: CAN-bus errors. These indicate communication failures between the main control unit and external modules like the remote control or spool position sensors.
Before diving into specific codes, it is essential to understand why the system generates these errors. Modern Palfinger cranes are governed by sophisticated electronic control systems (often referred to as the PLC or Loading Computer). These systems constantly monitor sensor data, hydraulic pressure, and operator inputs.
These codes usually point to "broken connections" or signals out of the normal range (typically less than 1.25 mA or greater than 19.7 mA).
