While exact code definitions can vary slightly depending on your specific crane model, Paltronic generation, and configuration, the following codes represent the most frequent issues encountered in the field: 1. Overload Protection System (OSK / Standard Overload)
And below that, in handwriting not her own: "Counting continues. Always."
The crane has reached 100% of its rated lifting capacity.
The electronic actuator on the hydraulic valve bank is stuck or not matching the remote command.
Check wire continuity to sensor U230 ; replace connector plug. Sensor Loops Main Boom Pressure Sensor Broken (Rod Side). palfingercranemanualerrorcodes
Palfinger cranes utilize Paltronic systems (40, 50, or 150) to display specific error codes, which can be retrieved via the main console, base display, or remote control. Common codes include 31.00 for support overload, 33.00 for angle limits, and "ES" for emergency stop faults, with the Palcode app often used for diagnosis. For a detailed breakdown of these codes, visit Scribd's Palfinger Guide . Tools & Applications - PALFINGER
Accompanying LEDs indicate whether the error is tied to the emergency stop, geometry sensors, or overload protection systems. 2. Scanreco Remote Controls
: Without the official manual or the PALDIAG software, a numeric code like "42" or "F3" is meaningless to an operator.
: The codes are usually very specific (e.g., identifying exactly which solenoid valve is drawing too much current). While exact code definitions can vary slightly depending

Reduce tension force on the active line cable; retract extensions. Emergency Circuits Emergency Stop Valve Return Signal Error.
Call a certified dealer immediately if you see:
| Error Code | Description | Immediate Action | | :--- | :--- | :--- | | | Left joystick out of neutral range | Center the stick. If code remains, recalibrate via Paltronic menu. | | 202 | Right joystick signal missing | Check wiring harness under the cab floor. | | 213 | Potentiometer worn out (Jittery signal) | Replace the remote lever potentiometer kit (Part #6303452). | | 235 | Proportional valve coil short circuit | Measure resistance at the coil (should be 8-12 Ohms). | The electronic actuator on the hydraulic valve bank
Range limits (radius exceeded, angle too high, or slewing restricted).
Velocity calculation unrealistic; replace defective structural encoder. Outriggers Maximum Outrigger Support Force Exceeded.
Voltage drops are the leading cause of phantom error codes in mobile hydraulics. Ensure the truck engine is running at the proper idle speed and check that the battery terminals are clean. Step 4: Utilize the Emergency Cut-Off Override (If Safe)
