I am so glad to have found this forum and I am looking forward to gaining much needed help/advise with my wife’s drama, choir, and band programs. She has a new job at a rural school here in Colorado, which has a nice stage with an incandescent lighting system. It has three NSI DDS8600 dimmers that are not working quite right. From what I have read on this forum, I believe they may need professional service beyond my electronics knowledge.
One issue I cannot resolve has to do with the temp sensor. It is a steady red LED. The documentation says:
TEMP (Red) - Steady indicates the dimmer is too hot and is preparing to shut down. Flashing indicates the dimmer has reduced levels or is shutting down in order to lower internal operating temperatures. (See FAN OPERATION and OVER TEMPERATURE.)
So, I have tried the following:
To adjust the temperature sensing of the DDS 88/9800( 86/9600 ) dimmers please see below;
IMPORTANT: BE SURE DIMMER PACK AT ROOM TEMPERATURE!!
1. Activate the calibration mode by holding down focus test switchs 4 and 8 ( 3 and 6 ) together for about 6 seconds. You will notice the fan runs at high speed , the line indicator LEDs begin to flash and the temp LED is on. NOTE: If the temp led is off no calibration is required.
2. Press focus test switch 2 ( 1 ) if calibration is low or focus test switch 3 ( 2 ) if high. You will notice the temp load indicator LED should go off indicating proper calibration.
3. Press focus test switch 4 and 8 ( 3 and 6 ) together to exit the temperature calibration mode.
There is still a constant red light. The fan stays on at a very low speed. No line indicators LEDs flash.
What does #2 above mean in reference to calibration being low or high?
Just one more thing for now: I found a guide on this forum that shows how to do a hard reset. What should this actually result in?
Thank you for any help.
