OEM Controls Superflex 4 - Manual (Page 11)

The Menu key accesses
less frequently used items,
other information and
diagnostics. A “three key
menu” system allows
additional functions and
features to be easily added
to SF4 while still having a
universal Optimizer. The
Enter key is used to step
through the various menu
items. The section
“Diagnostic Menus” below
describes the Menu and
Enter key functions.
The Plus and Minus keys
are used for changing the
various adjustments
(threshold, ramp, etc.).
The process is described
below. The Run key must
be pressed after making an
adjustment so the new
value is saved.
Figure 14 identifies various items that are displayed
when you are making an adjustment. The “value” is
flashing (blinking on and off) and will change as the
Plus or Minus keys are pressed. The Channel
(Function) and Direction are displayed generically on
the bottom line, and as the actual machine’s functions
on the top line. The parameter being adjusted (in this
example threshold) is shown at the upper left.
CAUTION - Be sure to press the RUN key after
making an adjustment or the new setting will be lost
Adjustments
Threshold is the amount of output that causes the machine to just start to move or operate. The Threshold
value represents a PWM percent duty cycle, which corresponds to the initial voltage signal driving the valve
when the Joystick handle is moved slightly from its off position.
Max Out or maximum output is the amount of output that causes the machine to operate at maximum
desired speed. The Max Out value also represents a percent duty cycle, corresponding to the voltage signal
driving the valve when the Joystick handle is fully deflected (and high range is selected).
Low Range sets the limited amount of output signal when the Joystick handle is fully deflected. The Low
ange setting represents a percentage of the Maximum Output value.
