When connected with MI or MP current trans- former (using the 0.4 - 4 Vp range) they can monitor 1- phase or 3-phase AC cur- rents up to 500 A. Example 1 (connection between termi- nals Z1, Y1 or 8, 9 - latch function enabled) The relay operates and latches in operating position when the measured value exceeds the set level. Pro- vided that the voltage has dropped min. 4% below the set point (see hysteresis), the relay releases when the interconnection between ter- minals Z1, Y1 or 8, 9 is inter- rupted or the power supply is interrupted as well. Range - Level Setting Example 2 (MI CT) (no connection between ter- minals Z1, Y1 or 8, 9) The relay operates when the current flowing through the CT exceeds the set level. It releases when the current drops min. 4% below the set level (see hysteresis) or when power supply is inter- rupted. Example 3 (MP CT) (no connection between ter- minals Z1, Y1 or 8, 9 - latch function disabled) The relay operates when the maximum current flowing through the CT exceeds the set level. It releases when the maximum current drops min. 4% below the set level (see hysteresis) or when power supply is interrupted. Adjust the measuring range setting the DIP switches 1 to 4 as shown below. To access the DIP switches open the grey plastic cover using a screwdriver as shown below. Centre knob: Setting of voltage on relative scale: from 10 to 110% of the full-scale value. Hysteresis: Approx. 4% of set value, it can be extended by insert- ing a resistor between termi- nals Z1, Y1 or 8, 9.
