Value to be averaged
You may input up to 8 analog values to be averaged. The values
may be input in the form of 12A4 (analog input #4 on satellite
controller #12) or GA20 (global analog #20).
If a satellite controller that has an analog input used on this screen
stops communicating, then a value will be missing from the list.
The statement at the bottom of the screen allows you to specify a
default value for the missing values. However, if several inputs are
missing, you may default to a fi xed value. Consider the following
example:
Substitute 72 for each unavailable value until more than 3 values
are unavailable, and then use 70 as the value for this global.
If one analog input on this screen is lost, then 72 will be substituted
for the lost value. If more than 3 analog input values are missing
from this screen, the value of the global will default to 70.
Range
The system has the capability of generating an alarm if the value
of this global analog is either inside or outside of the desired range.
If inside is selected, an alarm will be generated when the value of
the global analog is within the two limits specifi ed. If outside is
selected, an alarm will be generated if the value of the global is
outside the limits specifi ed.
Low Limit High limit
The Low and High Limits can be either an Address or a Value.
When you move the cursor to this fi eld, the word Address or Value
will appear. Since this is a choice fi eld, press the
until the desired choice appears and then press .
If you select “Value” as the choice for this fi eld, you can enter a
number which will serve as the alarm limit.
If you select “Address,” you can specify an address such as an
analog input or global analog to be used as the alarm limit.
