Troubleshooting
Other laser faults
When a laser fault occurs, Firestar’s status LEDs and output signals will reect a fault condition as in-
dicated in the prior tables. Each Symptom listed below describes a particular fault condition. For each
Symptom, specic causes and solutions are described under Possible Causes.
Warning
serious
personal
injury
On Firestar v40 OEM lasers, remote interlock (INT) faults are not
latched. Clearing the fault condition re-enables the RDY indicator
and the laser will re after the ve-second delay provided that the
SHT indicator is lit and a PWM Command signal is applied. Because
exposure to 10.6 µm CO
2
laser radiation can inict severe corneal
injuries and seriously burn human tissue, the OEM or System Integra-
tor must ensure that appropriate safeguards are in place to prevent
unintended lasing.
Symptom:
■ A remote interlock fault is indicated:
INT LED – Red Interlock Open – Closed
TMP LED – Green Over Temperature – Open
RDY LED – O Laser Ready – Open
SHT LED – Blue Shutter Open – Closed
LASE LED – O Laser Active – Open
Possible Causes:
■ No voltage applied to Pin 3 (Remote Interlock) on the User I/O connector.
On systems using remote interlocks, check to see that a positive or negative voltage (±5–24 VDC) is ap-
plied to Pin 3, Remote Interlock, with respect to Pin 11, Input Common, on the User I/O connector (re-
fer to User I/O connections in the Technical Reference chapter for details). For systems not using interlocks,
connect the factory-supplied Quick Start Plug to the User I/O connector on the laser’s rear panel or wire
your male DB-15 connector so that Pin 11 (Input Common) is jumpered to Pin 12 (Auxiliary DC Power
Ground) and Pin 3 (Remote Interlock) is jumpered to Pin 4 (+5 VDC Auxiliary Power).
Symptom:
■ An over temperature fault is indicated:
INT LED – Green Interlock Open – Open
TMP LED – Red Over Temperature – Closed
RDY LED – O Laser Ready – Open
SHT LED – Blue Shutter Open – Closed
LASE LED – O Laser Active – Open
