Read the operating and
mounting instructions be-
fore commissioning.
Only specialised personnel
may perform work on the
automatic burner control system.
Never perform any work
when the control system is
live. This also applies if low-volt-
age components such as servo-
motors, display or communica-
tion components are replaced or
installed.
In case of fuse failure,
check the safety function
of the automatic burner control
system. Otherwise contact weld
caused by short-circuit may oc-
cur.
Only specialised personnel
may set operating param-
eters.
Only use the communica-
tion connection together
with components expressly ap-
proved for this purpose.
Perform the connection re-
lated to the correct phase
and the protective conductor con-
nection according to the terminal
diagram and check it before com-
missioning.
Warranty for the control
system expires on im-
proper handling of the electronic
system or due to incorrect stor-
age.
The data contained in these
instructions specify the au-
tomatic burner control system.
They do not imply any character-
istics.
If you do not follow these
instructions, danger to life
to the equipment may occur.
