Chaining Amiad Controllers:
In order to operate a battery of screen or gravel media filters that include a larger number of filters than one Amiad’s Flushing
Controller can handle, it is possible to chain few controllers for the job.
The D.P. switch that reads the pressure drop across the battery is connected to the first controller of the chain (the Master). The SEQ
(or End of Cycle) output of the master controller is connected to the D.P. input of the second controller of the chain (the first slave) and
this controller SEQ output is connected to the D.P. input of the nest. This type of connection can be spanned over as many controllers
as needed.
When the actual D.P. switch send a signal the master controller starts a flushing cycle. Once this cycle is completed the master
controller sends a signal through its SEQ output to the second controller to start its flushing cycle, and so on till the last controller in the
chain as illustrated in the following drawing.
