Torque Limiter; Switching Device Off - Nouvag OFA-Drill Bedienungsanleitung

7.5

Torque limiter

This device comes with a built in torque limiter that works just like a torque wrench.
If the attached instrument detects increasing drag the torque is raised and the speed is reducing, if
necessary up to a stand still. The torque at the instrument persists. If the load on the instrument decreases
the speed picks up again up to its maximal output setting.
The procedure can be followed at, watching the bar graph in the lower right of the display. The segments of
the bar graph are filling up the more drag is building up on the instrument. When maximum torque is
reached, means all segments of the bar graph are visible, the speed is declining. As soon as the load on the
instrument is reduced, the torque decreases and the motor speeds up again.

Switching device off

At switch-off, the settings made by the user are automatically saved. This includes the following
parameters:
• Handpiece
• Max. speed
• Max. 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.
When the OFA-Drill device is switched on, the display shows always the last used settings.
By pressing both „HP + PR"-keys at the same time the memory slots can be reset to the factory default
settings.
