Antipumping Duty
For close and trip inputs the following rule
is applicable: During close operation, if a
trip instruction is received before the close
instruction becomes passive then the clo-
se instruction will be blocked. For the next
close operation the close instruction must
be reapplied after the trip instruction has
become passive (Figure 54).
Blocking Duty
For close and trip inputs the following
rule is applicable: If a close instruction is
received whilst a trip instruction remains
active then the close instruction is blocked.
For the next close operation the close
instruction must be reapplied after the trip
instruction has become passive (Figure 55).
Combined Blocking
and Antipumping Duty
A close command during a pending trip
command is not executed (blocking duty)
even it is pending longer than the trip
command (antipumping duty) (Figure 56).
