke retest karein. |
| Scale surface par water | Accidental touch-button behavior, tare errors, ya connection confusion se bachne ke liye scale surface dry karein. |
7. Board fix karein aur machine restore karein
Adapter board ko tabhi secure karein jab paddle detection, Bluetooth scale connection, target-yield stopping, aur 50-second protection sab correctly behave karein. Heat dissipation, boiler heat areas, ya moving harnesses block na karein. Machine close karne se pehle make sure shell kisi cable ko pinch nahi karega.
Daily operation, remote gestures, OTA update, aur browser flashing fallback ke liye continue karein User Guide, full online manual, aur OTA Firmware. Accessories purchase ya delivery check karne ke liye open karein Device Store.
