Novanta v40 User Manual page 44

INITIAL START-UP (CONTINUED)
2 Place the Shutter Switch (if equipped) in the Open position. The blue SHT (Shutter) indicator will
3 illuminate.
4 Rotate the Keyswitch (if equipped) to the ON position. Verify that the yellow RDY (Ready) lamp
illuminates.
Important Note: Each time an OEM laser is powered up or a Keyswitch version is cycled OFF/ON,
a five-second delay occurs between the time that RDY and/or SHT indicators illuminate and v40 is
permitted to lase.
Because of phase differences, external tickle pulses may combine with the internally generated tickle
signal causing the LASE LED to flicker during the transition from tickle to lasing. Laser output may
occur if the Lase LED flickers.
Important Note: For remote operation (Keyswitch lasers), it is possible to set the Keyswitch to
the ON position and use the Remote Reset/Start Request signal (on the User I/O connector) as a remote
keyswitch, similar to other NOVANTA laser models.
5 Press the UC-2000's Lase On/Off button. The Lase indicator on the UC-2000 should illuminate.
6 Use the PWM Adj Knob on the UC-2000 to slowly increase power. The LASE LED turns red when
PWM signal pulses are long enough to produce laser output (typically 5–10 μs at 5 kHz). The spot
where the beam hits the beam block increases in brightness to indicate increased power output.
7 Press the UC-2000's Lase On/Off button to stop lasing. Lase indicators on the UC-2000 and the
laser should both turn off.
8 Place 's Shutter Switch (if equipped) in the Closed position.
9 On water-cooled v40 lasers, shut off the chiller or otherwise stop coolant flow through the laser.
Do not flow coolant through the laser for an extended period of time when the laser is shutdown. This
causes condensation to form inside the laser which may result in catastrophic damage to internal
optics and electronic circuits.
If your v40 laser fails to lase, refer to Troubleshooting in the Maintenance/Troubleshooting chapter for
troubleshooting information.
Warning: Serious Personal Injury
Caution: Possible Equipment Damage
