Mode 3: Integral
Sampling From:
The value of the global analog will be the average of this input
using the sliding window averaging method.
For example, if 3A1 is input here, the system will periodically read
the value of analog input #1 on satellite controller #3. The value of
the global analog will be the average of several of the most recent
readings, depending on how other inputs on this screen are fi lled
out.
Automatically reset by GB1 being OFF
This allows you to have the system automatically restart the
averaging 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:
<OFF, ON>
Make your selection by pressing the <space bar> once for each
choice until the desired mode type has been selected, and then
press
<Enter> .
Sampling Rate: 3 Minutes Window: 10 Samples
Assume we are monitoring building kW, and 3 minutes is entered
as the sampling rate, and 10 samples is entered for the Window.
The system will read the value of the building kW every 3 minutes
and then average the 10 most recent readings. The value of this
global analog will be the average kW for the last 30 minutes. The
maximum number of samples allowed is 11.
The sampling rate programmed amount of time can be in minutes
or hours. Because this is a “choice” fi eld, the list of available
choices will be displayed at the bottom of the screen:
<Minutes, Hours>
Make your selection by pressing the <space bar> once for each
choice until the desired time frame has been selected, and then
press
<Enter> .
