Why does my GST GST5000 Control Panel show 'AC Fault' when I turn it on?

If the GST Control Panel displays 'AC Fault' upon powering up, first ensure the mains supply is active. If the issue persists, the AC fuse might be blown. In this case, replace the fuse, referring to the label for the correct specification.
