Resetting Faults - Novanta vi30 User Manual

RESETTING FAULTS

OEM vi30/40 LED indicators, in conjunction with the DB-9 I/O outputs, provide status information to the
user. The prior table shows LED indicator and output signal states during normal and fault conditions.
On OEM vi30/40 lasers, the PWR indicator illuminates green on DC power-up. The RDY LED illuminates
yellow when a Laser Enable signal is applied and after a five-second delay, customer-supplied tickle
signals are passed through to the RF driver. When PWM Command pulses are applied (and are long
enough to produce laser output) the LASE LED illuminates red.
Laser fault indications
OEM vi30/40 lasers can indicate five specific 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.
Ensure that DC power to the laser is turned off and locked out before inspecting optical components
in the beam path. Invisible CO
blindness may result from exposure to laser radiation.
Resetting faults
Over temperature fault
Over temperature faults occur when thermal limits in the laser are exceeded (RDY indicator flashes
continuously; PWR LED remains solid green). To reset an over temperature fault, cool laser chassis
temperature below 60 °C and then cycle DC power. When the RDY LED illuminated without flashing,
lasing is enabled.
Under Voltage fault
An under-voltage fault occurs when the DC input voltage is at or below 45 VDC. This fault is indicated
by the PWR indicator flashing 1 blink at 1/2 second intervals. To reset an under voltage fault, ensure that
48 VDC is applied to the laser under full-load conditions and then cycle DC power. When PWR and RDY
indicators illuminate, lasing is enabled.
Warning: Serious Personal Injury
laser radiation is emitted through the aperture. Corneal damage or
