Sonatic Duo
Brief description
With the help of the Sonatic
Duo supplementary unit, the
Sonatic L gas cylinder filling
level measuring device can
display the contents of a se-
cond gas cylinder, simply by
switching over at the Sonatic
Duo (A) operating unit.
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 a gas cylinder of a different
size is being used, the setting
needs to be adjusted on the
Sonatic L operating unit (see
Sonatic L operating instruc-
tions).
If your Sonatic L 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 pres-
sing the right-hand button
briefly on the Sonatic L ope-
rating unit, however, it is pos-
sible to start a new measure-
ment 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 order
for the cable to be laid satis-
factorily, this aperture must
be located at least 50 cm
above the base, and then sea-
led with silicone or a similar
material.
3. In order to avoid faulty
measurements, the measure-
ment cables (4) (including the
cable of the Sonatic L) 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 arran-
gement for the cylinder will
need to be adjusted by the
appropriate means in order
for the cylinder to be secured
in the specified manner!
Installation of the gas
cylinder mount
Figure A: Release the secu-
ring element of the second
gas cylinder and lay the mo-
unting (1) beneath it in such
a way that the measurement
cable (2) can be guided in a
protected 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.
Drill four securing holes (take
care to avoid any cables, gas
pipes, etc. which may be lo-
cated beneath), and secure
