Troubleshooting

Problem: On initial start up, no light output from Lumen200 / S / Pro.
Suggested Solutions:
• Confirm unit is plugged in and there are no error codes on front display.
• Confirm that the light output knob is not rotated to the 0% position (Lumen200 &
Lumen200S).
• Check shutter position (Lumen200S & Lumen200PRO only) position to confirm if it is in
the fully closed position.
Lumen200S – Look at the LED display on the front of the Lumen200S check the condition.
S – reports shutter is CLOSED; O – reports shutter is OPEN.
Lumen200Pro - This can be done by sending the "LIGHT" command in HyperTerminal.
See ProScan, OptiScan or PriorPCI manual for instructions on using "HyperTerminal".
• Send "HOME" command to filter wheel (L200PRO only) to insure it is not obstructing the
optical path. Confirm that filter position in the light path does not contain a blanking plate.
Problem: On initial start up, illumination is not bright.
Suggested Solutions:
• The unit requires 5 mins to warm up and 15-30mins to reach full brightness.
• Check that Liquid Light Guide is installed correctly, see section 4 for installation
instructions.
• Check that bulb is installed correctly. Check the appropriate installation instructions for the
device you have. (Note, you must wait 30 minutes after shutting off the illuminator before
opening the access panel.)
Problem: Just changed bulb and light is significantly less than normal.
