Brief description
Thanks to the Sonatic Duo
supplementary set, the
Sonatic gas cylinder level
measuring device can display
the contents of a second gas
cylinder on the existing con-
trol unit simply by switching
over the „C“ switch.
If a second gas cylinder of
the same type and size is
being used, the gas cylinder
size previously set can be ad-
opted.
If another gas cylinder size is
used, this must be set at the
operating unit (see Sonatic
Operating Instructions).
If your Sonatic is in perma-
nent operation, and you
switch from one gas cylinder
to the other, the new value
will appear on the display in
about 15 minutes. By press-
ing the right-hand button „B“
on the operating unit, howev-
er, it is possible to start a new
measurement immediately.
The prognosis facility will cor-
rect the new residual running
time automatically, within a
very short space of time.
Installation
instructions
Installation and repairs
may only be carried out by
qualified personnel. Read
the installation instructions
carefully before starting work,
and follow them closely.
Important installation
instructions
1. The screened measuring
cable (length 6 m) must not
be shortened, lengthened, or
kinked.
2. If an aperture (5) needs to
be drilled from the gas cylin-
der container directly into the
interior of the vehicle, in or-
der for the cable to be laid
satisfactorily, this aperture
must be located at least
50 cm above the base, and
then sealed with silicone or a
similar material.
3. In order to avoid faulty mea-
surements, the measurement
cables (4) (including the cable
of the Sonatic) must be laid at
a distance of at least 20 cm
from the electric leads (for
halogen lights in particular).
4. Standing on the mount will
cause the gas cylinder to be
raised up by about 20 mm. If
necessary, the securing
arrangement for the cylinder
will need to be adjusted by
the appropriate means in or-
der for the cylinder to be se-
cured in the specified man-
ner!
Installation of the gas
cylinder mount
Fig. A: Release the securing
element of the second gas
cylinder and lay the mounting
(1) beneath it in such a way
that the measurement cable
(2) can be guided in a pro-
tected position, next to the
existing measurement cable
of the first mounting, outside
the cylinder box.
Secure the cylinder once
again, so as to ensure that it
is set vertical on the cylinder
mount.
Mark the four securing points
or the contour line, and take
the mount out again.
