I>1 Function
This setting determines the tripping characteristic for the first stage overcurrent element.
I>1 Current Set
This sets the pick-up threshold for the first stage overcurrent element.
I>1 Time Delay
This sets the DT time delay for the first stage overcurrent element.
I>1 TMS
This is the Time Multiplier Setting to adjust the operate time of IEC IDMT curves.
I>1 Time Dial
This is the Time Multiplier Setting to adjust the operate time of IEEE/US IDMT curves.
I>1 K (RI)
This setting defines the TMS constant to adjust the operate time of the RI curve.
I>1 Reset Char
This setting determines the type of Reset characteristic used for the IEEE/US curves.
I>1 tRESET
This setting determines the Reset time for the Definite Time Reset characteristic.
I>2 Function
This setting determines the tripping characteristic for the second stage overcurrent element.
I>2 Current Set
This sets the pick-up threshold for the second stage overcurrent element.
I>2 Time Delay
This sets the DT time delay for the second stage element.
