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
