Setting Up Start Time - If the Start Time is correct, press ENTER and proceed to Interval. If the
Start Time is not correct, press NO and the display reads “str hrs
ÎXXÍ”. (for STaRt hours). Use
the Numeric Keypad to enter the desired Start Hours. Up to 23 hours may be programmed. When
the correct Start Hours are displayed press ENTER and the display reads “str mins
ÎXXÍ”. Use
the Numeric keypad to enter the desired Start Minutes. Up to 59 minutes may be programmed.
When the correct Start Minutes are displayed, press ENTER and the display returns to “start
XX:XX”. If the Start Time displayed is correct, press ENTER and the display reads “intrvl XX:XX”.
Setting Up Interval Time - It the displayed Interval Time is correct, press ENTER and the display
returns to “Auto reset” in the Reset Control Setup Menu. If the Interval Time is not correct, press
NO and the display reads “int hrs
ÎXXÍ”. Use the Numeric keypad to enter the desired Interval
Hours. Up to 23 hours may be programmed. When the correct Interval Hours are displayed press
ENTER and the display reads “int mins
ÎXXÍ”. Use the Numeric keypad to enter the desired
Interval Minutes. Up to 59 minutes may be programmed. When the correct Interval Minutes are
displayed, press ENTER and the display returns to “intrvl XX:XX”. If the Interval Time displayed is
correct, press ENTER and the display returns to the “Auto reset” prompt in the Reset Control
Setup Menu.
Interval Programming for Totalize Point Types - When programming a Totalization Point, the
Interval represents the frequency of which the Totalization value will be reset to zero. The Totalization
value will be logged on the Alarm/Event Data Log before the value is reset if the reset print is
enabled. The interval time is entered in a 24-hour clock format in Hours (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.
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
09:15 Programmed Start Time
10:15
11:15
12:15
Note: The Interval (1 hour) added to the Start Time yields log/reset times.
