FAQs

What is the primary function of the SCHNEIDER ATS48D47Y?

This soft starter smoothly controls motor acceleration, reducing electrical and mechanical stress. It protects the motor from common faults like overcurrent.

The SCHNEIDER ATS48D47Y limits the inrush current when a motor starts. This gentle start process prevents sudden jolts to machinery.

It also offers programmable acceleration and deceleration ramps for optimized motor control across various applications.

How do I wire the SCHNEIDER ATS48D47Y for a 400V motor?

Connect your main power supply to the L1, L2, and L3 input terminals. Ensure correct phase rotation.

Wire the motor leads (T1, T2, T3) to the corresponding output terminals on the soft starter. Follow the recommended conductor sizes.

Connect the 230V AC control voltage to the designated control terminals for operation and configuration.

What are the key benefits of using the ATS48D47Y over a direct-on-line starter?

It significantly reduces the high inrush current associated with DOL starting, preserving electrical infrastructure. This leads to lower peak demand charges.

The ATS48D47Y minimizes mechanical shock on driven equipment like pumps and conveyors, extending their operational life. This reduces maintenance costs.

By controlling acceleration, it prevents water hammer in fluid systems and reduces wear on belts and gearboxes.

Can the SCHNEIDER ATS48D47Y protect against phase loss?

Yes, the ATS48D47Y includes integrated phase loss protection. It detects a missing phase during operation.

If a phase is lost, the soft starter will safely shut down the motor to prevent damage. This is a critical safety feature.

The starter will then indicate a fault code, allowing for quick identification of the issue.

What is the rated operational current of the SCHNEIDER ATS48D47Y?

The product is rated for a maximum operational current of 47 Amperes. This is the continuous current the starter can handle.

This current rating determines the size of motor it can control at specific voltage levels. Always match the motor's full load current.

Ensure the supply wiring and overload protection are sized appropriately for this 47A rating.

How do I set the acceleration time on the ATS48D47Y?

Access the starter's programming menu via the control interface. Navigate to the acceleration parameter settings.

Input the desired acceleration time in seconds. This defines how long the motor takes to reach full speed.

Test the setting with a controlled start to ensure smooth ramp-up for the connected load.

What kind of motors can be controlled by the ATS48D47Y?

This soft starter is designed for three-phase AC asynchronous motors. It provides controlled starting for these common motor types.

It is suitable for standard squirrel cage induction motors. Consult the manual for specific motor compatibility details.

The starter optimizes torque for smooth starts, protecting the motor and driven equipment.

What are common fault codes for the ATS48D47Y?

Common faults include overcurrent (FLt 01), overvoltage (FLt 03), and undervoltage (FLt 04). These indicate electrical supply issues.

Other potential faults relate to motor overheating (FLt 06) or internal starter issues (FLt 08). These require careful diagnosis.

Refer to the official Schneider Electric manual for a complete list and troubleshooting steps for each code.

Is the SCHNEIDER ATS48D47Y suitable for outdoor use?

The ATS48D47Y has an IP20 protection degree, making it suitable for indoor industrial environments. It is not designed for direct outdoor exposure.

To use it outdoors, it must be installed within a suitable enclosure that provides adequate protection against dust, moisture, and UV radiation.

Always ensure the enclosure maintains proper ventilation to prevent overheating of the soft starter.
