Use
The ENESKA 3-2 grinding, milling, and polishing system is used in tool and mould making and in
engineering workshops for surface fi nishing.
Two micromotors are available with di erent speed and output ratings. The motors are driven
electrically via a control unit.
Together with various handpieces it is thus possible to select exactly the right combination for
any requirement and to suit any working use.
For recommended tools please see the joke catalogue section on “Driving motors and handpie-
ces”.

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 infi nitely
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 fi xpeed switch for more than 1 second . A „beep“
sound and the fi xpeed LED will light. The motor is now set to run at the fi xpeed
setting. To change fi xpeed 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 fi xpeed is preset for both
motor 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.

After loosing the hand screws on both sides, the support arm can be
pivoted into di erent resting positions.

with corresponding micromotors. The speed set accordingly for the
connected micromotor appears on the speed display (7.1/4).
The micromotors connected to both connection sockets A and B cannot be operated simultane-
ously.

The six LED’s (3 green, 2 orange and 1 red) indicate the load bearing
capacity during the working process. Ideally, only the three green
LED’s should illuminate during prolonged working processes.

set operating mode.

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 fi tting properly one
inside the other. In this case turn the shaft of the handpiece until the coupling notches into place.
Tighten the handpiece fi rmly with a hook spanner.
Figure 7.3 Schematic drawing
Do not apply any force! This could cause irreparable damage to the motor bearings.

Do not exceed 13 mm overhang for mounted grindstones. In case of overhang must exceed 13
mm reduce the motor speed in accordance with the following table:
Overhang (mm): 20, max. operating speed rpm: N x 0.5
Overhang (mm): 25, max. operating speed rpm: N x 0.3
Overhang (mm): 50, max. operating speed rpm: N x 0.1

Additional functions
Tempomat key
An additional speed (less than the preset speed) can be set within the preset speed range using
the foot switch:
1. Press the button on the motor cable (7.1/18) for more than one second
2. The speed is saved and can be read on the display (7.1/4).
Memory function key (memory key)
The memory key makes it possible to save a speed and a direction of rotation (clockwise or
anticlockwise) for both channels (A or B). Set the desired speed using the rotary knob, in addition
to the direction of rotation.
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 speed now remains constant however at the saved rpm.
One speed and one direction of rotation can be saved for each motor output, which is also retai-
ned 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.
Maintenance/Care
Control unit
The unit does not require any maintenance. Clean it with a dry, soft cloth.
Handpieces
Clean the contact surfaces whenever you change the tool.
When you change the handpieces, check that the threads are clean.
Ensure absolute cleanliness when changing the collet and only use the spanners provided. Clean
up the collet one time/week.
Mircromotors
The brushless motor does not require any maintenance. All ball-bearings are encapsulated and
permanently lubricated.

Troubleshooting
The control unit is fi tted with an over-load cut-out switch.
If the switch in the control unit has responded, the cause is likely to be:
The handpiece or the micromotor is continually being loaded at its maximum limit. In this case
wait for about 3 to 5 seconds. It will then be possible to resume operation
Error Code Description Cause
Speed display does not
light.
• The power plug is disconnected.
• The fuse is blown.
• Power switch is faulty.
Speed display and set
rotation speed is displayed
repeatedly.
• Put the power switch, depressing the foot pedal.
E 1 Overcurrent detection
error.
• long-time use at a high load
• shorted cord (power line)
• shorted motor winding
E 3 Motor sensor error. • faulty sensor
• disconnected motor cord
E 4 Unit overheat error. Temperature rise in the unit due to long-time use at
a high load.
• Unit placed under a high temperature.
EF Foot pedal error. • Faulty foot pedal or shorted foot pedal cord.
