December 30,1995
Either the percent ON time
(time-proportion) or valve position
(position proportion) is displayed
in the SET window. For single
control mode operation this
number is always positive
(0/50/100). The [UP ARROW] and
the [DOWN ARROW] keys
increase or decrease the percent
ON time or the valve position
toward its fully opened or closed
positions by approximately 1%.
This continues for as long as the
key is pressed. The [RIGHT
ARROW] and [LEFT ARROW]
keys force the CONTROL
OUTPUTs to increase or decrease
the percent output by
approximately 10%.
AUTOMATIC MODE In Automatic Mode the process
variable is displayed in the
PROCESS display, the
SETPOINT is displayed in the
SET display, and control action is
computed based upon the PID
parameters and the input(s).
Pressing and holding the [LEFT
ARROW] key will cause the SET
display to show the control action
as described previously in
"Manual Mode.”
