Here, the first three conditions are logically “anded” together to drive Virtual Output 2.
VO2, in turn, is configured to initiate a fault distance calculation on B1. Line to line fault

5.3.8 Periodic Triggers
Four independent periodic triggers are available that can be used to initiate all of the
actions listed in section 5.3 above. The timers for these triggers are configured to
individually set the period and start time for each trigger on the Timers page of the 70
Series Configurator as shown below:
The period can be set in increments of minutes up to a maximum of 24 hours. Likewise,
the time of day for the timer to start can be specified in increments of one minute.
Note that if the number of minutes in a day is not evenly divisible by the configured period,
then the start time has little impact except at boot up. For example, if the period is
configured for 7hrs and the start time is 0430hrs then the first day after the device starts
the timer will activate at 0430hrs, 1130hrs, 1930hrs. And then on the second day, it will
activate at 0230hrs, 0930hrs, 1630hrs, 2330hrs., etc

The activation status of the timers is available as a binary point in the list of
'Measurements to Trigger On' in the Recorder Triggers page (see screen below). The
