... L2 L3 Undervoltage alarm indicator Undervoltage relay Note: 1. The K8AB-PM output relay is normally operative. 2. The power ON lock prevents unnecessary alarms from being generated during the instable period when the power is first turned on. There is no relay output during timer operation. 3. Phase loss is detected by L1, L2, and L3 voltage drops. ...

... Unit operates. Operating Time Adjust the slide resistor so that the voltage applied to the K8AB terminals is 120% of the set value (for overvoltage detection) and 80% of the set value (for undervoltage detection) when the auxiliary relay operates, as shown in connection diagram 2 ...

... In the interest of product improvement, specifications are subject to change without notice. Q Overvoltage Detection When Only One Phase Exceeds the Overvoltage Threshold The K8AB-PM@ monitors each of the three-phase voltages. This means an overvoltage is detected if even only one phase exceeds the threshold value. The same applies to undervoltages. ...
