16.6 Safe Startup and Shutdown
Sequences
To assure safety during startup, switch on the
components of the laser system in the following
order:
(1) Switch on the network PC.
(2) Switch on the power supply for the
RTC6 Ethernet Board.
(3) Start the control software.
(4) Switch on any required peripheral devices.
(5) Switch on the power supply for the scan system.
(6) Switch on the laser.
To assure safety during shutdown, switch off the
components of the laser system in exactly the reverse
order:
(1) Switch off the laser.
(2) Switch off the power supply for the scan system.
(3) Switch off the peripheral devices.
(4) Terminate the control software.
(5) Switch off the power supply for the
RTC6 Ethernet Board.
(6) Shut down the network PC.
Caution!
• When the PC switches on or off, the
RTC6 Ethernet Board board output ports levels
might briefly fluctuate, resulting in unintended
changes to Laser Control Signals. The above-
mentioned startup and shutdown sequences
must therefore be strictly followed. Otherwise,
the laser might briefly, unexpectedly and
dangerously switch on.
• Always start up the PC and control software
prior to turning on the scan system. And switch
the scan system back off prior to shutting down
the control software and PC. Otherwise,
unintended scan system motions might occur.
The laser must always be switched on last and
switched off first. Otherwise, there is the risk
that the laser beam might be deflected in an
arbitrary direction.
