HAWK INTEGRATED BOILER CONTROL SYSTEM - 1

Model HAWK Integrated Boiler Control System HAWK INTEGRATED BOILER CONTROL SYSTEM The HAWK is a state-of-the-art boiler control system that integrates the functions of a Programmable Controller and Burner Management Controller, as well as other boiler operating and ancillary controls. The HAWK system incorporates a graphical Human Machine Interface (HMI), which displays boiler parameters, fault annunciation and alarm history, as well as providing access to boiler configuration and control functions. The HAWK system includes complete boiler firing rate controls for steam or hot water boilers. The HAWK’s advanced technology features utilize the latest communication methods, such as Modbus, Ethernet, and the Internet. The HAWK also has the capability of interfacing with various building/plant automation systems. Additional features include lead/lag capability; e-mailing and paging of alarms, remote monitoring, and HMI alarm history printing. The HAWK Integrated Control System may be used on most types of steam or hot water boilers, including firetube, industrial watertube, and commercial watertube. It is designed to operate with a gas, oil, or combination burner using a single-point modulating control or a parallel-positioning fuel-air ratio control system. In addition to installation on new boilers, the HAWK can be added as a retrofit to existing boilers. Contact your local authorized Cleaver-Brooks representative for details. The HAWK system is offered in Advanced, Intermediate, and Base packages. Table D-1 shows a feature comparison. FEATURES AND BENEFITS Advanced Technology Standard Features: • Integrates control function of burner sequencing and safety with firing rate, fuelair ratio, and operating limit controls • Incorporates a programmable controller • Touch screen graphical human machine interface (HMI) • Monitors and displays connected boiler parameters • Optimizes boiler firing rate control • Alarm/fault indication and history • On-screen fault diagnostics • Built-in two boiler lead/lag control • Night/day setback control • Thermal shock protection • Remote modulation • Remote setpoint • Assured low fire cut-off • Assured start permissive safety interlocking Section D02-1 Rev. 09-09
