solenoid valve is open to supply soft water, but if water tank has enough
water, solenoid valve is closed, so no soft water supplied.
When the valve in backwash status, there is no signal output. So,
solenoid valve is closed, and now water flow into soft water tank.
②Solenoid valve on inlet( Set b-02)
Instruction: When inlet pressure exceeds 0.6MPa, install a solenoid
valve on inlet. Control mode is b-02. Pressure relieved when valve
switching, the wiring refer to Figure 3-2. As Figure 3-3 shows, it also can
use the pressure relief port to work.
Function:
When inlet pressure is high, install a solenoid valve on inlet to
ensure valve switching properly. When valve is exactly in position of
Service, Backwash, Brine& Slow Rinse, Brine Refill and Fast Rinse,
solenoid valve is open. When valve is switching, solenoid valve is closed,
no water flow into valve to ensure valve switching properly. It could
prevent the problem of mix water and water hammer.
Use interlock cable to realize valves in parallel and series in same
system which is suited for RO pretreatment system or second grade Na
+
system. The Wiring refers to Figure 3-4:
