Override Of Shutter Lockout - Continuum Surelite I 10 Operation And Maintenance Manual

Continuum Surelite Laser

Override of shutter lockout

For reliable operation and spec. performance of the Surelite laser, key components on the laser
system are thermally stabilized. To ensure that thermal stabilization has been reached at initial
startup, there is a 20 minute period after ac power is first applied before the SHUTTER button
can be toggled open.
Attempts to toggle the SHUTTER button open before this 20 minute period has expired will
only result in the power supply beeping each time the SHUTTER button is pressed. If during
the course of daily operation of the laser, there is a momentary interruption in ac power (<5
minutes), it is possible to resume operation immediately without having to wait for 20 minutes.
This is done by performing the procedure below. However, do NOT use this override unless it is
certain that thermal stabilization has been restored.
1. On the front panel of the Surelite power unit, flip red toggle switch labeled AC POWER
down (this is the OFF position).
2. Depress simultaneously the START/STOP button, the SHUTTER button and the
ARROW DOWN button.
3. While depressing simultaneously the 3 buttons, flip the red toggle switch labeled up to the
ON position.
4. Continue depressing the three buttons until the LED display reads oFF.
5. Insert the key into keyswitch and turn counter clockwise to ON.
6. Press START/STOP button and its red LED comes on. The laser head will now flash at
the designated frequency.
7. Put on laser safety goggles.
8. Press the SHUTTER button and its red LED comes on. An audible click can be heard
from laser bench as the intra-cavity shutter withdraws from the oscillator. The system
should now lase.

CAUTION!

been reached will result in serious damage to your
laser system.
