PLEASE NOTE: This is not 3 Phase to 3 Phase Changeover switch. This is 3 Phase to 1 Phase changeover switch. ATR automatic phase changeover relay is designed to switch the fault phase to the normal phase from errors that may arise from mains high and low voltage.
Current & voltage protection relay is designed to protect devices with sensitive operating voltage & current values from errors that may arise from mains voltage and Overload. Make the connections of the device according to the connection type. Otherwise, the device may be damaged. Adjust the over-current and high & low voltage and settings of the device according to the operating current and voltage values of the load you will use.
Make the connections of the device according to the connection type. L1 is trouble-free and energizes relay, L1 led is turned on, output led LOAD is turned on. When the L1 under/over voltage, wait for the delay timings, cut off the L1 phase and (L1U<)error led turned on. Now it will automatically turn on the fault-free L2 phase after the delay of D-T, the L2 led turn on, and the output led LOAD is turn on. When L2 is over/under voltage, same process is followed to move the connection to L3.
When the L3 is also under/over voltage, wait for the delay timings and cut off the L3 phase and turn on (L3 U>)error LED. In this state, L1, L2 and L3 are all faulty, so disable the output, wait for any one phase to return to normal and then turn on the load again.
