Optimizer

The OPT4 Optimizer is a hand held user
interface with a keypad and an alphanumeric
display. It is used as a calibration and diagnostic
tool, to display various system values, and to
make adjustments to the SB family of controllers.

When a joystick is operated, the Optimizer
display will change to this. The upper right
portion identifies the active channel or function,
and the lower right portion indicates the actual
output value. In this example, function 1
direction B (Fn1B) is active, with an output PWM
duty cycle of 72.5%. This channel has been
customized to read “Rotate Left”. As the joystick
is moved, the displayed value will change. If
more than one joystick is operated at the same
time, so that several outputs are active, the
Optimizer display will show the channel who’s
joystick was most recently moved.

RUN MODE, NORMAL
FUNCTIONS OFF

RUN: ROTATE L
Fn1B 72.5%

There are five adjustment select keys - Threshold,
Maxout, Low Range, Ramp Up and Ramp Down.
These keys are used to select one of these 5
parameters to adjust.The Direction Select key toggles
(alternates between) the A and B direction. This key
only functions when all joystick controllers are off. The
Optimizer automatically selects the direction when a
joystick is operated; this makes active adjustments easy
to perform.

The Function Select chooses one of the 4 channels for
adjusting. This key only operates when all controllers
are off. Each time this key is pressed, the next function
(or channel) is selected, that is 1 ... 2 ... 3 ... 4 ... 1 ...
etc. The Optimizer automatically selects the function
(channel) whenever a joystick is operated, making
active adjustments easy to perform.

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

FRONT

Adjustments

Threshold
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
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
signal when the Joystick handle is fully deflected.
The Low ange setting represents a percentage of
the Maximum Output value.
Threshold, Max Out and Low Range adjustments
are made in 0.5 % steps.
Ramp Up
take to increase (accelerate) from off to full on.
This adjustment is made in tenths of a second.
Ramp Down
machine’s function to decrease (decelerate) from
full on to off. Ramp Down adjustments are also in
tenths of a second.

Diagnostic Menus

Various pieces of information are available in the
Diagnostic Menu mode. This mode is started by
pressing the “Menu” key. The Optimizer displays
the first menu item. Press the Enter key to step
through all of the menu items. The first four menu
items display fixed data. Two examples are
shown at the right.
The valve PWM frequency for the first two outputs
(channels 1 and 2) is followed by the valve
frequency for the second two outputs (channels 3
and 4). Next the OEM part number and serial
number are shown.

The next three menu items are active displays
showing input and output signals. These screens
are useful for troubleshooting. The switched
digital inputs (see figure15) can be tested on this
display. If an input is On, the display is a “1” and
if it is Off or 0 volts, the display is a “0”. Likewise
the AUX outputs and Digisensor inputs can be
displayed. The Troubleshooting guide has
additional information.The next menu item is
“Restore Factory Defaults” and is used to reset all
of the adjustable parameters to the settings that
were programmed in by the factory. The display
looks like this, with the bottom line flashing.
Pressing the Plus key will restore the default
values. Pressing the Enter key will step to the
next menu item.
The final three menu selections go together.
They provide an alternate method of choosing
adjustments, channels and the direction for
making changes.
At each of these
screens, the
selected
item (e.g.: TH, MX, RU, RD or LR) will flash. Use
the Plus key to select and the Enter key to go to
the next menu. After proceeding through these 3
menus, you will be able to adjust thE selected
variable.

Customized Display (Appendix 2)

Your particular Superflex 4 System application
may be customized to easily identify the
machine’s function. Nine characters may be
specified for each function, channel and direction.
For example - you might choose “DRIVE FWD”
for the machines drive forward, “BOOM LIFT”
and “ROTATE R” for boom functions, etc. Refer
to the customized data located in Appendix 2 of
this manual.

Bench / Static Adjustments

Any adjustment can be made without operating
the machine. This process is known as “static” or
“on the bench” calibration. Use the following
steps -

1) Provide power to the Superflex 4 Controller.
Connect the Optimizer.

2) Select a “function” (channel) by pressing the
Function Select key one or more times, until the
desired channel (1 through 4) is displayed.

3) Select a direction (A or B) by pressing the DIR
A/B key.

4) Select a controller adjustment by pressing one
of Threshold, Maxout, Low Range, Ramp Up or
Ramp Down keys.

5) Use the Plus and Minus keys to make the
adjustment.

6) Press RUN to save the changes before
powering down or disconnecting the
Optimizer.

Factory Default Values (Appendix 3)

All defaults (preset values) as well as upper and
lower limits to each adjustment range may be
specified by the customer. These setting are
installed by OEM Controls when your Superflex 4
Controller is manufactured. After making
adjustments with the Optimizer, it may be
desirable to return to these default values. This
task is easily accomplished with the Optimizer.

1) Apply power to the Superflex 4 Controller and
connect the Optimizer.

2) Press the Menu key. Then press the Enter key
several times, until the Optimizer displays
“Restore Defaults?”.
Press the Plus key to restore the default values.
The Optimizer displays “BUSY” while the original
values are copied. This may take several
seconds, depending on how many values need to
be restored. Then the Optimizer will momentarily
display “DONE” and return to the default run
screen. Be sure to wait
disconnecting the Optimizer or turning off power
to the Superflex 4 Controller. After all
adjustments have been made for the desired
machine performance, it would be helpful to
record all of these settings for future reference.
The table at the right can be used for this.
