ATTENTION: A value of zero in set-output words does not
necessarily correspond to zero pressure or flow. If you have
configured jumper E11, E12, E15, and/or E16 for bi-directional
valve operation, an output of 0% gives –10V dc, 50% gives
0V dc. Amplifier electronics or spool-null offsets may also
allow pressure or flow at zero volts signal input. Consult your
valve and amplifier specifications for more details.
Enter values for all Unselected Valve Set-outputs that are representative of
the signal output percentages required to drive the unselected valves during
the respective profiles. The valve spanning procedures presented in
chapter 9 require that your unselected valves be driven by a signal level
similar to how they are set during a normal production run. A detailed
discussion of this type of setpoint is presented in chapter 10 to highlight
the process considerations that impend modification of these parameters.
