Laser fault indications
OEM v30 lasers have the ability to indicate ve specic fault conditions. In the event of certain faults, the
RDY LED, PWR LED, or both will blink an error code, pause 1/2 second, and then repeat the code. This
sequence continues until the fault is corrected and the laser is reset by cycling DC power to the laser.
Table below lists fault codes, the corresponding fault condition, and describes possible corrective ac-
tions.
Table 5-14 Laser fault codes
LED # of Blinks Fault Condition Corrective Action in Field
RDY Continuous Over Temperature fault Cool laser and then cycle DC power
PWR 1 blink Under Voltage fault Verify 30 V (under load) and cycle DC power
PWR 2 blinks Over Voltage fault Verify 30 V (under load) and cycle DC power
PWR 3 blinks DC Sense fault Contact SYNRAD Customer Service

Resetting faults
Remote interlock condition
A remote interlock condition occurs when the Laser Enable input opens (the RDY indicator turns o).
On OEM lasers, remote interlock conditions are not latched. Re-establish the Laser Enable signal input
(RDY LED changes from o to yellow) and begin lasing immediately.
Over temperature fault
Over temperature faults occur when thermal limits in the laser are exceeded. This fault is indicated by the
RDY indicator ashing continuously). To reset an over temperature fault, lower coolant temperature below
22 °C (water-cooled) or 40 °C (air-/fan-cooled) and then cycle DC power. When the RDY LED illumi-
nates without ashing, lasing is enabled.
