2.4

Operating principle

The microspeed uni motor system comprises the following components: ■ control unit with coolant pump for universal application ■ two motor connection cables (with and without hand control) ■ various motors with different types of coupling ■ one pistol handpiece ■ two shaver handpieces (with and without hand control) ■ two foot controls 2.4.1

Control unit

Control unit 1 has been designed for the mains voltage range 100 V to 240 V / 50 Hz to 60 Hz. The mains voltage is converted into protective low voltage for supplying the motors. Control unit 1 features two motor connection sockets 5 for connecting two (different) motors, and one foot control connection socket 14 (on rear panel of the unit). The following maximum number of devices can be connected to control unit 1 at the same time: ■ two motors and ■ one foot control (GD668 or GD671). Note Only one motor can be activated at any one time. ► Do not connect two shaver handpieces GD682 at the same time. ► Do not connect two XS Highspeed motors GD675 at the same time. Motors with motor-side plug connection GD674, GD676, GD677, GD678, GD679 and GD685 can be used, both with hand control (motor cable GD673) and with foot control GD668 or GD671 (with motor cable GD672).

Note When two motors without hand control are connected to the control unit (motor cable GD672), a motor can only be activated if the motor release switch of the motor that is to be activated is in the “ON” position while the other motor is disabled (motor release switch in “OFF” position). With one shaver handpiece GD682 and one XS Highspeed motor GD675 connected to the control unit, operation can be switched from one motor to the other only by pressing the appropriate control key on the display in the inactive motor control panel, provided the motor is not active.

2.4.6

Instruction menu

Note The instruction menu can only be called up on the control unit. This control key is pressed to call up the instruction menu. The instruction menu can be used to change the information about errors indicated on the display and device settings such as the user language and volume of the acoustic alarms/signals. It can also be used to control motor type-specific adjustments and settings: ■ Deceleration and acceleration ramps for each motor type ■ Oscillating or tapping mode (for pistol handpiece GD684) ■ Oscillation frequency and acceleration ramp in oscillating mode (in shaver blade operating mode of shaver handpieces GD681 and GD682) ■ Reset: for restoring the factory settings 2.4.7

Motor recognition

The control unit 1 recognizes the motor type connected to one of the motor connection sockets 5 on the control unit 1 and displays this type in the corresponding motor control panel of the display 2. The most recent settings for this motor type at the same motor connection socket are shown on display 2. The settings can be changed, within the motor-specific ranges, either on the display or via hand or foot control (in the device settings menu), see Technical data. The motor control panel of the most recently activated motor is always illuminated, whereas the motor control panel of the motor not most recently activated, or disabled, has a gray background. If only one motor is connected to control unit 1, the corresponding control panel is illuminated, provided this motor is not disabled. Saw program (only in conjunction with low-speed motors GD678 and GD679) In this program, the maximum speed setting is limited to 16 000 1/min. The settings most recently used with the saw program (selected maximum speed, dose level for coolant pump 4) are recalled automatically.

2.4.8

Auto-save device settings

The most recent settings for this motor type at this motor connection socket (maximum speed setting, delivery rate, etc.), are called up automatically after a motor change, whenever the same motor type is registered as being connected to the same motor connection socket of control unit 1. Note After each system power-up, both the coolant pump and all motor typespecific special functions such as the saw program (for GD678 and GD679) or the oscillating or tapping mode (for GD684), are generally deactivated (even if previously released or activated). All parameters are reset when the control key “Factory setting” in the instruction menu is pressed. 2.4.9

Overload protection

The motor temperature is monitored in order to protect the micro motors against thermal destruction. Initially, the user is warned of thermal overload (overheating) well in advance of protective shutdown. ■ Level 1: An acoustic warning signal is emitted and the display 2 flashes “Temp. Motor”. Continued overloading causes control unit 1 to switch to level 2. ■ Level 2: The motor is deactivated and the message “Error 7 - Motor overheated” appears on display 2. After a cooling phase the motor can be reactivated. We recommend keeping a replacement motor on standby. 2.4.10

Close coolant pump

Note The coolant pump only works when a motor is running! After each system power-up, coolant pump 4 is generally deactivated (even if previously released for operation). The microspeed uni control unit 1 is equipped with coolant pump 4. This coolant pump serves exclusively for cooling or irrigating the tools. For the coolant, we recommend infusion solutions up to 1000 ml, e.g. NaCl 0.9 % from B. Braun. The delivery rate at the highest dose level is approx. 100 ml per minute. The coolant pump can be activated either in the respective motor control panel or via the appropriate hand or foot control device. The delivery rate can be set via the pump control panel or the device settings menu, see Submenu Device-specific settings.

