Features
The “FILTRON 1-10” is a modular backflushing controller for automatic filters of 1 to 10
stations.
Models come in both DC and AC variants.
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 solenoid 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.

The screen consists of several fields, some of them are editable and some of them are
not. For inserting EDIT MODE, push the ENTER key.
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.

At this field the user defines the pressure difference between the filter’s inlet and outlet
that when reached, a flushing cycle will take place. The DP set-point field will disappear if
there is no Electronic DP connected. In this case the Digital DP input can be used.
Up to version 1.02 of the Filtron 1-10, a nonzero value Set-point would have caused the
controller to ignore the Digital DP input completely, but a zero Set-point would make the
Digital DP effective and cause the Electronic DP to be ignored.
Starting from version 1.03 a change was made so that a nonzero Set-point does no longer
cause the Digital DP input to be ignored, but instead a closed contact Digital DP input will
cause the unit to keep on executing flushing cycles as long as the contact remains closed,
ignoring the looping limit. When the DP contact reopens, the flushing stops right away
without completing the running flushing cycle.
Starting from version 1.05 everything explained above for version 1.03 holds, but instead
of executing complete flushing cycles while the Digital DP input is closed, it will be only
valve No. 1 which will remain open as long as the contact is closed.
Starting from version 1.03 if there is no Analog DP connected or when the set-point equals
zero the unit refers to the Digital DP in the normal way, namely when the contact of the
Digital DP is constantly closed it will execute consecutive flushing cycles until reaching the
Looping Limit and then declare an endless Looping problem.
When the pressure is expressed in BAR the range of values is 0.1 – 2.0 BAR.
When the pressure is expressed in PSI the range of values is 1- 30 PSI. The closed Digital DP
contact will be indicated by the symbol :

The Flush Mode
OFF-By time - No flushing will take place.
DP- Flushing will be triggered by DP only.
The Flush Mode defines how the flushing cycles is triggered. The selectable options are as
follows:
In this case, the flushing cycles will be repeated in a selected interval or will be triggered by
the DP signal depending on which happens first. No matter how the flushing cycle started,
the interval to the next cycle will start to be measured again after each ending of flushing
sequence. The selectable intervals are as follows:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes
2, 3, 4, 5, 6, 8, 12, 18, 24, 72, 120 hours
If the “+” and “-“ keys are pressed and held down simultaneously the “Flush Mode”
field will show the left time until next cycle, alternately hours and minutes.
The Accumulations
The unit accumulates and displays the number of flushing cycles caused by DP, by time, or
manually At each of the accumulation fields, the “+” or “-“ keys may be used for clearing
the accumulated value.

The Configuration
Backflush valves will be allocated starting from output 1 and up.
The last backflush valve can be canceled and then its allocated output will be left
unused.
Three additional output devices can be included in the configuration: Alarm output,
Delay-Valve, and Main-Valve. Their location on the terminal board will be right after
the last backflush valve, first the Alarm output next the Delay valve, and then the Main
valve.
In order to enter into the configuration process press and hold down the ENTER key for at
least 3 seconds. The unit will detect how many “plug-in” boards (each of 2 outputs) are
used in the particular case. How the outputs will be allocated depends on the definitions
made during the configuration process described below. The following rules apply:
1.
2.
3.
Example:
Assuming there are 3 “plug-in” boards, this makes 6 outputs for use. If there are no Alarm-
output, no Delay-Valve and no Main-Valve, all the 6 outputs will be allocated for backflush
valves. If additionally a Main-Valve is defined, the first 5 outputs will be allocated for
backflush valves and output No 6 for the Main-Valve.
Output No 5 (of the last backflush valve) can be canceled and left unused. If additionally a
Delay-Valve is defined it will be allocated to output 5 right before the Main valve, leaving
the first 4 outputs for backflush valves, and once again output No 4 (of the last backflush
valve) can be canceled and left unused.
If additionally an Alarm-output is defined it will be allocated before the Delay-Valve
leaving only the first 3 outputs for backflush valves. No 3 can again be canceled.

During the configuration process, the following features are defined:
Main Valve (sustaining valve) - Yes/ No. When the answer is “Yes” the Pre Dwell delay can
be set.
The Pre Dwell delay is measured between the command to the Main Valve and the
command to Station No. 1.
The selectable steps are:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 sec
1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 min
Dwell Time - The delay between stations – can be set to 5, 10, 15, 20, 25, 30, 35, 40, 45, 50,
55, or 60 sec.
DP delay - The delay during which the DP sensor reading is expected to remain stable
before reaction – 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 sec.
Looping limit - The number of consecutive flushing cycles triggered by the DP sensor
before deciding that there is an endless looping problem. The options are: 1-10 or “no”
which means ignoring the looping problem.
Alarm - Yes/No – allocating one output for alarm activation.
Delay Valve - Yes/No – allocating an output for Delay Valve activation.
View Outputs - This is a special mode that enables passing through the list of outputs to see
how each output was allocated. Use the + key to change the “no” into “yes” and confirm by
“Enter”, then keep using the + key to pass through the list. At the bottom left corner the
ordinal number of the output is displayed and its allocated function appears in large letters
at the center of the screen. Notice that the number of possible outputs that can be used is
always an even number since it results from the number of “plug in” boards (each of 2
outputs) included. However if the number of outputs needed is not an even number, then
the last valve allocated for flushing may be canceled by use of the manual operations key.

Pressure Units - Deciding about the units to be used for pressure measurement. Selecting
between BAR or PSI .
Calibration - Zero calibration of the built in electronic DP sensor. While the sensor ports
are disconnected select Calibration = Yes.
Version display - The last screen of the configuration supplies information about the
software version of the controller. the version consists of 4 digits like the following: 00

Handling Endless Looping Problems
As explained above, endless looping problem will be declared when the number of
consecutive flushing cycles triggered by the DP sensor exceeds the “Looping limit” defined
during configuration. The fact that endless looping problem was detected will be indicated
on the display and will cause the activation of the Alarm output, additionally, the DP
indication will no longer be considered as a trigger for flushing. The following flushing
cycles will be triggered by the interval count down only. The problem will be considered as
solved when the constant indication of the DP sensor will be removed.
Handling Low Pressure
When a closed contact indication is received at the low pressure input of the controller, the
symbol will start to appear blinking at the display.
All activities will stop including the countdown to the next flushing cycle. If the low pressure
happened while a flushing sequence was in progress, when the low pressure condition
terminates the flushing sequence will start from the beginning rather than continue from
the stop point.

Connecting the DP sensor to the filter system
The DP sensor is connected to the filter system by 2 command tubes, the one which comes
from the filter inlet (High pressure) will be connected to the red point, and the one that
comes from the outlet (Lower pressure) will go to the black point. It is important to put a
small filter of 120 mesh (not supplied) between the red point and the high pressure
connection point.
Low Battery
The unit has two levels of low battery indication. At the first level when the battery voltage
drops to the first level, the sign will start to appear at the screen. When the battery
voltage drops further and reaches the second level, all outputs will shut down, the screen
will be cleared leaving only the low battery icon.
