number. Move to the other sequences and enter the same parameter for all of the sequences that
you wish to participate in the pause process.
Pressure Differential Switch Connection
PD switches are designed to sense the pressure difference between both sides of the filter. Connect
the electrical connection of the PD switch (2 wires) to the condition input of the controller.
Defining reaction delay for the PD switch
Enter System Setup, move down to Cond.x OnDly-Sc (where x is the number of the condition input).
This parameter defines the delay duration from the moment the contact closes until the reaction of
the controller.
Move down to Cond.x OffDly-Sc. This parameter defines the delay duration from the moment the
contact opens until the reaction of the controller (resuming normal irrigation).
Enter the Filter Flush menu, move down to Cond.Input No. and enter the number of the condition
input to which the PD switch is connected.
Define the number of continuous flushes - this number determines how many continuous flushes are
allowed before the controller enter a continuous flushing fault (5 is recommended).
At the PD switch adjust the pressure difference for which the contact is closed and flushing is carried
out (0.5 is recommended).
The Difference between Operating and Start Conditions
Operating condition will start the sequence on an "on" connection and stop the sequence when the
connection goes "off", whilst start condition will only start the sequence on an "on" connection but will
not stop it when the connection goes "off". The sequence will only stop when it finishes the amount
of water or time duration set for its valves.
Checking the Status and Activity of the Condition Input
The status of the 3 condition inputs can be seen in the Service Menu. The 3 condition inputs are
shown as C1, C2, C3 in the third row.
It is also possible to see the condition input status in Sequence Info.
