Describing of the operating elements of the control unit

Figure 7.1/1: Handpiece holder takes up the handpieces.

Figure 7.1/2: Forward/reverse selector switch Select the direction of rotation with the forward/reverse selector switch. Each time this switch is pressed, the direction changes. When the FWD./REV. is not lit, it shows right hand rotation (FDW.).

Figure 7.1/4: The rotating regulator allows the rpm of the relevant micromotor to be infinitely varied up to the maximum level 40,000 rpm (is equivalent to 40).

Figure 7.1/5: Memory Speed Function, Fixpeed First with the motor stopped, preset the desired speed on the speed control knob(7.1/4). Next press the fixpeed switch for more than 1 second . A „beep“ sound and the fixpeed LED will light. The motor is now set to run at the fixpeed setting. To change fixpeed memory, repeat the above procedure.

Fixpeed memory cannot be set over 30,000 rpm!

Next press the memory function key for more than 1 second. A signal sounds and the LED display (7.1/6) illuminates. The rpm now remains constant at the saved speed. One speed and one direc-tion of rotation can be saved for each motor output, which is also retained after switching on the control unit again:

• select the appropriate motor (7.1/14 or 7.1/10)• adjust the speed (7.1/4)• observe direction of rotation (7.1/2)• press the memory key for more than 1 second.

The saved speed can be deleted by further pressing the memory key for more than 1 second. A signal sounds. The LED display (7.1/6) is no longer illuminated.

When the ENESKA 3-2 system is shipped from the factory, the fixpeed is preset for bothmotor A and B to 20,000 rpm.

If the foot pedal is used, the speed range can be varied with a saved rpm up to the set speed.

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.

Connecting the handpiece to the micromotor

First screw the handpiece onto the micromotor by hand!

If you notice any resistance before the thread is screwed on as far as it ought to go, it means that the drive shaft of the motor and the coupling on the handpiece are not fitting properly one inside the other. In this case turn the shaft of the handpiece until the coupling notches into place. Tighten the handpiece firmly with a hook spanner.

Figure 7.3 Schematic drawing

Do not apply any force! This could cause irreparable damage to the motor bearings.
