2.3 Alarm and Warnings
The warning AIR FAIL! indicates that there is airflow failure. The operator should check if there is any
obstruction to the airflow, and correct it if possible. However, if the problem continues, the operator should
stop working as the hood’s protection may have been compromised. Call service or Esco’s local distributor.
Other alarms that indicate a failure or an error in the BSC system:
‐ ERR.AIRFAIL will be displayed if the blower is turned off while there is an airflow failure.
‐ ERR.CALIB will be displayed if the airflow velocity sensor is not yet calibrated.
