Section 6
Dimmer Feedback
The DS dimmer has several mechanisms for dimmer feedback. The most readily available feedback is the LED's on
the front panel display.
The green LED above each circuit breaker fades up and down proportional to the corresponding dimmer level.
The 3 red phase power indicators show that proper power has been applied to the pack, and all 3 power
transformers are receiving line power.
The yellow overtemp indicator illuminates if a dimmer module temperature exceeds 80 degrees C, and it also
blinks momentarily when a valid luminet command has been received.
The green Microplex indicator flashes in a fast, steady fashion if a valid Microplex signal is being received.
The green DMX indicator flashes in a fast, steady fashion if a valid DMX-512 signal is being received.
The lower line of the main menu displays a status menu that indicates a number of error conditions, like power input
over or under voltage, over-temperature status, configuration memory errors, and thermistor connection errors. It is
normal for some of these error indications to display breifly during power up, but after a few seconds, STATUS
should display "OK" If any of these errors occur consistently or permanently, please refer to section 8.
If the thermistor connection is broken between the control module and the dimmer module, or in the dimmer module
itself, the following message will be displayed on the bottom line of the main menu:
"THERM 1&2" -- if the thermistor connection for dimmers 1 & 2 is broken.
"THERM 3&4" -- if the thermistor connection for dimmers 3 & 4 is broken.
"THERM 5&6" -- if the thermistor connection for dimmers 5 & 6 is broken.
"THERM 7&8" -- if the thermistor connection for dimmers 7 & 8 is broken.
"THERM 9&10" -- if the thermistor connection for dimmers 9 & 10 is broken.
"THERM 11&12" -- if the thermistor connection for dimmers 11 & 12 is broken.
Note: The dimmers in the affected dimmer module cannot turn on until the thermistor connection problem is
rectified. Refer to section 8 of the manual for assistance.
Individual dimmer status can also be monitored. From the main menu :
NSI DSxx
STATUS=xxx [MORE]
Press the [DIMMER] keypad. The following menu will be displayed:
DIMMER # = 01
TEMP= xxC [MORE]
Note the temperature reading in the bottom left corner of the LCD display. This is the operational temperature of the
dimmer module of the selected dimmer. The temperature display has a resolution of 1degress C. The operational
temperature range of the DS dimmer module is 0 to 85 degrees C. The dimmer module will go into an over-temp
warning condition at 85 degrees C, and will linearly dim to off by 90 degrees C.
Press [MORE] to display the following status screen:
DIM 01 = xx% DIMR
SOURCE=yyy[MORE]
This screen displays a variety of live functions of the dimmer. This screen not only displays the current control level
for the dimmer, but also indicates where the control source level has been derived. Highest takes precedence Control
sources can be:
NSI DS8/DS12 MODULAR DIGITAL DIMMING SYSTEM
Software Revision 1.1x, 8/24/99
