| Configuration |
using DIP switches: switch S1 Position I no-load current: In the no-load current principle, the relay becomes active when the limit is reached. Position II closed-circuit current: In closed-circuit current mode, the relay is activated when power is applied. The relay is deactivated when the limit is reached. via a potentiometer |
