1） Control Solenoid Valve (Set b-01)
① Solenoid valve on outlet controls water level in brine tank..
Instruction: If system strictly requires no unfiltered water flow from outlet
in rinsing cycle (Mainly for no unfiltered water flow out when valve is
switching. When valve in backwash positions, there is no unfiltered water
flow from outlet), a solenoid valve could be installed on outlet, the wiring
refer to Figure 3-2.
Function:
In service status, if water tank is short of water, solenoid valve is
open to supply filtered water, but if water tank has enough water,
solenoid valve is closed, so no filtered water supplied.
When the valve is in backwash status, there is no signal output. So,
solenoid valve is closed, and no unfiltered water flow into the tank.
② Solenoid Valve on inlet( Set b-02)
Instruction: When inlet pressure exceeds 0.6MPa, series access a
solenoid valve on inlet. Control mode is b-02. Pressure relieved when
valve switching, the wiring refer to Figure 3-3. As Figure 3-4 shows, it
also can use the pressure relief port to work.
