Fig 1 2 1 1 RELAY OPERATING MODE Switch 1 is used to set the operating mode of the output relay In the fail safe mode the output relay energizes when the earth leakage circuit is not tripped In the fail safe mode non volatile memory retains the trip status of the SE 704 If tripped and the supply voltage is cycled the SE 704 will remain tripped with the trip relay de energized and the TRIP LED on until reset In the non fail safe mode the output relay energizes when an earth leakage trip occurs In the non fail safe mode trip status 1s not retained in non volatile memory 2 1 2 FILTER SELECTION Switch 2 is used to select the filtering algorithm for a fixed frequency 50 60 Hz or variable frequency application for earth leakage trip levels of 500 mA or less The peak detection algorithm is used for settings greater than 500 mA regardless of the filter selection The FIXED FREQUENCY setting uses a DFT filter that allows lower trip levels to be used by rejecting harmonics that can cause nuisance tripping The VARIABLE FREQUENCY setting uses a peak detection algorithm with a wider band width for fault detection in variable frequency drive applications SE 704 Earth Leakage Monitor Page 1 Rev 7 C 082814 2 1 3 CT VERIFICATION Switch 3 is used to enable CT verification In the ON position a trip will occur if the SE CS30 current sensor is disconnected 2 1 4 RESET MODE Switch 4 is used to select autoreset or latch
