CALIB Valve position feedback (input 2) must be
calibrated prior to startup to use the controller
for position proportioning control.
The feedback signal always uses input 2
(option board required) and may be a slidewire
feedback, as shown in Figure 9, or other
electrical input.
OPEN POS xxxxx = Valve Stem Position Feedback.
When this reaches a maximum value (i.e. stops
changing) the valve is fully open. Scrolling will
record this as the 100% open feedback value.
CLSD POS xxxxx = Valve Stem Position Feedback.
When this reaches a minimum value (i.e. stops
changing) the valve is fully closed. Scrolling
will record this as the 0% open (100% closed)
feedback value.
