Every type of SENECT sensor can be connected to the universal sensor input ports (e.g. the
oxygen sensor O2S, the pH sensor XR-1 or the water level probe PS). The
AQUACULTURE|CONTROL measures then the signal of the connected sensors, saves the
measurements internally (up to max. 3 months) and can control output ports depending on
the sensor readings or send alarm message, if the control unit is connected to the internet.
At its actuator output ports, 24 V DC actuators like valves or fish feeders can be connected
directly. Also actuators, which can be controlled via 4-20 mA or 0-10 V control signals can be
controlled directly. Actuators with 230 V AC can be switched with the actuator ports by using
the optional PowerSwitch SC24-230 or can be controlled directly, when they are connected to
one of the three 230 V AC output ports at the bottom side of the device. Please consider
always the max. allowed power consumption of actuators.
The AQUACULTURE|CONTROL can also be used to control drum or belt filters. Pleas consider
here:
The direct control of drum or belt filters is only possible for filter with a 24 V DC filter
motor with max. 5 A (AQC-A1-xx3-150) or 10 A (AQC-A1-xx3-300) 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. For enabling all functions which need to adjust the motor speed of the filter
(e.g. intensive cleaning), 230 V or 400 V filter motors must be controlled via a variable
frequency drive connected to one of the actuator output ports (see Fig. 5).

Using the AQUACULTURE|CONTROL to switch outputs as a function
of sensor measurements
Which sensors, which actuators and how the cables are conneced depend strongly on your
application. In general, you can follow these steps:
1. Mount sensors and actuator at their location.
2. Place and lay the cables safely to the AQUACULTURE|CONTROL, remove the
protection cap from the sensor input port and connect the sensor plug to the blue
marked „SENSOR“ input.
3. Switch on the AQUACULTURE|CONTROL and set the desired settings. To switch the
output ports, you have to assign a function to the selected output port.

Application example: Oxygen control
In this example, the oxygen sensor O2S is connected to SENSOR 1 and the „normally opened“
solenoid valve (Type: MVO-M7-SC, Art. No.: 3020) is plugged into actuator plug OUT 1.
(„Normally open“ is selected here, that in case of a power shutdown the valve opens
automatically and the fish still get oxygen.)
The desired oxygen level should be over 95% and if 100% are reached, the addition of oxygen
shall be stopped. Go to the menu (MENU / Output Ports / Plug 1) and set:
Function: Sensor Control –a new submenu appears (when you go back in the
menu)
In the submenu „Sensor Control“ set:
oControl Parameter: O2 % a.s.
oSensor Plug: 1
oStart value: 95%
oStop value: 100%
oMax. Duration: 00:00:00
oBreak Time: 00:00
In the submenu „Output signal“ set:
oPolarity: Low Active (the output is switched off, when the O2
concentration falls below 95% so that the [normally open] valve opens)
Now, all the settings are done and you can test the system, e.g. dipping the O2S sensor in
0-%-oxygen solution.

4. Optional: Connect the AQUACULTURE|CONTROL with your WLAN network (see
chapter: WLAN).
5. Check the function of your control settings. Hint: You can easily check the actuator by
selecting the function „Constant on“.
Now, your system is ready for useage.
Controlling the drum filter with the AQUACULTURE|CONTROL
When you want to control a drum or belt filter with the AQUACULTURE|CONTROL follow the
steps below:
1.) Water level sensor installation
If you do not have a water level sensor, please continue with 2.).
Mount the water level probe or sensor at its the optimal location. The optimal
location of the water level sensor (PS-300-MA or EPS-250-MA) is where the water
level responds to the clogging of the filter and 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 location with low direct currents. Read also the instructions of the water level sensor
manual.
Connect the water level sensor cable to the AQUACULTURE|CONTROL (e.g.) with SENSOR 1
(see Fig. 2). If you are using a second water level sensor, connect the 2nd probe with SENSOR 2.
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 optional available motor cable (Art. No.: 3400, polarity:
red = +, black = -). Connect the motor cable plug to the high-power actuator output port
OUT 3.
230 V AC Filter motors:
If your filter is equipped with a 230 V AC motor, connect its plug with the main plug 2 (230 V
OUT 2). Please consider that only motors with a power of max. 500 W can be connected
directly here. Motors with a higher power consumption can be connected to the other two
230 V PLUG 1 or 230 V PLUG 3, in case these are not needed for other consumers like a spray
pump or can be connected to actuator output ports via the optional Power Switch 24-230 (Art.
No.: 3100).
Note here, that all functions where the motor speed is controlled by the
AQUACULTURE|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 AQUACULTURE |CONTROL
and the filter motor is necessary.
SENECT offers fully 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.

