now calibrated and knows the minimum
and maximum positions of the slide valve
it controls. Now the capacity or volume
channel of the Vission/Vantage can be
calibrated.
19. Use the Dec button to move the actuator
towards its minimum position while
watching the millivolt readout on the
Vission/Vantage screen. Discontinue
pressing the DEC button when the milli-
volt reading in the “Current” window above
the “Set Min” button is approximately 500
millivolts.
20. Now use the DEC and INC buttons to
position the slide valve until a value close
to 300 millivolts is on the screen. Then,
press the “Set Min” button for the capacity
or volume slide valve window to tell the
controller that this is the minimum
millivolt position. Note: The value in the
“Current Cap” or “Current Vol” window
has no meaning right now.
21. Use the INC button to rotate the actuator
towards its maximum position while
watching the millivolt readout on the
controller screen. Discontinue pressing the
INC button when the millivolt reading in
the “Current” window is approximately
9200 millivolts (7900 millivolts for the
2783J qualified analog boards). You are
nearing the mechanical stop position.
22. Pulse the INC button to carefully move the
slide valve until the millivolt readout
“saturates”, or stops increasing. This is
around 9500 millivolts (8400 millivolts for
2783 qualified analog boards).
23. Pulse the DEC button until the millivolts
just start to decrease. (This is the point
where the channel drops out of
saturation).Adjust millivolt value to 300
millivolts below recorded maximum milli-
volts in step #22.
24. Press the “Set Max” button.
25. Press the “Main” button to complete
calibration and exit the “Slide Calibration”
screen. The controller will automatically
energize the actuator and drive it back to
its minimum position (below 5%) for pre-
start-up.
26. Note: Now the “Current Cap” or the
“Current Vol” value will be displayed in
the window on the “Main” screen and the
“Slide Calibration” screen.
27. Gently lower the plastic cover over the top
of the actuator to where it contacts the base
and o-ring seal. After making sure the
cover is seated properly, gently tighten the
four #10 screws.
Caution: The plastic
cover will crack if the screws are over
tightened.
28. Enable the “Slide Non-Movement Alarm”
by going to the “Setup” menu and choosing
“Alarm Enable” for the “Slide Non-
Movement Option”.
29. This completes the calibration for this
channel either capacity or volume. Repeat
the same procedure to the other channel.
