The OUTPUT LED flashes when any of the PWM outputs are active. It will turn off when all of the
outputs are off (this may take several seconds if a long Ramp Down time is used). If the output LED is on
continuously (not flashing) then one of the 8 PWM outputs is shorted to ground. Operate one joystick at a
time while observing this LED to determine the output. Then check the wiring and correct the short circuit.
Optimizer Diagnostics
The Optimizer can be used for system testing and troubleshooting. When the
Optimizer is plugged into the Superflex, it will start by displaying the “RUN”
screen. If the display is blank, then check the power and ground wires to the
Optimizer. If the display looks like the example shown here, there is a
communication problem between the Superflex 4 Controller and
the Optimizer. This is most likely a connector or wiring problem.
Digisensor operation may be checked by using one of the diagnostic menu displays. Press the Optimizer’s
MENU key, and then press the ENTER key several times, until the display’s top line reads “DS1 DS2 DS3
DS4”. Below each of these indicators is the actual data being sent by a particular Digisensor. By moving
the joystick handle, the data will change.
The displayed Digisensor data will decrease to 0 when the joystick is moved in the “A” direction
(Digisensor potentiometer shaft rotates counterclockwise). Likewise, the displayed data will increase to
511 when the joystick handle is moved in the “B” direction (Digisensor shaft rotates clockwise). When the
joystick is centered, the Optimizer’s data will be approximately 255.
Four digital inputs can be tested (see figure17).
Press the Optimizer’s MENU key and then press
the ENTER key several times to reach this menu
item. Then observe the Optimizer display while
operating the machine controls that correspond to
these inputs. A “1” is displayed when the input is
at a high voltage ( at least 10 volts ) or “on”. A
“0” is displayed when the input is at ground or
“off”.
