Cleaver-Brooks Hawk

Hawk ICS

The CB Hawk ICS is a totally integrated control system embodying precise boiler/burner management control and safety with logic based ancillary devices and functions. The result is a coordinated system which maximizes efficiency, reduces operating costs, and increases productivity; delivering critical real time and historic information with the touch of a screen! Using today’s state of the art technology, the CB Hawk ICS soars to a new level, combining a highly powered high speed processor with sophisticated inter-communication protocol (“Ethernet/IP”) for controlling and monitoring all of the important boiler system operating and safety functions in one synergistic, expandable package.

Key features and functions in base package:

• Integrated burner management control from pre-purge to post-purge.
• Flame scanning and amplifying. Processing inputs from solid state sensors measuring pressure and/or temperature.
• Firing rate control
• Thermal shock protection
• Night/day setback
• Outdoor reset
• Remote setpoint
• Lead/lag control for multiple boilers (option)
• Variable Speed Drive (VSD) capability for combustion air and/or boiler feed pump(s)
• Auxiliary inputs available for monitoring boiler related devices and conditions.
• Human machine Interface (HMI) for setting operating conditions and accessing all operating parameters and alarm history. All this with the touch of a screen!
• Local electronic communication

Monitoring Capabilities Include:

• Operating parameters, faults and selected I/O’s
• Stack temperature
• Combustion air temperature
• Combustion fan RPM
• Combustion air pressure
• Efficiency
• O2
• Steam pressure and flow
• Water temperature
• Fuel flow
• Water level
• Firing rate
• Faults and fault history

Optional Features and functions include:

• Parallel control of fuel and air using motor actuator drives; minimizing linkages.
• Water level monitoring and alarming
• O2 monitoring and/or trimming
• Ethernet and internet communication
• E-mailing, paging and on-line trouble shooting
• Building management system interfacing
• Backlit touch screen (optional)

LevelMaster

The basis of design called for use of a microprocessor based control system which embraced six (6) important design criteria: Simplicity, Safety, Security, Dependability, Adaptability and Environment. The result is the revolutionary C-B Level Master low water cutoff and pump control using the proven magnetostrictive technology (used for many years in various industries for measuring level and distance relationships) in conjunction with a solid state sensor and microprocessor based controller.

Simplicity

• Column blowdown reminders and message it’s been done properly or improperly
• System allows for checking the auxiliary low water cutoff and its proper operation
• Float movement is constantly checked; stuck float shuts boiler down
• Electrics and microprocessor circuits checked several times per second for continuity and performance
• Low water shutdown and alarming
• High and low water warnings
• Alarm and blowdown history logging with time and date stamps

Security

• Password protected regarding level settings and alarm and blowdown history files
• On going level indication; easy to see and read exactly

Dependability

• Alarm and blowdown history logging
• Blowdown reminders
• Constant checking of electrics/electronics
• Remote communication access (RS-232)

Adaptability

• Direct replacement and retrofittable to all makes of boilers
• On/off or modulating boiler feed control with same unit

Environment

• C-B Level Master eliminates the mercury!
