General Description
The Superflex 4 System consists of joysticks and a stand alone controller that electrically drives
electrohydraulic valves. Typical applications include operating crane booms, fire truck ladders, track
driven machines and other hydraulic equipment with electrohydraulic valves and pumps.
Superflex 4 Controller
The Superflex 4 Controller is a rugged, microprocessor controlled device that can directly operate four bi-
directional electrohydraulic valves. The Superflex 4 receives inputs from Digisensors, switches, and other
transducers, and converts these signals into proportional PWM outputs to drive the valves. Each output
signal may be independently fine-tuned and calibrated by using the hand held Optimizer.
Figure 1 shows a Superflex 4 Controller. The Superflex 4 has three 12 pin connectors for inputs, outputs,
and power / Optimizer connections. (Revision B and later Superflexes also have two 4 pin connectors).
The connectors are designated “BT1” to “BT5” throughout this manual. Three red LEDS provide the user
with status and diagnostic information. A user friendly label identifies the connectors and provides simple
troubleshooting information.
The Superflex 4 Controller is a versatile and flexible control device. It may be factory programmed by
OEM Controls Inc. to include many different options. A few examples of its flexibility include -
! "
Single or dual coil valves with PWM frequencies from 33 to 1000 Hz.
"
Single or dual axis joysticks. Arotrack drive (convert dual axis to left and right track drive).
"
Discrete digital inputs for High / Low ranges, start up interlocks, ramp disable shutdown, etc.
"
Auxiliary outputs (2) for dump valves, alarms, multiplexed output selection, etc.
"
Various “belly” curves to modify the joystick controller’s characteristics.
The Superflex 4 is supplied with factory default settings for the electrohydraulic valves used. However, the
customer may select other default values and adjustment limits. This factory programmed data allows the
Superflex 4 to be installed and ready to use as delivered from the factory. Please contact OEM Controls
Inc. for details on customizing the Superflex 4 Controller for your particular application.
