Operation
Ensure proper power is connected to the motor starter from the building breaker panel. Turn the black toggle switch to the on position to start the fan. To shut the fan down, turn the black toggle switch to the off position. If the motor starter detects a fault, it will automatically shut the fan motor off. Press the blue R button to reset the motor starter. If the fault continues, see the troubleshooting section of this manual.
Sequence of Operation
Operator turns fan toggle switch to on position
Power energizes the coil of MR1 contactor
MR1 contactor pulls in and sends power out to fan motor
Thermal overload mounted at the bottom of MR1 contactor monitors current flowing to motor. If current flowing to motor exceeds overload setting, power is de-energized to motor to prevent motor damage.
Optional Features (when field connected)
MR1 contactor pulls in and sends 120vac power through door limit switches, and light limit switches to compressed air solenoid.
Compressed air solenoid energizes allowing compressed air to feed to the spray equipment. In the event of a system fault, the compressed air solenoid will de-energize which will stop the spraying operation.
