3 1. Operation 1.1 Typical Operation of the Motor Starter Ensure proper power is connected to the disconnect from the building breaker panel. Turn the red disconnect handle to the On position. Turn the Fan toggle switch to the on position to start the fan. To shut the fan down, turn the Fan toggle switch to the off position. If the control panel detects a fault, it will automatically shut the fan motor off. See the troubleshooting section of this manual to determine common causes of motor faults. Turn the Lights toggle switch to the on position to turn on the lights. To shut the lights off, turn the Lights toggle switch to the off position. 2. Sequence of Operation 2.1 In Depth Explanation of How the Control Panel Works Operator turns fan toggle switch to on position, power is sent to terminal #6 which feeds to optional fire suppression equipment. If fire suppression equipment is not faulted, power returns on terminal #3 which feeds to the coil of MR1 contactor. Power energizes the coil of MR1 contactor. MR1 contactor pulls in and sends power out to fan motor. Motor protector mounted at the top 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 to terminal #4 which feeds to the door limit switches. If doors are closed, power returns on terminal #40 which feeds power to the light lens reed switches. If all lenses are proven closed, then power returns on terminal #41 which feeds power to an optional filter proving assembly (jumper 41 and 42 if not used). When terminal #42 becomes energized, the compressed air solenoid will turn on. 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. Operator turns lights toggle switch to on position. Power energizes the coil of LC1 contactor. LC1 contactor pulls in and sends power to terminal #5 which feeds out to light fixture(s). 2

6 4. Troubleshooting 4.1 Solutions to Common Issues Fan motor does not start Symptom Fan Motor Starts but Makes Humming Noise Fan Motor Runs For A Few Moments Then Turns Off Motor Starter Makes Buzzing Noise When Turned On Light Contactor Makes Buzzing Noise When Turned On Possible Solution Confirm proper incoming voltage on top of MP1 protector between terminals L1 and L2. Confirm proper voltage at the bottom of MP1 motor protector beteen terminals T1 and T2. With fan switch turned on, confirm proper voltage on bottom of contractor between terminals T1 and T2. With fan switch turned on, confirm proper voltage on contracter coil between terminals A1 and A2. Motor is wired incorrectly. Motor can be wired for use on various voltages. Use schematic on name plate of motor to properly connect motor to voltage being applied. Motor is overloaded. Use amp meter to determine if motor is pulling too many amps based on motor name plate. Remove belts from motor and attempt to run with no belts. Motor protector is adjusted incorrectly. Determine the FLA (full load amps) of the motor by checking the motor name plate (ensure the voltage being applied to the motor is known). Adjust the thermal overload to match the motor nameplate. Motor is overloaded. Use an amp meter to determine how many amps the motor is pulling then compare that number to the thermal overload and motor name plate. Incorrect voltage applied between terminal A1 and A2 on contactor coil. Use a volt meter to confirm the voltage on those terminals matches what is printed on the coil. Confirm proper incoming voltage on top of LC1 contactor between terminals L1 and Neutral. With light switch turned on, check for voltage on terminal T1 of LC1 contactor. If voltage is present, check wiring to light fixtures. With fan switch turned on, confirm proper voltage on contactor coil between terminals A1 and A2. Incorrect voltage applied between terminal A1 and A2 on contactor coil. Use a volt meter to confirm the voltage on those terminals matches what is printed on the coil. 5

7 5. Preventitive Maintenance Schedule 5.1 PM Schedule Once Per Month Check motor amperage with amp meter. Press "test" button on thermal overload to ensure it will turn off the motor in the event of a fault. Once Per Year Disconnect power coming into the motor starter. Ensure all wiring connections are tight (over time connections can become loose due to heating/cooling cycles on the wires when a motor is turned on/off). Disconnect power coming into the motor starter. Remove junction box cover from motor and check the wire nut connections to ensure they are tight. Inspect junction box for unusual discoloration which could indicate overheating. 6.
