Mounting

The DS dimmer packs are designed to be mounted in a standard 19" EIA rack. The packs are provided with two

mounting flanges or ears, which are designed for securing the pack to the front rack mounting rails. The pack may

also be operated as is on top of a sturdy table or shelf.

An optional rear support kit is available and should be used in portable, or rough handling rack mount applications.

The NSI DS dimmers depend on forced air cooling, therefore the following installation rules apply:

1. The rack enclosure shall maintain a 2 inch minimum clearance on the entire right side of the dimmer

rack enclosure for air exhaust. The rack enclosure must not be sealed, and must maintain an air

exhaust clearance area of at least 15 square inches per installed pack for air to flow back to the

ambient room.

2. If the optional rear support kit is used, the right rear support bracket must be cropped to a length

that does not block any of the air exhaust vent on the right side of the rack, once the pack is installed.

Support bracket length can vary depending on cabinet construction and manufacturer, therefore the

bracket should be cropped upon installation.

3. The intake manifold on the front of the dimmer pack cannot not be blocked for any reason.

4. The thermal operation of the dimmer pack will depend on its conditions of installation. Ambient

room temperature must never exceed 104 degrees F or 40 degrees C.

WARNING: If any of the cooling rules above are violated, the packs could suffer permanent damage not

covered under warranty.

Input Power Wiring

WARNING: Because DS packs operate at potentially lethal voltages, installation wiring should be done by

qualified personnel only!

WARNING: Do no connect chassis Ground to Neutral, or operate this equipment without a chassis ground,

otherwise the user could be exposed to potentially lethal voltages.

The DS dimmer pack must be fed with one of the electrical services listed below. The service should be protected by

a suitable circuit breaker. Wiring should be selected, sized and installed in accordance with local electrical codes as

should all aspects of the installation. All wire must be copper, and be rated for 90oC sized for 75oC ampacity.

For convenience, suggested portable cord sizes are shown in parenthesis. They are sized for the full capacity of the

dimmer pack and for the 60oC-rated plug that is likely to be installed on the other end.

Feeder re-wiring procedure for 12 channel single phase units:

1. All power feeders should be turned off and disconnected.

2. Remove the dimmer pack cover by removing the screws around the edge.

3. Using a flat blade screwdriver, disconnect the 18 AWG red control module power wire from the B phase power

feed terminal block, and move it to the C phase power feed terminal block along with the #18 AWG blue control

module power wire, and terminate using set screw torqued to 35 inch-lbs.

4. Using a flat blade screwdriver, disconnect the red dimmer module feeder wire pairs with the single and double

red tie-wraps (dimmers 5&6 and 7&8) by unscrewing the set screws in the B phase power feed terminal block,

and sliding the wires out of the back slot.

5. Move the red dimmer module feeder wire pair with the single red tie-wrap to the A phase power feed terminal

block, slide in the wires deep in the terminal block mounting holes so no wire is exposed past the walls of the

block, and terminate using set screw torqued to 35 inch-lbs.

6. Move the red dimmer module feeder wire pair with the double red tie-wraps to the C phase power feed terminal

block, slide in the wires deep in the terminal block mounting holes so no wire is exposed past the walls of the

block, and terminate using set screw torqued to 35 inch-lbs.

7. Cross check:

•All black tie-wrapped and single red tie-wrapped feed wire pairs, and the Phase A black 18AWG control module

power wire should be fed by the Phase A feeder block

•All blue tie-wrapped and double red tie-wrapped feed wire pairs, phase B red 18AWG control module power wire,

and the phase C blue 18AWG control module should be fed by Phase C feeder block.

•Phase B feeder block should be empty.

•All load connections should be not exposed, and terminated tightly to 35 inch-lbs.

Output Power Wiring

DS packs are available in a variety of configurations. NEMA 5-15 or 5-20 receptacle, or Stage Pin receptacle

models feature one output receptacle per dimming circuit, while the hard-wired packs feature terminal blocks and a

rear panel with knock-outs.

The lighting load connected to the dimming circuit should be rated for 115/120V and should not exceed the rating of

the dimmer. The ampacity of the dimmer can be seen in the window near the yellow led load indicator on the front

panel, 10 = 10 Amps, 20 = 20 Amps.

The dimmer is capable of driving incandescent , Advance MARK X fluorescent ballasted, or inductive transformer

loads. The load on the dimmer must include the load of the lamp plus the load of the ballast or transformer; and each

ballast or transformer must be individually fused. Transformers should be over-rated by at an additional 70% of their

rated load when operating on an SCR dimming circuit. Other loads may be unsuitable to operation by a SCR based

switching devices, and may operate in an erratic and/or unpredictable fashion. Contact the manufacturer of the load

equipment for details of their power specification.

The proper wiring of a Stage Pin receptacle is not always evident. The center pin is the green grounding conductor;

the pin nearest the ground pin is the white grounded (neutral) conductor; and the remaining pin is the ungrounded

(hot) conductor.

