- Page 22 MODEL F71B/F71G/F67C/F67G/N75A/N75B A. Signal Output Connector 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.
- Page 23 MODEL F71B/F71G/F67C/F67G/N75A/N75B Function: When inlet pressure is high, install a solenoid valve on inlet to ensure valve switching properly. When valve is exactly at position of Service, Backwash, 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.
- Page 24 When valve in backwash cycle, inlet always has water no matter what is water condition in water tank. As Runxin valve no water pass outlet in regeneration cycle, it ensure no water fill into brine tank.
- Page 25 MODEL F71B/F71G/F67C/F67G/N75A/N75B 4） Control Inlet Booster Pump( Set b-01) Instruction: If inlet water pressure is less than 0.15MPa, which makes rinse drawing difficult, a booster pump is suggested to be installed on inlet. Control mode b-01. When system in regeneration cycle, booster pump is open, the wiring refer to Figure 3-8.IF the booster pump current us bigger than 5A, system need to install an contactor, the wiring refer to Figure3-9...
- Page 26 C. Pressure Relief Output Runxin valve will cut off feeding water to drain line when it switches in rinsing cycles. Thus in some water treatment system, e.g. Deep Well, one booster pump was installed on the inlet to increase the system water feeding pressure, this cut-off will cause pressure on inlet rinsing too fast to damage the valve.
- Page 27 MODEL F71B/F71G/F67C/F67G/N75A/N75B D. Remote Handling Connector Online TDS meter monitors treated water other than a flow meter, or PLC controls the rinsing time. When the controller receives a contact closure from above instruments, rinsing begins. The wiring refers to Figure3-12.
