display codes directly on the main control unit or the radio remote controller (RRC) screen. Common Paltronic 50 Error Codes The following table outlines frequent codes found in the Paltronic 50 safety system: Common Cause/Solution ** Service interval required Reached limit for crane or rope winch maintenance 81. * High stand limitation active Safety limit engaged on high stand 1 or 2 90. * Fly-jib load limit reached Movements restricted due to fly-jib overload 93. * Crane load limit reached All lifting and moment-increasing movements disabled 94. * Lever not in neutral Lever moved during or after an overload situation 96. * Power Fail Low voltage detected in the system 05.011 ** Emergency loop error Fault in the emergency stop circuit or feedback Specialized Remote & Sensor Codes
On systems like the , codes are often displayed as two numbers. The first number (followed by a dot) is the main code, and the second is the additional information (e.g., 63.07 ). Common Paltronic 50 Error Codes & Solutions Common Reason Recommended Action 03. Overload Situation Crane has reached its lifting capacity limit. Reduce the load moment by retracting or lowering the boom. 11. Pressure Transducer (Piston) Signal less than 1.25 mA from U230 sensor.
Contact a Palfinger Service Center for professional inspection. Lever Not in Neutral A lever was moved during an overload reset.
: The decimal point isn't just punctuation—it’s critical for pinpointing the exact sensor or circuit that's failing. A Glossary of Warning Signs
: On EPS 2/3, codes often show as Axx (alarm) or Fxx (fault). palfingercranemanualerrorcodes
Elias flips to his manual, where the numbers tell a story of what's happening under the hood:
Disclaimer: This article is for informational purposes only. Always refer to the official Palfinger operator and service manual for your specific crane serial number and model. Improper diagnosis of hydraulic or electronic systems can result in serious injury or death.
For operators and service technicians, having access to the correct is as essential as the hydraulic fluid that powers the boom. This article explains why these codes matter, how to interpret them, and why you should never ignore a flashing warning.
Bypass mode disables all electronic safeties. It should only be used to stow the crane for transport to a repair shop. Finding Specific Manuals display codes directly on the main control unit

| Symptom | Most likely error code | Check first | |---------|------------------------|--------------| | No function, remote connected | E 03, E 31 | Receiver fuse, ECU power | | Crane moves slowly | E 20, E 21 | Oil level, cooler fan | | Boom won’t lift heavy loads | E 10 | Pressure sensor, overload setting | | Stabilizer light stays red | AL 32 | Stabilizer microswitch / proximity sensor | | Display blank but remote works | – | Backlight fuse or display ribbon cable |
| Code | Description | Remedy | | :--- | :--- | :--- | | 03.* | Overload on a crane load limit | The second code indicates which specific limit is overloaded. Reduce the load moment or use the OLP button to safely lower the boom. If the crane is for workman basket mode (EN 280), check the wiring and signal. | | 07.* | Overload on rope winch | Reduce the load moment. |
You may need to press the MLX button or restart the crane to clear the error. 3. Common Palfinger Error Codes List Below are common error codes identified in: Error Code Designation/Meaning 01 (01.xx) * Fly-jib load limit reached Movements restricted due
: Encoder/Sensor address errors often caused by initialization failures or "Angle change too quick" detections.
Walk around the unit and verify that no physical buttons are accidentally bumped or compressed.
Broken connection on main boom piston side (signal < 1.25 mA). Pressure Sensor General pressure sensor fault; disables all motion. Angle Sensor Fault in the angle measuring channel. Analogue Channel
PALDIAG allows service departments to plug directly into the Paltronic system to read real-time sensor voltages, track historical fault logs, adjust speed parameters, and recalibrate sensors after a component replacement. If your manual error code points to an internal module failure or requires recalibration, contact an authorized Palfinger service center. Summary Reference Table Error Category Likely Source Primary Checkpoint Cylinder Transducers Check sensor plugs for moisture Position / Geometry Inclinometers & Proximity Switches Inspect sensor alignment on booms Communication CAN-Bus Network Check battery voltage & main harnesses Stability Outrigger Limit Switches Clean dirt/debris from stabilizer legs
Short circuit in the pressure transducer cable or main unit. Inspect cables for damage; reset system via OLP or restart. Self-check error in the radio controller. Check for internal hardware, sync, or bus/COM errors. 71.xx - 72.xx Encoder issues (e.g., angle change too quick or no answer). Reset the blinking code. E01 - E05
The method used to retrieve error codes depends completely on the design generation of your Palfinger console:
