•     Product status statement 
•     If a voltage fault is detected during the relay's reset/start delay count, the output relay turns on and the fault indicating LED lights up 
     The operating voltage and current values will be displayed on the screen when the relay is operating nonnally. If a voltage or current fault is         detected, the output relay turns on and the fault indication LED lights up 
Voltage failure: If the input voltage is detected to trip back to Hys after a voltage failure; During counting the relay will automatically reset reset/start delay fault indicator light off working voltage and current value flashing screen 
Current failure: When the relay fails due tocurrent trip, it will reset automatically. Reset/start delay durring counting, farure indicator LED off operating voltage and current value flashing on the screen.
