12.5.6 Test Menu
Access to the Test menu is password protected.
The menu shows the state of the CB, in the dialog module (COM module) the state of the springs and the position of the CB, and in this submenu
you can make the CB open or close.
Using the "Trip Test" function lets you view the disabling/enabling of the Trip. If it is enabled, the circuit-breaker is opened. The function is only
available with a busbar current of nil (use Vaux, PR030/B or PR010/T).
On the page, only with Vaux, you can also see the state of the circuitbreaker "STATUS", and thus make sure that the input is correctly wired.
