  TRIP commands for opening the CB poles 
The ZG function issues a per-phase trip signal so that a per-phase TRIP COMMAND will be 
generated in the TRC function; set a single-phase trip (1P) mode for scheme switch [Z*G-TPMD]. 
The user can also set a three-phase trip (3P) mode if the TRIP_COMMANDs does not need to 
issue  separately.  Note  that  the  TRIP_COMMANDs  will  be  issued  for  the  CB  in  the  TRC 
function after collecting signals from the other functions. Remember that the user should set 
1-PHASE for the scheme switch [TP-MODE] in the TRC for 3P mode. The user should recognize 
that the settings of the [Z*G-TPMD] (see Figure 2.10-45 etc. and Figure 2.10-51) and the setting 
[TP-MODE] (see Figure 2.33-3) have cooperation to trip the CB correctly. 
Note: For your information, the settings of TRC function affect the other trip signals 
from other functions. See
