Compu-Spread Controllers Rexroth 420RC Solid Controller The 420RC controller is a closed loop controller incorporating many advanced features. The large easy to read display shows operating information as well as error status messages. Conveyor and spinner functions have 9 settings with integrated Blast, Pause, and Stationary Unload functions on the dials. Remote pause and blast functions are available with the controller, and are accessible through a detachable cable assembly. System setup and calibration is easily accomplished with on screen text defined parameters, and separate selection buttons. Vehicle speed and material calibration are easily set with on screen setup prompts. Error messages are text defined, and accompanied with an audible alarm indicator.

More information >> Rexroth 440 Solid and Liquid Controller The latest in closed loop spreader technology, the Rexroth 440RC controller incorporates a multi rate closed loop solid and liquid application selector. This latest generation of controller incorporates a large VFD graphics display screen for easy operator reference, providing full access to spreader rate and system status information at a glance. System setup is accomplished through easy to use advanced PC based configuration software, which can be transferred to the Rexroth 440RC controller through an infra red Palm Pilot® link. System setup can be accomplished in minutes with a conventional laptop computer, which displays all operating parameters in logical groups, and in full text format. The infra red link allows easy controller access in the field for system setup and logged data retrieval. The system can also be easily accessed on the vehicle with easy to follow on - screen instructions. The Rexroth 440RC controller also features auto-nulling of all proportional outputs, and auto calibration of materials. The addition of a closed loop gate function ensures maximum conveyor efficiency for any gate setting, resulting in optimum accuracy for all spread rates and ground speeds. Automatic reduction of the solid application rate is also available when using the pre-wet system, resulting in further material savings. Material compensation based on road temperature read-out has also been incorporated. The Rexroth 440RC controller is designed on a modular platform, setting a new standard in spreader control systems. More information >> Rexroth 425RC Solid Controller The 425RC has all the features of the 420RC controller with the addition of a proportional joystick and 2 auxiliary switch functions. The 425RC is ideally suited for compact vehicle interiors and applications where a joystick and spreader controller is required. The proportional joystick has a 4 axis capability, and the console has 2 status indicators for modes. A deadman switch on the joystick handle prevents accidental activation of a function. The spreader section controls the spinner and conveyor based on vehicle speed and conveyor feedback. Or the unit can be operated as a manual or open loop controller. Joystick nulling and spreader calibration are performed on screen making setup quick and easy. More information >> Contact us by email >> Return to Compu-Spread main page >>
