2.9 Troubleshooting
Troubleshooting of a Chroma-Q is aided by the indications provided by the 3 diagnostic LED's
visibly through the Chroma-Q body. All troubleshooting procedures should begin with a LED
check.
The power supplies are designed to shut down if their outputs are shorted. They will not reset
until the AC supply has been disconnected and reconnected. The power supply red LED is an
indicator of output Voltage not input Voltage.
Note:
A high percentage of problems are caused by corrupt DMX control protocol. We highly
recommend the use of genuine Tourflex Datasafe cables for all Chroma-Q colour changer and
DMX control protocol cables.
