Glossary

English units

The foot-pound-second system of units for weights and measurements.

equipment controller

A FLN device which provides additional point capacity to a field panel or provides DDC to individual room or mechanical equipment control. The FHC is a specialized equipment controller.

field panel

A device containing a microprocessor for centralized control of system components and equipment controllers. A field panel samples and processes field data, initiates control actions, communicates with its operators, and generates reports, displays and warnings.

FLN

Field Level Network (formerly known Floor Level Network).

Fume Hood Controller

Multi-application equipment controller designed to provide Direct Digital Control) for various types of Variable Air Volume (VAV) fume hoods. The controller consists of a controller board and a controller enclosure.

intercept

Factor which converts analog values (used by the controller) to a form which the user can understand (engineering units). Slope and intercept constants are determined by the type of field input/output represented by the physical or virtual point.

loopout

Output of the control loop expressed as a percentage.

LPS

Liters Per Second.

OCC mode

OCCupied mode.

OFF text

Text indicating the de-energized state of a digital point (for example, OFF, CLOSED, NO).
