What causes error E01 on Hirschmann Measuring Instruments and how to fix it?
Error E01 indicates that the minimum radius has been fallen below or the maximum angle specified in the load chart has been exceeded because the boom was luffed up too far. To fix this, luff down the boom to a radius or angle specified in the load chart.
What does error E02 mean on Hirschmann HC3901 and how do I resolve it?
Error E02 means the maximum radius has been exceeded or the minimum angle specified in the load chart has been fallen below because the boom was luffed down too far. You should luff up the boom to a radius or angle specified in the load chart to resolve this.
How to fix error E12 on Hirschmann HC3901?
Error E12 is caused by a defective or loose cable between the central unit and the force transducer, water inside the plug of the transducer, a defective force transducer, or a defective electronic component in the measuring channel. To solve this, check the cable and plugs, replace them if necessary, replace the force transducer, or replace the sensor unit.
What should I do if Hirschmann HC3901 Measuring Instruments display error E61?
Error E61 indicates a defective or unconnected CAN Bus cable between the central unit and the sensor unit, a defective CAN Bus port in the central unit, or a short circuit in a CAN Bus cable. Check the connection between the central unit and the sensor units. Replace the central unit or the CAN Bus cable.
What does error E06 on Hirschmann HC3901 mean, and how can I fix it?
Error E06 indicates that the maximum radius as specified in the load chart has been exceeded, or the minimum angle has been fallen below due to luffing down the luffing jib too far. To resolve this, luff the jib to a radius or angle specified in the load chart.
What causes error E15 on Hirschmann HC3901?
Error E15 can be caused by a defective or loose cable between the central unit and the angle sensor, water inside the plug of the angle sensor, a defective angle potentiometer, or a defective electronic component in the measuring channel. Check the cable and plugs, replace them if necessary. You may also need to replace the angle sensor or the sensor unit.
What to do if Hirschmann Measuring Instruments show error E37?
If error E37 appears, it indicates that the system program file is defective or the Flash-EPROM is defective. To resolve this, upload a valid system software or replace the central unit.
Why am I getting error E38 on my Hirschmann HC3901?
Error E38 occurs because the system program in the LMI does not match the programming in the crane data file. To correct this, upload a valid system program file or the valid crane data file.
What to do if Hirschmann HC3901 Measuring Instruments show error E07?
If error E07 appears, it means that the relay indicates an overload while CU input 20 is on, or the relay indicates no overload while CU input 20 is off. To resolve this, check the cable to the overload relay and CU input 20, and also check the relay itself.
What does error E43 mean on Hirschmann HC3901 Measuring Instruments?
Error E43 indicates that the write/read memory (RAM) or central unit is defective. To resolve this, replace the central unit.

The Hirschmann HC3901 is a Load Moment Indicator (LMI) designed for various crane types, including telescopic boom cranes, lattice boom cranes, and all-terrain cranes. Its primary function is to provide the crane operator with essential real-time information to ensure operation within the crane's design parameters. This system operates on a reference/real comparison principle, continuously monitoring and comparing actual crane conditions with pre-programmed safe operating data.
The HC3901 LMI system provides critical data such as boom length, boom angle, working height, working radius, rated load, and the actual weight being lifted. It achieves this by utilizing various sensors, including an angle sensor and force transducers. When non-permitted conditions are approached, the LMI system issues warnings through audible alarms and warning lights. Furthermore, it can interface with the crane's control system to stop dangerous movements, such as lifting and luffing down, to prevent overloads and ensure safety.
The system is an operational aid, designed to warn operators of approaching overload and over-hoist conditions that could lead to equipment damage or personnel injury. It is crucial to understand that the LMI is not a substitute for good operator judgment, experience, or adherence to accepted safe machine operating procedures. The LMI primarily protects against overload in the boom's vertical range and does not account for non-vertical lifting, ground inclination, or derailed wheels.
The HC3901 LMI system consists of three main components:
HC3901 Controller: This is the central processing unit and display.
WG103 Angle Sensor: This sensor accurately measures the boom angle.
KMD Force Sensor: Designed for static and dynamic tensile force measurements, known for high overload capacity, fatigue strength, and corrosion resistance.
The HC3901 features a user-friendly operation and display interface.
Regular inspection and maintenance are crucial for the LMI system's proper functioning and longevity.
