B. Interlock
Instruction: In the parallel water treatment system, it ensures only one
valve in regeneration or washing cycle and (n-1) valves in service, that is,
realizing the function of supplying water simultaneously and
regenerating individually.
In the series water treatment system which is suited for RO
pretreatment system or second grade Na
+
system, it ensures only one
valve in regeneration or washing cycle and every grade has water when
in regeneration or washing. Wiring refers to Figure 3-9:
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 systems.
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 systems, 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 so fast to damage the valve. Pressure Relief Output can be used
to avoid this problem. The wiring refers to Figure 3-10.
