Troubleshooting
Status LEDs
Pulstar p100 LED indicators, also mirrored as output signals on the
User I/O
connector, provide status
information to the user. Table 4-2 shows Pulstar 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 logically True.

On DC power-up of an OEM p100 laser, the RDY lamp illuminates yellow when INT and TMP indicators
illuminate green. The SHT LED illuminates blue when a Shutter Open Request signal is applied. When
both RDY and SHT indicators are lit, the RF driver is enabled and internal tickle is applied. Once the RF
driver is enabled, the application of a PWM Command signal causes the LASE indicator to illuminate red
as lasing begins.
Note: Pulstar p100 RDY and SHT LEDs denote separate control functions. Although the RDY lamp
may light while the SHT LED is Off ( Shutter Open Request signal missing), no power is applied
to the RF driver until both RDY and SHT indicators are illuminated.
