Original instructions
Alarm Screens
Sash is too high
The sash is open too far for safe operation.
Airflow Alert
The airflow patterns in the cabinet have changed,
resulting in a sudden change in the 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 while the cabinet is in
operation.
Inflow Alarm
The inflow has dropped below safe levels. Press
the “Blower” button to reset the operation of the
Logic+. If the alarm activates frequently, it is likely
due to unstable exhaust system airflow, or to an
excessively blocked Exhaust HEPA filter.
System Error
The motor and display circuit board are not
communicating properly. DO NOT USE THE
CABINET UNTIL THE PROBLEM HAS BEEN
CORRECTED.
