LASER ON Status output (SK603/7) indicates the current laser status. The output is
decoded as follows:
•
OFF is defined as when the Laser is completely OFF.
•
READY is defined as when the lamp drivers are active up to simmer level.
•
ON is defined as when the lamp drivers are active above simmer level.
REMOTE READY STATUS (SK603/19) is when the Laser is ready and has accepted control
from the PLC.
3.7.4.9 Shutter
Control
Up to four beam paths can be fitted to the laser. The Basic M/C Interface can control up to
two shutters. Shutter commands to shutters that are not fitted to the laser are ignored by the
interface.
The shutters are controlled using ‘Request Shutter’ inputs (SK603 pins 18 & 5).
Note
Any open shutter will be closed on the transition from local to remote control.
After the remote control is granted, a transition of a ‘Request Shutter’ input from false to true
is required to open a shutter. Therefore, if a ‘Request Shutter’ input is true when the laser is
set to remote control, the shutter will not open.
3.7.4.10 Shutter Status
A ‘Shutter Status’ output (SK603 pins 22 & 9) is true to indicate a shutter is open and a
beam path has been selected.
