Detecting erroneous operation
(i)
Operation logics
The TCS has six sets of monitoring logic (TCS1 to TCS6), as shown in Figure 10.3-1. For
example, the TCS1 logic issues a signal “TC1_Fail” when the following conditions are
determined in the TCS1 logic:
Both signals at PLC connection points “TC1_FAIL_SIGNAL1” and “TC1_FAIL_SIGNAL2”
being absent for more than 0.4 sec.
Either
On
or
OPT-On
† being set for scheme switch [
TCS1-EN
].

†Note: If the user wishes to add a user-programmed condition for the TCS1 decision, set
OPT-On
and connect the user-programmed signal at PLC connection point
“TC1_FAIL_COND”. The TCS1 monitor will then only be available when a user-
programmed signal is present at PLC connection point “TC1_FAIL_COND”.

Applications
Example1
Figure 10.3-2 provides an application example of the TCS function. Two binary-input signals
are assigned to PLC connection points “TC1_FAIL_SIGNAL1” and “TC1_FAIL_SIGNAL2”.
When the trip circuit is healthy, a small current will flow in the BI circuits, the CB auxiliary
contacts, and the trip coil. This small current can be observed to flow in both the CB-open
condition and the CB-closed condition. If the small current supplied to the trip circuit is lost,
