The Schneider Electric TeSys LE enclosed Direct On-Line (DOL) starter is designed for straightforward and efficient motor control. The TeSys LE DOL starter includes all necessary components for motor starting and protection in a compact, enclosed unit.

Key Features

1. Integrated Design: Combines a contactor and thermal overload relay in a single enclosed unit.
2. Ease of Installation: Pre-wired and ready to use, reducing installation time.
3. Protection: Provides motor overload protection and can include short-circuit protection with optional fuses.
4. Manual Control: Simple start and stop buttons for direct manual control of the motor.
5. Durability: Robust enclosure suitable for industrial environments.

Components

1. Contactor: Switches the motor on and off by connecting and disconnecting it from the power supply.
2. Thermal Overload Relay: Protects the motor from overheating by disconnecting it if an overload condition occurs.
3. Start and Stop Buttons: Allow manual control of motor starting and stopping.
4. Enclosure: Provides protection for internal components against dust, moisture, and physical damage.

Operation

• Starting the Motor: Press the start button to energize the contactor, closing the contacts and supplying power to the motor.
• Running the Motor: The motor runs at full speed, directly connected to the power supply.
• Stopping the Motor: Press the stop button to de-energize the contactor, opening the contacts and disconnecting the motor from the supply.
• Overload Protection: If the motor draws too much current, the thermal overload relay trips, opening the contactor and stopping the motor to prevent damage.

Installation and Setup

1. Mounting: Securely mount the starter in a suitable location.
2. Power Supply Connection: Connect the line supply (L1, L2, L3) to the input terminals on the contactor.
3. Motor Connection: Connect the motor leads to the output terminals (T1, T2, T3).
4. Overload Relay Setting: Adjust the overload relay to match the motor's full-load current rating.
5. Testing: Test the start and stop functions to ensure the system operates correctly.

Troubleshooting Tips

1. Motor Does Not Start: Check the power supply and ensure that the contactor is functioning. Verify the start button is operational.
2. Motor Overheats: Ensure the overload relay setting matches the motor’s full-load current and is not tripping frequently.
3. Frequent Tripping: Check for short circuits or grounding issues in the motor wiring. Verify that the motor is not overloaded or malfunctioning.
