4.6 Switching on the instrument
When turning the instrument on with the mains switch, do not press any of the buttons of the
control panel or the foot switch (optional accessory)!
Turn the instrument on with the mains switch at the rear.
This is followed by a beep.
The instrument initializes.
The software version is displayed in the 4-digit display for approx. two
seconds. Then the display reads "
0000
".
After the microtome is switched on, the display fields and LEDs of all acti-
vated functions are lit up on the instrument’s control panel and display
field.
The three-digit LED display indicates the last value set for the section
thickness or trimming thickness, depending on which setting was last
activated. This is indicated simultaneously on the control panel and
microtome.
The LED of the active mode (here the section thickness) is illuminated in
green.
When the red LED in the
E-STOP
field (
2
) on the control panel of the
instrument is illuminated, either
•
the emergency-stop function has been activated
(the EMERGENCY STOP button is pressed or the foot switch depressed)
•
the dummy plug (or the optional foot switch) is not correctly connected
to the jack, or not connected at all.
If the yellow LED in the
M-STOP
field (
4
) of the control panel is lit, the me-
chanical handwheel lock or the handwheel brake (
Item 3 in Fig. 3
) is
activated.
The instrument cannot be started as long as the LED is lit.
