EQ-400 Operation
5.1. Startup
Once the lamp is set up properly, verify that all personnel that will be in contact with the lamp system are
aware of the potential hazards involved. It is the responsibility of the user to verify that the lamp is being used
safely and to consult their laser safety officer for safety measures specific to their use of the source. All safety
measures appropriate for a Class 4 laser product should be taken, including protective eyewear as described
in Section 1.
1. Verify that all interlocks are in place and none of the red fault LEDs on the Controller front panel
are lit. The green POWER OK LED should be lit.
2. Place the keyswitch in the ENABLE position.
3. Turn on the OPERATE Switch (place switch in UP position).
Note:
If the lamp has been on within the last 5 minutes, the POWER OK LED will be flashing and
re-start will not be possible. This is to allow the Lamp to cool down before the next ignition cycle
4. Within several seconds the LASER ON LED will light. Laser light is now present in the Lamp.
5. Within several seconds the igniter will be turned on automatically and the plasma will ignite. The
LAMP ON LED will light. To avoid thermal shock to the Lamp components, the EQ-400 starts with
the laser at half power. After 20 seconds the laser will switch to full power.
5.2. Stopping
The following steps explain the proper procedures stopping
To turn the lamp off, simply turn the OPERATE Switch to the OFF position. It is recommended to turn the
keyswitch to the DISABLE position. The key can be removed if needed for safety or personnel access
reasons. If the lamp will not be used for some time, the AC supply can be turned off.
To minimize wear on the ignition components, it is best to avoid frequently starting and stopping the lamp. It
is recommended to run the lamp continuously if long off-periods are not required.
5.3. Manual Reset
If any fault occurs during operation of the lamp (including actuation of the remote interlock), the laser is
immediately shut off, and light output ceases. When the fault condition is cleared, the lamp will not
automatically restart. The system must be manually reset by turning the OPERATE switch to the OFF
position. Then, assuming that the fault or interlock condition no longer exists, the lamp can be restarted by
turning the switch to the OPERATE position.
If a fault occurs while the lamp is not operating (switch in the OFF position), the switch must be turned to
OPERATE and then back to OFF to clear the fault. The lamp can then be started normally by turning the
switch to OPERATE.
