Sampling From:
The value of the global analog will be the average of this input over
the specifi ed time period.
For example, if 1A3 is input here, the system will periodically read
the value of analog input #3 on satellite controller #1. The value
of the global analog will be the average 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
averaging cycle when a binary value goes either ON or OFF.
Sampling Rate: 1 Minutes
Window: 33 Days
Assume we are monitoring outside air temperature and 1 minute
is entered as the “sampling rate” and 33 days for the Window. The
system will read the value of the outside air temperature every
minute and then average the values until 33 days have elapsed.
After 33 days the calculation process will start over.
In the example above, GB1 goes on at the beginning of each new
month to restart the averaging process, so the end of the window is
never reached. If the end of the window is reached, the system will
restart the calculation process.
The sampling rate can vary from 1 minute to 99 hours. The window
will accept from 0-9999 minutes, hours, days, or samples.
Integral Mode: Average
There are three integral modes which can be selected by pressing
the
until the desired choice appears and then pressing
