1. For the installation, the service engineer is responsible
for assessing the condition of the wall and the type of
wall attachment needed for the unit.
Suitable wood screws for wooden beams are included
in delivery.
For all other types of wall construction, the appropriate
wall plugs must be obtained from a specialized dealer.
The wall plugs and screws should be identical for each
point of attachment.
As an alternative, an anchorplate can be used as a
counter surface. In this case, M8 threaded rods of the
appropriate length (Thickness of wall + 2 x thickness of
Installation plate + mounting hardware) for the wall are
required.
ATTENTION
Support arm till 700 mm: A minimum extraction force of
3600 N is required for the upper wall plugs and screws or for
the threaded rod and nuts.
Support arm 950 mm: A minimum extraction force of
4200 N is required for the upper wall plugs and screws or for
the threaded rod and nuts.

cal installation.
2. For a recessed installation, cut away the cable duct us-
ing the Drilling Template.
Align the Drilling template and tape it into place.
3. Mark the center points for the four points of attachment
and drill them.
– If using the countersupport plate drill through the
wall with an ∅ 8mm (5/16“) drill tip.
– When mounting with wall plugs, drill holes accord-
ing to the plugs used (max. ∅10 mm / 3/8“) and
then insert the plugs..
– For a wooden wall drill the holes with a ∅ 6mm
(1/4“) wood drill tip at least 80mm deep.
Remove the drilling template.
4. For recessed installations only with remote con-
trol:
Draw the end of the remote control cable with a cable
tie into the remote control device. Draw the other end
through opening B.
5. Draw the power cable through opening A. (For Ceiling
Version: also draw in the cable of the overhead support,
see Mounting Instructions for Ceiling Version.)
6. For surface-wiring installations only:
Attach self-sticking cover to the rear side.
7. Align the wall adapter with the spirit level and secure it
with four screws and washers.
8. For surface-wiring installations only:
Run the power cable from below into the installation
plate and relieve strain with a cap clamp.

Using an ohmmeter, check the connection between the
tube assembly support bracket and the grounding point in
the wall adapter. The value should be below 2 ohms. This
measurement is not a substitute for the protective ground
wire test described in the service manual!
2. Remove the adhesive tape.
Push the sliding ring (in the covering tube) downwards.
Push the silicone stop downwards until the joint is cov-
ered.
The covering tube must be flush with the bellows.

Required Measuring Instruments
1. Digital multimeter Fluke 8000 A, Philips PM 2816 rms
or equivalent.
2. Electromechanical pulse counter KESSLER ELLIS, KT
203±1 pulse, or equivalent.
Radiation Protection
Observe the radiation protection guide lines as outlined in
the Operating Instructions manual.
X-radiation is emitted as long as the exposure button is
depressed.
The X-ray indicator must light up during radiation. An
acoustic signal must also be heard.
Line Voltage
Be sure the jumper on generator board DX1 is plugged
according to nominal line voltage as outlined on page 7
Power Supply Adequacy
To assure that the HELIODENT system performance is in
accordance with Sirona specifications, an adequate power
supply is essential.
The Federal Performance Standard for diagnostic X-ray
units, code of Federal Regulations, title 21 CFR, subchap-
ter J, mandates an adequate power supply.
Duty Cycle
Between exposures maintain a cool-off time (automatic
exposure blocage, see Operating Instructions manual).
Operating Instructions
During measurements and controls it is necessary to ener-
gize or de-energize the unit. For all operating steps please
refer to the Operating Instructions manual.

ATTENTION
CAUTION with PC - Boards!
All PC-boards are fitted with electronic components sensi-
tive to electrostatic discharge (ESD). In an environment of
moving people electrostatic charges are unavoidable due
to friction of clothing, carpeting etc.
To prevent damage of electronic chips do not
touch same.
Always handle circuit boards by the edge of
same.
ATTENTION
Electrical Shock Hazard!
Always turn unit OFF before connecting and dis-
connecting the test leads to the test points.

exposure time on the control panel to 3.2s, using the object
selector switch (see Operating Instructions, chapter ”Pre-
paring the Exposure, Select the radiography technique and
Adapting the base value”).
ATTENTION
Mind radiation protection guide lines!
Make an exposure by holding depressed the exposure but-
ton, X-ray lights up, an audible beep sounds at the wall
adapter. ÖRecord the voltage reading.
No load voltage ……VAC
minus voltage under load ……VAC
Voltage drop ……VAC
The maximum permissible voltage drop must not exceed

check:
540mVDC ±200mVDC
– Value for out of tolerance (Volt range):
Check leads to X3 for proper connection (see Sec-
tion “Electrical Connection” , page 7).
ATTENTION
Observe the following with cable extension (e.g.due to ceil-
ing installation, Centro column or Split Concept ):
– Check the voltage behind the cable extension.
Measure on terminal X10 for ceiling installations
and on terminal K2 for the Centro column and the
Split Concept. The voltage measured (on terminal
X10 or K2) will be lower than the value measured
on DX1, however, still must lie within the tolerance
