Torque limit function, AL mode (Automatic Limiter)

The AL function limits the torque applied to the instrument, for example to prevent crack initiation and bone
fracture.
The speed at the instrument remains constant until the preset torque is reached. If the applied force gets over this
limit the speed will be reduced, if necessary down to a stop, but the torque remains constant. If the applied force is
reduced the speed picks up again.
On the display this procedure is shown as a bar graph. The bars in the graph fill up to their full range as the torque
increases to its preset value. When the bar graph shows full capacity the speed will be reduced. As soon as the force
on the instrument is reduced the torque decreases and the speed starts to pick up again as shown on the display.
The AL mode is active at all speeds, except at the speeds where the AS mode takes effect.
7.6

Torque limit function, AS mode (Automatic Stopper)

The AS function limits the torque applied to the instrument. As soon as the preconfigured torque is reached, the
electronic motor stops immediately. The electronic motor no longer generates any force. In order to restart the
electronic motor, the treadplate must be released and pressed again.
On the display, the bar graph completes up to its full range, until the maximum torque is reached, then drops to
zero.
The function "AS" is just active for certain contra angles
and only in a certain speed range.
From the minimal speed up to the speeds shown at the
right the AS-mode is activated automatically.
(refer to "7.8 Configuration Menu, Parameter level 2, AS-Zone")
The upper limit of the AS range can be adjusted in the configuration menu.
In the following speed ranges the AS-/AL-mode can also
be switched manually by pressing both torque keys
"Torque ▲ + ▼" at the same time.

Storing various programs

With the MD 30, up to 10 different settings per motor can be set as fixed program (program 1 to program 10). Which
program is currently active can be seen on the display.
At switch-off, the settings made by user are automatically saved. This includes the following parameters:
• Handpiece/Transmission ratio
• Maximal speed
• Maximal torque
To change a program go to the specific parameter and change it. When the device is switched off all parameters are
saved in that program.
The number of storable programs can be limited in the configuration menu from 3 to 10 programs.
When the MD 30 is switched on, the display shows the prior used program and motor.
