Note: Use Interlock Cable to connect CN8 to CN7 on next valve in the
loop.
One system with several valves, if interlock cable is disconnected,
the system is divided into two individual system.
C. Pressure Relief Output
Runxin valve will cut off feeding water to drain line when it switches
in regeneration 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 rising too
fast to damage the valve. Pressure Relief Output can be used to avoid
this problem. The wiring refer to Figure3-10.

D. Remote Handling Connector
Online TDS meter monitors treated water other than a flow meter, or
PLC controls the regeneration time. When the controller receives a
contact closure from above instruments, regeneration begins. The wiring
refers to Figure3-11.
