6.5.1 Calling up the settings by the user
Using the
"+"
and
"-"
buttons, the user can
also call up other relevant data (step 1 to
step 4). The step numbers are not displayed.
See the following table for calling up the user
data. After a timeout of 5 minutes during
which time no button has been pressed, the
display reverts to the standard operation
mode. You can scroll through the menu with
the
"+"
button. The
"-"
button is only used to
return to step 1. Set values cannot be
changed in this menu.
6.5.2 Calling up the settings by the in-
staller
There is a more extensive program for the
installer for calling up data. All data available
to the installer can be called up by pressing
and holding the
"F"
and
"OK"
buttons at the
same time for approx 3 seconds. However,
the values cannot be modified or changed in
this menu.
After this menu is called, it always opens with
step number 7 (see following table). The
installer and user data is called with the
"+"
button and the
"-"
is used to return to step 0.
This menu is automatically closed if no button
is pressed for 5 minutes and the display
reverts to the standard operation mode.
In the case of a fault, the fault number ap-
pears in the display.
