8.2.4 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.
To verify or alter any of the airflow setpoints or alarm limits, press the menu setpoints/limits menu item. Then,
press any of the individual setpoints or alarm limits to verify and/or change. Press UP or DOWN to change new
value. Press SAVE to enter new value.
