Error codes
Firestar OEM v30 lasers have the ability to indicate various laser faults by flashing RDY and PWR indicators. For OEM v30
lasers manufactured after October 1, 2011, certain faults are annunciated by the PWR LED blinking an error code, pausing
1/2 second, and then repeating the error code. This sequence continues until the fault is corrected and the laser is reset by
cycling DC power. Table 10 lists error codes, the corresponding fault condition, and describes possible corrective actions.
Table 10 Firestar v30 error codes
LED # of Blinks Fault Condition Corrective Action in Field
RDY Off
PWR 1 blink Under-Voltage fault Verify 30 VDC (measured at laser under load)
RDY Off
PWR 2 blinks Over-Voltage fault Verify 30 VDC (measured at laser under load)
RDY Off
PWR 3 blinks DC Sense fault Remove DC power, wait 30 seconds, and then re-apply power.
RDY Continuous
PWR On Over temperature fault

Cool laser and then cycle DC power.
RDY Continuous
PWR Continuous PWM Sense fault Remove DC power, wait 30 seconds, and then re-apply power.
1 An over temperature fault is indicated if the Overtemp Fault output is high (+5 V). If the Overtemp Fault output is low, then a control board failure
may have occurred.
Laser faults
When a fault occurs, status LEDs and output signals reflect faults as indicated in Table 8, Table 9, or Table 10. Each Symp-
tom listed below describes a particular fault and specific causes and solutions are described in the Possible Causes section.
Symptom:
■ The RDY indicator is Off. The PWR LED is green and the LASE LED is Off. On the Interface A (DB-9) connector, all
outputs (Lase Indicator, Laser Ready, DC Voltage Fault, and Overtemp Fault) are Low. On the Interface B (RJ45)
connector, the Laser Ok signal is Low while Voltage Ok and Temperature Ok outputs are High.
Possible Causes:
■ No Laser Enable input signal is present.
A 5V logic level Laser Enable signal must be applied to enable lasing. On the Interface A (DB-9) connector, apply the en-
able signal between Pin 9 and Pin 8. On the Interface B (RJ45) connector, apply the enable signal between Pin 7 and Pin 8.
Symptom:
■ The RDY LED is flashing. The PWR LED is green and the LASE LED is Off. On the Interface A (DB-9) connector,
Lase Indicator, Laser Ready, and DC Voltage Fault, outputs are Low, but the Overtemp Fault output is High. On the
Interface B (RJ45) connector, the Voltage Ok signal is High while Laser Ok and Temperature Ok outputs are Low.
Possible Causes:
■ An over temperature fault exists.
