Troubleshooting Guide
If a problem is suspected, first try recalibrating the luminaire to prompt an error message. Table A-2
below provides possible causes and remedies for various error messages and/or symptoms.
CAUTION: Some troubleshooting is included for reference only. Performing remedies marked by
gray areas will void product warranty. Refer to the Vari-Lite Limited Warranty card included with the
product.
Note: *The nature of the CDM lamp used in the VL1100CD ERS Luminaire prevents it from
restriking when it is hot after use. It takes approximately 15 minutes for the lamp to cool enough to
restrike.
