General Security Notes
The SENECT® FILTER|CONTROL is an electronic control unit developed for controlling drum
and belt filters.
Since it is an electric product the common prerequisites for a safe instrument usage
must be fulfilled. The device must be operatated with 230 V AC (~50 Hz). Ensure
that all cables are installed safely so that no obstacles for persons are built and all.
Mount all cables and electric devices protected against direct environmental
impacts like overheating by direct sunlight and water. Even if the product is
protected against spray water, the product´s lifetime will be elongated, if it is
mounted on a protected place.
For many applications a ground fault circuit interruper (interrupting current <= 30 mA) is
required by law. Inform yourself about the valid legislation. If the mains plug cable is damaged,
only the producer or a qualified person designated by the producer is allowed to repair the
damage.

Intended use
5
The operating temperature of the device must be between 0°C and +40°C. It is not allowed to
modify the FILTER|CONTROL, to open the housing or to insert anything into the housing.
If the power cable is damaged, it must be replaced by the producer or a qualified person
designated by the producer to avoid potential dangers.
The device is designed to be operated by professional users. It can be also operated by
children over the age of 8 years and persons with limited physical, sensorial or cognitive ability,
if they are supervised, trained in the operation of the device, able to operate the device safely
and if they understand potential risks resulting from the operation. It is for children or persons
with limited physical, sensorial or cognitive ability not allowed to perform any maintenance
works.
Please store this manual. We suggest the storage a copy of the manual in the vicinity of the
drum filter.
Technical and optical changes of this manual are subject to alterations.
Warning: Before doing any maintenance work switch off all electric devices or unplug
the mains plug.
Intended use
The SENECT® FILTER|CONTROL is an electronic control unit developed for
controlling drum and belt filter in industrial applications. It can be combined with
maximal two water level sensors (SENECT PS-300-MA or EPS-250-MA), one filter
case switch, one solenoid valve (MVW-M12-SC) and one further actuator (e.g. alarm lamp VIS-
LED).
On the three 230 V AC plugs, one spray pump, one UVC lamp or a 230 V AC filter motor and
one circulation pump can be connected.
The direct control of drum or belt filters is only possible for filter with a 24 V DC filter
motor with max. 5 A (FC-A1-333-150) or 10 A (FC-A1-333-300) or with a 230 V AC
filter motor. The spray pump must be operated with 230 V AC with a maximal
current of 8 A.
General theory of operation
Drum and belt filter (terms were used interchangeably) remove suspended particles in
aqueous solutions. Therefore, the water flows through a filter mesh and the particles stick to
the mesh. The FILTER|CONTROL can detect if the filter mesh is clogged by measuring the water
level in front of or behind the filter (only with the optional PS-300-MA or EPS-250-MA). If the

Getting started
6
filter mesh is clogged, the FILTER|CONTROL starts the filter motor so that the drum starts to
rotate or the belt starts to move and the spray pump will be activated. The filter mesh will be
flushed and all dirt particles will be washed to the outlet.
Alternatively, if the is no water level sensor connected to the FILTER|CONTROL, a time
controlled operation of the filter is also possible.
With the FILTER|CONTROL, many parameters can be set by the user so that many different
types of filter can be operated with the FILTER|CONTROL.
With its 230 V AC circulation pump plug, one pump with a maximum power of 900 W can be
connected and is therefore implemented in the control algorithm. This enables for example
the emergency switch-off of this pump in case of water level below the alarming threshold. If
you want to use a pump with a power of over 900 W, the optional Power Switch (PWS-24230-
SC) can be used.
Besides the operation of the filter, the FILTER|CONTROL can regulate the water level (PS-300-MA or
EPS-250-MA plus solenoid valve MVW-M12-SC necessary) by measuring the water level and
activating a solenoid valve.

Plug the 230 V power plug of the FILTER|CONTROL in a spray water protected plug (IPx4 or
higher) but do not switch FILTER|CONTROL on yet.
1.) Water level sensor installation
If you do not have a water level sensor, please continue with 2.).
The optimal location of the water level sensor (PS-300-MA or EPS-250-MA) is where
a control over the proper functioning of the circulation pump is. In a gravity system,
this location is usually behind the filter while in pumped systems, this is typically
before the filter or in the pre-chamber of the filter.
Please do not insert the water level sensor deeper than 2.5 m and ensure that it is well fixed
and at a place with low direct currents. Read also the instructions of the level sensor manual.
Fig. 2: Sensor and actuator ports of the FILTER|CONTROL.

Getting started

Connect the water level probe PS for the filter control with SENSOR 1 (see Fig. 2). If you are
using a second water level probe PS, connect the 2nd probe with SENSOR 2.
If you are using two water level sensors EPS-250-MA, connect the sensor in the filter chamber
with SENSOR 1 and the sensor in the pre chamber with SENSOR 2 (for water refill).
2.) Case switch
If your filter is equipped with a case or cover proximity switch, you can connect it to SENSOR 3.
If you do not have a suitable plug at your switch, you can order the proper plug from SENECT
or your dealer.
The function of the case switch is to switch off the drum motor and a connected UVC lamp
(which are often located inside the drum filter), when the cover is opened (mode: drum filter).
In the mode “belt filter” is selected, then only the UVC lamp is switched off.
Please consider that the case or cover switch does not fulfil all requirements to be an
emergency stop switch according to EN ISO 13850:2015-10.
3.) Filter motor
24 V DC Filter motors:
Ensure that the filter motor is correctly installed at your filter and check in the technical
documentation, if the motor can be operated with 24 V DC (max. current 5 or 10 A). If yes,
you can connect the motor with the delivered cable (polarity: red = +, black = -). Connect the
motor cable plug to OUT 3 (motor).
Fig. 3: View at the lower side of the FILTER|CONTROL.

