LOTO Trainer for HV Vehicles Datasheet

  • Lucas-Nuelle CX3226-1A7 LOTO Trainer for HV vehicles with simulated high-voltage automotive components

The Lucas-Nuelle CX3226-1A7 is a practical training system for teaching safe high-voltage isolation and lockout/tagout procedures for battery-electric, plug-in hybrid, and hybrid-electric vehicles.

Students learn to identify electrical hazards, choose an appropriate isolation method, verify that the vehicle is safe to service, investigate simulated faults, and recommission the vehicle after work is complete.

  • Vocational schools and community colleges
  • OEM, fleet, and workforce training centers
  • High school automotive programs
  • Recognize electric-vehicle high-voltage hazards
  • Become proficient with methods of vehicle isolation
  • Investigate faults and system status
  • Verify safe working conditions
  • Reinitialize and recommission vehicles safely

Scan Tool Simulation

An integrated interface supports fault insertion and simulates a scan tool with diagnostic trouble codes and live data.

Multiple High-Voltage Isolation Methods

Training covers Live-Dead-Live measurements, manual service disconnects, 12-volt disconnection, cutting loops, high-voltage fuses, smart-key storage, scan-tool shutdown, and warnings for incorrect operation.

Simulated High-Voltage Circuit

The system represents an HV battery, contactor operation, high-voltage interlock loop, drive motor, DC/DC converter, and equipotential bonding circuit.

Guided Learning

Guided instruction modes and assessment activities reinforce correct procedures and decision-making.

Use of Real Workshop Tools

Students practice safety procedures using the same types of equipment used when servicing real vehicles.
