display codes directly on the main control unit or the radio remote controller (RRC) screen. Common Paltronic 50 Error Codes The following table outlines frequent codes found in the Paltronic 50 safety system: Common Cause/Solution ** Service interval required Reached limit for crane or rope winch maintenance 81. * High stand limitation active Safety limit engaged on high stand 1 or 2 90. * Fly-jib load limit reached Movements restricted due to fly-jib overload 93. * Crane load limit reached All lifting and moment-increasing movements disabled 94. * Lever not in neutral Lever moved during or after an overload situation 96. * Power Fail Low voltage detected in the system 05.011 ** Emergency loop error Fault in the emergency stop circuit or feedback Specialized Remote & Sensor Codes
If using a radio remote, codes may appear on the receiver or transmitter display. : System is in Standby mode. : System is running normally. Blinking "1" : Weak radio signal. Repeated Beeps/Blinks (1-8)
Confirm radio module electronic box is strictly mapped to Directory 61. 4-Step Field Troubleshooting Workflow
The following table summarizes frequently encountered error codes and their typical causes: Description Potential Cause/Action System Normal Crane is in normal working condition. EPROM Checksum Internal program fault; crane cannot be operated. Load limit reached (General, HPLS, or Nominal). Winch Overload Load moment exceeded on rope winch; movements disabled. E-Stop Feedback Fault in the emergency stop loop. Pressure Transducer palfingercranemanualerrorcodes
The manual explained that the crane's brain was receiving a signal it didn’t trust—a potential overload or a sensor failure. Without a clear reading on how much pressure was in the cylinder, the system had safely "locked out" to prevent a catastrophic collapse.
For aerial work platforms or basket-configured models, you can also trigger code playbacks by on the load-moment indicator panel or basket control. Master Palfinger Error Code Reference Table
The pressure sensor on the main lifting cylinder has exceeded 100% of its rated capacity. display codes directly on the main control unit
Static. Then: "Say again?"
: For tricky codes not in the physical manual, Palfinger provides PALCODE , a mobile app that works offline—perfect for remote sites where reception is a luxury.
She pulled the battered spiral-bound manual from the glove slot. The pages were coffee-ringed and dog-eared, the section on error codes worn almost translucent. E01: Overload. E04: Low hydraulic pressure. E07: Canbus comms failure. Nothing matched the seven-digit sequences on screen. * Fly-jib load limit reached Movements restricted due
: Elias checks the grounding wires . Corrosion or loose connections in the swivel often cause solenoids to "chatter" or trigger false error codes.
For Palfinger tail lifts with MBB control boards, the one-digit codes on the small display indicate the following:
