6.1.1 Overview
The Aeromax™ control system is designed to service the control requirements of the LabGard® ES NU-813 CVE.
The Aeromax™ control system consists of an electronic module that will perform the following functions:
•
Easy user interface via LED’s and function keys
•
Control blower via solid state switch.
• Control lights via solid state switch.
• Hinged window alarm
• Disable audible alarm switch with ring back function.
• Control blower DC EC Impeller with solid-state DC Motor Controller that provides automatic
compensation for line voltage variances.
•
Monitor and display airflow system performance via PresurFlow™ monitor.
The LabGard® ES NU-813 offers the latest digital microprocessor design technology for improved CVE performance
and safety. The Aeromax™ control system integrates a digital pressure sensor (PresurFlow™) to monitor the CVE
airflow performance. The Aeromax™ control system also integrates a DC EC Impeller controller that provides
automatic compensation for both filter loading and line voltage variances. There is additional on/off control of
blower and light. Lastly the Aeromax™ control system monitors the hinged window position with a micro switch.
All the above functions are shown in a system block diagram (see figure 1).
