2408 CD I CR DIMMER SYSTEM
Software Revision 2.0, Version C
2408 CD / CR DIMMER SYSTEM
INSTALLATION AND OPERATION GUIDE
INTRODUCTION
The NSI 2408 dimmer represents a key part of a state of the art, total lighting control system. Combined
with either NSI remote control panels and / or an NSI memory control console, a totally integrated
system is achieved.
The 2408 provides eight channels of 2400 watts each. This dimmer is designed to be permanently
installed for control of house or stage lighting in schools, churches, theaters, buildings, etc. Several
remote control panels such as the NSI 400CP may be mounted at doorways, or other locations at which
dimmer control is desired. For entertainment lighting; an NSI memory control console or other suitable
console may be added to the system for special lighting effects. Several 2408 dimmer packs may be
combined for more channels or circuits of lighting.

Page 3: Input Wiring
2408 CD / CR DIMMER SYSTEM Software Revision 2-0, Version C INPUT WIRING The 2408 CD/CR must be provided with an 80 amp, 120/240 or l20/208Y VAC, three wire electrical service. This service must include two live wires not exceeding 150 volts to ground and one neutral wire. - Page 4 LOAD WIRING LOAD WIRING The 2408 CD/CR can provide eight tungsten or resistive branch lighting circuits of 120V AC at 20 amps each. If the lighting loads are expected to operate continuously at full power for three hours or more, then the load must not exceed 16 amps in accordance with electrical codes.

Page 5: Control Wiring
LOAD WIRING IS COMPLETE BEFORE ENERGIZING ELECTRICAL SERVICE TO DIMMER. CONTROL WIRING Control wiring to the 2408CD should be Class 2 wiring. All control wiring must stay below the barrier separating the control wiring compartment from the load wiring. All control wiring must exit out of either of the 1/2"-3/4"... - Page 6 Microplex multiplex control wiring. Microplex is the control protocol used on all NSI lighting console. This system uses a shielded wire to transmit up to 128 channels of dimmer control. Microplex should not be used simultaneously with DMX-512. For short distances (50 feet) a standard microphone cable is used to carry both the control signal and the DC power source for NSI control consoles.

2408 CD / CR DIMMER SYSTEM Software Revision 2.0, Version C JUMPER SETTINGS NON-VOLATILE MEMORY The version C control card now contains an EEPROM device to store lighting levels for automatic full restoration after a power fail. When the installer enables this feature, the dimmer will save the current lighting levels in non- volatile memory 10 minutes after there has been a change in lighting levels. -
Page 8: Switch Settings
SWITCH SETTINGS SWITCH SETTINGS When using any of the multiplex control systems the dip switches on the 2408 CD/CR must be set to assign the desired dimmer channels. The switches control the dimmer channels in groups of four .The dip switch on the left dimmer firing card controls circuit channels 1-4 while the dip switch on the right card controls circuit channels 5-8 of the pack. -
