“Ultra Feathering Operation” Electronic Modules
UFO Electronics Provide Precise Proportional Control
The OEM Electronic board can either be used to enhance the operation of our line of controllers or as stand-alone modules. Standard features of UFO electronics include:

Pulse Width ModulationThe pulse width modulated output helps overcome the effects of hysteresis, stiction, hydraulic pressures, and mechanical tolerances that inhibit the operation of proportional electrohydraulic valves and strokers.
Threshold Adjustment & Maximum Output Adjustment- The threshold eliminates "dead band" in valve response at the start of handle travel. Maximum output utilizes the full handle travel regardless of the maximum output limit setting. Together they provide total proportional control over the entire control handle travel.
Diagnostic Light Emitting Diodes- These indicators simplify troubleshooting of the control circuit without the use of external equipment by indicating the presence of controller output. They can be used to differentiate between a fault that has occurred in the valve, valve coil wiring,or the controller itself: if the LED’s light up, indicating an output from the controller, then check the wiring down the line or valves.
High Current - Electrohydraulic valves that require more current than 2 amperes at 12VDC (1 ampere at 24VDC) use our High Current U.F.O. circuit board with a maximum output of 4 amperes at 12VDC (2 amperes @ 24VDC).

Options

Dual Range Feature– provides two different output ranges that can be pre-set and then selected by opening or closing a contact, manually or automatically, via the equipment being controlled. A typical application consists of using complete handle movements when operating equipment under critical conditions requiring slow, precise actions.

IRS (Integrated Ramp System)– is an adjustable ramping circuit that ensures smooth hydraulic system response. The ramp circuit limits the rate of change of the output to the set limits, eliminating the jerky response normally associated with quick handle movements. If the handle is moved faster than the set "ramp" rate, the change in the valve output will be automatically limited to the set "ramp" rate.

Ramp Thru Off– is an additional option using the IRS circuit. If the handle is abruptly returned to neutral (OFF), the output will automatically "ramp" down to the off position. The "ramp" rate is factory set to 2 seconds unless otherwise specified.

Dual Maximum Output– this feature provides separate maximum output limits in each direction of handle travel. This adjustment can be used to compensate for the imbalance of output in each direction that can be characteristic of some hydraulic circuits. It can also be used to purposely create an imbalance in output. For example, when maximum forward speed is required, but a limited reverse speed is necessary.

Warning

It is the purchaser’s responsibility to determine the suitability of any OEM Controls product for an intended application, and to insure that it is installed and guarded in accordance with all federal, state, local and private safety and health regulations, codes and standards.

Due to the unlimited variety of machines, vehicles and equipment on which our controls are used, and the numerous standards which are frequently the subject of varying interpretation, it is impossible for OEM Controls personnel to provide expert advice regarding the suitability of a given controller for a specific application. The flexibility of our products allows us to offer thousands of custom configurations. We can advise you of the various features that are available and you can examine models to see what meets your needs. We believe our customers’ engineering departments should be the qualified experts in their own product field. If the product will be used in a safety critical application, the customer must undertake appropriate testing and evaluation to prevent injury to the ultimate user.

Should you have any questions or if any of the above warning is unclear, please contact OEM Controls at 10 Controls Drive, Shelton, CT 06484, FAX: 203.929.3867, TEL: 203.929.8431.
