: This is often the primary fix recommended by specialists. Jungheinrich released updates specifically to expand the neutral zone "window" to prevent these sensitivity-related errors.
: Mechanical play or "backlash" in the tiller handle components can prevent the sensor from returning to the exact zero point. Troubleshooting and Solutions jungheinrich eje 120 error code 4372
: The "window" for the neutral position in the tiller head is too small, causing the sensor to send an "analogue implausible" signal even if the tiller is at rest. Outdated Firmware : This is often the primary fix recommended by specialists
| Step | Action | |------|--------| | 1 | – Turn off, wait 30 seconds, restart. Check if error returns immediately or only under load. | | 2 | Visual inspection – Check the encoder cable and connector at the drive motor for damage, corrosion, or loose pins. | | 3 | Resistance check – Measure encoder winding resistance (if resolver type) between reference and sine/cosine pins per manufacturer specs (usually 20–100 ohms). | | 4 | Continuity test – Check each encoder wire from motor connector back to controller connector. | | 5 | Shielding check – Verify the encoder cable shield is intact and grounded only at the controller side. | | 6 | Swap test (if available) – Replace drive motor with a known good unit or test motor encoder separately. | Troubleshooting and Solutions : The "window" for the
