Keyswitch functions  

 

Keyswitch lasers  

After DC power-up or after a remote interlock fault, the Keyswitch must be toggled to reset the laser 

and enable the RDY LED, signaling that DC power is applied to the RF driver. Over temperature faults 

are reset by removing, then reapplying DC power after the laser has cooled.  
For Keyswitch lasers used in automated systems, this reset function is provided by the Remote Reset/ 

Start Request signal via Pin 2 on the User I/O connector. To use this “remote keyswitch” functionality, 

first place the Keyswitch in the ON position. To reset a fault condition, apply a ±5–24 VDC signal to Pin 2, 

Remote Reset/Start Request, and Pin 11, Input Common. Removing the signal applies power to the RF 

driver causing the RDY lamp to illuminate and begins a five-second countdown after which lasing is 

enabled. The RF driver is disabled as long as a ±5–24 VDC signal is applied to Pin 2.  
Your control system can monitor the laser’s ready status on the User I/O connector by connecting your 

system’s input to Pin 8, Laser Ready, and Pin 13, Output Common (see output driving PLC input module  
Figure 4-16). The Laser Ready output closes when the laser is enabled (RDY LED illuminated yellow), 

indicating that lasing is possible. The output is open (RDY LED off) when lasing is disabled.  
 

 

Important Note: A five-second delay occurs between the time the Laser Ready output closes and 

lasing is enabled.  
 

OEM lasers  

On OEM lasers, the RDY LED illuminates on DC power-up (provided that Shutter Open Request and 

Remote Interlock inputs are enabled) and five seconds later DC power is applied to the RF driver. Over 

temperature faults are reset by removing and then reapplying DC power after the laser has cooled. 

Remote interlock faults are not latched; the RDY LED illuminates yellow as soon as the interlock circuit is 

closed (when the INT LED turns from red to green) and five seconds later lasing is enabled.  
Although a Remote Reset/Start Request input is not needed to reset OEM faults, it can be used to inhibit 

(disable) lasing. Disable the laser by applying a ±5–24 VDC signal to Pin 2, Remote Reset/Start Request, 

and Pin 11, Input Common. Removing the signal applies power to the RF driver causing the RDY lamp to 

illuminate and begins a five-second countdown after which lasing is enabled. The RF driver is disabled as 

long as a ±5–24 VDC Remote Reset/Start Request input is applied.  
Your control system can monitor the laser’s ready status on the User I/O connector by connecting your 

system’s input to Pin 8, Laser Ready, and Pin 13, Output Common (see prior table). 
The Laser Ready output closes when the laser is enabled (RDY LED illuminated yellow), indicating that 

lasing is possible. The output is open (RDY LED off) when lasing is disabled.  
 

 

Important Note: A five-second delay occurs between the time the Laser Ready output closes and 

lasing is enabled.
