The user encountered an issue with the AD-PQMON-SL not triggering a dip event when the single-phase voltage input was below 57.15V. The final answer explained that the dip event logic depends on the selected network type, and the default 3-phase setting causes the Pqmon to continuously trigger a dip event due to the other two phases being under the threshold. The solution is to connect the same voltage to all three phase inputs for a proper test.

Expected Result:
When the single-phase voltage input <57.15V, a dip event is triggered.
Hi YongLawrence , As Gabriel said the dip event logic on the Pqmon depends on the network you selected. Since the default setting is 3-phase, the Pqmon will trigger a dip event because the other two phases are always under the threshold, so it will not recover from the dip event. For a dip event to be acknowledge, the voltage should recover based on the hysteresis you set. For a quick test you can connect the same voltage to all the three phase inputs and run again the test. I suppose that you already tested the other event types and they worked fine, since the swell and interrupt conditions are met also by the other two inputs that are not energized.
