Navigation in the menus
11.3.1 Navigation in menus without an alarm
A "MENU" key is provided for navigating through the various menu steps. By pressing this key briefly (<2s) at any
time, you can jump to the next menu step. By pressing the key for longer (>2s), you can return to the home position
from anywhere in the menu structure, providing a controller alarm is not active. In this case, the Alarm menu is
opened.
In addition, you always return to the home position if you do not press any keys for a period of 30s. There is no
automatic return after 30s from "AC" [
A
uto
C
al] or "AL" [
AL
arm].
11.3.2 Navigation in menus with an alarm
If an alarm is indicated, the terminal display shows the Alarm menu. Some faults can be acknowledged by pressing
the "RESET" key (
section 11.20 "System monitoring / alarm output" on page 51). In this case, the display
switches back to the home position.
If the fault can be rectified by executing the AUTOCAL function, you can select the "AC" [
A
uto
C
al] menu step
directly by briefly pressing the "MENU" key (<2s). You can then activate the "AUTOCAL" function by pressing the
"ENTER" key (
section 11.8 "Automatic zero calibration (AUTOCAL)" on page 40).
