The electronic protection system of the UZE 2000 is designed to protect single-phase pump motors against overload and dry running. UZE 2000 controls the operation of the pump (operating current). In the event of an overload or dry running and the maintenance of such a state for a period of 6 seconds, the pump is turned off, which is also signaled by a red FAILED diode. The system then waits 15 minutes and checks to see if the problem has been resolved (e.g. if water has already appeared in the well).
