State Display of the Limit Features
When the voltage V-LIMIT protection, the current I-LIMIT protection, or the power limit
(internal loss) protection is activated, the limit state display shows which protection feature
has been activated.
How to Set and Check Activation Points
Mode and selectable items

Voltage limit V-LIMIT +V.LIM: The voltage was limited by the positive voltage activation point.
-V.LIM

In unipolar mode, -V.LIM is ignored.
Current limit I-LIMIT +I.LIM: The current was limited by the positive current activation point.
-I.LIM: The current was limited by the negative current activation point.
Power limit P-LIMIT P.LIM: The power was limited by the sink power activation point.
