2.4.11 Transfer Trip Function
The GRZ100 provides a transfer trip function which receives a trip signal from the remote
terminal and outputs a trip command. Two transfer trip commands are provided. The scheme logic
is shown in Figure 2.4.11.1. When the scheme switch [TTSW
∗
] is set to “TRIP”, the binary output
for tripping is driven. When set to “BO”, the binary output for tripping is not driven and only
user-configurable binary output is driven.

Figure 2.4.11.1 Transfer Trip Scheme Logic
The sending signal is configured by PLC function. If the sending signal is assigned on a per phase
basis by PLC, a single-phase tripping is available.
Figure 2.4.11.2 shows an example of the assigning signal.
The transfer trip function is available for using integral digital communication.