Fig. 5: Connecting a drum filter via a variable frequency drive.
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
AQUACULTURE|CONTROL. Check on the data sheets of your pumps, if they fit to the
specifications of the AQUACULTURE|CONTROL (230 V OUT 1: 230 V AC, max. 1800 W, 230 V
OUT 3: 230 V AC, max. 900 W). Plug the spray pump connector into the plug „230 V OUT 1“
and the connector of the circulation pump to the plug „230 V OUT 3“ (see ).
To operate a drum or belt filter 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.

Getting started
15
STARTING THE SYSTEM
Switch the AQUACULTURE|CONTROL on with the ON/OFF Switch at the bottom (Fig. 3).
By pressing the button MENU, you can configure all necessary settings. With the cursor
buttons and , you can choose the desired menu item and to confirm your selection, press
OK. The button BACK brings you alway one hierachical level down, while HOME displays the
normal screen and exits the menu.
If your filter is used in a pumped system, select in the Filter Settings as Filter Mode „Pumped
System“. If you are operating the filter in gravity mode, select “Gravity System”.
If you are using a 230 V AC filter motor connected to a 230 V main plug, select in the menu at
230 V Plug / 230 V Plu X the function „Filter Motor”. If you are using a 230 V AC filter motor
connected via a variable frequency drive to an actuator output port, select in the menu at
Fig. 6 Sketch showing the general two hydraulic systems in which drum filter are operated.

Getting started

Output ports / Plug X the function „Filter Motor”and the additional function “Var. Frequency
Dri”.
To assign a function to the water level sensor(s), select in the menu Sensors / S X / Position
to the location where the sensor is mounted. Is it in front of the drum, select “Pre-chamber”,
and is it mounted behind the drum, select “Filter-chamber”. The Pre-chamber defined sensor
starts flushing when the water level rises above the flush level, while the definition Filter-
chamber initiates the cleaning, when the water level falls below the flush level.
Check and eventually select the proper type of water level sensor connected to your
AQUACULTURE|CONTROL. If you are using the water level probe PS, select Sensors / S X /
Sensor Type the type: „PS-300-MA” while if you use the water level sensor EPS, select „EPS-
250-MA“.
If you have connected your circulation pump to the AQUACULTURE|CONTROL, assign the
function “Circulation pump” to the corresponding 230 V plug. You can now switch off (and
on) your circulation pump by pressing the button „STOP“.
After connecting your spray / jet / backwash pump to the AQUACULTURE|CONTROL, assign
the function “Spray pump” to the corresponding 230 V plug. If you have it connected via an
PowerSwitch or VFD at one of the actuator output ports, assign the function “Spray pump” to
this port.
Clean the filter by pressing the button „CLEAN FILTER“. After the cleaning process, check the
water level in your system. If the water level is correct, you have to set the water level
sensor(s) to zero (referencing). Go therefore in the menu to Sensors / S X / Sensor Referencing
and confirm with yes. This sets the relative water level to 0 cm (the absolute water level is
always the actual water level measured by the probe, while the relative water level refers to
this set zero condition).
Now, your system is ready for operation.
To achieve the most efficient operation, you have to configure all other filter-related settings
so that they fit to your filter, for example the cleaning duration, etc. You´ll find more
information in the chapter “Operation”.
