Permission signal "SYNC01_SLD_VCS"†
The "SYNC01_SLD_VCS" signal is transferred to the DPSY01 select-logic. For example,
suppose the DPSY01 function is given permission to operate when any voltage-condition is
satisfied, then the user should set On for the scheme switches [SYNCHK01-LRDIEN],
[SYNCHK01-DRLIEN], and [SYNCHK01-DRDIEN].
For example, if the DPSY01 function is required to operate when the voltage condition
"LRDI" is confirmed (Table 4.6-4.(4)), just set On for the scheme switch [SYNCHK01-LRDIEN].
User programmable pick-up delay timers are available for the conditions "LRDI" and
"DRLI" (Table 4.6-4.(1 and 4)); hence the user can set a desired value for the setting
[SYNC01_TLRDIDRLI]; similarly, a desired value can be applied for the setting
[SYNC01_TDRDI] for the condition "DRDI" (Table 4.6-4.(3)).
†Note: This signal is required for CB closing in the select logic. For more information, see
separate section
Permission signal "SYNC01_SYN_CLC"‡
The "SYNC01_SYN_CLC" signal is input to the DPSY01 operate-closing-logic as a permissive
signal. The DPSY01 function is allowed to operate when any voltage-conditions except "LRLI"
is satisfied in the DPSY01 operation.
‡Note: This signal is required only for CB closing in the operate-closing logic. For more
information, see separate section
Adding other voltage-conditions using PLC signals
(iii)
The user can add a user-preferred condition to the logic signal using PLC connection points.
In the SYNCHK1 logic, points "SYNC01_LLV_CL_ECP, _LDV_CL_ECP, _DLV_CL_ECP, and
_DDV_CL_ECP" are provided†. Similarly, points "SYNC02_LLV_CL_ECP, _LDV_CL_ECP,
_DLV_CL_ECP, and _DDV_CL_ECP" are provided in the SYNCHK2 function.
†Note: For more information on PLC programing, see chapter
Relay selection using PLC signals
(iv)
Either SYNCHK_Ry1 or SYNCHK_Ry2 function can be chosen for SYNCHK1 operation. On
this account, points "SYNC01_RY1_USE_STS and _RY2_USE_STS" are provided and the user
can choose either for use in conjunction with
"SYNC02_RY1_USE_STS and _RY2_USE_STS" are provided for SYNCHK2 operation. The
purpose of the choice is discussed in section 4.6.5.
