Troubleshooting (cont.)
Symptom:
■ The
PWR
indicator blinks three times, pauses 1/2 second and repeats. Both
RDY
and
LASE
LEDs are Off. On the
Interface A
(DB-9) connector, Lase Indicator , Laser Ready , and Overtemp Fault outputs are Low, but the DC Voltage
Fault output is High. On the
Interface B
(RJ45) connector, the Temperature Ok signal is High while the Laser Ok and
Voltage Ok outputs are Low.
Possible Causes:
■ A DC Sense fault has occurred.
Remove DC power from the laser, wait 30 seconds, and then re-apply DC power. If the fault fails to clear, contact SYNRAD
or a SYNRAD Authorized Distributor.
Symptom:
■
Both PWR and RDY indicators are flashing. 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 Temperature Ok and Voltage Ok outputs are High while the Laser Ok signal is Low.
Possible Causes:
■ A PWM Sense fault has occurred.
Remove DC power from the laser, wait 30 seconds, and then re-apply DC power. If the fault fails to clear, contact SYNRAD
or a SYNRAD Authorized Distributor.
DB-9 connector
Symptom:
■ The built-in +5 VDC, 250 mA voltage output on Pin 5,
DC Out
, has been accidentally shorted to ground.
Possible Causes:
■ In the event that Pin 5, DC Out , is shorted to ground, the OEM v30 laser will not be damaged as the voltage regulator
is protected by a current-limiting circuit.
RJ45 connector
Symptom:
■ The built-in +15 VDC, 250 mA voltage output on Pin 2,
DC Out
, has been accidentally shorted to ground.
Possible Causes:
■ In the event that Pin 2, DC Out is shorted to ground, the OEM v30 laser will shutdown, but restarts automatically
once the short-circuit is removed.
Beam delivery optics
Symptom:
■ The laser appears to lose power over time; laser output power must be increased to maintain previous performance.
Possible Causes:
■ Beam delivery optics are coated by vapor residue or debris.
