Close Circuit Monitor
While a close circuit monitor is not included in any of the preprogrammed logic schemes, this function
may be added by using a 62 function block and a contact sensing input (INX) to monitor the close circuit.
The logic for the close circuit monitor is shown in
Figure 8-19. The output of the 62 Protection Block will
close the designated output contact (VOY) when an open breaker and open close circuit condition exists.
The S<g>-62 command is used to provide a 500-millisecond time delay to inhibit the momentary alarm
that will occur due to the timing differences between the two signals.
