Page 10: Installation
Installation Choose a place for the electronic interface (electronic unit protected by black silicone casing) which is clean, dry and protected from direct sunlight. Ensure that all cables are placed safely and all regulations are fulfilled. Mount the sensor so that the sensor head is permanently submerged. This can be achieved, for example, by attaching it using suction cups or, if the water level fluctuates greatly, by attaching it to a float. - Page 11 Important Note: Sensor EPS The Water level sensor EPS must not be submerged. Use the submersible water level probe PS for this purpose.
-
Page 12: Getting Started
Connect the sensor cable with a control unit (plug „SENSOR“). The control unit recognizes the sensor and starts the measurements. The menu may differ depending on the software version used. Updates to these operating instructions can be found at www.senect.de. -

15 cm is required. Connect the connection cable to your control unit at one of the sensor slots marked in blue. The SENECT control units automatically detect the water level sensor and start operation. - Page 14 Figure 4: The locations of the water level probe when a drum filter is to be controlled. Please note, that in the gravity mode, the PS is in the filter chamber, while in pumped mode, the PS is installed in...
- Page 15 The cleaning of drum or belt filters can be triggered depending on the contamination by measuring the water level. A distinction must be made here as to whether a rise or fall in water level should trigger cleaning. In gravity mode (see Figure 4 ), the probe is mounted in the filter chamber and a drop in the water level triggers cleaning.
- Page 16 Water level probe – Refilling water level Select "Refill sensor" as the position and place the probe in your pond or basin. Set the water level to "0 cm" with "Reference sensor". With the position "Refill sensor" the sensor value is additionally displayed in the app as "Pond" in the filter sensor values field. You can move the "0 cm"...

Connect the supplied connection cable to the sensor and your control unit at one of the sensor slots marked in blue. The SENECT control units automatically detect the sensor and start operation. - Page 18 Application example The pressure sensor EDS can be used to monitor the line pressure of the ventilation line (oxygen or compressed air). If there is a fault in this supply line (tank empty, generator defective, leakage), the EDS can trigger an alarm if the pressure falls below the set lower threshold value.

Connect the blue marked plug of the sensor with a sensor input port (also blue marked) of your control unit. The SENECT control units recognize the sensor itself and start automatically the measurements. Take into account that the measurement interval is set to 30 s to elongate the lifetime of the sensing cap. - Page 20 Recalibration intervals Recalibration of the sensor is regularly recommended every 6 months. To determine if a calibration is necessary, hold the sensor in air (preferably with 100% humidity) for a few minutes. If the sensor shows about 100% oxygen saturation (usually this value is just below 100% due to insufficient humidity), no calibration of the upper calibration point is necessary.
- Page 21 Salinity / Conductivity correction : If no conductivity sensor is connected, fresh water with a salinity of 0 PSU is assumed as the medium and no correction takes place with regard to electrical conductivity or salinity. However, you can specify an electrical conductivity (which is used as a measure of salinity) in the menu under "Sensor / O2S / Salinity correction"...
- Page 22 The SENECT control units measure the air pressure and use it to correct the calibration and the measured values. Sensor error If the sensor or the membrane is damaged and it is no longer possible to read out reliably measured values, an error code is given. You can send this information as well as further background information regarding the sensor behavior directly by email to SENECT GmbH &...

Connect the blue marked plug of the cable with your control unit at one of the sensor input ports. Your SENECT control unit will automatically recognize the sensor and starts the measurement. Please refer to the instructions in the operating manual of the control unit. - Page 24 To increase the service life, the sensor can be mounted so that the upper part of the sensor and the cable are not submerged. This can be achieved either by attaching it by means of suction cups or, in the case of highly fluctuating water levels, by mounting it on a float. Alternatively, the electrode can also be installed in the pipe system (e.g.
- Page 25 The concentration of dissolved carbon dioxide can be determined indirectly via the parameters alkalinity, temperature and the pH value. The SENECT control units can automatically calculate the CO2 concentration if the alkalinity is entered manually (e.g. determined via photometric measurement) and the temperature is known.
- Page 26 Notes regarding the measurement of the oxidation -reduction potential Each SENECT ORP sensor delivered has been tested and calibrated for proper functioning by our quality assurance staff. Despite the high quality requirements, the measured value may be influenced by the measuring principle and the properties of the medium.

Connect the blue marked plug of the cable with your control unit at one of the blue outlined sensor input ports. Your SENECT control unit will automatically recognize the sensor and start the measurement. Please refer to the instructions in the operating manual of the control unit. - Page 28 Additional information about the unit of salinity The term salinity refers to the salt content of liquids, mostly water. Its typical unit is „mass of salt per kg of water“ (g / kg). The unit ppt (parts per thousands) is also used and refers to the mass, which makes it interchangeable with g / kg (e.g.

Choose in the menu of your control unit the pH sensor (Sensors / Sx: pH) and select “Sensor Calibration / pH / Calibration Point 1“. Select the pH value of your calibration solution (here: pH = 4.00) and move the electrode gently until the displayed raw signal value (in digits) is nearly constant.
- Page 32 Redox Sensor XT1 The calibration of the ORP sensor is a 2-point calibration, where the first calibration point (0 mV) is determined with the supplied BNC calibration plug and the second calibration point is determined with the +475 mV test solution. The calibration is only performed initially and after an electrode exchange.
- Page 33 Rinse the electrode again and immerse it in the second (higher) calibration solution and repeat steps 2 to 4. If the calibration is correct, save it in the menu under "Save calibration". Your SENECT ORP Sensor XT1 is now ready to be used.
- Page 34 Oxygen-Sensor O2S Place the sensor for several minutes at humid (100% water vapour saturated) air and ensure, that there are no water drops on the membrane. Select in the menu „Sensors“ the oxygen sensor (O2S) and choose „Sensor calibration/ O2 % a.s.“.
