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 operate d, 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 toggl es

(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 on e of the 4 channels for

adjusting. This key only operates when all controlle rs

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 adjustme nt. The “value” is

flashing (blinking on and off) and will cha nge as the

Plus or Minus keys are pressed. The Channel

(Function) and Direction a re displayed generically on

the bottom line, and as the actual machine’s function s

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 represe nts 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 operat e 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.
