REMOTE INTERLOCK FUNCTIONS PAGE | 59
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 ’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 Figure 4-25).
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.
