Chassis Up or Down Switch ON

What does 12 mean?

The chassis up or down switch is detected in an ON position, potentially causing unintended chassis movement. This condition disables chassis control.

• Chassis Up or Down switch stuck in an active state.
• Wiring fault causing the switch input to be continuously active.
• Mechanical issue preventing the switch from returning to neutral.

1. 1

   Inspect the mechanical operation and physical condition of the "Chassis Up" and "Chassis Down" switches for any sticking, damage, or foreign material preventing full return to the OFF position.

2. 2

   Measure the electrical continuity or voltage output of each "Chassis Up" and "Chassis Down" switch in both activated and deactivated states to confirm proper electrical switching.

3. 3

   Check the wiring integrity and connections from the "Chassis Up" and "Chassis Down" switches to the Kone Kone Elevator Control input module for any shorts, loose terminals, or insulation damage.

4. 4

   Verify the real-time input status of the "Chassis Up" and "Chassis Down" signals within the Kone Kone Elevator Control's diagnostic interface or PLC monitoring tools, comparing it to the physical switch state.
