healthy state, the echo signal is restricted to last for 200 ms by delayed pickup timer T2.
Figure 2.3-7 and Figure 2.3-8 shows ECHO logic. Users can enable ECHO operation using
scheme switch [

WIKT function
Figure 2.3-9 shows WIKT logic. WIKT can issue a trip signal on condition that a trip
permission signal has been received when POP operates. On the other hand, when UOP
operates, WIKT can issue a trip signal when a trip block signal has been stopped.
To operate WIKT, the following conditions are required:
