CB-Hawk Replacement System

CB-Hawk Replacement

Known as Honeywell BCS-7700 and CB-Hawk systems, thousands of units have been installed since the early 90's. Over a year ago, honeywell abruptly stopped manufacturing system components and spare parts.

The Preferred Instruments CB-Hawk Replacement System, based on BurnerMate TS technology introduced in 2005, consists of: a programmable DCS, a Honeywell flame relay, and a touch-screen HMI. Existing wires, sensors, and control cabinets can be reused. The CB-Hawk Replacement System is made and supported in America. Preferred Instruments has been a supplier to the boiler industry since 1920. Preferred will provide technical support and spare parts for the Hawk Replacement System for as long as they are needed.

Preferred's Solution

Preferred has configured a BurnerMate TS system to be a wire-for-wire replacement for the CB Hawk system. Installation is simple.

  • Reuse over 20 devices and replace only 5 to help minimize the installation cost
  • Existing control panel, entrance box, control switches, flame scanner, and operating limits are reused
  • Existing solid state gas and oil pressure sensors can be reused for monitoring purposes
  • Replace Hawk sub-panel with Preferred sub-panel
  • Replace gas & oil pressure sensors with pressure switches
  • Replace steam pressure sensor with a pressure transmitter (or temperature transmitter for hot water boilers)
  • Install a new purge air flow switch
  • Replace mod motor with Preferred SM-15 servo actuator
  • Remove CB-Hawk keypad
  • Install the Preferred touch-screen display (Blockware is pre-programmed.)

Touch Screen Operator Terminal

  • 10 or 6 Inch Display Sizes - 10.4" TFT 256 color VGA 640 x 480 pixel LCD or 5.7" CSTN 256 Color QVGA 320 x 240 pixel LCD
  • Password Protection - user configurable options and parameters, external commissioning tools are not required
  • Real Time & Historical Trending - is a standard feature, optional extended data collection allows historical alarm and event data to be exported to MS Excel

Advanced External Communications

  • Intranet Network - Ethernet connection is available for Building Automation System (BAS), SCADA system or standard internet browser communication
  • Telephone Modem (optional) - allows communication to a remote user over standard analog telephone lines
  • RS-485 Modbus Interface - is available to communicate to an external flame safeguard that is existing or supplied by others

Advanced Communication

Communication

Internet, Web Site Access

A standard WEB Browser provides remote monitoring and operation. Custom Software is not required. Historical alarm and event data can be imported to spreadsheet applications such as MS Excel

Intranet Communication

The ethernet communication port is easily assigned an IP address and connected to a facility wide network. Remote monitoring, control and data collection is available via a standard WEB Browser. Building Automation Systems and SCADA Systems are interfaced via industry standard MODBUS Ethernet communication

Touch Screen Operator Interface Terminal

Monitor and control boiler operation, setpoints, and process data from one convenient display. Commissioning activities are laid out in an easy to follow step by step procedure, eliminating the need for knowledge of controller menus and programming languages

DCS-III Programmable Controller

The DCS-III, the processor that powers the Hawk replacement system, is a state-of-the-art boiler-focused programmable logic controller. The Hawk replacement system is pre-configured to be a direct replacement for obsoleted CB-Hawk and HW BCS 7700 controllers. However, additional functions such as Parallel Positioning Combustion Control, O2 Trim, or VSD operation can be configured.

Color TouchScreen Display

The BurnerMate TS gives you a complete control of your boiler room at your finger tips...

Flame Safeguard

The BurnerMate system is engineered to be in compliance with the latest Factory Mutual and NFPA 85 standards. The systems are manufactured, tested and labeled according to UL 508 standards.

HW FSG

A HoneyWell LM 7800 Flame Safeguard controller sequences the burner through purge, lightoff, main flame, and shudown. The DCS-III processor extracts information from the flame safeguard controlller. Interface to the flame safeguard controller and the DCS-III is through the TouchScreen display.
