The following screens provide system feedback. This allows the operator to monitor when and how the backflush cycle
is occurring. It is recommended that the operator adjust the backflush interval timer so that the system backflushes by
time before the pressure differential set-point is reached.
Controller Feedback
Backflush Counter:
The number of backflush cycles that have occurred since the counter
was last reset. This includes cycles initiated both manually and auto-
matically. This counter can be reset by pressing the
ESC
button from
the

screen.

.
Time Since Last Backflush: The amount of time that has elapsed since
the system last backflushed. The time displayed is in hours and min-
utes. This value does not include the elapsed time when the backflush
frequency timer is off (either when the Status Screen reads “
Status:
Off”
or when the controller is physically switched off).
This screen also displays how the last backflush was triggered. There
are three possibilities:
1)
Operator
- the backflush was manually triggered by an operator via
the status screen.
2)
Timer
- the backflush was triggered by time as set on the backflush
frequency screen.
3)
PD gauge
- the backflush was triggered by a high pressure differ-
ential, as set on the PD gauge mounted below the controller enclo-
sure.

Tower Water Backflush: The type of water used for backflushing the
system.

flush only. This setting is Read only, and has no user adjustment.
