and relay packs are the heart of any stage lighting system.
They translate coded signals generated by controllers into power levels
required to drive high power lamps to desired intensities.
The NSI NR 3000 satellite relay pack is fully user programmable
allowing assignment of four of a possible sixty-four control channels.
Micro-plex. a new technology developed by NSI for the stage lighting
market. is the electrical marriage of micro-processor technology with
digitally controlled multiplexing. This technology allows all NSI lighting
components to be connected with standard 3-pin microphone cables or even
audio snakes. System expansion is further simplified through the ability
to daisy chain additional relay packs to an existing system. This
application of Micro-plex technology makes system set up and operation easy
and convenient.
Our philosophy at NSI is to utilize only the highest quality
components. Problems that often plague relays such as flickering lights,
buzzing in audio equipment and triac failure are eliminated in NSI
products. In place of unreliable triacs, NSI only uses professional grade
dual
SCR's.
You can be confident
and reliability standards
your NSI relay packs feature the best performance
available.

AC OUTPUT -RECEPTACLES
Dual standard AC outlet receptaclesare provided for each channelof the NR
3000.
These receptaclesprovide power to the lamps in your lighting
system. Digitally coded signals received from your NSI controller are
translated into power. Each dual receptacle corresponds to a single
channel with the maximum power capabilities described in the specifications
section of this manual. Under no circumstances should maximum recommended
power capabilities be exceeded. To do so may be hazardous and will void
your warranty. Most lamps, fixtures, effects motors and also rain lights
may be connected to these outlets. Do not connect any other electrical
appliances or equipment to the relay packs.
MICRO-PLEX
INPUTS
Both the male and female Micro-Plex connectors may be used for input
signals. Micro-Plex technology allows your system to be connected using
standard microphone cables or even audio snakes. Digitally coded signals
may be received from your NSI controller or another relay pack. The
Micro-Plex system also provides D.C. phantom power to your control unit
eliminatingthe need for
AC power cords on any NSI controller.
Up to
sixty-four individual control channels plus phantom power to your
controller may be transmitted through a single microphone cable.
MICRO-PLEX EXPANSION
The male
and female Micro-Plexconnectorsare wired in parallel allowing
either one to be used for input or output of control signals. When used as
an output, the Micro-Plex connectors will provide control signals to
another relay pack. This is called daisy chaining and makes expansion of
your system easy. Up to sixty-four individual control signals may be sent
through NSI relay packs via a standard microphone cable.
PROGRAMMING
Each NSI relay pack is fully user programmable to receive any of
sixty-four possible control signals. Control signals may be assigned in
increments of four by programming the relay packs to receive them. To
accomplish this simply position the program select switches as described in
the following chart:

yellow LED's (Light Emitting Diodes) for each channel indicate
when relay is receiving control signals. This feature is an excellent
trouble shooting tool in identifying possible problems with signal
transmissions or defective lamps and fixtures.
IMPORTANT:
All NSI relay packs are shipped from the
factory programmed for channels 1-4.
Units must be
reprogrammed (see chart above) before being capable of
receiving any other channels.
AC POWER CABLE
This is the main power cord for your relay pack which ultimately carries
all of the AC power consumed by lights connected to the relay. It must be
connected to a power source capable of supplying the total power drawn by
the lights (see specification section of this manual for details on maximum
power capability).
WARNING: Do not remove grounding prong of AC plug. To
do so may cause exposure to potentially lethal voltage
levels and will void the warranty on this product.
POWER ON INDICATOR
This green LED (Light Emitting Diode) will light whenever the dimer pack is
receiving AC power and functioning properly.
CIRCUIT PROTECTION
The NR 3000 is equipped with safety circuit interruption devices to protect
the units from becoming overloaded. The NR 3000 utilizes a resetable
external circuit breaker as well as internal fusing.
MOUNTING
NSI NR 3000 relay packs are designed to be mounted vertically. Each relay
pack is provided with two mounting flanges or ears designed for securing to
the center of truss bars. Most truss bars are already properly drilled to
accept mounting of relays, however in some cases you may need to drill
holes in your truss bar to accommodate your relay pack. When doing this
insure hole spacing is accurate before attempting to drill.
OPERATIONAL HINTS
1) Always place your relay packs as close as possible to the lights they
power. This will reduce the number of extension cords required to hook up
your system.
2) Use a power outlet located as close as possible to an electrical
service panel (fusebox). It is best if the power outlet is on a separate
circuit breaker or fuse from your audio system.
3) Insure that the rating of the breaker or fuse for the chosen outlet is
adequate. The required rating (in amps) of the breaker or fuse may be
calculated with the following formula:
I
=
P
E
Where I
P
and E
=
=
=
the current (in amps)
the power (in watts)
the voltage (in volts)
With a standard 120 VAC electrical system 100 watts = 5/6 of an amp.
A safe and easy assumption is to say 100 watts = 1 amp. For example;
if
you are using four 500 watt lamps (2000 watts total), you should have at
least a 20 amp electrical service.
4)
Always use quality 14 gauge (or heavier) grounded extension cords.
5) Do not place AC power cables or extension cords for lighting near
sensitive audio cables (guitar cords, mic cables, audio snakes, etc.).
6) Avoid blocking the ventilation holes on the sides of your relay pack.
It is very important your unit has this ventilation to avoid possible
damage which may void the warranty.
