Relay selection for checking synchronization
Figure 4.6-16 exemplifies a bus-bar arrangement used as an example for check synchronization.
In this example, the SYNCHK_Ry1 relays require the voltage signals† V3, V4, and V1. This is
because DS1 and DS3 are closed, but DS2 is open; the selection of SYNCHK_Ry1 is initiated
by the reception of the “SYNCHK_Ry1_selection” signal. The “SYNCHK_Ry1_selection” and
“SYNCHK_Ry2_selection” signals are generated by logic programmed by the user; hence, here
the signal “SYNCHK_Ry1_selection” is connected with the PLC connection point
“SYNC01_RY1_USE_STS”‡.

†Note: The relationship between the injected voltage-signals and the SYNCHK_Ry
function is discussed in section 4.6.6.
‡Note:The user should also connect the “SYNCHK_Ry2_selection” signal with the PLC
connection point “SYNC01_RY2_USE_STS”. Users should note that Figure 4.6-16
is provided for explanation/information; the user is required to program relay-
selection logic using the PLC function that responds dynamically to configuration
changes that occur as a consequence of CB and DS operations.
In Figure 4.6-16 , two signals are used for relay selection, but the user should note that
the selection-signals are provided in accordance with the actual line and bus-bar arrangement.
Figure 4.6-17 shows the overall logic used for the selection. The user can program the selection-
signals using the PLC function.
