Your control system can monitor the laser’s shutter status on the User I/O connector by connecting your
system’s input to Pin 14, Shutter Open, and Pin 13, Output Common (see Output Signal section and
Figures above). The Shutter Open output closes when a Shutter Open Request signal is present (SHT
LED illuminated blue), and the Laser Ready output is closed (RDY LED is On). The output is open (SHT
LED Off) when the Shutter Open Request signal is removed, or the Laser Ready output is open (RDY
LED is Off).
Remote interlock functions
Interlock circuits are often used to disable machinery when a shield, panel, or door is opened. P250’s
remote interlock function allows you to connect into an external remote interlock circuit and prevent
lasing by removing DC power from the laser’s RF driver boards when the circuit is electrically “open”.
Lasing is enabled when a Remote Interlock signal is present (INT LED illuminated green), if the RDY LED
is illuminated and a Shutter Open Request signal is applied. Lasing is disabled when the Remote Interlock
signal is removed (INT LED red, RDY LED off). DC power is applied to the RF driver only when the INT
LED is green and the RDY LED is yellow. Remote interlock functionality is provided by the Remote
Interlock signal via Pin 3 on the User I/O connector.
To use P250’s remote interlock feature to initiate lasing, apply a voltage in the range of ±5–24 VDC to
Pin 3, Remote Interlock. Applying a Remote Interlock signal causes the INT LED to turn green, the RDY
indicator to turn yellow, and sends DC power to the laser’s RF boards. After a five-second delay, a tickle
signal is applied to the tube. When a Shutter Open Request signal is present, PWM Command signals are
enabled to begin lasing. Removing voltage stops DC power from reaching the RF driver, causing the INT
LED to turn red and the RDY LED to turn Off. Lasing remains disabled until a voltage is reapplied to Pin
3.
Your control system can monitor the laser’s remote interlock status on the User I/O connector by
connecting your system’s input to Pin 15, Interlock Open, and Pin 13, Output Common (see Figures
above). This output is closed when remote interlock circuitry is open (INT LED illuminated red). The
output is open (INT LED green) when interlock circuitry is closed.
