    Getting Started Use information in this section to prepare your f201 laser for operation. The order of information presented in this section is the same as the order of tasks that you will need to perform. The best way to get your laser ready for operation is to start at Unpacking and work your way through Connecting.

  • Page 11: Introduction

    Keyswitch and OEM models available. f201 Nomenclature f201 lasers are available only as OEM lasers; they do not include either a keyswitch or manual shutter assembly. NOVANTA’s OEM lasers are primarily designed as components for integration into larger processing systems by the Original Equipment Manufacturer (OEM) or System Integrator who bears the responsibility for meeting the appropriate laser safety requirements for Class 4 laser systems.

    Packaging guidelines Warning: Serious Personal Injury Lifting or moving f201 lasers poses a potential for injury. Use appropriate lifting techniques and/or equipment to prevent a risk of injury. In some cases, you may require assistance from additional personnel to safely unpack and move this equipment.

  • Page 13: Figure 2-1 Unpacking The Laser

    Important Note: All f201 lasers are water-cooled because of the integrated RF section’s heat removal requirements. f201 lasers cannot be fan cooled. Damage to your laser will void your warranty.

  • Page 73: Integrating F201 Laser Safety Features

    F201 laser’s keyswitch, shutter, and remote interlock functions serve to enable or disable DC power to F201 laser’s RF drive. Without DC power, the RF driver cannot supply RF energy to the resonator, causing the gas to remain in a zero-energy state.

    Remote Interlock input signal on Pin 3 of the User I/O connector. To use F201 laser’s remote interlock feature, apply a voltage in the range of ±5–24 VDC to Pin 3, Remote Interlock. Applying an interlock signal causes the Remote Interlock LED to illuminate green and sends DC power to the RF driver, which enables lasing after a five-second delay (provided that the Ready LED is yellow, and the Shutter LED is blue).

  • Page 75: Integrating F201 Safety Features

    The f201 DB-9 Connector allows system integrators or end-users to integrate f201 laser safety features into their control system. In particular, the f201 Remote Keyswitch function serves to disable DC power to the laser’s RF driver. Without power, the RF driver cannot supply PWM or tickle signals to the resonator, causing the CO2 gas to remain in a zero-energy state.

  • Page 91: Troubleshooting

    Over-temperature faults are now latched. To reset an over-temperature fault, lower coolant temperature below 28 °C (f201) to cool the laser and then cycle DC power to the laser. Once the Temp indicator is green and the Ready lamp is lit, lasing is possible after the five-second delay.

  • Page 92: Other Laser Faults

    If the RF Drive DC fault reappears, contact NOVANTA or a NOVANTA Authorized Distributor. PWM Drive/RF Oscillation faults New circuitry on the f201 RF board has eliminated PWM Drive and RF Oscillation faults. The 4-blink fault indication no longer exists. VSWR fault A VSWR fault indicates an impedance mismatch between the tube and RF Driver and occurs when a PWM Command signal is first applied.

  • Page 96: Beam Delivery Optics

    If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high power density of F201 laser lasers, pits or debris on the lens surface may absorb enough energy from the focused beam to crack the lens. If this happens, other optics in the beam path may be contaminated or damaged as well.
