Operators of JLG ES series scissor lifts may occasionally encounter a "Power Module Failure Personality Range Error" that halts equipment operation and disrupts work schedules. While this error message appears technical, its solution often lies in addressing simple battery connection issues or recent battery replacements.

This specific fault code frequently appears in ES series models and typically relates to power supply configurations. When battery connections become unstable or when new batteries are installed, the system may fail to properly recognize the equipment model, triggering the error message. Fortunately, resolution doesn't require extensive technical intervention.

1. Access Level 1: Using the equipment analyzer, log into the control system with Level 1 access privileges.
2. Modify Equipment Model: Navigate to system settings and change the equipment model designation to any alternative model (the specific alternative model selected is unimportant).
3. Emergency Shutdown: Activate the emergency stop (E-Stop) switch to power down the equipment.
4. Power Cycle: Restart the equipment's power supply.
5. Restore Correct Model: Re-access the system with Level 1 privileges and reset the equipment model to its proper designation.
6. Final Shutdown: Engage the emergency stop switch once more to power down the system.

Following this sequence typically clears the error message by forcing the system to reinitialize model recognition parameters. The process effectively resolves configuration errors stemming from battery-related issues.

Safety remains paramount throughout this procedure. Operators should verify the equipment is in a secure state before initiating any troubleshooting steps and strictly adhere to operational manuals. If the error persists after these steps, consultation with certified JLG technicians is recommended for comprehensive diagnostics.
