4.2.
Filter configuration (Performa 263)
In filter configuration, the valve body, the camshaft and the controller are identical to the one used for
softening. The only difference is related to the valve configuration.
In filter mode, the injector size installed in the valve does not matter, it is only required to allow intern
pressure balancing during cleaning cycles. Refill flow controller is plugged.
The DLFC used is now related to the tank size and media type.
4.3. Cycle
time
calculation
All the Logix controller range automatically calculates the unit capacity as well as the cycle time.
No calculations are therefore required.
