3.18 Manual Closing Function
3.18.1 Manual Closing Theory
This relay supports manual closing function (local or remote closing). The manual closing can be
initiated a local input signal (through a binary input or the control panel) or remote closing signal
from a supervision and control system (SAS, SCADA). Three check modes described below can
be selected for the manual closing function.
The logic diagram of the manual closing function is shown as below.

Figure 3.18-1 Logic diagram of the manual closing function
Where:
“ManCls_Cmd” is the manual closing command;
“25M.Ok_SynChk” is the result of the synchronism check of the manual closing function;
“25M.Ok_DdChk” is the result of the dead check of the manual closing function;
“25M.BI_EnSynChk” is the binary input for enabling the synchronism check mode, and it can
be configured through the PCS-Explorer configuration tool auxiliary software;
“25M.BI_EnDdChk” is the binary input for enabling the dead check mode, and it can be
configured through the PCS-Explorer configuration tool auxiliary software;
[25M.En_SynChk] is the logic setting of the synchronism check of the manual closing;
