is established when the binary input signal (PLC signal) CRT_BLOCK is "0" and the scheme
switch [CRSCM] is set to "ON" as shown in Figure 2.4.1.6.

The service condition of the external main protection in duplicated scheme is input with the binary
input signal (PLC signal) M-PROT_ON. The command protection in Table 2.4.1.1 is out of
service when both main protections are out of service.

The zone 1 tripping mode at each position of the switch [Z1CNT] is as follows:
Position 1: When the command protection is in service, zone 1 executes instantaneous tripping
and starts autoreclose. Zone 1 performs single-phase tripping and reclosing or three-phase tripping
and reclosing depending on the reclose mode of the autoreclose function and the type of faults
(single-phase faults or multi-phase faults). If the autoreclose is out of service, zone 1 performs
instantaneous three-phase final tripping for all faults.
If the command protection is out of service, zone 1 performs instantaneous three-phase final
tripping.
Position 2: Zone 1 performs three-phase tripping with a time delay using timer TZ1 if the
command protection is in service, and it performs three-phase tripping instantaneously if the
command protection is out of service and does not start the autoreclose.
Position 3: Zone 1 tripping is blocked if the command protection is in service, and instantaneous
three-phase tripping is performed if it is out of service. Autoreclose is not started.
Position 4: Zone 1 executes instantaneous tripping irrespective of the command protection
conditions and initiates autoreclose. This instantaneous tripping becomes single-phase tripping or
three-phase tripping depending on the autoreclose mode and type of faults (single-phase faults or
multi-phase faults). If the autoreclose is out of service, zone 1 performs instantaneous three-phase
final tripping.
Position 5: Zone 1 performs instantaneous three-phase final tripping irrespective of the command
protection.
Zone 1 Trip Mode Control is performed using PLC function as shown in Figure 2.4.1.7. By
changing the PLC default setting, the Z1 trip can be controlled independently of the [Z1CNT]
setting.
