Alarm Screens
Sash is too high
The sash is open too far for safe operation.
Airflow Alerts
The airflow patterns in the cabinet have changed, resulting
in a sudden change in either motor speed. This is most likely
due to a blockage of the grille or the exhaust filter outlet. It
may also be caused by removal of the work surface(s) while
the cabinet is in operation.
Exhaust Fan Alarm
There has been a failure of the exhaust fan, or its
communication to the cabinet’s control board. DO NOT USE
THE CABINET UNTIL THE PROBLEM HAS BEEN
CORRECTED.
Exhaust System Alarm-Active Protection Mode
When connected to an exhaust system, and the flow drops
below acceptable limits, this screen will appear. When the
timer reaches 0, the supply blower will shut off, and the
exhaust fan will continue to operate for 10 more seconds,
protecting the operator.
Exhaust System Alarm
After the countdown reaches 0, the exhaust fan will shut off
and this screen will be displayed. If this alarm is displayed,
the Axiom blower will need to be turned off, and then back
on again to reset the alarm. Frequent Exhaust System
Alarms indicate unstable or insufficient exhaust flow, and
must be corrected.
System Error
The motors and display circuit board are not communicating
properly. DO NOT USE THE CABINET UNTIL THE PROBLEM
HAS BEEN CORRECTED.
