Setup the Lamp House unit with appropriate ultraviolet safety measures and laser light
safety measures in place. It is recommended that any enclosure or aperture-blocking
hardware utilize switches wired to the EQ-400 remote interlock circuit.
See drawing OTD-8159 in Appendix A for mechanical details of the Lamp House.
3.
Connect the laser fiber to the Lamp House as follows:
WARNING
The collimator must never be detached from its mounting bracket.
Doing so could allow dangerous invisible laser radiation to be emitted.
a.
Remove plastic cap from the end of the laser collimator
Note: always keep this cap in place when the laser fiber is
not connected to the Lamp House.
b.
Inspect collimator lens for dust or contamination
c.
Insert the collimator and bracket into the socket in the Lamp House
d.
Secure the bracket to the Lamp House using the four socket head screws and a
3mm hex driver. Torque the screws to 20 in-lbs.
4.
Connect the 9-pin D-sub interconnect cable from the Power/Control Unit to the
Lamp House.
5.
Connect nitrogen purge gas to the 4mm push-to-connect fittings on the Lamp House.
6.
Connect cooling water to the 8mm Swagelok fittings on the Lamp House.
7.
Connect cooling water to the 8mm push-to-connect fittings on the rear of the PCU.
8.
Connect an interlock switch or jumper plug (supplied) to the interlock pins of the
remote I/O connector (functions as remote interlock connector).
9.
If using remote control mode, connect user’s control system to the remote I/O
connector using a suitable cable.
Table 3 gives the pin assignments and functions for the remote interface. Mating
connector is a standard high-density 15-pin d-sub male (for example, Amp part no.
748364-1 with contacts 1658670-2).
User I/O can be powered either by the EQ-400 internal isolated power supply, or an
external supply. Figure 5 shows connection schematics for both configurations.
10.
If using the optional RS-485 interface, connect the host computer to the RS-485
connector on the rear of the PCU. Mating connector is a standard 9-pin female d-sub
(for example, AMP part no. 205203-3 with contacts 1-66504-0). See Table 4 for pin
connections.
11.
Connect an AC input power source to the standard IEC 320 style inlet on the rear of
the PCU.
