RECEIVING YOUR EQUIPMENT
As soon as you have received your equipment, open the
boxes and examine the contents. If any damage is noted,
contact the carrier immediately to file a claim for damages. You can be sure that when the equipment left the
factory it was in good condition and properly packed. If
you find the equipment to be in accordance with your
order and the packing slip, and also in good physical
condition you may read on to the section covering SETUP
AND CONNECTION. If, for some reason, the equipment in
the carton does not agree with your order or the packing slip, contact the factory immediately and we will be
happy to help you.

:SETUP AND CONNECTION
A// Mechanical Installation
Remove all packing material from the carton and from the unit.
Make certain that all cooling fins and holes are free of obstruction
on all sides of the unit.
For portable use, set the Dimmermaster on a smooth, cool surface,
preferably in an area which remains fairly cool. Maximum air
temperature must not exceed 40 degrees Centigrade (105 degrees
Fahrenheit). Make certain that the vent holes all have at least 6
inches of free air around them. Up to 4 packs may be stacked
vertically. Do not remove the feet when stacking. Do not block any
vent holes. It is essential that this unit have adequate cooling for
safe, reliable performance.
B// Rack Mounting
For larger systems, the Dimmermaster can be rack mounted in a
standard EIA 19-inch equipment rack. Rack ears may be easily attached
to the heat sink and feet must be removed. The Dimmermaster occupies
3.5 inches of space in the rack. To insure proper operation, the
rack enclosure must be ventilated. Air should be exhausted from
the top of the cabinet at a minimum of 200 cubic feet per minute.
Top and bottom panels should be removed for improved ventilation.
The tiny blue wire stays in terminal "L3".
C// Electrical Installation
The Dimmermaster 824D consists of eight dimming channels. Each of
these channels may be operated from a voltage of 100 to 240 volts
referenced to the neutral terminal. Frequency of operation is 50 or
60 Hertz. The 824D will adjust automatically to the proper voltage
and frequency. If the dimmer is operated at 240V then the lamps
MUST also be rated at 240V. Because the Dimmermaster controls
the flow of electricity to the lighting instruments, the dimmer must
be supplied with an amount of current equal to the combined total
current of the lamps it controls. To calculate this current, use the
04\\
formula amps=watts/volts. For example, if eight 1200-watt, 120 volt
lighting units are connected to the dimmer, it would require 9600/120,
or 80 amps.
The power input connectors is a terminal block. This model has circuit
breakers to protect each dimmer channel. The primary circuit
protection and disconnect is to be provided by the user. Number 4
AWG wire is recommended for power feed. See Power Input Connection
Chart.

OWNER’S MANUAL
It is also very important that the input voltages be checked with a
meter to insure that they are correct. A mistake can place
208 to 240 volts across a 120 volt lamp. The breakers will protect
the unit but may not save your lamps. A double check of voltages
before applying power can guard against such disaster.
C// Grounding
The term GROUNDING refers to a separate wire with green insulation
which is connected from the equipment case to earth ground
(often through a properly grounded conduit system). This is not the
same as the neutral or common and must not be confused with them.
The neutral is a separate, load-carrying circuit conductor. The ground
conductor should not normally carry current. When the
Dimmermaster is connected to its power source by conduit, the ground
connection can be made via the conduit itself. If flexible conduit is
used, a separate bonding conductor will usually be required.
Always check your local codes for hook-up before operating this
equipment. It is recommended that power connections to the
Dimmermaster be made by a qualified electrician.
D// Load Connections
The Dimmermaster 824 will dim any load from 1 watt through
2400 watts. The load may be incandescent, inductive, or resistive.
This includes conventional incandescent, quartz incandescent,
rain-lights, pin beams, and similar lamp loads. The output connector
can be U-ground, stage pin, or terminal block.
OWNER’S MANUAL
Multiplex control input connections are made through the five pin
male XLR on the back of the unit. Analog control input connections
are made through the DB-15 male connector inside the unit. For
analog use, the Dimmermaster requires 8 control inputs, referenced
to a signal common. This common is isolated from the neutral and
chassis. Signal voltage is 0 to +10 volts pure DC. Maximum output
is obtained at +10 volts.
XLR AMX OR DMX DB-15
PIN 1 Common PIN 1 Channel 1 PIN 6 Channel 6
2 -Clock (Data) 2 Channel 2 7 Channel 7
3 +Clock (Data) 3 Channel 3 8 Channel 8
4 Analog (AMX) 4 Channel 4 15 Common
5 Overtemp 5 Channel 5 (9-14 not used)
F// Indicators
The status indicator LED is used to check the Dimmermaster for
proper control and power connections. It shines green when it is
receiving power and is being addressed properly by a multiplex
controller, and both red and green (amber) when it is receiving
power but not a proper multiplex signal or is incorrectly set up.
It also shines both red and green when it is set up for an analog
signal. No light at all means that it is not receiving power.
If your unit has receptacles installed, merely plug the load into the
outlet which corresponds to the circuit you desire to use.
For terminal-block-only units, there is one lug for each output and
one for all neutrals. There must be a separate neutral returning
from each load circuit. DO NOT COMMON NEUTRALS BETWEEN
DIMMER AND LOAD. Lugs are numbered according to their circuits.
E// Control Connections
05\\
The DM824D can take any of three control protocols:
USITT AMX-192, DMX-512, or 0 to +10VDC analog.
The multiplex control protocol is factory set as per the customer's
requirements, but it can be changed through jumpers on the circuit
board. See Control Input Connections Chart for jumper locations.
