- Page 11 ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.

Page 12: Commissioning
Let us review three variations of a heavy start: 1. The feed line performance is barely sufficient or insufficient to maintain the induced current. Typical symptoms: Upon starting the circuit breakers at the system input are tripped; the lights, certain relays and contactors go off, and the supply generator shuts down. -
Page 13: Technical Maintenance
TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! PRIOR TO COMMENCING ANY TECHNICAL MAINTENANCE PUT UP A PROHIBITORY SIGN ON THE FAN STARTING PANEL: “DO NOT SWITCH ON! MEN AT WORK!” AVOID LIQUID SPILLS ON THE MOTOR! DO NOT USE AGGRESSIVE SOLVENTS AND SHARP OBJECTS FOR CLEANING! Disconnect the unit from power mains and wait for all rotating parts to be at a complete standstill before carrying out any technical maintenance and repair operations. - Page 14 POSSIBLE REASONS AND TROUBLESHOOTING Problem Possible reasons Troubleshooting The fan does not get started. No power supply. Check the automatic circuit breaker. Check the electric connections. Jammed motor. Carefully check the fan impeller for possible seizure and eliminate it, if necessary. If the impeller is in order, replace the electric motor.
