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.
