Fan motor won’t start or won’t stay running.
Input circuit not operational.
Check input power to motor circuits for proper voltage on each phase.
Check and correct internal motor wiring for proper connections based on the incoming line voltage. Wiring diagram is found on lead access plate. Check for proper motor starter overload rating against full load amps on the motor nameplate. Adjust or replace overloads as required. Ensure drum is properly sealed against drum lid package. Ensure drum lid package is properly installed.
Improper electrical wiring.
Starter overloads are tripped.
Cone discharge is open to atmosphere.
Correct the rotation. See Section 5.1 “Start - Up.”
Fan rotation is backwards.
Check motor current draw and close fan or silencer dampers until amperage draw is below full load amp rating of the motor.
Fan damper is not properly adjusted.
Dust Emissions from clean air discharge.
Storage container is full.
Inspect and empty container as required.
Leak in drum lid hose (drum models only).
Use a test cigarette and check for pinhole leak in hose. Replace if required. If the fan is not rotating in the correct direction see Section 5.1 “Start - Up” to reverse the rotation.
Insufficient airflow.
Fan rotation is backwards.
Loose or open access door.
Tighten access door and drum lid connection.
Duct damper(s) or system damper is not positioned properly.
Adjust dampers to allow for sufficient air volume.
Air inlet(s) obstructed.
Inspect and clean all hoods or other machine connections.
Large leak in storage container.
Check for a large leak in the storage compartment or container. In 55 gallon drum applications, make sure the drum is under the drum lid and sealed. On hopper models, make sure the slide gate is closed if the hopper does not have a drum connection Check for obstructions in the ductwork or the exhaust. Check ducts and hoods for improper sizing.
Plugged ductwork.
Leaks in ductwork.
Check for loose, leaky joints in the ductwork. Fix or replace as required.
