Transfer Trip Function - Toshiba GRL100-701B Instruction Manual

2.6 Transfer Trip Function

The GRL100 provides the 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 2.6.1. 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.
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.
