Diagnosis in case of error

If errors occur, you can use this guide to isolate the error. Please check the following steps carefully.

New: Troubleshooting Video - Avoid the following 5 mistakes:

Applies to all SuperSense level sensors (version 1 + 2, Rev. A - E):

  1. Checking the power supply
    • The sensor is connected with a cable and supplied with voltage. Check whether the incoming voltage is correct. Use a multimeter and measure between the brown (ground) and the white (DC) wire. A voltage in the range of 10 - 30 V DC must be measurable.
    • Voltage okay?
      • Yes: Go to step 2
      • No: Check power supply and fuses if necessary and test again
  2. Checking the LED on the sensor
    • If the sensor is properly supplied with voltage, the LED on the sensor must slowly dim in the colour white at intervals of approx. 3 seconds.
    • LED okay?
      • Yes: Go to step 3
      • No: Sensor is defective, please contact support
  3. Check the sensor hose for correct length (only for Mounting type A)
    • Check whether the length of the sensor hose has been selected or cut to the correct length.
    • Instructions for determining the correct length:
    • Hose length okay?
      • For SuperSense 1 (permanently mounted hose):
        • Yes: Go to step 4
        • No: The hose can be adapted by means of a new end piece (part number: SS-PIPE-FIT).
      • For SuperSense 2 (exchangeable sensor tube)
        • Yes: Go to step 4
        • No: Please adjust hose length, if necessary by purchasing a new end piece (article number: SS-PIPE-FIT)
  4. Checking the sensor hose for foreign bodies (only for Mounting type A)
    • Is the hose in good condition and free of any foreign bodies?
      • For SuperSense 1 (permanently mounted hose)
        • Yes: Go to step 6
        • No: Please clean the hose by using some washing-up liquid
      • For SuperSense 2
        • Yes: Go to step 6
        • No: Please remove the sensor hose and rinse it with water.
    • Note: Contamination rarely occurs in practice. Discoloration on the hose is normal and does not represent a fault.
  5. Check the plug nipple for foreign bodies (only for Mounting type B)
    • Unscrew the sensor from the mounting device and check the plug nipple attached to the sensor.
      • Is this in order and free of foreign bodies?
        • Yes: Go to step 6
        • No: Please remove the plug nipple and rinse with water

Other, possible sources of error:

  • Overload of the measuring unit
    • The sensors are a precise measuring device, be careful not to overload the sensor system.
    • Unless otherwise specified, tanks must always be vented and pressure-free.
    • Avoid filling the tank by making a pressure-tight hose connection (e.g. using a "Gardena connection" to connect the tank to the water pipe. Instead, ensure that only one filling hose is inserted into the tank, but without this being connected to the tank in a pressure-tight manner.
  • Mounting too close to the water pump
    • If the sensors are mounted in the immediate vicinity of the water pump, the pressure may drop when water is drawn off and the level on the display will drop significantly and a warning message may appear because it is assumed that the tank is becoming empty.
    • Make sure that there is sufficient distance to the water pump or that the water pump and sensor are not installed in the same pipe system (this is particularly relevant when measuring directly in the drainage area).
  • Tank cleaning
    • Use mild cleaners for cleaning and avoid high pressures, such as during rinsing processes.
