Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the Schneider Electric TeSys D Contactor Coil, model LXD1V7. This coil is designed for use with TeSys D contactors and auxiliary contactors, specifically compatible with LC1D09 to D38 and LC1DT20 to DT40 series, operating at 400VAC 50/60Hz.
Please read this manual thoroughly before installation and operation to ensure safe and efficient use of the product. Keep this manual for future reference.
Product Overview
The LXD1V7 coil is a critical component for TeSys D contactors, enabling their electromagnetic operation. It is engineered for reliability and compatibility within industrial control systems.
Key Features
- Designed for TeSys D contactors (CAD and LC1D series from 9A to 38A).
- Operating voltage: 400VAC at 50/60Hz.
- Ensures quick and easy implementation with compact design.
- Compatible with various connection types including spring terminals, EverLink terminal block, screw brackets, closed terminals, and Feston terminals.
- Suitable for AC, DC, and DC low power control circuits.

Setup and Installation
Installation of the contactor coil should only be performed by qualified personnel in accordance with all local and national electrical codes and regulations. Ensure power is disconnected before beginning any installation work.
Pre-Installation Checks
- Verify that the coil's voltage (400VAC) and frequency (50/60Hz) match the control circuit supply.
- Confirm the coil is compatible with the specific TeSys D contactor model (e.g., LC1D09-D38).
- Inspect the coil for any physical damage or deformities. Do not install if damaged.
Installation Steps
- Disconnect Power: Ensure all power to the contactor and control circuit is completely disconnected and locked out.
- Remove Old Coil (if applicable): Carefully remove the existing coil from the contactor, noting its orientation and connection points.
- Insert New Coil: Align the LXD1V7 coil with the designated slot in the TeSys D contactor. Gently push it into place until it seats securely. Ensure the terminals are correctly oriented for connection.
- Connect Wiring: Connect the control circuit wires to the coil terminals. Ensure connections are tight and secure to prevent loose contacts and overheating. Refer to the contactor's wiring diagram for correct polarity if applicable.
- Verify Installation: Double-check all connections and ensure the coil is firmly seated.
- Restore Power: Once installation is complete and verified, restore power to the control circuit and test the contactor's operation.
Operating Principles
The LXD1V7 coil functions as an electromagnet. When the specified voltage (400VAC) is applied across its terminals, current flows through the coil windings, generating a magnetic field. This magnetic field attracts the armature of the contactor, causing the main power contacts to close or open, thereby controlling the flow of power to a load (e.g., a motor).
Upon removal of the control voltage, the magnetic field collapses, and a spring mechanism returns the armature to its original position, opening or closing the contacts as designed. The coil's impedance and design are optimized for efficient and reliable operation within the specified voltage and frequency ranges.
Maintenance
Regular maintenance helps ensure the longevity and reliable operation of the LXD1V7 coil and the contactor it is part of. Always disconnect power before performing any maintenance.
- Visual Inspection: Periodically inspect the coil for signs of overheating (discoloration, melting), physical damage, or loose connections.
- Cleanliness: Keep the coil and surrounding contactor area free from dust, dirt, and debris, which can impede heat dissipation and lead to premature failure. Use a dry, lint-free cloth or compressed air.
- Connection Integrity: Check terminal connections for tightness. Loose connections can cause resistance, leading to heat buildup and potential failure.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent undue stress on the coil.
Troubleshooting
This section provides guidance for common issues. For complex problems, consult a qualified electrician or Schneider Electric support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Contactor does not engage when control voltage is applied. | No control voltage, incorrect voltage, open circuit in coil, coil failure, mechanical obstruction. | Check control circuit voltage. Verify wiring connections. Test coil resistance (if possible, with power off). Inspect for foreign objects preventing armature movement. Replace coil if faulty. |
| Coil overheats or emits burning smell. | Overvoltage, incorrect frequency, shorted turns in coil, loose connections, excessive ambient temperature. | Verify control voltage and frequency. Check for proper ventilation. Inspect connections for tightness. Replace coil if internal damage is suspected. |
| Contactor hums excessively. | Incorrect voltage, mechanical issue with armature, foreign material on pole faces. | Verify control voltage. Inspect armature for free movement. Clean pole faces. |
