This submenu allows testing the HMI and the primary part of the switchgear.

Test HMI

When the test HMI is selected, all its features will be tested by switching them on
and off.
HMI buttons are not available during the test. The displayed
information on the HMI does not reflect the switchgear's actual status.
REF 542plus is protecting the switchgear during the HMI test. The
HMI test takes a few seconds.
