Time Zones
When using Time Zones, each zone has its
own set of gain and threshold values for each
pipe. Each day is split into three time zones,
the current zone is indicated by ‘>>’ when the
menu is entered.
The start times for the three zones each day
are entered with the required gain and
sensitivity levels for that zone. The >>
indication is now used to show which time
zone is being edited.
The copy button copies the times and
sensitivity levels to the following day.
Latch Levels
Each pipe can be set up to latch at any one of the alarm levels. This
means that once the selected level has been reached it requires manual
intervention to reset the unit. The default is ‘Latch at pre-alarm’. Any levels
attained above the ‘latch level’ will be retained until reset.
