5.8.4 Operation of the SCR system
The keys can be used to call up information, change
parameters and initiate processes. Usable keys are
displayed, or the functions of the F keys appear,
depending on the screen or selected function, above
the F1 to F4 keys.
Press "OK" to exit the top level or select a submenu.
A function or setting option is selected via the
up/down keys. The left/right keys are used to change
values. The various service screens are selected in
the submenu using a combination of the OK key and
the left/right keys.
In automatic mode, the initial display page is always
shown after a certain time without any key being
pressed.
The F1 key can be used to switch the system on or
off. Switching on is generally automatic when the
CHP unit is started up (as long as the enable values
for engine load and exhaust gas temperature have
been reached). The system is switched off manually
by pressing the F1 key for at least 10 s.
