7.5 Airflow Control System Setup and Calibration
Failure to calibrate airflow to the specified requirements may
result in unsafe conditions of performance (i.e. product and/or
personnel protection, noise and vibration)
7.5.1 General
The operation of the NU-560 cabinet requires that the setup and calibration procedures be performed in order to
certify or commission the cabinet for usage. The setup and calibration procedures performed ONLY BY THE
CABINET CERTIFIER ensure that cabinet's setpoints are verified and that the airflow monitor sensors are calibrated
to read the correct values. Press MENU to access Calibration/Service parameter.
Entry into the Calibration/Service functions requires a service password for entry. After pressing the
Calibration/Service menu item, a password screen will appear. The default password is “9876”.
Once the service password is entered, the Calibration/Service menu will appear. To exit, either press the menu or
home icon.
One additional feature for service technicians is to bypass the whole 2 minute warmup time. By pressing the word
warmup, the system will move directly to run. It is recommended that at least a minute of warmup time be
observed, so the airflows can stabilize at their setpoints to avoid an alarm condition.
