The safety door secures the danger zone inside the machine.
The safety door is monitored.
If the safety door is opened during machining, EMERGENCY
STOP will be triggered.
The optoelectronic safety device monitors the area in front of,
behind and below the upper tool during operation by means of a
light field.
The press beam moves at a maximum speed between the
upper dead point and the mute point.If the BendGuard is
pushed up by an obstacle (e.g. trapped hand) or if the light field
is interrupted, then the press beam will stop.
The press beam moves at reduced speed between the mute
point and the lower dead point. The optoelectronic safety device
is not active.
The machine is switched on and off via the main switch. The
main switch can be secured against being switched on again
using a padlock.
The main switch has the following positions:
