Do you battle with Phase Sequence Errors on the Motorscopes.
This function is to protect the pump from turning the wrong direction after installation. That means that the rotation still needs to checked. And note that the Motorscope only accepts one direction. So swap phases at the Isolator for the Motorscope and at the contactor for the pump.
How to check if the direction is correct?
By checking the direction for the most flow and pressure.
Please note that changing the direction at the outlet of the panel does not influence the Motorscope. The Motorscope reads the incoming phases from the supply. Also making changes on the harness of the panel, is like changing a program.
When a Phase Sequence Error is displayed. Two Phases needs to be swapped at the Isolator.
Please see attached slides for more information.
