Scheme logic of the restart inhibit function
(iii)
Figure 2.28-18 shows the scheme logic of the restart inhibit function constructed by the
thermal state of rotor function and the starts per hour function.
The signal "Mot-RSIH CBBLK" used to block CB closing is generated by the operating of the
thermal state of rotor function and the starts per hour function. In addition, the signal "Mot-
RSIH CBCLPERM" is made by inverting the signal "Mot-RSIH CBCLBLK", which is used to
permit CB closing.
The user must construct the CB closing circuit by using the programmable BOs or PLC logic
with the signal "Mot-RSIH CBBLK" or "Mot-RSIH CBCLBLK".
