TROUBLESHOOTING
Electrical Shock Hazard.
RISQUE D'ÉLECTROCUTION.
Risk of fire, electric shock, or injury to persons during cleaning and user-maintenance! Disconnect the
appliance from the power supply and alow sufficient time for electrical discharge before servicing.
Risque d'incendie, de choc électrique ou de blessures lors du nettoyage et de l'entretien par l'utilisateur!
Débranchez l'appareil de l'alimentation et de soins permettra suffisamment de temps pour la décharge
électrique avant l'entretien.
Before servicing or cleaning unit, switch power off at the service panel and lock the service disconnecting means to
prevent power from being switched on accidentally.
Avant de réparer ou de nettoyer l'appareil, coupez l'alimentation électrique au panneau de service et bloquez les
dispositifs de sectionnement pour éviter une mise en marche accidentelle.
When service or replacement of a component in the fan requires the removal or disconnection of a safety device, the
safety device is to be reinstalled or remounted as previously installed.
Lorsque le service ou le remplacement d'un composant dans le ventilateur nécessite le retrait ou la déconnexion d'un
dispositif de sécurité, le dispositif de sécurité doit être réinstallé ou remonté comme précédemment installé.
1. Fan shakes while in use.
Shaking may be caused by a variety of problems, such as installing the fan in an open-sided structure causing a draft.
In this case it may be necessary to secure additional restraints. Check the torque on all fasteners by using a calibrated
torque wrench, DO NOT loosen and re-torque fasteners. If problem persists, please call the factory for assistance.
Although unlikely, mechanical resonance vibration is a possibility. In such case, contact factory for programming
adjustments.
2. Fan will not start.
Ensure that the orange indicator LED is blinking. If the drive powers on but the fan still will not start, switch the VFD
disconnect to "OFF" and check that the leads going to the motor are secured and connected properly. Double check
the provided wiring diagram for controller wiring also. If the problem persists, have a qualified electrician troubleshoot
the wiring.
3. Fan rotates in the wrong direction.
The fan should rotate in a counterclockwise direction when viewed from below. If this is not the case, ensure that
both the controller and remote switch box are wired correctly.
4. The fan controller makes radio frequency (RF) noise.
The fan controller can generate RF noise in many ways, but this noise can be prevented by following the proper
wiring practices outlined in the "Electrical Installation" section.
a. Ensure proper grounding at the motor, controller, and from the controller to the supply.
b. Do not run your controller and sensitive equipment on the same power line.
c. Install properly sized EM/RFI filter.
d. Contact Customer Service at 1-800-961-7370.
5. LED indicator is not blinking in normal fashion.
Please contact S&P customer service to resolve issue.
