What does 85 mean?

A button on the Local Control Panel (LCP) has been disabled, likely through a configuration in parameter group 0-4* LCP functions. This is a safety or operational feature to prevent unintended or unauthorized operation via specific LCP buttons.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Confirm that the button is not physically stuck, damaged, or experiencing a mechanical issue preventing its operation.

  2. 4

    Ensure no active security settings (e.g., password protection, control mode lockout) are indirectly disabling the button.
