Many Palfinger crane error codes can be prevented through regular maintenance:
While many error codes can be resolved by operators, certain situations require professional service:
[Error Code Appears] │ ▼ [Check Power & Voltage] ───(Low Voltage?)───► [Charge Battery / Check Alternator] │ ▼ (Voltage OK) [Inspect Physical Sensors & Cables] ───(Damage?)───► [Repair/Replace Wiring] │ ▼ (Wiring OK) [Execute System Reset] ───(Code Cleared?)───► [Resume Operation Safely] │ ▼ (Code Persists) [Consult Manual for Advanced Calibration] 1. Verify Power and Voltage
Manuals often include specific fault trees for hydraulic malfunctions (like a stuck solenoid ) that don't always trigger an electronic code but cause mechanical failures .
, in contrast, indicate an actual system fault that requires attention. Unlike status codes, error codes do not disappear automatically—even after the underlying problem has been repaired. The operator or service technician must manually reset the system by pressing the OLP (Overload Protection) button or restarting the system. Error codes are typically denoted with two stars (**) in technical documentation. Palfinger-crane-manual-error-codes
Inspect the pressure transducer on the main lifting cylinder. Spool position error Main Control Valve
Illegal voltage at DV-output; check for external power supply or short circuits. A: Missing voltage at J1/2; check the main fuse. Reading & Resetting Codes Scanreco P2 and Hetronic Error Codes | PDF | Radio - Scribd
When encountering a Palfinger crane error code, follow these steps to troubleshoot and resolve the issue:
The method for viewing active codes varies by the specific Paltronic system installed on your crane: Paltronic 40 PK8501 SLD Many Palfinger crane error codes can be prevented
A Lifesaver for Palfinger Crane Operators - Comprehensive Manual with Error Codes!
Analogous to code 20, but isolated to the knuckle boom cylinder circuit.
Check the malfunction display on the aerial platform unit for real-time status updates. Common Paltronic 50 Error Codes & Meanings Paltronic 50
Most Palfinger cranes display error codes on the Paltronic control panel or remote control console. The system stores the last five errors in chronological order, with the most recent error listed first. This error log is invaluable for diagnosing intermittent issues or problems that may not be immediately apparent. Unlike status codes, error codes do not disappear
Indicates a Bus Off scenario, CAN transmitting, or receiving failure. This usually implies a communication break between the radio remote receiver and the main unit. 61.99: RRC (Radio Remote Control) initialization error. Overload & Pressure Sensor Errors 01: HPLS (High Power Lifting System) load limit exceeded. 02: Nominal load limit exceeded. 07.00: Overload on rope winch.
Turn off the PTO (Power Take-Off), shut down the truck ignition, and wait 60 seconds. Restart the system to see if the error code clears. Temporary software glitches or brief sensor spikes will resolve during a hard power cycle. Advanced Diagnostic Tools
The Paltronic 50 and 150 systems manage the crane’s core electronics. Codes in the 80s typically indicate normal working conditions, while those marked with double stars (**) or appearing as specific numeric sequences indicate errors. Likely Cause/Remedy EPROM Checksum Error The crane cannot be operated; internal memory error. 03.
