Commissioning the control unit and micromotors
1.
Place the control unit in a suitable dry place. Usable temperature should be between 0°
and +40° C and relative humidity (RH) between 10 and 85 %.
2.
Adapt the position, if required by pivoting the support arm (7.1/8).
3.
Make sure the speed control knob (7.1/4) is set at the lowest speed position.
4.
Connect the mains cable to the control unit and a 230 V socket. Place the unit for quick
access of power code (to disconnect in case of emergency).
5.
If required, connect the foot switch (7.2/1) to the control unit by means of a cable.
6.
Set the mains switch (7.1/7) to the „On“ position; the display of the rpm indicator
illuminates.
7.
Select the direction with the forward/reverse switch (7.1/2). Each time this switch is
pressed, the direction changes. When the FWD/REV LED (7.1/3) is not lit, it shows “right
hand rotation”.
8.
Connect the handpiece (consider the instruction manual of the handpiece). Insert the
motor cord plug into the motor A (7.1/15) or motor B connector (7.1/9) and tighten the
motor cord plug nut.
9.
Choose between manual -, foot pedal operation or auto speed system to use the micro-
motor:
Manual operation
Set the rotation speed with the speed control knob (7.1/4) and check the speed on the
speed display. Select the desired motor by pressing either motor A (7.1/10) or B (7.1/14).
After selecting the motor either press the same button one more time, press the smart
switch (7.1/18) or the foot pedal again.
Foot pedal operation
The foot pedal is active in addition to manual mode as soon as it is connected to the
control unit. Set the speed and operate the foot switch in order to variably reach the
optimum speed.
Auto speed system
In order to fix the speed, press the foot pedal until the desired speed is reached and
subsequently press the pushbutton of the required motor (7.1/14 or 7.1/10). The LED dis-
play for the motor illuminates. The speed is maintained even if the foot controller or foot
pedal is released. In order to quit the mode, either press once again the pushbutton for
motors A or B (7.1/14 or 7.1/10), the button on the handpiece (7.1/18) or the foot pedal.
10.
This function is also active when the memory key is used. Plug a second connecting
cable with a micromotor into connection socket B if necessary. If you wish to toggle
between the micromotors, press the appropriate key (either 7.1/14 or B 7.1/10). The LED
display (7.1/13 or 11) indicates which micromotor is operating.
