Test primary object

The circuit breaker and other switching devices can be tested from this
submenu. The object control buttons are used to perform the desired tests. A
warning message is displayed before leaving the test primary object mode.
In test mode, the interlockings are disabled. It is strongly
recommended to de-energize the switchgear before activating
the test mode.
Verify the primary object's correct position before leaving the
test mode and before energizing the switchgear. Make sure all
the primary objects are back in the correct positions.
