Built on the tradition of excellence in stationary gas engine airfuel ratio control first established by the EPC-series product line, Altronic’s AFR-500 Advanced Air-Fuel Control System has been engineered and built to provide a new level of scalability, reliability and value to operators and users globally. This innovative new system can be deployed on carbureted engines in both single regulator (one AFR-500 module) and dual regulator configurations (using two AFR-500 modules). The 24VDC-powered AFR-500 module (below) is designed to be DIN-rail mounted in a control panel or other suitable enclosure on both new and existing installations. In addition to on-board temperature protection, analog and digital control inputs, and advanced control setpoint mapping, the AFR-500 operates using modern, field-proven UEGO (wide-band) exhaust sensor. Addressing specific field requirements in managing frequent and substantial changes in engine load and fuel gas btu levels, the system is engineered to offer rapid and precise control of existing Altronic EPC-series stepper motor-based control valves, the Altronic AGV-5 fuel control actuator, and many other third-party 4-20mA- compatible devices. Standard 8" and 15" HMI displays are available through the integration of the optional ACM-4000 Altronic Computing Module. AFR-500 is built with simple configuration and system networking in mind. Full Ethernet and ModBus TCP compatibility provides full access to the configuration and operation of the system. Utilizing the same web browser-based approach incorporated into the DE-4000 the AFR-500 can easily accessed from a PC or other similar device using the on-board Ethernet port. This high level of connectivity also allows for its full integration as an add-on module for a DE-4000 Next-Generation Safety Shutdown and Control System. The AFR-500 system is suitable for use in Class I, Division 2, Group C and D hazardous areas.
