7.5.2.2 Setpoints/Limits
The airflow setpoints and alarm limits may also be verified or altered. Typically, these default values are
factory set based on the cabinet type, model and size as previously discussed. However, they may be altered
in special cases for modified cabinets. The setpoint establishes the airflow values that are to be maintained.
The high low limits establish the alarm boundaries from the nominal setpoint. The default values have been
established based upon the performance specifications and cabinet component tolerances.
Entry into the setpoints/limits functions requires a service password for entry. The default password is “9876”
