5.4.1Selecting a sectioning mode / start and stop sectioning

Three different sectioning modes can be select- ed for motorized sectioning:

Sectioning mode 1 - Intermittent stroke: The specimen head travels up and down as long as the RUN/STOP and RUN/ENABLE keys are pressed simulta- neously or as long as the footswitch is depressed.

Sectioning mode 2 - Continuous stroke: The specimen head travels up and down until it is stopped by pressing RUN/STOP or RUN/ENABLE or by depressing the footswitch.

Sectioning mode 3 - Single stroke:

The specimen head carries out one sec- tioning stroke and then stops in the low- er limit position.

Activating a sectioning mode

Press one of the three sectioning mode keys de- scribed above. While a sectioning mode is ac- tive, the LED in the corresponding key will be il- luminated.

Start / stop motorized sectioning

Sectioning mode 1 - Intermittent stroke:

Simultaneously press and hold RUN/STOP and RUN/ENABLE or depress and hold footswitch.

To stop the sectioning stroke, release the keys or the footswitch:

The specimen head stops immediately.

Sectioning mode 2 - Continuous stroke:

Simultaneously press and release RUN/STOP and RUN/ENABLE or depress and release footswitch.

To stop sectioning:

Press and release RUN/STOP or RUN/EN- ABLE or depress and release the footswitch:

The specimen head stops upon reaching the lower limit position.

Sectioning mode 3 - Single stroke:

Simultaneously press and release RUN/STOP and RUN/ENABLE or depress and release footswitch.

The instrument carries out one complete section / retraction stroke and the specimen head stops upon reaching the lower limit po- sition.

While sectioning is in motion, LED ‘RUN’ is illu- minated.

While the sectioning motor is deactivated, LED ‘STOP’ is illuminated.

Both LEDs are located in functional area C.
