SX Microcontroller

• BLN-95-9067-2
• Issue: October 2002

DESCRIPTION

• Danfoss SX microcontroller is an environmentally hardened device that is an ideal platform for mobile machine software applications such as hydrostatic transmission automotive control, closed loop speed control, engine load control, and leader-follower control.
• The SX consists of a circuit board assembly inside a rugged die-cast zinc housing. The controller can interface with a wide variety of input devices including potentiometers, Hall-effect sensors, pressure sensors, pulse pickups and encoders, and has output options that interface with high current proportional solenoid valves and low current pressure control pilot valves.
• Standard, preprogrammed application solution software, called Personalities, make the SX a cost effective solution for OEMs looking to replace analog controls or to introduce micro electronic controls on their machines. Personalities are available for most common machine control applications, isolating OEMs from the need to write application software code. Personalities are readily tailored to specific machines by changing application tuning parameters through the use of Danfoss set-up software.

FEATURES

• Robust electronics operates over a range of 9 to 32 volts with reverse battery, negative transient and load dump protection
• Environmentally hardened design including coated die cast zinc housing that withstands harsh mobile machine operating conditions including shock, vibration EMI/RFI, high pressure washdown, temperature and humidity extremes
• Compact footprint
• Motorola 8 bit MCH68HC908 microprocessor
• Versatile I / O—Hardware configurable inputs and outputs
• Standard Danfoss (4) LED configuration for diagnostics
• EEPROM memory allows factory shipment of pre-programmed the Personalities or field programming of engineered application software and tuning parameters
• The Kernel operating system facilitates application software transportability across Danfoss micro electronic platforms
• WebGPI user interface
• Optional CAN 2.0b-compatible network communication

APPLICATION SOFTWARE

• SX is designed to run Personalities or control solution software engineered for a specific machine. Consult
• Danfoss Minneapolis Customer Service for a list of available Personalities.

ORDERING AND REPAIR INFORMATION

• The SX ordering part number designates both hardware and

MACHINE WIRING GUIDELINES

1. All wires must be protected from mechanical abuse. Wire can be run in flexible metal or plastic conduits.
2. Use 85° C wire with abrasion resistant insulation. 105°C wire should be considered near hot surfaces.
3. Use 18 AWG wire.
4. Separate high current wires such as solenoids, lights, alternators or fuel pumps from control wires.
5. Run wires along the inside of, or close to, metal machine frame surfaces where possible. This simulates a shield which will minimize the effects of EMI/RFI radiation.
6. Do not run wires near sharp metal corners. Consider running the wire through a grommet when rounding a corner.
7. Do not run wires near hot machine members.
8. Provide strain relief for all wires.
9. Avoid running wires near moving or vibrating components.
10. Avoid long, unsupported wire spans.
11. All sensors and valve drive circuits have dedicated wired power sources and ground returns. They should be used.
12. Sensor lines should be twisted about one turn every 10 cm (4 inches).
13. It is better to use wire harness anchors that will allow wires to float with respect to the machine frame rather than rigid anchors.
