Model HAWK ADAC Advanced Deaerator Control HAWK ADAC ADVANCED DEAERATOR CONTROL The CB ADAC Advanced Deaerator Control provides a PLC based control system for a deaerator, surge tank, two tank deaerator-and-surge, or Duo-tank installations. The system is capable of controlling operation of boiler feed and/or transfer pumps, maintaining tank levels, monitoring and responding to system demands, and recording/annunciating alarm conditions. The ADAC can run as a stand-alone system or connect to a CB-HAWK Master Panel or customer building automation system for monitoring purposes. FEATURES AND BENEFITS Standard Features: • Integration of various deaerator and surge tank devices in a common control system • Touch screen graphical Human Machine Interface (HMI) • Deaerator and surge tank water level modulating controls • Basic Chemical feed pump control • Boiler feed pump control - up to 6 pumps via variable speed drive, soft starters, combination starters, or contactors • Surge tank feed pump control (transfer pumps) - up to 3 pumps • Pump alternating, lead/lag, and automatic rotation • Serial, Ethernet, BAS, web server communications capability • Control of remote devices (valves, etc.) • Alarm/fault annunciation and history with audible alarm • Red/Yellow/Green stack light for visual status indication • Resettable Cumulative pump run time totals for maintenance purposes Optional Features: • 10” PanelView Plus in lieu of 7” (10” is standard on two tank systems) Section D05-1 Rev. 03-11

Model HAWK ADAC Advanced Deaerator Control 4. An optional Surge tank MUV biasing mode is available. A bias may be enabled (user defined) to force the primary MUV feeding the DA tank to close as level falls in the surge tank. The bias factor applied to the primary MUV position increases as the level in the surge tank gets lower. This prevents the surge tank from pumping down to low water cutout so it can continue to run while condensate is returned to it. You would then have the secondary valve plumbed to the DA from a separate source and add water to the DA to be heated, deaerated and sent...

Model HAWK ADAC 2.7 Advanced Deaerator Control ADDITIONAL ADAC SYSTEM FUNCTIONS: A. A pressure sensor mounted in steam space monitors Deaerator pressure. B. A set of contacts on each pump’s overload relay provides indication of pump failure. If VSDs or soft starters are used, a fault contact is monitored by the PLC to indicate pump failure. C. A set of contacts on each pump starter indicates pump running. If VSDs or soft starters are used, a contact is monitored by the PLC to indicate run status. D. A selector switch is mounted at each pump starter to allow Hand- Off-Auto switching. ‘Hand’...

Model HAWK ADAC Advanced Deaerator Control 2. Data can be transferred by Ethernet through a CB Master Panel to a customer BAS. If a Master Panel is unavailable, the protocol translator can be configured to communicate directly between the ADAC and the customer BAS. Section D05-9 Rev. 03-11
