g. Interval Programming for Hi Peak / Lo
Peak Point Types - When programming a High
Peak/ Low Peak Point, the Interval represents
the frequency the High or Low Peak value will
be reset to the value of the base point. The High
or Low Peak value will be logged on the
Alarm/Event Data Log before the value is reset
is the reset print is enabled. The interval time is
entered in a 24-hour clock format in Hour (00
through 24) and Minutes (00 through 59). The
longest time interval that can be entered is
24:00 which represents a reset interval of once
every 24 hours.
For the Interval Log function and Auto Resettable
point types, the programmable Start Time is
not necessarily the time at which the first log /
reset will occur. However, a log / reset will always
occur at the Start Time every day. The
actual first log / reset depends upon the current
time and the assigned Interval. The Recorder
calculates the first log / reset by repeatedly
adding the interval to the Start Time until the
current time is met or exceeded. See the example
below:
Current Time: 07:30
Start Time: 09:15
Timed Interval: 1 Hour
