FRQ trip signal
(iii)
The FRQ can issue a trip signal for the function of trip circuit (TRC) when Trip is set for scheme
switch [FRQ1-UseFor]. However, when an alarm signal is required in place of the trip signal,
the user should set Alarm for scheme switch [FRQ1-UseFor]. The TRC function is discussed
separately. (See Chapter
UF/OF scheme logic
(iv)
Figure 2.17-2 shows the scheme logic for the UF and OF functions. Each stage operates
independently. PLC connection point "FRQ1-BLOCK" is provided to block the stage1 when
blocking is required by an external signal. The user can connect the PLC connection point with
an external signal using PLC function. (For more information of PLC function, see Chapter
PLC function
)
The under-voltage block (FRQBLK) element is used to block the FRQ operation, as
mentioned earlier (section 2.17.1(i)).
