Description

The APOGEE

Automation System Laboratory Room

Controllers and Room Pressurization Controllers are

available on a new hardware platform. The Lab

Controller Module (LCM) uses the Off-board Air

Module (OAM) to measure airflow for standard and

custom pressurized room control applications.

Lab Controller Module

The LCM (Figure 1) operates as an independent,

stand-alone DDC controller and can be connected on

the Floor Level Network (FLN) with the APOGEE

Automation System. The LCM includes the largest

physical point count of any APOGEE FLN device. Not

all physical points are used in all applications.

Off-board Air Module

The OAM (Figure 2) contains the air velocity sensor

(a specialized differential pressure transducer), V/F

conversion circuitry and solenoid for auto-zero

function. Advanced digital signal processing produces

a highly accurate reading of even the noisiest flow

signals.

The auto-zero solenoid connects to the air velocity

pressure transducer's inlet ports to enable automatic

periodic re-calibration. This re-calibration ensures

accurate, drift-free airflow measurement. Automatic

re-calibration of the differential pressure transducers

occurs upon system power-up and when airflows are

stable with frequency selectable from 1 to 6 times a

day.
