  • Page 37: Setting Coolant Temperature

    3.4.2.5 Setting Coolant Temperature Choosing the correct coolant temperature is important to the proper operation and longevity of your laser. When coolant temperature is lower than the dew point (the temperature at which moisture condenses out of the surrounding air), condensation forms inside the laser housing leading to failure of laser electronics as well as damage to optical surfaces.
  • Page 38 3.4.2.6 Table: Dew Point Temperatures The laser’s coolant temperature must be set above the dew point temperatures shown in the chart but should not exceed 22 °C (72 °F). Relative Humidity Temp 20% 25% 30% 35% 40% 45% 50% 55% 60% 65% 70% 75% 80% 85% 90% 95% °F/°C 60 °F 16 °C...

  • Page 39: Cooling Tubing Connections

    Relative Humidity columns is the Dew Point Temperature. The chiller’s temperature setpoint must be above the dew point temperature. For example, if the air temperature if 85°F (29°C) and the relative humidity is 60%, then the dew point temperature is 70°F (21°C). Adjust the chiller’s temperature setpoint to 72°F (22°C) to prevent condensation from forming inside the laser.

  • Page 82: Status Indicator Leds

    5.2.3 Status Indicator LEDs Three status indicator LEDs on the rear of the vi Series laser provide a visual indication of operating status. A green PWR LED illuminates when DC power is applied to the laser. The yellow RDY LED indicates that a Laser Enable signal has been applied and that, after a five- second delay, lasing will begin once a PWM Command signal is received.

    5.2.6 Resetting Faults 5.2.6.1 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.

    5.2.7 Other Laser Faults When a laser fault occurs, the status LEDs and output signals will reflect a fault condition as indicated in the previous table. Each Symptom listed below described a particular fault. For each Symptom, specific causes and solutions are described under Possible Causes. Symptom: The following LED and I/O states exist: LASE LED = Off Lase Indicator output...
  • Page 86 Possible Causes: An under voltage fault exists • An under voltage fault occurs when input voltage drops below 45 VDC for more than 420 ms. Check that the DC power supply is supplying +48 VDC under load and that its current capacity is 10 amperes or greater.
  • Page 87 Symptom: The following LED and I/O states exist: LASE LED = Off Lase Indicator output = Low (0V) • RDY LED = Flashing Laser Ready output - = Low (0V) • PWR LED = Flashing • Over Temp Fault output = Low (0V)) •...

  • Page 88: Beam Delivery Optics

    5.2.8 Beam Delivery Optics Warning: Serious Personal Injury The use of aerosol dusters containing difluoroethane causes “blooming,” a condition that significantly expands and scatters the laser beam. This beam expansion can affect mode quality and/or cause laser energy to extend beyond the confines of optical elements in the system, damaging acrylic safety shielding.
  • Page 89 Warning: Serious Personal Injury A risk of exposure to toxic elements, like zinc selenide, may result when certain optical or beam delivery components are damaged. In the event of damage to the laser, marking head, or beam delivery optics, contact Novanta or the optics manufacturer for handling instructions. If the focusing optic is pitted, it must be replaced immediately.
