99

Platform Load is over 99%

Kone · Elevator Control

What does 99 mean?

The detected load on the platform exceeds 99% of its rated capacity. This is a warning only, indicating the platform is at its absolute load limit.

Common Causes

  • Platform loaded at or near its maximum capacity.
  • Malfunction of the platform overload sensor, providing an inaccurate reading.
  • Minor fluctuations in load pushing it over the 99% threshold.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the actual load on the elevator platform against its rated capacity.

  2. 2

    Inspect all wiring and connections for the load weighing system sensors (e.g., load cells) for damage, corrosion, or looseness.

  3. 3

    Check the elevator control system parameters related to load weighing, capacity settings, and calibration values for correct configuration according to manufacturer documentation.

  4. 4

    Verify the physical mounting and integrity of the load weighing sensors to ensure no obstructions or mechanical stress are affecting their measurement.

  5. 5

    Perform a functional test or recalibration of the load weighing system using known weights if the above steps do not resolve the issue, following manufacturer procedures.
