Timers menu

Safeties menu

The "safeties" menu provides useful information for trouble shooting
purposes. The following screens contain basic information.

Along with the basic information, more detailed information screens
can be consulted while the safety menu is active. Press the

  key.

Screens similar to the following will appear.

History menu

The "history" menu contains all the information concerning the latest
shutdowns. The structure of those menus is identical to the structure
of the safeties menu. Whenever a failure is solved and the operator
performs a reset, the concerning data from the safeties menu is
copied into the history menu. Warnings are also recorded.

Additionally the number of safeties that already occurred, can be
consulted on the first line of the history screens.
