5.4.3 Selecting sectioning speed
Sectioning speed is selected via the sliding
potentiometer. Speed can be changed while
sectioning is in motion.
Caution when working in continuous mode:
If the slider is set to ‘0’, the sectioning motion
stops, however, the actual sectioning mode is
still active - just operating at ‘0’ speed.
If the slider is accidentally moved, sectioning
will be resumed! - Risk of injury!
Therefore:
Do not interrupt sectioning / trim-
ming by setting the sliding potenti-
ometer to zero speed!
See also safety instruction in Chap-
ter 2.3.6 ‘Motorized sectioning’.
Vmax key
As long as the button is pressed, the
sectioning motion is carried out at maxi-
mum speed (210 mm/s).
While Vmax is active, the sectioning window is
inactive.
When the Vmax key is released, the sectioning
window becomes active again.
5. Operation
5.4.4 Emergency stop
Activate by:
either pressing the emergency stop
button forcefully (must lock in
position),
or depressing the footswitch force-
fully.
Either way, sectioning is interrupted at once.
In both cases, the red LED in functional
area A lights up, indicating that the emergency
stop function has been activated. Simultaneously
all 3 sectioning modes are deactivated
(= all 3 LEDs off).
To deactivate the emergency stop function,
rotate the button in the direction of the ar-
row until it unlocks and slips upward into its
original position.
As soon as the emergency stop button has been
unlocked, the red LED is extinguished.
If the emergency stop function has been ac-
tivated with the footswitch, unlocking is not
necessary.
As soon as the footswitch is released, the red
LED is extinguished.
To continue work, select one of sectioning
modes 1 - 3 and restart the sectioning
motion.
See also chapter 2.2.3 ‘Safety - Emergency stop
function’ for further information on the emer-
gency stop.
