Power Supply - Bien-Air Dental DMX2 Plus Mode D'emploi

Main functions and controls
• Pneumatic control.
• Electric control by analogue inputs or digital interface (RS-232)
• Control with up to two MX2 motors (using Dual Motor Switch REF 1500554)
• The system variable parameters are as follows:
- Speed range 100 - 40.000 rpm (maximum torque of over 3.0 Ncm
available across the full speed range)
- Progressive or ON/OFF mode speed adjustment
- Maximum torque adjustable from 10 to 100% in 1%* stages
- Brightness control (16 settings) or light ON/OFF
- Reversal of rotation direction (clockwise/anti-clockwise)
- Selection of 'Endodontics'* modes:
- Auto-reverse mode: direction of rotation reverses automatically as soon as
the torque limit is reached (adjustable from 10% - 100% of maximum torque).
- Auto-forward mode: direction of rotation reversed as in auto-reverse mode,
in addition, the motor switches automatically to clockwise operation after an
adjustable period of anti-clockwise rotation (from 0 - 25 seconds).
Precautions to be taken during inte-
gration
• The integration of this product has
to be made by a qualified techni-
cien.
• Caution : since this device is intend-
ed to be used adjacent to or stacked
with other equipment, the responsi-
bility of verifying normal operation
in the configuration in which it will
be used falls onto the dental unit
manufacturer.
ENG
*only DMX2 Pro
• During integration, only use a med-
ical supply that conforms to stan-
dards EN / IEC 60601-1 and EN / IEC
60601-1-2, respecting the required
withstand voltage, creepage dis-
tances and distances in air.
Following integration, the complete
assembly becomes an EM system.
• Caution : the dc power supply line
overall length must be shorter than
3 m. The use of ferrite beads is
strongly recommended and the use
of a filter Schurter KFA4301.5206
may be necessary on the 230Vac.
• Connect the ground (GND) of all the
electronic controls connected to the
DMX2 Plus/DMX2 Pro. This also
applies to digital interfaces.
• The motor light must be powered
from the DMX2 Plus/DMX2 Pro.
Do not use another power supply for
the light.
• The input voltage levels can be con-
figured via the RS-232 serial inter-
face (document available on
request).
• Caution : the overall RS-232 cable
length must be shorter than 3
meters. The use of a shielded RS-
232 cable is strongly recommend-
ed.
• For more information or if you have
any questions about the integration,
wiring configuration or program-
ming of the MX2 system, please
contact your Bien-Air Dental repre-
sentative.
• Only use accessories, transducers
and cables specified by Bien-Air
Dental SA.
Protection installed
Temperature
• The motor outer surface and elec-
tronic control temperatures are
continuously controlled by the sys-
tem.

Power supply

• The electronic control system is
protected against over- and under-
voltage, and also against polarity
reversal.
Motor and light
• The motor output (phases) is pro-
tected against short circuits.
• The light output is protected against
short circuits.
• Interruption of one, two or three
phases is detected by the system,
and the motor either does not start
or stops.
Exhaust air
REF 249.39.11: this system is only nec-
essary if the device is pneumatically-
controlled, with the air pedal in the
raised position, and if the valve con-
trolled by the pedal is not fitted with a
vent. Contact your dealer for fitting.
