DRP - Dry Running Protection. CS.3W-1.5 DRP (1.1kW)

DRP - Dry Running Protection. CS.3W-1.5 DRP (1.1kW)


Price: 171.00 (Excluding VAT at 20%)

The DRP working mode is based on water conductivity, The DRP device does not work when water conductivityy is lower than 100us/cm or higher than 1000uS/cm, for this reason it can't be used in water with low salt contents, such as rain water. When the pump runs dry the DRP will stop the motor. The DRP attempts to re-start the motor automatically after a period of 30 seconds. If the pump runs dry again within 30 seconds, the DRP is programmed with the following attempts of 5 minutes, 10 minutes, 20 minutes, 40 minutes and 80
minutes. If the pump, during any of these timed cycles, runs for 30 seconds or more, the DRP will reset itself back to the first cycle. If the pump does not run continuously for 30 seconds in any of the programmed cycles (last
cycle of 4800 seconds) within the last cycle, the DRP will put the pump in "stand-by" and it has to be reset by disconnecting the power supply, i.e. pulling the motor cable from the socket. If It occurs frequently, it means that delivery of the borehole is lower than delivery of the pump installed and the pump should be replaced with the one of lower delivery.
