6. As soon the DC power supply is energized, the master power button (top right) will automatically
light up.
The light engine automatically starts when the power is connected; there is no need to
push the master power button
.
7. Wait 30–45 seconds for the initiation sequence (onboard microprocessor boot-up) to complete.
Do not press any buttons or insert any plugs during this time.
8. When the initiation sequence completes, “LUMENCOR” will flash on front display panel and then
be replaced by a display showing the current light engine IP address, the internal temperature
and the fan status.
At the same time, the fan will come on at HI for about 2 seconds and then
shut o
ff
automatically. The light engine is now ready for use. Prior to turning the light output on,
be sure the output end of the liquid light guide or optical fiber is safely directed into an enclosed
optical path (e.g. a beam dump).
Notes:
1
Ensure that the distal end of the light guide or optical fiber is safely directed into an enclosed
optical path (e.g. microscope epilluminator or a beam dump) before turning the light output on. If
the light engine is equipped with an output adapter for an SMA-terminated optical fiber, connect the
fiber to the output adapter using the integral threaded sleeve.
2
To enable light output of the RETRA (L) Light Engine the external gate jumper, control key, remote
interlock jumper, and Liquid light guide must be inserted.
3
For subsequent start ups, use the master power button to start or shut down the light engine.
Shut down can also be accomplished using the “Shut Down” button in the GUI (Figure 5, left).
3.3.3 Ethernet Connection and Control GUI
The Web GUI provides a quick and easy way to control the light engine, providing the ability to turn
each source on/o
ff
(Figure 4, Control Tab [left], 2), adjust the power of each source independently
from o
ff
to full power (Figure 5, Control Tab [left], 3). The GUI also tracks the total on time (Figure 5,
Settings tab [right], 13) and the power sensor readings (Figure 5, Control tab [left], 4). To set up the
Web GUI, follow the follow protocol below:
1. Go to Start menu > Control Panel > Network & Internet and/ or Network & Sharing Center
2. Click Change Adapter Settings
3. Right-click on Local Area Connection
4. Click on Properties (in pop-up)
5. Select Internet Protocol Version 4 (TCP/IPv4)
6. Click Properties button
7. Use the following IP addresses:
•
IP Address: 192.168.201.201
•
Subnet Mask: 255.255.255.0
•
Default gate way and DNS Server are OK to leave blank
