Operation
UNIPRO 3.5
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.”
