The general wiring diagram shows all the main
connections of the complete MX2 system.
The connections actually required depend on the
integration of the MX2 system in the unit and the
desired functions.
The table below describes the main characteristics
of each connection described in the wiring diagram.
Precautions to be taken during integration
• During integration, only use a medical supply
that conforms to standards EN / IEC 60601-1
and EN / IEC 60601-1-2, respecting the required
withstand voltage, creepage distances and dis-
tances in air. Following integration, the complete
assembly becomes an EM system.
• 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 sup-
ply for the light.
• The input voltage levels can be configured via
the RS-232 serial interface (document available
on request).
• For more information or if you have any ques-
tions about the integration, wiring configuration
REF 2100202-0001/ENG
or programming of the MX2 system, please
contact your Bien-Air Dental representative
(addresses below).
• Only use accessories, transducers and cables
specified by Bien-Air Dental SA.
Protection installed
Temperature
• The motor outer surface and electronic control
temperatures are continuously controlled by the
system.
Power supply
• The electronic control system is protected
against over- and undervoltage, and also
against short circuits on the feed input.
Motor and light
• The motor output (phases) is protected against
short circuits.
• The light output is protected against short
circuits.
• Interruption of one, two or three phases is detec-
ted by the system, and the motor either does not
start or stops.
Exhaust air
REF 249.39.11: this system is only necessary if the
device is pneumatically-controlled, with the air
pedal in the raised position, and if the valve control-
led by the pedal is not fitted with a vent. Contact
your dealer for fitting.
Standards
This electronic control conforms to electrical safety
standards in line with standard IEC 60601-1 and
those governing electromagnetic compatibility in
line with standard IEC 60601-1-2.
Electromagnetic compatibility
Corresponds to the electromagnetic compatibility
in accordance with IEC 60601-1-2. Declaration
by the manufacturer regarding electromagnetic
compatibility: refer to the tables on pages 3-4.
Information
The technical specifications, illustrations and
dimensions contained in these instructions are
given only as a guide. They may not be the subject
of any claim. The manufacturer reserves the right to
make technical improvements to its equipment,
without amending these instructions. For all addi-
tional information, please contact Bien-Air Dental
SA at the address indicated on the back cover.
Options
Converter 24/32-24 REF 1500580-001
The DMX2 Plus/DMX2 Pro is fed by 32 Vdc +/-10%.
If your system only has a 24 Vac feed, we recom-
mend that you use this converter. This accessory
enables you to obtain optimum performance from
the MX2 system, by providing two stabilised voltages:
32 Vdc (60W continuous, 130W peak) for the MX2
motor feed.
Dual Motor Switch REF 1500554-001
We recommend this module when using 2 MX2
motors with a DMX2 Plus/DMX2 Pro board. It
allows switching of the 3 motor phases, the 2 light
connections. The relays are switched simultaneously
and controlled by the MUX Control input (24 Vdc).
To connect this electronic control to the MX2
system, please consult the wiring diagram.

Operating mode selection by DIP-Switches
The 4 DIP-Switches are used to configure the system, and in particular to select the operating mode (see table
below). For more information and technical support, please contact your Bien-Air Dental SA dealer.

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).
