TECHNICAL FEATURES AND REGULATIONS SET POINT This command fixes the set point VM (fig.3) in the range from 80% to 130% of VN (by means of a small screwdriver). HYST This command fixes the set point Vm (fig. 3) at a lower level respect VM. Such value can be set within a reduction from 5% to 20% of the value set for VM. (by means of a small screwdriver). T Delay timer (0,5÷7 sec) adjustable by screwdriver on the front. It is activated when the voltage goes below Vm. VISUALIZATIONS ON GREEN LED: supply on RELAY ON RED LED: internal relay on MODE OF OPERATION See fig. 3. SETTING Adjust VM and Vm using a DC tester. INSTALLATION See fig. 1 or 2. (Wiring to an electrical board with a differential relay and a sectionalizing switch). The length of every wiring must be less than 30m.
