Calibration and Troubleshooting
This chapter is to help you resolve any problems you may experience with your LSS-7120
Controller or LSH-7520 LED Head. If you need additional help, please contact Oriel
Instruments Customer Service. See page viii for contact information.
Oriel Instruments provides in-house calibration services. International customers may contact
our services centers for regional calibration support. Oriel factory calibrations employ NIST
traceable measurement instrumentation, and our calibration engineers and technicians use
automated test equipment to accurately and efficiently capture and record calibration data. An
original certificate of calibration authenticity is provided with all instrument calibrations, and a
detailed report showing any pre-calibration out-of-tolerance conditions is available upon request.
Calibration turn-around times are normally five business days or less. Please contact Oriel
Customer Support (see Comments, Suggestions, and Problems on page viii for contact
information) for additional calibration information.
Troubleshooting Guide
This section lists some common problems and corrective actions. In the event that the
corrective action does not resolve problem; please contact Oriel Instruments.
SYMPTOM CORRECTIVE ACTION
The instrument does not power up
Check the power cord to make sure that it is properly connected
and check the wall outlet by connecting to a known operational
device.
The instrument reads “HEd”
The LED head is not connected to the control unit. Check to see
the CC720 is securely connected to both the LSH-7520 head and
the LSS-7120 controller. Tighten the screws on both connectors.
The head does not seem to be putting out
enough power.
Check to see that the head is at the correct working height. See
page 15 – Working Plane Height Adjustment.
OR
The output adjustment is set to below 1.0 sun. Verify the Intensity
CAL button is in the Default mode. See page 12.
The output is a strange color. Not AM1.5G.
Ensure the unit is set to the default AM1.5G output. See page 13 –
Spectrum.
No LEDs seem to be operating Perform the Self Test routine provided in the System software. If
all of the indicators are green the unit is working properly. If the
indicators are RED return to factory for repair.
One or more of the bar graphs are flashing.
This indicates you may have an LED failure in that band. Return
the unit to the factory for repair.
The instrument reads “HOT”.
The temperature of the LED head is above its optimum operating
temperature.
