I set up a solar energy pumping system and using a level replay for the preventing pump to run dry, the relay is Schneider RM22LG11MR.
the problem I have is that when I run the VFD the relay goes from NO to NC in a blinking way. even though the pump is deep in water.
the energized coil in the relay is 24VDC I took it from the VFD 24VDC output. the pump is 161m depth in the well. please if anyone has this problem before or know how to solve it, PLEASE HELP*
