2. Sicherheitshinweise
Bitte lesen Sie vor der Installation und Inbetriebnahme alle Sicherheitshinweise sorgfältig durch. Die Nichtbeachtung dieser Hinweise kann zu Stromschlag, Brand oder schweren Verletzungen führen.
- Elektrische Gefahr: Vor jeglichen Installations-, Wartungs- oder Fehlersucharbeiten muss die Stromversorgung unterbrochen sein.
- Bandtage Kompatibilität: Überprüfen Sie, ob die Stromversorgungsspannungtage matches the controller's specifications (220V/110V AC).
- Richtige Erdung: Always connect the device to a properly grounded outlet.
- Wassereinwirkung: Do not immerse the controller unit in water. The controller unit is designed to be mounted above the water level.
- Qualifiziertes Personal: Installation and electrical connections should be performed by qualified personnel if you are unsure.
- Umgebungsbedingungen: Do not operate the device in explosive atmospheres or where flammable liquids or gases are present.
3. Produktmerkmale

- Mehrere Betriebsmodi: Supports Drain Mode (for emptying) and Water Mode (for filling).
- LED-Anzeigen: Visual feedback for power, load status, and alarm conditions.
- Überlastschutz: Integrated protection for connected pumps.
- Mute-Funktion: Allows silencing of the alarm.
- Breite Anwendung: Suitable for sewage pits, fish tanks, water tanks, and other water management systems.

4. Einrichtung und Installation
Proper installation is crucial for the reliable operation of the controller.
4.1 Controller-Montage
The controller unit should be mounted in a dry location, above the maximum water level, and within reach of a grounded power outlet.
- Schraubmontage: Use appropriate screws and anchors to secure the controller to a wall or stable surface through the mounting tabs.
- Saugnapfmontage: For temporary or non-permanent installations, a suction cup can be used to attach the controller to a smooth, clean surface.

Abbildung 4.1: Controller Installation Methods.
4.2 Sensor Installation and Adjustment
The dual sensors detect the high and low water levels. Their position determines the operating range of your pump.
- Sensorplatzierung: Position the sensors vertically in the water, ensuring they are securely fastened and will not move. The lower sensor defines the 'low' water level, and the upper sensor defines the 'high' water level.
- Einstellbarer Bereich: The sensors can be adjusted along their cables to set the desired water level range, from 1/2 inch to 20 inches apart. Ensure both sensors are submerged at the desired 'on' level and the lower sensor is exposed at the desired 'off' level for drain mode, or vice versa for water mode.
- Kabelmanagement: Route sensor cables to prevent entanglement or damage.

4.3 Elektrischer Anschluss
- Netzstecker: Plug the controller's power cord into a grounded 220V or 110V AC outlet.
- Pumpenanschluss: Plug your sump pump or other load device into the outlet on the front of the controller. Ensure the pump's power requirements do not exceed the controller's output capacity (15A, up to 2HP).

5. Bedienungsanleitung
The controller features a simple interface for selecting operating modes and managing alarms.

Abbildung 5.1: Systemsteuerung überview.
5.1 Modusauswahl
Use the 'Drain' and 'Water' buttons to select the desired operating mode:
- Ablassmodus: (LED indicator 'Drain' illuminates) In this mode, the controller activates the pump when the water level reaches the upper (high) sensor and deactivates it when the water level drops below the lower (low) sensor. This mode is typically used for emptying sewage pits or sumps.
- Wassermodus: (LED indicator 'Water' illuminates) In this mode, the controller activates the pump when the water level drops below the lower (low) sensor and deactivates it when the water level reaches the upper (high) sensor. This mode is typically used for replenishing water in fish tanks or water tanks.
5.2 Power and Operation Switch
The main switch controls the power and operational state of the connected load:
- WAGEN: (LED indicator 'AUTO' illuminates) The controller operates automatically based on the selected mode (Drain or Water) and sensor readings.
- AUS: (LED indicator 'OFF' illuminates) The connected pump is turned off, regardless of water levels.
- AUF: (LED indicator 'ON' illuminates) The connected pump is continuously turned on, regardless of water levels. Use this for manual override or continuous operation.
5.3 Mute-Funktion
Press the 'Mute' button to silence any active alarms. The 'DisAlarm' LED will illuminate when the alarm is muted.

6. Wartung
Regular maintenance ensures the longevity and reliable operation of your Ortis controller.
- Sensorreinigung: Periodically inspect and clean the stainless steel sensors to remove any buildup of debris, algae, or mineral deposits that could affect their accuracy. Disconnect power before cleaning.
- Kabelinspektion: Check all cables and connections for signs of wear, damage, or corrosion. Replace any damaged components immediately.
- Steuereinheit: Keep the controller unit clean and dry. Avoid exposing it to direct sunlight or extreme temperatures.
- Testbetrieb: Periodically test the controller's operation by manually raising or lowering water levels to ensure the pump activates and deactivates as expected in the selected mode.
