Troubleshooting
Shutter
A closed shutter is not considered a fault condition. When the shutter is opened (or a Shutter
Open Request signal is applied), lasing is enabled after a ve-second delay provided that the
RDY indicator is illuminated yellow.
Under/over voltage fault
An under voltage or over voltage fault occurs when the DC input voltage is below or above
preset limits. This fault is indicated by the RDY indicator ashing 1 blink (under voltage) or
2 blinks (over voltage). To reset an under voltage or over voltage fault, ensure that 30 VDC
is applied to the laser under full load conditions, cycle DC power o and on, and then toggle
the Keyswitch from OFF to ON (or apply a ±5–24 VDC Remote Reset/Start Request pulse
with the Keyswitch set to ON). When the RDY indicator illuminates, lasing is enabled after a
ve-second delay.
RF Drive DC fault
An RF Drive DC fault is indicated by the RDY indicator ashing 3 blinks. Reset the laser by
removing DC power to the laser, wait 30 seconds, and then reapply DC power. If the RF Drive
DC fault reappears, contact SYNRAD or a SYNRAD Authorized Distributor.
PWM Drive fault
A PWM Drive fault is indicated by the RDY indicator ashing 4 blinks. Reset the laser by
removing DC power to the laser, wait 30 seconds, and then reapply DC power. If the PWM
Drive fault reappears, contact SYNRAD or a SYNRAD Authorized Distributor.
OEM lasers
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 inict 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.
Remote interlock fault
A remote interlock fault occurs when the Remote Interlock input opens (the INT indicator
changes from green to red). On OEM lasers, remote interlock (INT) faults are not latched.
Re-establish the Remote Interlock signal input (INT indicator changes from red to green) to
enable the RDY indicator and begin lasing after the ve-second delay.