230 V AC Filter motors:
If your filter is equipped with a 230 V AC motor, connect its plug at the 230 V plug UVC /
MOTOR. Please consider that only motors with a power of max. 500 W can be connected
directly. Motors with a higher power consumption can be connected via the optional Power
Switch 24-230.
Note here, that all functions where the motor speed is controlled by the FILTER|CONTROL do
not work, because there is just an on / off switching of the filter motor possible. These
functions are:
Intensive cleaning programme
Soft motor start
High-pressure cleaning mode
If you want to use these functions with AC motors, you need a variable frequency drive to
control the motor speed.
230 V / 400 V AC Filter motors connected via variable frequency drive (VFD):
For changing the rotation speed of AC filter motors, which allows to use all functions which
change the motor speed, a variable frequency drive between the FILTER|CONTROL and the
filter motor is necessary.
SENECT offers fully configurated, parametrized and wired VFDs. The green labelled actuator
cable from the VFD must be connected to one the actuator output ports, e.g. OUT 1.
Note: Select the function “filter motor” for the corresponding actuator output port
(here OUT 1) and select the additional function “variable frequency drive”.

4.) Connecting the spray and circulation pump
If the pumps are correctly installed, arrange all cables safely to your FILTER|CONTROL. Check
on the data sheets of your pumps, if they fit to the specifications of the FILTER|CONTROL
(spray pump: 230 V AC, max. 1800 W, circulation pump: 230 V AC, max. 900 W). Plug the spray
pump connector into the plug „SPRAY PUMP“ and the connector of the circulation pump to
the plug „CIRULATION PUMP“ (see Fig. 3).
To operate a drum or beltfilter correctly, it is necessary to connect the filter motor
and spray pump according to the specifications of the filter producer.
Every drum or belt filter consumes water. Therefore, it is absolutely necessary
that the lost water is refilled. Ensure that either the water is replenished
automatically or if manually, that the water level in your tanks or ponds is
constant.

Filter settings
Here you can configure all relevant settings for the filter operation.
Filter Mode
Select here, if you are using your filter in a gravity or pumped system. The selection here
means that the filters backwashing is triggered by an decrease of the water level (typically
for gravity mode, where the sensor is installed behind the filter) or by an increase (when
the sensor is installed before the filter).
Operating Mode
Without a water level sensor, the filter is operated time-controlled. In this menu point, you
can choose the operation mode. „Automatic mode“ means that based on the clogging of
the filter mesh, indicated by the measurements of the water level sensor, the cleaning is
initiated. In the „Time-controlled mode“, the filter is cleaned in regular time intervals. The
“High-Press. Cleaner” mode lets the filter motor run continuously, but slow without
activating the spray pump. This mode is handy, when the filter mesh is cleaned manually
with a high-pressure cleaner.

Filter settings
19
Extras
Here you can select the activation of extra functions.
1. Dynamic|Mode:
The Dynamic|Mode is a special algorithm which leads to a more stable clogging-induced
control of the backwashing. With this mode, the backwash water level is continuously
corrected for changes in the water level. Please note, that the backwashing is then not at
exactly the specified backwash water level. Instead it starts when the “corrected”
backwash level is reached.
2. Eco|Mode
With the Eco-Mode you can decrease the water consumption of your filter. When the water
level sensor initiates the cleaning, only the filter motor is activated for a short time to bring
the until then unused filter mesh into the water. By monitoring the water level, the
FILTER|CONTROL will decide when the next full cleaning is necessary.
3. Cover Sw. DF
If the cover switch is defined as “Cover Sw. DF” where DF stands for drum filter, the
backwashing will be stopped, if the cover is opened. Additionally, when the 230 V plug 2 is
defined as “UVC lamp”, it will be also switched off immediately.
4. Cover Sw. EBF
In case the cover switch is set to EBF, which means “Endlosbandfilter” or continuous belt
filter, a backwashing will not be interrupted when the cover is opened. The UVC on 230 V
plug 2 however will be switched off.
Water level
All water level related parameters are system-specific. In this menu item, you can configure
the cleaning-related water level settings.
Flush Level
The flush level is the water level threshold, under (gravity system) or over (pumped system)
which the cleaning is initiated. It is always displayed positive as a difference.
Dry run Protection
The Dry run Protection level is the water level at which the circulation pump is deactivated
and the system stopped. If the water level is below this level, the FILTER|CONTROL tries
several times to reactivate the filter. Only if the operation can be safely continued, the
FILTER|CONTROL goes back into the normal operation mode.
You will see this as a message in the display. The symbol “Pause” will also appear. To restart
the operation manually, press “STOP”.

Filter settings
20
Backwash Parameter
Here you can set all relevant parameters for the filter cleaning.
Backwash Duration
The backwash duration defines the time of one cleaning cycle. Choose the flush time so
that the drum is rotated at least one time completely.
Pre-flushing time
With the pre-flushing time, you can define how long the spray pump is activated before the
filter motor starts.
Post-flushing time
To discharge also the last rest of particles from the flush tray, you can set with the post-
flushing time the duration, how long the spray pump should stay activated after the filter
motor stops.
Cleaning pause
The cleaning pause defines the minimal temporal distance between two filter cleaning
events. This break prevents from water loss associated from too man cleaning events. But
in case the water level drops further towards the emergency level, the filter flushes despite
there is a cleaning pause. This function disables the cleaning pause in situations, when
urgent cleaning is necessary.
Forced Clean. Cycle
Here, you can specify how often the filter should be backwashed even when the sensor
does not detect the necessity of backwashing. This means that you can set here the
maximum time where the filer is not flushed.
