Airflow Alert; Resetting The Airflow Alert System - Labconco Cell Logic+ B2 User Manual

Airflow Alert

While the blower is on, any sudden disruption to the airflow within the cabinet will trigger
an Airflow Alert. When an Airflow Alert activates, the display will automatically change
(Figure 6-22), and the audible alert tone will sound.
The most common causes of an Airflow Alert are:
• Blockage of the inlet grilles
• Removal of the work surface or grille during
operation
Look to identify the cause of the airflow disruption, and
remove the blockage or return the work surface to its
proper position.
When a blockage of the airflow occurs, the cabinet's blower automatically increases its
speed to maintain constant volume airflow. This is a protective feature; however, if the
disruption is significant (for example blocking the entire front grille) it will not guarantee
product or personnel protection remains during the significant blockage event.

Resetting the Airflow Alert System

The Airflow Alert automatically dismisses once the motor speed has stabilized.
Note: Once the blockage or disruption has been resolved, the Airflow Alert may
reactivate while the blower returns to correct operating speed. It will dismiss
automatically once the blower reaches correct operating speed.
