Prot-Zb_Ch1; Prot-Zf_Ch1 - Toshiba GR200 Series Instruction Manual

Command-trip output and Command-Transfer-trip output are shown in Figure 2.4-4 to
Figure 2.4-6. If replica setting [BayDevice_CH*] = Coupler, and the busbars connected by the
coupler are bridged, tripping the coupler CB is forbidden when the setting [CoupTpBlk] =
Block. Contrarily, tripping the coupler CB is not blocked when the setting [CoupTpBlk] = Non.
When Command-trip logic and Command-Transfer-trip need to operate securely, set On
for setting [COMTP-FS]; then all Command-trip and Command-Transfer-trip will be allowed
with the Fail-safe operation (FS). On the other hand, Command-trip and Command-Transfer-
trip operate without the FS operation when Off is set for the setting [COMTP-FS].
