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.
RUN MODE, NORMAL
FUNCTIONS OFF
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.

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
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.
Threshold, Max Out and Low Range adjustments are made in 0.5 % steps.
Ramp Up sets the time the machine’s function will take to increase (accelerate) from off to full on. This adjustment is made in tenths of a second. Ramp Down sets the time required for the 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. FREQUENCY 1 2
