Slack wire

What does 83 mean?

The slack wire function has been activated, indicating that the hoisting wire or chain has lost tension. This is a safety mechanism implemented by the R&M Materials Handling Frequency Converter to prevent damage to the wire, drum, or load.

Click steps to track your progress.

1. 1

   Inspect the entire hoisting mechanism (hoisting wire/chain, drum, pulleys, load path) for actual slack, obstructions, or the load resting on a surface causing loss of tension.

2. 2

   Verify the physical condition, alignment, and proper mechanical actuation of the slack wire limit switch or sensor.

3. 3

   Check all wiring connections from the slack wire sensor to the Kone CMXC-022 Frequency Converter for looseness, damage, or disconnections.

4. 4

   Verify the digital input status for the slack wire function in the frequency converter's diagnostic menu and confirm relevant parameters are correctly configured.
