NOTE: If the Supply Air setpoint is greater than the Cool setpoint, the cooling unit triggers an alarm and resets the Supply Air setpoint to equal the Cool setpoint.

•Fan Spd: Set the fan speed preference that will give you the desired temperature difference (DT). Each fan speed provides an approximate DT between the supply air from the Rack PDU and the air returned from the rack.

–Low = 16.7°C (30°F) DT (60% of maximum fan speed)

–Med-Low = 13.9°C (25°F) DT (70% of maximum fan speed)

–Med = 11.1°C (20°F) DT (80% of maximum fan speed)

–Med-High = 6.3°C (15°F) DT (90% of maximum fan speed)

–High = 5.6°C (10°F) DT (100% of maximum fan speed)

NOTE: The cooling group will automatically override this fan speed setting and adjust the fan speed to provide optimum cooling for the environment as needed.

The Proportional plus Integral plus Derivative (PID) loop controls the output of the fans.

NOTE: All changes to settings must be performed by qualified personnel.

Gain (P): The proportional multiplier (gain) for this mode or actuator. The proportional multiplier adjusts for the difference (error) between the measured value and the setpoint.

Rate (I): The integral multiplier (reset rate) for this mode or actuator. The integral multiplier adjusts for error measurement and the amount of time that the error has existed. The integral multiplier adds to or subtracts from the output in small increments to correct for the offset error caused by the proportional contribution.

Deriv (D): The derivative multiplier (derivative) for this mode or actuator. The derivative multiplier adjusts the output for rapid changes in the error, correcting for the rate of change of the error over time.
