How to resolve error E51 on Hirschmann Measuring Instruments?
Error E51 indicates no valid data in the crane data file or a defective Flash-EPROM. Upload a valid crane data file or replace the central unit.
What does error E60 mean on Hirschmann HC3901 Measuring Instruments?
Error E60 indicates no valid data in the load chart file, the base number not programmed, or the load chart file wrongly programmed. Upload a valid load chart file. Program the correct base number (1 for base 1, 2 for base 2). Check base programming in the load chart file.
What does error E39 mean on my Hirschmann HC3901 Measuring Instruments?
Error E39 means that the system program in the LMI and the programming in the load chart file do not match. Upload a valid system program file or the valid load chart file to resolve this.
What does error E84 mean on Hirschmann HC3901 Measuring Instruments?
Error E84 means that the selected rigging condition is not contained in the crane data file. Select another rigging condition or check the programming in the crane data file.
What does error E83 mean on Hirschmann Measuring Instruments?
Error E83 means that the force actuating on the main boom pendants has exceeded the programmed value. Reduce the force acting on the main boom pendants.
What does error EB1 mean on Hirschmann HC3901 Measuring Instruments?
Error EB1 can be caused by no rope on the winch, no sensor for winch measuring available, rope length not calibrated, wrong rope/winch parameters in data-programming, counter input not defined in configuration, or a defective counter input. Calibrate the rope length, mount a sensor or disable the function in data-programming, calibrate rope length and layer, check parameters in data-programming, change I/O configuration, or change Iflex.
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 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.
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 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.
