RESETTING FAULTS PAGE | 83
Over temperature fault
Over temperature faults occur when thermal limits in the laser are exceeded. This fault is indicated by
the RDY indicator flashing 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
illuminates without flashing, lasing is enabled.
Under Voltage fault
An under-voltage fault occurs when DC input voltage is at or below 20 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 30
VDC is applied to the laser under full-load conditions and then cycle DC power. When PWR and RDY
indicators illuminate, lasing is enabled.
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 to the supply.
Over Voltage fault
An over voltage fault occurs when DC input voltage is at or above 33 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 30
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.
