2.11.1  Setting for the operation 
To the operation, the user should set On for scheme switch [DTT*-EN]; then, the user should 
set for the scheme switch [DTT*-Output] to select an mode when the DTT function receives a 
command from the remote terminal. The user should set TRIP for the scheme switch [DTT*-
Output] when tripping the CB
1
 is required. Conversely, set BO for the scheme switch [DTT*-
Output] when tripping the CB is not required but issuing an alarm is required using the binary 
output circuit
2
. 
 
To delay for issuing the trip signal, the user can set the delay time using [TDTT*] among 
0.00 to 300.00sec.   
 
If  the  operation  of  the  autoreclose  (ARC
3
)  function  must  be  blocked  when  the  DTT 
function receives a signal from the remote end, set Block for scheme switch [DTT*-ARCBlk].
