Loadrite LR915 Clock and Date Code Access and System Overview

[MikePhua]

The Loadrite LR915 loader scale requires a specific access code to adjust its internal clock and date settings. This code is typically reserved for authorized technicians or system administrators and is not publicly documented. Without it, users cannot modify time-related parameters directly from the interface.
Loadrite LR915 background and system architecture
The Loadrite LR915 is a precision onboard weighing system designed for wheel loaders. Manufactured by Loadrite, a New Zealand-based company founded in the 1970s and later acquired by Trimble, the LR915 was part of a broader push to digitize load tracking and improve quarry and construction site efficiency.
Key features include:

• Real-time weight measurement during bucket lift
  
• Data logging for loadout and productivity tracking
  
• RS232 or CAN-based communication with external systems
  
• LCD interface with keypad for basic configuration
  
• Internal clock for timestamping load events
  

The LR915 was widely adopted across Europe, North America, and parts of Africa, especially in aggregate and bulk material handling operations. Its reliability and simplicity made it a favorite among operators, though its configuration menu was intentionally limited to prevent unauthorized changes.
Clock and date adjustment protocol
To change the clock and date:

• The user must enter a technician-level access code
  
• This code unlocks the configuration menu beyond standard calibration
  
• Once inside, the operator can navigate to the time/date submenu
  
• Changes are confirmed and stored in non-volatile memory
  

The code is typically provided during installation or training and may vary by region or distributor. In some cases, the code is hardcoded and cannot be changed without factory intervention.
Security rationale and operational impact
Restricting access to time settings serves several purposes:

• Prevents tampering with load timestamps
  
• Ensures data integrity for billing and compliance
  
• Avoids accidental misconfiguration by untrained users
  

Incorrect time settings can lead to:

• Misaligned shift reports
  
• Duplicate load entries
  
• Confusion during audits or reconciliation
  

One operator in Serbia noted that his LR915 displayed the wrong date after a power cycle. Without the code, he was unable to correct it, leading to mismatched load logs across a week-long project.
Workarounds and support options
If the code is unavailable:

• Contact the original distributor or installer for technician access
  
• Provide serial number and site details to verify ownership
  
• Some models allow remote reset via diagnostic software
  
• In rare cases, a firmware update may reset the clock
  

Avoid attempting hardware resets or unauthorized firmware flashing, as this may void warranty or corrupt calibration data.
Preventive measures and best practices

• Record the access code during installation and store securely
  
• Sync the LR915 clock with site systems monthly
  
• Use external data loggers or telematics for redundancy
  
• Train operators to recognize time drift and report discrepancies
  

Conclusion
The Loadrite LR915 requires a technician-level code to adjust clock and date settings. This restriction protects data integrity but can hinder operations if the code is lost. With proper documentation and distributor support, time settings can be restored and synchronized to maintain accurate load tracking across projects.
