Short press the "Set/Switch" button, the current indicator light will turn on, displaying the current value (1A to 63A is 50A;1A to 100A is 50A). Press the "/Reset" button to adjust the current value up to 63A (1A to 100A is 100A), and press the "/Mute" button to adjust the current value to a minimum of 1A (if you need to turn off the adjustment of the current value, then adjust it up or down again to adjust the current value to a minimum of 1A). If OFF appears, turn off the overcurrent. Short press the "Set/Switch" button, the leakage indicator light will turn on, displaying the current leakage action value (50mA). Press the "/Reset" button to adjust the leakage action value up to 90mA, and press the "/Mute" button to adjust the leakage action value to a minimum of 10mA. (If it needs to be turned off, adjust the leakage action value to the highest and then increase or decrease the leakage action value to the lowest and then decrease it. If OFF occurs, the leakage function can be turned off) f. Short press the "Set/Switch" button, and when "000C" appears on the display screen (factory set to 3 times), it indicates that the protector will reclose 3 times in case of overcurrent or leakage faults. Press the "//Reset" button to adjust the reclosing times up to 6 times. Press the "/Mute" button to adjust the reclosing times to 0 times g. Short press the "Set/Switch" button when "001d" appears on the display screen (factory setting is 1), indicating that the communication address of the protector is 1 (only with RS485 interface to set the address):1-247, press the "/Reset" button to adjust the maximum address. Press the "/Mute" button to adjust the minimum address h. Short press the "Set/Switch" button. When "ESC" appears on the display screen, press the "/Reset" button again, and the display screen will show "SURE". Immediately press and hold the "Set/Switch" button for more than 5 seconds. If the parameter settings are successfully saved, it means that the setting was successful Note::This operation is very important. If this item is not operated, the settings cannot be saved and the parameter settings are invalid. If no operation is performed for 10 seconds, it will automatically return to the voltage display interface 3. Silencing:Short press the "/Mute" button to mute the buzzer (in case of fault alarm) 4. Leakage test:Short press the "T" key to test the leakage function and reset it:a. Short press the "/Reset" button to turn on the buzzer (when the fault alarm beeps and is silenced). b. Short press the "/Reset" button to restore the coincidence time (when there is an overcurrent or leakage fault) After the installation of the protector is completed and checked for errors, the power can be connected, the "main control switch" can be turned on, and the protector will immediately connect the circuit. Press the "test" button, and the protector will immediately disconnect the circuit. The "leakage" indicator light will light up. After 10 seconds, the protector will automatically close and power on, and the protector will work normally at this time At this point, the protector has been installed correctly and can be used with confidence The protector can be tested regularly according to the above to ensure its normal function. If power is not needed for a long time, the "main control switch" can be turned off, and the protector will automatically disconnect, which is equivalent to opening the main switch (1) After power on, throw the power switch to the "closed" position, and the power indicator light will turn on, indicating that the protector is powered on_The closing indicator light is on, indicating that the protector is in the closed state, and the closing indicator light is off, indicating that the protector is in the open state (2) The closing indicator light on the protector panel is on, indicating that the power supply is normal (3) When there is overcurrent or leakage current in the circuit, the protector will immediately disconnect, and the current indicator light or leakage indicator light will light up. At this time, the protector will close for the first time after 30 seconds;If overcurrent or leakage current persists and the circuit breaker is closed immediately, the protector will be closed for the second time after 5 minutes;If the fault still exists, the protector will close for the third time after 10 minutes;If the fault still exists, the protector will close for the fourth time after 30 minutes;If the fault still exists, the protector will close for the fifth time after 60 minutes;After 5 closing cycles, the protector was restarted and checked for the circuit after 3 hours, and closed for the 6th time;If the fault still exists, the protector will enter a self-locking state and will not be reconnected;At this time, the power switch of the protector should be turned off, the fault should be eliminated, and then powered on again. The protector will automatically close Note:;The above overlap times can be set, such as::Set 3 times, after the protector only overlaps 3 times, it enters the self-locking state and will not be re closed, (4) overvoltage protection:When the power supply voltage:275V When the overvoltage setting value is reached, the protector will disconnect and the voltage indicator light on the panel will light up, entering the overvoltage protection state. When the voltage is restored, the protector will automatically close 10 seconds later. If the voltage is not restored, the protector will not automatically close. (5) Undervoltage protection>when the power supply voltage (6) is overcurrent, the number of reclosing times for electrical faults is the same. (7) Overvoltage and undervoltage:when the voltage is restored, it will automatically close after a delay of 10 seconds Modbus control commands:Please contact us if you need this product:Please contact us if you need this product! ! !
