PROGRAMMING / OPERATING
THE FUNCTION KEYS
DOCUMENTATION FOR ROUTING DIAGRAM
GENERAL:
The programming is menu-controlled. The main menus are numbered in
level 0 (x.0), and the submenus are numbered in level 1 (x.1 to x.5). Each
submenu has an accompanying entry menu. The menus are structured in
such a way that the menus most frequently used are closer to the default
menu 0.0. Please note that programming is only possible when submenu 5.4
PAS has the value 040.
Menus and submenus are select-
ed by the 3 function keys 2, 3,
and 1 as outlined in the routing
diagram.
Activating 2 will display the cur-
rent value. In entry menus, the
digit that can be changed will flash.
Active digit position is shifted by
the 3 key, and the value is changed
by the 1 key. When the decimal
point flashes, its position can be
changed by the 3 key.
In parameter selection menus you
switch between the parameters by
the 1 key.
Store by first activating 1 and
then 3 simultaneously.
To return to the previous menu without changing the parameters - activate
2.
If a non-valid value is entered, the display will show Err for 2 s and then
return to the entry menu with the initial parameters.
