Exiting menus and screens
Press the ESC key to exit the menu or screen you are in at any time. This returns you to the next higher menu.
All menus and screens are closed automatically if no key is pressed for 10 minutes. The display then jumps to
the Main Menu or to the Alarm menu if any fault report is currently active.
Special functions
A number of special functions can be accessed by key combinations:
‐ triggering a test alarm with the priority X1..X9 by simultaneously pressing the buttons MODE + 1..9
Note: test alarms are only triggered locally at the operator terminal and are used for testing the alarm wiring
at its relay outputs.
‐ triggering of a restart by simultaneously pressing the buttons MODE + ESC + 8
‐ triggering of a first start by simultaneously pressing the buttons MODE + ESC + 9
Frequent restarting while the Store Computer is powering up (about 2 min.) can result in errors in
archive management.

The release of the lock is only to be carried out by service personnel!
With activated setpoint interlock (restricted setpoint changes) a password is necessary.
