Notes
The primary to secondary scale factor used by the Summation Channel is the
same as that of its first input channel.

Element Identifies the group to which this channel belongs. The Element forms
the first part of the channel name. The Element is selected when the
channel is created and is fixed once assigned when you are working
in the Element Tree view.
Type Identifies the type of signal being applied to this input channel. The
Type forms a part of the channel name (Element:Type:Description).
Selecting the appropriate Type can simplify channel naming by elimi-
nating the need for the optional Description field (e.g. Line #1:IaSum
uniquely defines the channel). Initially set when the channel was cre-
ated, the Type can be changed to refer to a different phase as
needed.
Description Optional field (12 characters). Provides an additional description of
the channel that forms part of the channel name. Use if Element
Name and channel Type do not sufficiently identify the channel.
(“Channel Grouping and Naming” on page 8-7).
Summation Index Identifies the summation channel. Unlike the analog and external
input channels, this is not associated with a hardware input, but sim-
ply identifies which of the internal virtual summation channels will be
used.
You can select any available channel; the only restriction is that
nested summations require the input summation to have a lower
Summation Index. If the only option is “undefined”, you have already
used all available channels.
Input 1, Input 2,
Input 3 Identifies the channels to be used in the summation. The available list
includes all previously defined analog channels and any summation
channel with a lower summation index number. The list grows auto-
matically as you define new channels.
