Definitely! Even if your device is no longer covered by the guarantee, we will do our best to get it up and running again. Repairs cost between €30 and €42 depending on the device. Further information can be found in our repair and service conditions. In the unlikely event that we are unable to repair your device, we will keep you informed and endeavour to find a suitable solution.

In general, repaired devices leave our factory again within a week. Whilst we strive to deal with all complaints as quickly as possible, there may sometimes be a slight delay due to the extent of the fault and complexity of the tests required. We ask for your understanding in this matter.

Every device initially undergoes an electric strength test in accordance with EN 60950. This involves using a test voltage of 4.6 kV to check whether there is an unintentional connection between the live or neutral conductor and the sensor earth.

Following this, the actual test program is started, which measures all inputs and outputs, one after the other. If a fault is detected, this is shown on the controller display screen. This provides the production team member assigned to the device with a starting point from which to begin the repair work. If none of the tests are able to detect a fault, yet the fault description clearly indicates a malfunction, a member of the quality assurance team performs a further (more "in-depth") test.
