Inspect cables for shorts; reset system using the Overload Protection (OLP) button . Service Interval Scheduled maintenance is due.
| Code | Likely Cause | Immediate Action | |------|--------------|-------------------| | | Emergency stop pressed | Release E-stop, reset system | | E 02 | Low battery voltage (radio remote) | Replace/recharge remote battery | | E 03 | Communication lost between remote and crane | Re-pair remote; check receiver fuse | | E 05 | Joystick not in neutral at startup | Center joysticks, power cycle | | E 10 | Overload – pressure sensor out of range | Reduce load; check pressure transducer | | E 11 | Angle sensor fault (main boom) | Check wiring/connector at boom pivot | | E 12 | Extension sensor fault | Check cable extension sensor or magnetic strip | | E 13 | Rotation sensor fault | Check slip ring or rotary encoder | | E 20 | Oil temperature too high (>80°C) | Let crane cool; check cooler/return filter | | E 21 | Low oil level | Top up hydraulic oil; check for leaks | | E 30 | CAN bus error | Check wiring harness, terminating resistors | | E 31 | ECU internal error | Cycle power; if persists → replace ECU | | AL 32 | Stabilizer not deployed or interlock active | Fully extend stabilizers or bypass (not recommended) |
Accompanying LEDs indicate whether the error is tied to the emergency stop, geometry sensors, or overload protection systems. 2. Scanreco Remote Controls
Velocity calculation unrealistic; replace defective structural encoder. Outriggers Maximum Outrigger Support Force Exceeded. palfingercranemanualerrorcodes
Repair the sensor, wiring, or clear the overload. Press MLX: Press the MLX button on the console.
These are informational and appear during normal crane operation (e.g., reaching a load limit). They usually disappear automatically once the condition is corrected (e.g., reducing the load moment).
- Often related to operating outside safe limits. 46 (46.xx) Inspect cables for shorts; reset system using the
| Crane model example | Manual type | Error code section | |--------------------|-------------|--------------------| | PK 6502, PK 8502 | EPS 2 / EPS 3 | Chapter 8 – Fault codes | | PK 10000, PK 16000 | EPS 4 | Chapter 10 – Diagnostics | | PTC (Compact) | EPS 1 | Appendix B – LED blink codes |
Palfinger crane manual error codes are specific alphanumeric codes that appear on the crane's control panel or display screen when a fault or issue is detected. These codes serve as a diagnostic tool, providing valuable information about the nature of the problem, allowing technicians to quickly identify and address the issue. By understanding these error codes, operators and technicians can reduce downtime, prevent further damage, and ensure the crane operates safely and efficiently.
For Palfinger tail lifts with MBB control boards, the one-digit codes on the small display indicate the following: Repair the sensor, wiring, or clear the overload
Your Palfinger service manual differentiates explicitly between two forms of notification: Status Codes (Operational Info)
Troubleshooting Palfinger Crane Error Codes: A Technical Guide
- Communication fault within the CAN bus system. 47 (47.xx) Crane BUS Watchdog Error - CAN bus communication failure. 48 (48.xx) Crane BUS Sign of Life Error - Module not responding. 50 (50.xx) Crane BUS Connection Fault - CAN bus wiring issue. 4. Troubleshooting Common Codes A. Overload Situations (32.xx/Status 81) If the crane displays an overload status ( ), the Paltronic has restricted operation.
Luff down, retract, or slew the boom back into the permitted load chart area. How to Retrieve Codes
Change the remote battery, select a different radio channel, or connect the backup cable directly to the crane. Step-by-Step Diagnostic Protocol for Operators
