Scheme logic and setting
Figure 2.18-5 shows the scheme logic of the OSTZ function. When the condition of out-of-step
is yielded, the OSTZ function can detect the motion of the loci impedance from Zone A, Zone B
to Zone C
1
. Then the OSTZ function will issue a trip command when the locus enters to Zone
C and when the locus keeps staying in Zone C for setting times [
TOSTZ1
] and [
TOSTZ2
].
The user should set scheme switch [
OSTZ-EN
]
On
in order to operate the OSTZ function.
The user should set scheme switch [
OSTZ-Output
]
Trip
to issue a trip command for the trip
circuit (TRC
2
). When the user requires outputting the trip command for the binary output
circuit (BO
3
) instead of the TRC, the user should set
BO
the scheme switch [
OSTZ-Output
].
PLC connection point “OSTZ-BLOCK” is used to blocking the OSTZ function by an
external signal. The PLC function
4
makes possible the connection with the logic.
1
Note: The OSTZ function also issues a trip command when the motion of the locus from
Zone C to Zone B, Zone A.
2
Note: Trip circuit is discussed separately. See Chapter
Relay application: Trip circuit
function.
3
Note: Binary output circuit is furnished on Binary IO module. See Chapter
Technical
description: Binary IO module: Binary output circuit.

Note: For more information, see Chapter
PLC function.
