16.0. Troubleshooting
If you are unsuccessful at resolving the following conditions, contact SCHOTT North
America, Inc. or your sales representative. See Section 20 for Return Materials
Authorization (RMA) guidance. Do not attempt to repair the Light Source on your own.
Removing the cover will void the warranty.
Problem Reason/Measure
Indicator LED on front panel does not
light up
No power connected to light source.
Indicator LED lights green continuously,
yet LED Light head is dark
Polarity switch in wrong position;
See Section 9.0 “Remote Polarity Switch”
LED indicator LED blinks frequently
Possible LED Over-Temperature, Fan
Fault, or LED driver problem. Try turning
the light source on then off again to see if
problem clears. Use RS-232 or Ethernet to
obtain actual fault condition.
LED light head does not light up when
switched via remote connector
Polarity switch in wrong position;
See Section 9.0 “Remote Polarity Switch”
Communication over Ethernet not
possible even though network jack
lights are flashing
Ensure that the Ethernet communication
settings are correct. Connect to the LLS 3
via an RS-232 link or reset the factory
defaults and connect the unit to a network
with a DHCP server.
Do not attempt to troubleshoot the LLS 3 with any remote control device connected. If
the light source operates after removal of the remote connection, check your remote
set-up.
Note: Opening of the LLS 3 cover prior to the expiration of the warranty period will
invalidate the warranty. Only an authorized repair shop should have access to the light
source with its cover removed.
