This mode is used with
slidewire feedback. Output
l is used to drive for more
feedback and Output 2 is
used to drive for a smaller
feedback. The percent
output is used as a setpoint
for the slidewire feedback.
A deadband of .5% is used
to prevent hunting.
Position without Feedback
This mode is used with a
motorized valve with no
feedback. The change in
percent output is used to
compute a drive time as a
percent of the cycle time.
For example, if the cycle
time is 30 seconds and the
percent output changes
from 40% to 60% then
Output l will be ON for 6
seconds (20% of 30
seconds). If the change was
in the opposite direction
then Output 2 is turned
ON. If the percent output
is at its limits (0 or l00 for
single, and l00 or -l00 for
dual) then the appropriate
output will remain ON
continuously.
