5.4.5 Coarse feed keys
The four coarse feed keys in functional area B
function as follows:
Coarse feed ‘fast backward’
- Travelling speed 1,000 µm/s
• Press key to activate.
Specimen head travels backward
(= away from knife):
a. until it reaches the rear limit position,
b. until it is stopped by pressing one of the
coarse feed keys (to stop the function,
any of the four coarse feed keys can be
pressed).
Coarse feed ‘slow backward’
- Travelling speed 500 µm/s
• To start, press and hold.
Specimen head travels backward (= away
from knife) as long as the key is held.
As long as the backward coarse feed (both fast
and slow) is in motion, the ‘HOME’ LED is illumi-
nated.
Upon reaching the rear limit position, the
‘HOME’ LED starts flashing and the display in
control panel 1 reads ‘HOME’.
Coarse feed ‘fast forward’
- Travelling speed 1,000 µm/s
• To activate the function, press and hold.
The specimen head travels forward (= to-
wards the knife) as long as the key is held.
Coarse feed ‘slow forward’
- Travelling speed 500 µm/s
• To activate the function, press and hold.
The specimen head travels forward (= to-
wards the knife) as long as the key is held.
As long as the forward coarse feed (both fast
and slow) is in motion, the ‘STOP’ LED is illumi-
nated.
Upon reaching the front limit position, the
‘STOP’ LED starts flashing and the display in
control panel 1 reads ‘STOP’.
