Example 2 of short delay tripping simulated by software is shown below:
Example3 of setting earthing alarm threshold current is shown below:②Setting state: press “Set” button in default interface to enter into setting interface. Current protection parameters, overload pre-alarm
value, earthing alarm threshold value and delay time can be queried or changed in setting state. Tripping can be simulated by software. In
this state, “▲” or “▼” button can be pressed to add or subtract value when “SET” indicating lamp is flickering. Don’t forget to
press “Enter” button to save data after setting.
Example 1 of changing long delay time is shown below:
3 times
③Query state: press “Check” button in default interface to enter into query interface. Last 8 fault records, last 8 alarm records, breaker
operation times, life record and thermal capacity can be queried in query state.
