Page 4: Introduction
The controller is easy to set up with an initial push button calibration and individual parameters can be fine-tuned. A nXt-Protect controller is particularly useful where there is the need to control and protect pump installations managing the automatic operation through a variety of switching methods without the need to create a bespoke control solution. -

Questions and answers
Can my float switch be 50m away from controller
The documents do not specify a maximum distance for the float switch from the controller. However, they mention that the installing technician must ensure the cable cross-section meets AS/NZS 3008 requirements, considering cable length, type, and current draw. Therefore, a float switch can be located 50 meters away if the correct cable size is used according to these standards.
