starting recur during the hold time period then the time of the renewed starting
will be added to the time period stored. When the starting times sum reach the
tripping time value determined by the P631 then the corresponding signal will be
issued. Should starting not recur during the hold time period then, depending on
the setting, the memory storing the accumulated starting times value will either
be cleared without delay or according to the characteristic set. In
, the effect of the hold time is shown by the example of a phase
current stage.
