An under-voltage condition caused by the DC power supply current limiting can occur if PWM
signals are applied before tube breakdown occurs. On cold starts, verify that tickle pulses are
being sent to the v30 OEM laser for a period of five to ten seconds before a PWM signal is
applied. After correcting the problem, cycle DC power to reset the fault.
Symptom:
•
The following status LED and I/O states exist:
LASE LED – Off
Lase Indicator – Low (0V)
Laser OK – Low (0V)
Voltage OK – Low (0V) RDY LED – Off
Laser Ready – Low (0V)
Temperature OK – High (+5V) PWR LED – 2 blink code
Over-temp Fault – Low (0V) DC Voltage Fault – High (+5V)
Possible Causes:
•
An over voltage fault exists.
An over voltage fault occurs when input voltage rises to 33 VDC or above for more than 420 ms.
Check that the DC power supply is sup30 VDC under load. After correcting the problem,
cycle DC power to reset the fault.
Symptom:
•
The following status LED and I/O states exist:
LASE LED – Off
Lase Indicator – Low (0V)
Laser OK – Low (0V)
Voltage OK – Low (0V) RDY LED – Off
Laser Ready – Low (0V)
Temperature OK – High (+5V) PWR LED – 3 blink code
Over-temp Fault – Low (0V) DC Voltage Fault – High (+5V)
Possible Causes:
•
An DC Sense fault has occurred.
If this fault occurs, the laser requires service—contact NOVANTA Customer Service or a NOVANTA
Authorized Distributor.
Symptom:
•
The following status LED and I/O states exist:
LASE LED – Off
Lase Indicator – Low (0V)
Laser OK – Low (0V)
Voltage OK – Low (0V) RDY LED – Flashing Laser Ready – Low (0V)
