Ground Module Configuration

When it becomes necessary to replace a ground or power module on a JLG machine, it must be properly configured after installation. Use your JLG® Analyzer, or the new JLG® Mobile Analyzer, for configuration by accessing the “Machine Setup” menu and choosing the correct model and options appropriate to your machine.

If possible, before you replace the module, record all of the settings. This will allow you to set everything back to the correct settings. You may also consult your machine’s service manual to get the default factory settings.

Take a look at this video for a brief overview of the JLG Analyzer’s Machine Setup functions.
