Status LED’s
v40 LED indicators, also mirrored as output signals on the User I/O connector, provide status in-
formation to the user. Table below shows output signal and LED indicator states during normal and fault
conditions. User I/O outputs are Closed when the state indicated by the signal name is True.
Table 5-2 Status signals
On v40 Keyswitch lasers, the RDY indicator illuminates yellow only when INT and TMP indicators are
green and the Keyswitch is cycled from OFF to the ON position. After the RDY indicator illuminates, a
five-second delay occurs before is permitted to lase. The SHT LED illuminates blue when a Shutter Open
Request signal is applied, and the manual Shutter Switch is set to ON. If the RDY indicator is lit and the
shutter is switched from Closed to Open, there is a five-second delay until PWM inputs are recognized.
When PWM Command pulses are applied (and are long enough to produce laser output) the LASE LED
illuminates red.
On OEM lasers, the RDY lamp illuminates on DC power-up when INT and TMP indicators illuminate green.
After the RDY indicator illuminates, a five-second delay occurs before is permitted to lase. The SHT LED
illuminates blue when a Shutter Open Request signal is applied. If the RDY indicator is lit and then a
Shutter Open Request signal is applied, there is a five-second delay until PWM inputs are recognized.
When PWM Command pulses are applied (and are long enough to produce laser output) the LASE LED
illuminates red.
Important Note: v40 RDY and SHT indicators (as well as Laser Ready and Shutter Open outputs)
denote separate control functions. Although the RDY lamp may light while the SHT LED is Off
(Shutter Switch Closed or Shutter Open Request signal missing), no power is applied to the RF boards
until both RDY and SHT indicators are illuminated.
