Explanation:
A, any A valve in the regeneration (backwashing) and cleaning (wash) position is, can send out lock signal
B, any a valve from softening (run) position into regeneration (wash) the location, and whether time mode or flow mode, want to read the interlock online lock, lock signal if signal (that is, other valve in the regeneration or cleaning state), continues to wait for locking signal of the water discharge, then softening (run) lights flashing. Until the other valves (wash) the complete regeneration or cleaning (lifted the lock signal), this valve (wash) the regrowth began and cleaning (wash), and sent out is locked signal.
C, the output of the S1, S2 on board the sequence of each other, not socket lock line can insert in any one place.
D, when only a valve work, can not in interlock line.
E, when DuoGe valve work, if don't need interlock, he did not put interlock line, each valve can work independently.
2£®External control interface
The valve can be through the external other control system control into regeneration (wash), the cleaning (wash) or soften the state is external control system, the voltage signal is given according to the regulated hands is equivalent to a button£¨SHTFT£©.

3£®Relay output interface £¨CC£©
A¡¢the capacity for contacts. Relay 5 A / 250 V.
B. Relay output port, NO beginning, for often COM for the people
C. In connection AC220V power output relays, input to meet leakage circuit breakers.
When output model is 0 (electromagnetic valve mode), relay output can control the electromagnetic valve, the valve inlet inversion, electromagnetic valve is closed, turn a ended, electromagnetic valve opens.

When output model for 1 (booster pump mode), relay output can control the booster pump inlet, in renewable and clean the wash () () position when the wash is mudline booster pump, soften position, open mudline booster pump shut down. Inversion, booster pump shut down.
