Stroking the Valve
‐
CentriFeeder with ICV only
Stroking the Integrated Control Valve is a way of se ng the posi on sensor output to corre
‐
spond to the actual stroke or range of travel of the valve’s blade. Stroking the valve may be
required if the electronics package is replaced or the HMI is reprogrammed, however, new
installa ons will typically include a properly stroked valve that will not need to be adjusted.
Please note that the opera ng stroke of the valve is 3.5”. Mechanical Stops are the actual,
mechanical endpoints (fully open and fully closed) of the valve’s stroke. In order to properly
stroke the valve, the electronic endpoints should be moved from these actual stops to 1% un
‐
der the de
fi
ned closed posi on and to 4% over the de
fi
ned open posi on. This will prevent
damage to the valve.
To stroke the valve, you must access the Posi on Sensor page. To access this page press the
ADV Bu on from the TOP (Main Menu) page. Then, press the PID #2 Tuning Bu on and
fi
nal
‐
ly, press the Posi on Sensor Bu on. You should now be on the ADV.PID2.SENSOR page seen
below.
Step 1
: Move the valve to the mechanical stops by depressing the Open or Close arrows.
DO
NOT PRESS THE RED CLOSE or OPEN PUSH BUTTONS
.
The large arrow produces a
hard movement command and the small arrow produces a so er movement
command. Use the small arrow for all movements towards the stops. Do not use the
large arrow against the stops. It should only be used to bring the valve o
ff
the stops,
if needed. The speed of travel is about the same for both arrows and takes less than
a minute for a full stroke. The valve is at the end of its stroke when it quits moving as
indicated in the Poten ometer value in the Diagnos c Window. Con

rm the end of
the stroke by moving o
ff
and then back on to the mechanical stop.
