Section 2 SETUP
The DS dimmer pack will be ship pre-configured with factory default settings, however, it may be necessary to
change some of those settings in the field based on installation requirements or service conditions. The following
section steps through the various control setup options.

2.1 Number of dimmers selection:

Press [CLEAR] until the following main menu is displayed:
NSI DSxx
STATUS=xxx [MORE]
Now press the switch under [MORE] twice. This switch is a soft switch, that is, the function of the switch is defined
by the bracketed text in the LCD window above. If you are lost or make a mis-entry, just hit [CLEAR]. The menu
will back up one position or one menu each time [CLEAR] is pressed. The LCD should now display:
NSI DSxx
[SETUP]
Press the softswitch under [SETUP]. The first setup menu will appear:
SET # OF DIMMERS
[8/12]
The control module can operate either a 8 channel or 12 channel dimmer pack, but it needs to be told how many
dimmers are in the pack. If you wish to change the number of dimmers, press the [8/12] soft switch. The next
selection you make will be permanently stored in the non-volatile EEPROM configuration chip. The LCD will
display:
# OF DIMMERS =
[8]
Select the number of dimmers that are installed in the pack, or press [CLEAR] to go back to the previous menu. If
you change settings, the changes will not be reflected until the pack is powered off, and then back on. A number
selection will return to the display to the main menu.

2.2 Phase power selection:

From the main menu:
NSI DSxx
STATUS=xxx [MORE]
Press the key sequence [MORE], [MORE], [SETUP], [MORE]. The following menu will be displayed:
SET PHASE POWER
[1/3 PHASE] [MORE]
An 8 channel dimmer pack will always be setup for 1 phase. A 12 channel dimmer pack may operate as either a
single phase or 3 phase unit. Single phase 12 channel units need to be internally configured for single phase power,
so for single phase 12 channel units, refer to Input Power Wiring section and Re-wiring Procedure. If the wrong
phase power type is selected from the LCD menu no damage will occur to the dimmer pack, but it will not operate
correctly and may operate as a non-dim or with odd dimming curves. Like with the number of dimmers selection,
phase control selection is stored in non-volatile EEPROM and configures on power-up, therefore the pack must be
powered off and back on to have phase changes implemented.
