Sampling From:
The value of the global analog will be the accumulated total of this
input over the specifi ed time period.
For example, if GA20 is input here, the system will periodically
read the value of analog global #20. The value of the global analog
will be the accumulated total of the readings over the specifi ed
time period.
Automatically reset by GB1 being ON
This allows you to have the system automatically restart the
accumulation cycle when a binary value goes either ON or OFF.
Because this second fi eld is a “choice” fi eld, the list of available
choices will be displayed at the bottom of the screen:

ANALOG Global #: 32 Name is GA32

Unit of Measure: 7 Gal
In Local Set this global defaults to LAST VALUE

Sampling Rate: 1 Minutes
Window: 24 Hours
Assume we are monitoring fuel oil usage in gpm, and 1 minute is
entered as the sampling rate and 24 hours is entered for the Window.
The system will read the value of the fuel oil usage rate (gpm)
every minute and then add the current value to the accumulated
total until 24 hours have elapsed. After 24 hours, the calculation
process will start over.
The sampling rate can vary from 1 minute to 99 hours. The window
will accept from 0-999 minutes, hours, days, or samples.
Analog Global Screen’s WCC III Logical Address is GAXXX, where GA = Global Analog and XXX = Global Analog Address
