RO ke andar do chhote switch hote hain jo dikhne me milte-julte hain par kaam bilkul ulta karte hain — LPS aur HPS. In dono ko samajhna RO wiring ki sabse zaroori baat hai.
LPS (Low Pressure Switch)
Inlet line par laga hota hai. Jab tak supply me pani ka pressure hai, ye "closed" rehta hai aur bijli aage jaane deta hai. Pani khatam hua to "open" — pump band. Isse pump sookha chalkar kharab nahi hota.
HPS (High Pressure Switch)
Tank ki line par laga hota hai (pressure tank wale RO me). Tank bharne par pressure badhta hai aur HPS supply kaat deta hai. Wall-mount RO me yahi kaam aksar float switch karta hai.
Multimeter se testing
- Plug nikalo, switch ke dono taar alag karo.
- Multimeter continuity/beep mode par rakho.
- LPS: Inlet me pressure ho to beep (closed), pani band karo to beep band (open).
- HPS: Tank khaali/kam pressure par beep, tank full par beep band.
- Ulta ho ya hamesha ek jaisa rahe to switch kharab.
