NU-437 (SERIES 60^) / 477 (A2)AIRFLOW CALIBRATION
NU-437 (SERIES 60^) / 477 (A2)AIRFLOW CALIBRATION
The DC-ECM System works like this:
1. AC voltage is applied directly to the DC motor’s control module
2. The motor control module (Microprocessor) converts the AC to DC for Internal electronics and to power the motor
3. In addition, there is a second electrical cable that goes from the Main Control Board’s speed controller DC output to the motor. This generates a pulse-width-modulation (PWM) 2.5 – 8 VDC control signal and returns an RPM feedback signal from the motor to the speed controller CKT.

Once the airflow calibration is complete – calibrate the FlowGard Airflow Monitor
1. Press and hold ( ) and ( ) arrow keys simultaneously for 3 seconds until the center green LED blinks.
2. Allow the Unit to run for a minimum of 2 minutes.
3. Press RESET Key to enter the nominal airflow value; the Green LED will stop blinking and display normally.
This sets the high/low alarm limits +/-0.13 w.g. from nominal. Reference the operation manual for the NU-437/477 for more in-depthinformation and calibration procedures. If you require help, or havequestions, contact NuAire’s Technical Support Depart.

1. Adjust slide plates and/or exhaust volume desired so average velocity measured in the center of the (3) test points of either side is between 150fpm (.76mps) and 550fpm (2.8mps)
2. Verify containment with the capture of smoke
3. Verify low exhaust alarm with loss of smoke capture with in 15 seconds
