Beam Delivery Optics - Novanta vi30 User Manual

BEAM DELIVERY OPTICS

Under voltage faults are typically caused by the DC power supply being unable to properly regulate
output voltage under full-load or high inrush current conditions. Improper regulation may be caused by
an undersized DC supply or insufficient AC line voltage.
Over Voltage fault
An over voltage fault occurs when the DC input voltage is at or above 52 VDC. This fault is indicated by
the PWR indicator flashing 2 blinks at 1/2 second intervals. To reset an over 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.
DC Sense fault
An DC Sense fault is indicated by the PWR indicator flashing 3 blinks at 1/2 second intervals. If this fault
occurs, the laser requires service—contact NOVANTA or a NOVANTA Authorized Distributor.
PWM Sense/Control Board fault
A PWM Sense or control board fault is indicated by both RDY and PWR indicators flashing continuously.
If this fault occurs, the laser requires service—contact NOVANTA or a NOVANTA Authorized Distributor.
Symptom:
•
The power supply is connected, and the voltage is correct, but the PWR LED is not on.
Possible Causes:
•
The fast-acting fuse has blown.
To replace the fuse, open the in-line fuse holder by twisting the upper half 1/4 turn counter-clockwise.
Remove the fuse and replace it with an appropriate fast-acting fuse (see Operation and/or Getting
Started Chapter for more vi30/40 fuse replacement information).

Symptom:
•
The laser loses 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
