The Sash Position approach represents a widely accepted method designed to control face velocity base on calculations configured directly into the controller. Face velocity is controlled by calculating the flow area based on sash position and then controlling a calibrated air valve.

Secondary air flow feedback is also possible. The Sash Position method uses polymer coated string pots, a linear airflow valve, and a differential pressure switch to regulate face velocity.

The NB-GPCFHC in combination with the FHC-SD color touch-screen Local User Interface offers unprecedented technology combined with flexibility of control found nowhere else in the industry today.

These controllers offer the maximum in control power, flexibility and speed based on a 32 bit processor with a real time operating system. They employ one of the most complete Native BACnet implementations in the industry.

Flexibility is expanded through the use of the FHC-SD by offering multiple levels of configurability and accesibility designed to give users security and safety on a highly visible, live local user interface. The FHC-SD allows for two-staged alarming, notifying users of a potential problem through visual and audible alarms.

Should a cautionary preset “low/high-limit” be reached, the display will begin to flash yellow and emit a 3 second pulsing alarm from the display as a caution to the hood operator. Should an extreme "low/high-limit" alarm occur, the display then will go into emergency override, displaying a red flashing background and emitting a constant pitch alarm from the display, while driving the damper or valve to a preconfigured position.

A separate emergency touch screen icon can be operator activated, forcing the controller to activate the preset emergency procedure; which may also include audible and visual alarms through the Native BACnet network.

• Native BACnet control utilizing American Auto-Matrix state of the art GPC technology

• Complies with ASHRAE Standard 110-1995

• 32-bit microprocessor utilizing tunable high-speed PID control algorithms

• PID control loop cycles every 50ms, for exhaust damper output

• I/O updated 20 times per second

• Stand-alone or network operation

• Reliable high-speed communication over twisted pair (EIA-485) wire, up to 115.2k baud

• Controls using measured face velocity or sash position

• Pre-programmed function blocks

• Configurable setpoints, multistage alarms, and alarm delays

• Separate Flow Totalization Network for multiple hood volumetric offset flow control of laboratories

• 18-bit input resolution enables various measured variable inputs (sash position, face / side wall velocity, hood static pressure)

• Emergency saving setback mode via sensor input or network

INTEGRATE WITH US OR THEM

The Auto-Flow critical environments architecture includes a robust family of controllers and peripheral devices. Our Native BACnet implementation is on of the most flexible and open in the controls industry.

There is no need for gateways to convert protocols to BACnet with the control architecture, as all controllers are Native BACnet. There are several ways that an Auto-Flow system can be integrated to other systems. It can interface directly via BACnet to most building automation networks and utilize their GUI capabilities.

Moreover, by integrating with Aspect, a complete web-based frontend and data archiving system, a solution is created that can be independent of the installed BMS system or integrated with it. This approach has the further advantage of enabling an interface to Modbus energy measurement technologies.

American Auto-Matrix fume hood controllers, through their implementation of standard and non-standard control objects, make virtually every aspect of the contollers available within the BMS architecture. Any industry standard BACnet system that supports non-standard objects can interface with the control family over it's network.

These and other members of the GPC family are peer-to-peer controllers with the ability to share values and information among each other on the BACnet network.

Pressure offset control schemes can be easily implemented in the laboratory controller as can flow offset logic. In the case of the flow offset application, a dedicated cascade flow circuit is available to assure high-speed updates to this control loop independent of the BACnet network when multiple fume hoods are employed in a single laboratory.
