Interlock
When two valves are connected with the interlock cable and both valves have reached maximum capacity the valve
displays “system supply water temporary”. When both valves are set to alternate interlock, then one valve is in service
and the other is in standby, the waiting valve screen displays “system wait supplying water”.
Function:
With parallel installation only one valve regenerates at a time. Refer to Figure 8-8.
Figure 8-8 Interlocking a Network of Valves.
Use Interlock cable to connect CN8 to CN7 to the next RevV4 in the series. If one interlock cable is disconnected,
the system is divided into two individual systems.
Alternating Interlock

One valve will always be in service. Refer to Figure 8-9.
