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

* Magnetostrictive technology eliminating levers and switches
* Non contact and non wearing titanium float
* User friendly controller with easy to read parameters/alarms
* Uses single phase power to a central connection point
* Controller uses plug-in connectors for easy exchange
* Can be used for on/off pump operation or modulating fee

Safety

*
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!