Exception: For pistol handpiece GD684 and shaver handpiece with hand control GD681, the pump can be activated and the delivery rate changed, only via the appropriate control panels on the control unit. Any one of 21 dosage settings can be selected. At dosage settings 1 to 5, coolant pump 4 runs in intermittent mode. The pump can be activated and deactivated, and the delivery rate changed, even while the motor is active. At dosage setting 4 or higher, a special drive control function prevents leakage of further coolant after the motor has been active for more than two seconds. Additionally, the “Flush” button function allows instant filling of the pump tube with the coolant. When pressing the “Flush” button, the coolant pump is activated at the highest dosage setting. After flushing for more than two seconds, a special drive control function prevents further leakage of coolant. This function can be activated at any time, with or without connection or activation of a motor. 2.4.11

WARNING

Risk of injury due to uncontrolled movement of skin abrading handpiece GB280 in conjunction with a motor cable and hand control GD673! ► Use skin abrading handpiece GB280 only with motor cable GD672 and foot control.

Note A motor cable is required to connect motors (with motor-side plug connection) GD674, GD676, GD677, GD678, GD679 and GD685 to the control unit. The microspeed uni motor system comprises a motor cable for foot control (GD672) and a motor cable with hand control (GD673). Both motor cables can be used in conjunction with all motors with a motor-side plug connection. Either of the two motor cables can be connected to any of the two motor connection sockets 5. Note The selection of motor cable depends on the application and handpiece to be used. Note When using saws GB128R, GB129, GB130R and the motor cable with hand control GD673, we recommend guiding the saw with both hands for optimal handling. If single-handed saw guidance is required, use motor cable GD672 with a foot control for optimal handling.

Aesculap® microspeed uni motor system

When control unit 1 recognizes that a pistol handpiece GD684 is connected, the pistol handpiece operates in standard mode (default setting). The device parameter settings (maximum speed setting, delivery rate, pump status) can be changed only via the touch control panel of control unit 1. Oscillating or tapping mode can be preselected via the instruction menu. The symbol for “Oscillating or tapping mode” is displayed in the respective motor control panel. Oscillating or tapping mode is activated via the upper trigger. An acoustic warning signal is emitted and“ Oscillating or tapping mode active” flashes in the respective motor control panel. In this operating mode, the maximum speed setting cannot be changed via the touch control panel on control unit 1. The oscillating or tapping mode can be deactivated again via the upper trigger. On system power-up and each time the pistol handpiece is connected, the “oscillating or tapping” mode is deactivated by default and has to be reactivated via the pistol handpiece. The setting selected in the instruction menu is saved and remains in the memory even after system restart. Standard operation: Right and left rotation mode (when in left-rotation mode, control unit 1 emits an acoustic signal). Motor direction switch/trigger for left rotation 34, see Fig. 8: ■ Pressing lower trigger 35 while holding down upper trigger 34 makes the pistol handpiece operate in left-rotation mode. ■ The motor direction is changed by pressing trigger 34 with trigger 35 already actuated. Motor speed control trigger 35: ■ Actuator for reference speed setting (motor speed proportional to the actuation stroke). ■ If only trigger 35 is pressed, the pistol operates in right rotation mode. Oscillating or tapping mode: Activating or deactivating the operating mode: see Fig. 8: ■ This operating mode is activated (and deactivated) by pressing and holding upper trigger 34 for three seconds. Working in “Oscillating or tapping mode”: ■ The pistol handpiece is operated in tapping mode by pressing lower trigger 35 within the first half of the total actuation stroke. The motor speed is proportional to the actuation stroke. Tapping mode means: Clockwise angled rotation (forwards) followed by counterclockwise rotation (backwards) at a smaller angle. ■ The pistol handpiece is operated in oscillating mode by pressing lower trigger 35 within the second half of the total actuation stroke. The motor speed is proportional to the actuation stroke. Oscillating mode means: Clockwise angled rotation followed by counterclockwise rotation at the same angle.