1. Turn Lights On…Now!

2. Setup

3. Softpatch

4. Analog Submasters

5. Presets

6. Dimmer Feedback

7. Control Module Jumper Settings

8. Contact NSI

__________________

Section 1 1. Make sure all three red led power indicators on the front are lit.

2. Make sure lighting loads are plugged into back of pack .

To turn lights on now: 3. Flip all circuit breakers up to "ON" position.

4. Press test switch oval under each circuit breaker.

1.1 Setting the Test Switch Bump or Latch action and level:

If the test switches have been configured as " latch" action, the lights will stay on at the first press of the test switch,

but if the test switches have been configured as "bump" action, they will only stay on as long as they are pressed.

To change the test switch action, and the test switch intensity, press [CLEAR] until the following menu is displayed:

NSI DSxx xPHASE Note: the 'x's could indicate a variety of settings

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 xPHASE

[SETUP] [MORE]

Press the soft switch under [SETUP]. Then press [MORE] 2 times. The screen should now display :

SET TEST SWITCH

[ACTION] [MORE]

Select [ACTION]. Two choices will be displayed [LATCH] and [BUMP]. Press the test function you prefer.

This selection will stay in permanent EEPROM memory. Upon selection, another choice will appear:

SET TEST LEVEL = 25%

[CHANGE] [MORE]

If you wish to change the output intensity of the bump switches, select [CHANGE]. This change is in volatile

memory, or RAM , so it will go back to 25% when the power to the pack turned off. The level setting will not take

effect, however, until the test switch is activated again.

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 xPHASE Note: the 'x's could indicate a variety of settings

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 xPHASE

[SETUP] [MORE]

Press the softswitch under [SETUP]. The first setup menu will appear:

SET # OF DIMMERS

[8/12] [MORE]

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] [12]

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 xPHASE Note: the 'x's could indicate a variety of settings

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.

STATUS=xxx [MORE]

Press the key sequence [MORE], [MORE], [SETUP], [MORE] [MORE]. The following menu will be displayed:

SET TEST SWITCH

[ACTION] [MORE]

Select [ACTION]. The following menu will be displayed:

SWITCH ACTION =

[LATCH] [BUMP]

If you select [LATCH], the dimmer channel will toggle between the bump level and off each time the test switch

under the circuit breaker is pressed. If you select [BUMP], the dimmer channel will turn on only while the test switch

is being pressed. After selecting the test switch action, the following menu will appear:

SET TEST LVL = 25%

[CHANGE] [MORE]

If you wish to change the test switch bump level, press change, then enter the 'on' control level you wish the

channels to bump or latch to. Note: the bump level selection is only stored in ram, so it will default back to 25%

when the pack is powered off.

2.4 Analog Input Defaults Selection:

The 0-10VDC analog inputs on this DS dimmer pack do not have to be just 0-10VDC control inputs for single

channel dimmer control. The analog inputs can also operate as overlapping submaster scenes with time fade

damping, or trigger inputs to linked presets that can operate in a chase pattern on one of the analog submasters. To

program these functions, refer to the Analog Submaster section of this manual. Enabling [DEFAULTS] in this

menu will erase all the submaster scenes and their fade times, and re-program all inputs to a 1 to 1 patch with

0 time fade damping. ( analog input 1 = channel 1, analog input 2 = channel 2, … analog input 12 = channel 12 ).

From the main menu:

2.7 Set Line Regulation

This menu enables or disables the line regulation feature of the dimmer pack. Line regulation is a feedback system

that monitors the incoming line voltage, and attempts to compensate for surges or sags in the feeder voltage by

inversely dimming the output up or down, thereby maintaining a constant output voltage to the lamp. This feature

operates best when the incoming feed power voltage is about 125VAC. The dimmer pack then has the head room to

keep the lamps operating at their maximum voltage, even if the feed voltage sags or surges a few volts. The DS

dimmer pack should never be fed with line voltage above 130VAC, however, especially while operating in the non-

regulated mode.

Line regulation can be susceptible to operational problems on very soft or very unstable power feeds. For this

reason, the user has the ability to turn off line regulation from this menu. Although this may alleviate most power

feed interaction problems, it can not correct for poor installations with extremely soft and /or noisy feeders and

neutrals, from which can cause false triggering can occur due to false feeder zero cross information.

To change the line regulation setting, from the main menu:

NSI DSxx xPHASE

STATUS=xxx [MORE]

press the key sequence [MORE], [MORE], [SETUP], [MORE], [MORE], [MORE], [MORE], [MORE],

[MORE], [MORE]. The following menu will be displayed:

SET LINE REG = ON

[OFF] [MORE]

The active line regulation setting will be displayed to the right of the equal sign, with the alternate option displayed

for the left soft key function (F1). To toggle the line regulation operation, press the (F1) function key. The new

setting will be stored in permanent EEPROM memory, and will automatically load on power-up.
