:SETUP AND CONNECTION
A// Mechanical Installation
Remove all packing material from the unit. Make certain that all holes
are free of obstruction on all sides of the unit. Replace all packing
material in the carton and store it for reuse. The backplane mounting
holes are spaced 16" on center for convenient wall mounting. Do not
block any vent holes. Make certain that the vent holes all have at
least 6 inches of free air around them. It is essential that this unit
have adequate cooling for safe, reliable performance. Maximum air
temperature must not exceed 40 degrees Centigrade (105 degrees
Fahrenheit).
B// Electrical Installation
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 formula amps = watts ÷ volts. For example, if
twenty-four 1200-watt, 120 volt lighting units are connected to the
dimmer, it would require 28,800÷120, or 240 amps total power when
all channels are at full. This is available from a three phase 4 wire
80 amp or a single phase 3 wire 120 amp service. Usually this much
power is not required and a 40 - 60 amp service may be used with lower
power loads plugged in.
The Dimmermaster accepts either three phase or single phase power
input and is factory configured for three phase. Line to neutral
voltage is always 120 volts. Line 1 to Line 2 voltage is 208 volts in
three phase service and 240 volts in single phase service. It is 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
the lamps. A double check of voltages before applying power can guard
against such disaster. The power input connector is a terminal block.
Each leg of the power feed connects to one terminal on the dimmer
pack. These are marked "L1", "L2", and "L3". The neutral connection is
made on the neutral bar, just to the right of the power block. The
ground connection is made on the ground terminal, just below the
04\\
power block. The pack has circuit breakers to protect each dimmer
channel, but the primary circuit protection and disconnect is to be
provided by the user. When single phase service is used switch S2,
located near the center of the plug-in circuit board, must be moved
from the 3 phase position to the 1 phase position. The power input
terminal marked "L3" is not used. The two blue wires wrapped with red
tape must be moved to the terminalmarked "L1" and the two wrapped
with black tape to "L2". The tiny blue wire stays in terminal "L3".

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 dimmer pack consists of 12 or 24 dimming channels.
The Dimmermaster will dim any load from 1 watt through 1200 watts
or 1 watt through 2400 watts at 120 volts for a 2412 and a 1224
respectively. The load may be incandescent, inductive, or resistive.
This includes conventional incandescent, quartz incandescent,
rain-lights, pin beams, and similar lamp loads. This does not include
fluorescent or neon lamps. Fluorescent lamps with dimmable ball asts
may be dimmed by other means; consult the factory for help.
There is one lug for each output and a neutral bar for all neutrals.
Lugs are numbered according to their circuits. There should be a
separate neutral returning from each load circuit.
E// Control Connections
The Dimmermaster 1224 and 2412 can take either of two control
protocols: USITT DMX-512 or 0 to +10VDC analog. All control
connections are made on connectors or terminals inside the pack.
Positions are labeled as to function. The optional power supply
sends power to passive controllers (those that do not plug into
the wall).

When the temperature of the heatsink exceeds 75 degrees Celsius,
the control is cut off. This prevents overheating. When the heatsink
cools, the loads begin to work again. If this happens, the air
circulation around the dimmer should be improved. Check that the
internal fan has not failed.

F// Channel Selection and Testing
The thumbwheel switch inside the pack is the channel selection switch.
The number shown is the starting dimmer. Valid starting dimmer
numbers range from 1 to 489. The starting dimmer number determines
the setting for the entire pack of twenty-four dimmers. If, for example,
the starting dimmer number is 25, the pack reads control signals for
channels 25 through 48. When the first digit of the thumbwheel
switch reads "6", the pack is in load testing mode. The second and
third digits show the dimmer being tested, from 1 to 24. The load test
forces the output of the dimmer to full. This is helpful for focusing
and troubleshooting. (e.g. Which channel is that? Is the lamp burnt
out?) A setting of "600" drives all lamps at 20%.
G// Indicators
The status indicator LED is used to check the Dimmermaster for proper
control and power connections. The LED shines green when it is
receiving power and a valid DMX signal, and red when it is receiving
power but a bad signal. The LED shines red when it is receiving an
analog signal only. No light at all means that it is not receiving power.
H// Internal Switches
A 9 position internal DIP switch sets various options. These include
DMX line termination and nondim operation. DIP switch functions are
printed on the circuit board. To terminate the DMX line (this is the
last dimmer in the DMX string), turn on DIP switch number 1 (which
terminates DMX pins 2 and 3) and 9 (which terminates
DMX pins 4 and 5). All outputs at or above a specified number may be
set to nondim. When set to nondim, an output is full when fed with
50% (DMX level 128, analog +5V). or higher. Below this threshold,
the output is off. The first nondim output is set using binary coding
on the DIP switch. For example, if outputs 7 and above are to be
nondim, switches 2, 3, and 4 would be set to the on position, since
these correspond to nondim 1, nondim 2, and nondim 4. 1+2+4=7,
so outputs 7 and above will be nondim.
