The dual channel safety critical approach [EN:13849 Performance Level D] requires the system to react
to system conditions as follows:
• When the external
Interlock
is disabled,
User shutter enable
and
RF enable
must
also be disabled by the machine controller.
• When restarting the system with the external
Interlock
enabled, the control signal startup
timing sequence must be followed.
8.5. Status indicators
The operational status of the laser is displayed by status indicator lamps on the laser rear panel.
