The method used to retrieve error codes depends completely on the design generation of your Palfinger console:

Reading the output: Note the position of the decimal point, as a change in digits shifts the exact system component sub-class. Paltronic 50 & 150 Systems (Classic & Modern PK Series)

Check the wiring harness connecting the main valve block sensors to the PALTRONIC unit. 2. Geometry and Extension Sensor Codes

Inspect the proximity switches and angle sensors for physical alignment or damage.

Palfinger cranes communicate faults through numerical strings displayed on the console or the remote control transmitter. The specific process to retrieve a hidden code depends heavily on your system architecture. Paltronic 40 Systems PK8501 SLD

| Code | Cause | Elimination | | :--- | :--- | :--- | | | The boom has been luffed up (raised) too far, falling below the minimum radius or exceeding the maximum angle allowed in the load chart. | Luff the boom down into a radius or angle listed in the load chart. | | E02 | The boom has been luffed down (lowered) too far, exceeding the maximum radius or falling below the minimum angle allowed. | Luff the boom up into a radius or angle listed in the load chart. | | E03 | The boom position is outside the permissible working area (e.g., slewed over the front of the truck). | Move or slew the boom back to the permitted working area. | | E04 | The operating mode switch in the console is incorrectly set, or the selected mode is not permissible for the current crane configuration. | Correctly set the operating mode to the code assigned to the crane's configuration. | | E05 | The boom is telescoped too far or not far enough for the permitted working range. | Extend or retract the boom to the correct length, as specified in the load capacity chart. | | E18 / E83 | These are less common codes related to sensor or specific geometry monitoring errors and may require service intervention. | Consult the service manual for advanced troubleshooting. |

Look for a flashing sequence or a direct digital readout (e.g., "E01" or a specific two-to-four-digit number).

: A "Broken Connection." Specifically, the pressure transducer on the main boom piston side has lost its signal.

by cycling the main power if the OLP button does not clear the fault.
