Default State:
For a triplex group, if all three blocks in the group are lost or if only two
blocks are lost and Voting Adaptation is selected as 3–2–0, the GMR
system software will use a selected minimum or maximum value (see
below) in voting, or hold the last value updated.
For a duplex group, select what should happen if both inputs for a
channel are lost or if one block is lost and Voting Adaptation is selected
as 3–2–0. The input can be:
set to its configured maximum value.
set to its configured minimum value.
Hold its last value.
For a simplex group, select which of the above should be done if the input
data for the channel is lost.
Maximum, Minimum: The maximum and minimum values (shown in
the next illustration) entered for an input represent the block’s
configured engineering units. The maximum and minimum values are
used in two ways. First, either the specified maximum or minimum
value can be used as the Default State if actual input data for that
channel is not available. Second, the maximum and minimum values
entered here represent the full-scale deflection for the input. They are
used by the software to monitor the point for limit discrepancy. This is
explained in more detail on the next page.
Enter a maximum and minimum value for each GMR analog input
channel by first selecting the channel (using the mouse or Tab and
Return keys).
The range for either maximum or minimum is –32767 to +32767.
