Extension options for your SENECT control
All the expansion options listed here are not included in the scope of delivery of your
SENECT Control unit. For a detailed list and more information about expansion options,
please visit
. Some examples of extensions are
presented here. Please refer to the respective instructions for use of the extensions.
Connection of sensors
Your SENECT Control unit can measure many water quality parameters by connecting
SENECT sensors. If an actuator is switched in addition to the respective sensor, the
respective parameter can be controlled. A typical application is the control of dissolved
oxygen. For this purpose, the oxygen sensor O2S (Art. No.: 2100) is used, for example with
a solenoid valve O2 M7, to introduce gaseous oxygen into the fish breeding tanks through
outflow valves. Please note that only level sensors and a temperature sensor can be
connected to the FILTER|CONTROL.
Connection of a magnetic valve for water replenishment
In order to keep the water level in the pond or basin constant and thus also to operate
filters hydraulically in an optimal way, the SENECT control unit can be used in combination
with a level probe (PS-300-MA or EPS-250-MA) in the pond / basin / prechamber and a
SENECT solenoid valve M12 (MVW-M12-SC). To do this, connect the level probe to plug
SENSOR 2 and the magnetic valve to plug OUT 2.
Connection of further level probes
In order to increase the reliability of the drum filter system and to take into account water
level changes in the system, we recommend the use of a second level probe / screw-in
level sensor in the filter.
If the first level sensor is located in the rear filter chamber, the second level sensor must
be installed in the prechamber. If the first sensor is in the prechamber, the second level
sensor must be installed in the rear chamber. By using two level sensors, the water level
difference between the two sensors is used to detect the degree of contamination of the
filter fabric. This makes the system less susceptible to water level fluctuations of the pond
system and reduces the water consumption of the system.
