It returns instantly to the initial state when the current drops below the hysteresis threshold, or when the power supply is disconnected. AC/DC control with memory The output relay changes state at the end of time delay T1 and remains latched in this position. To reset the memory function the auxiliary supply must be disconnected. Over-current function (UPPER) The time delay on energisation T2 prevents current peaks due to motor starting. The delay on upward crossing of threshold T1 provides immunity to transients and other interference, thereby preventing spurious triggering of the output relay. Under-current function (UNDER) The time delay on energisation T2 prevents the occurrence of current troughs. The delay on downward crossing of threshold T1 provides immunity to random dips, thereby preventing spurious triggering of the output relay. Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected
