Postfault recording time (PostFaultRecT) is the maximum recording time after thedisappearance of the trig-signal (does not influence the Trip value recorder (TVR)function).Recording time limit (TimeLimit) is the maximum recording time after trig. The parameterlimits the recording time if some trigging condition (fault-time) is very long orpermanently set (does not influence the Trip value recorder (TVR) function).Post retrigger (PostRetrig) can be set to Enabled or Disabled. Makes it possible to chooseperformance of Disturbance report function if a new trig signal appears in the post-faultwindow.PostRetrig = DisabledThe function is insensitive for new trig signals during post fault time.PostRetrig = EnabledThe function completes current report and starts a new complete report that is, the latterwill include:• new pre-fault- and fault-time (which will overlap previous report)• events and indications might be saved in the previous report too, due to overlap• new trip value calculations if installed, in operation and startedOperation in test modeIf the IED is in test mode and OpModeTest = Disabled. Disturbance report function doesnot save any recordings and no LED information is displayed.If the IED is in test mode and OpModeTest = Enabled. Disturbance report function worksin normal mode and the status is indicated in the saved recording.14.6.3.2 Binary input signalsUp to 352 binary signals can be selected among internal logical and binary input signals.The configuration tool is used to configure the signals.For each of the 352signals, it is also possible to select if the signal is to be used as a triggerfor the start of the Disturbance report and if the trigger should be activated on positive (1)or negative (0) slope.TrigDRN: Disturbance report may trig for binary input N (Enabled) or not (Disabled).TrigLevelN: Trig on positive (Trig on 1) or negative (Trig on 0) slope for binary input N.1MRK 505 337-UUS - Section 14Monitoring425Application manual
