FILTRON 1-10 (DC/AC)

List of features

The “FILTRON 1-10” is a modular backflushing controller for automatic filters of 1 to 10

stations.
There exist DC and AC models.
The DC model can be powered either by 6v DC or 12v DC and it activates 2 wired 12v DC

latching solenoids. The voltage for the solenoids switching is boosted by a charge pump.
The AC model contains an internal transformer that can be powered by 110v or 220v from

which it generates the 24v AC for the solenoids.
Flushing cycles may be triggered either by time or by the embedded electronic DP sensor

reaching the set point, or by a dry contact signal from an external DP sensor.

Endless looping problems can be eliminated by detecting repeated consecutive cycles

passing beyond a predefined limit.

The unit can optionally handle a Pressure-Sustaining / Main valve, and an Alarm output.
The unit is equipped with a customized LCD display and key board.
The unit counts separately the number of flushing cycles triggered by DP, by time and

manually.

How to program the controller

The controller is equipped with an LCD display and 4 keys as displayed below. When the unit is left
untouched for a minute the display is switched off and the only life signal is given by a beep sound that
can be heard every 20 seconds. Holding down any of the keys for a few seconds will bring the screen
back to life.

MANUAL

The screen consists of several fields, some of them are editable and some of them are not. For
inserting EDIT MODE the ENTER key has to be pushed. The EDIT MODE is indicated by blinking of
the characters at the currently editable field. Each time the ENTER key is pushed again, the next
editable field becomes under focus and starts blinking. While in EDIT MODE the “+” and “-“ keys can
be used for changing the value under focus. Pushing the ENTER key again will set the selected value
to the current field and move the focus to the next editable field which will start blinking. Once entering
this process of passing through the editable fields, the user has no way back but by pushing the
ENTER key repeatedly, he passes through the chain of editable fields until arriving back to the FLUSH
TIME field, meeting no more blinking fields.

Notice that before the first use of the unit, it may be necessary to pass through
the configuration process prior to defining the flushing program in order to
adjust the features of controller to the specific application. The configuration
process is described below.

The chain of editable fields

Following is the chain of editable fields. The existence of the DP SET-POINT field depends on whether
the system contains a built-in electronic DP or not.

The Actual DP value.
Available only when
the built in electronic
DP is used

The DP Set-Point.
Available only when

DP is used

The desired flushing
time per station

The desired flushing
mode. Contains either the
flushing interval or the

letters “dp” when the
