Powerlight 612 version1.03
Designed and Manufactured in Ital b SGM Elettronica srl
Printed in June, 2001 • Rel. 1.03
Introduction
Power Light P612 is a new digital dimmer entirely designed and developed by SGM's Research &
Development Department. Careful study of its functions, selection of innovative material and on-
going technical updates have resulted in the manufacture of a truly unique product, able to satisfy
the requirements of applications in the live sector and well as fixed installations. Particular care
has been taken with the design of the cooling system, which also enabled the unit's dimensions
to be kept down to 2 rack units. This enables the dimmers to be tacked without leaving space for
air circulation between them, thus considerably reducing the space taken up in the event of
installation in racks.
Use of the unit's fans does not in any way jeopardise the possibility of using the dimmer in
locations in which noise has to be kept to a minimum, as Power Light P612 uses very low-noise
fans which are silent even when operating; their rotation speed is also electronically controlled
and directly proportional to the dimmer's internal temperature.
The fact that it's able to be used without necessarily being controlled by a lighting control desk
makes Power Light P612 extremely versatile and enables it to be used in any sector.
Powerful software keeps the various sections of the dimmer under constant control, intervening
with special protection procedure in the event of faulty operation, and indicating any irregularities.
The Power Light P612 has been built in compliance with current CE norms.page 6 P612D

1.3.5 DMX termination construction
The termination avoids the possibilit of the DMX 512 signal being sent back along the cable
once it reaches the end: under certain conditions and with certain lengths, this could cause it
to over-ride the original signal and cancel it.
The termination is made b soldering a 120 1/4 W resistor across pins 2 and 3 of the 5-pole
male XLR connector (see diagram).
1.3.6 Connection RS-232
Good quality screened RG 58 50 co-ax cables must be used for connections
to avoid faulty equipment operation. Connectors used are always of the 5-pole XLR type. Refer to the
diagram for wiring.

2 - Menu descriptions
2.1 Soft Patch
n this Menu, it's possible to assign the POWER L GHT's physical channels (CHN) to the digital
channels available (ADDR). This creates a correspondence between the Dimmer output channel
and the channel that has to be controlled.
There are 512 channels available for use, i.e., those provided for by DMX standard, and they don't
necessarily have to be in succession.
For access to the
Soft Patch function, proceed as follows:
1. Select SOFTPATCH in the main menu;
2. Press Enter to confirm the choice;
3. Move the square brackets to the CHN field and select the channel to be assigned;
4. Move the square brackets to the ADDR field to assign the digital channel to the channel that
has just been selected;
5. Repeat from point 3 to assign the other channels.
6. Press Esc to return to the main menu - the selected data are automatically updated.
2.2 Set Chn Mode (Channel Mode)
n this Menu, it's possible to choose the operating mode for each individual channel. t is in fact
possible to control the Power Light's channels independently or via a lighting control desk.
There are three operating modes available:
- FIX. The output of channels set in this mode isn't controlled by a lighting control desk and
remains fixed on a value which can be set later.
- OFF. The output of channels set in this operating mode stays off and cannot be controlled by a
lighting control desk
- EXT. (EXTERNAL) Output channels set in this mode can only be controlled by a lighting control
desk.
The standard factor setting is with all the channels in EXT.
For access to the Set Channel Mode function, proceed as follows:
1. Select the Channel Mode menu from the main menu;
2. Press Enter to confirm the choice;
3. Move the square brackets to the CHN field and select the channel to which the operating mode

Powerlight 612 version1.03
has to be assigned;
4. Now move the square brackets to the MOD field to assign one of the three operating modes
available;
5. Repeat from point 3 to set the other channels.
6. Press Esc to return to the main menu:
2.3 Set Chn Level (Channel Level)
n this Menu it's possible to set the level of each individual channel configured in F X mode in the
previous menu.
To access the
Set Channel Level function , proceed as follows:
1. Select the Set Channel Level menu from the main menu;
2. Press Enter to confirm the choice;
3. Move the square brackets to the CHN field and select the channel the output level has to be set
on;
4. Now move the square brackets to the LEV field to assign the output level. This is expressed as
a decimal value of between 000 and 255;
5. Repeat from point 3 to set the other channels.
6. Press Esc to return to the main menu: the selected data are automatically updated.
2.4 Set Pre Heat
n this Menu, it's possible to set the pre heat (warm-up) level of each individual channel.
ncandescent lamps' behaviour varies according to the power voltage they are supplied.
When they are cold, before voltage is applied, the filament has a very low resistance, so at the
moment in which the voltage is applied, a very high current will pass through the lamp.
This explains why frequent voltage changes can have a negative effect on lamp life: it's therefore
indispensable to set warm-up level.
This enables to set the minimum current which must pass through in the lamp when it is not lit,
in order for the absorption of current to be reduced and lamp life increased.
This is expressed as a percentage of between 0% and 9.9% and is usually left at zero for
inductive
loads (neon, par 36), whereas for resistive loads it varies according to the type of lamp used.
For a good warm-up, it's sufficient to increase the level until the filament becomes just visible.
Standard factory warm-up setting is 4%

This Menu runs an autotest routine which enables irregularities to be found in some crucial points
of the Power Light. n fact. the following parameters are checked:
- correct operation of both fans;
- the voltage on the three input phases;
- any excess voltage on input,
- any overloading on the power output;
- any short-circuitng on the power output;
- the presence (or not) of DMX signal on input;
- the presence (or not) of RS-232 signal on input;
- the temperature on the cooling fins expressed in degrees Centigrade and Fahrenheit.
Run Autotest is only an executive menu - no parameters can be modified.

3 - Protections
Particular protections are provided to avoid any faulty operation seriously damaging the Power
Light. These protections are:
3.1 - OVER-HEATING PROTECTION: the maximum temperature allowed is 90ºC and is measured
on the cooling fin on the power section. f this temperature is exceeded, the output is disabled
until temperature returns within the foreseen limits. At 80°, an over-heating pre-alarm message is
given.
3.2 - OVERLOAD PROTECTION: the output is electronically limited to a maximum of 12 Amps
per channel no matter what load is applied
3.3 - PROTECTION AGAINST SHORT-CIRCUITING: should a short-circuit occur, the Power Light
immediately switches off the channel in question and then attempts to switch it on slowly after
approximately 8 sec.; if the short-circuit persists, Power Light switches the channel off again and
then attempts to switch it on.
3.4 - PROTECTION AGAIN INCORRECT CONNECTIONS: regarding the power supply circuit.
There are two protections: an electronic one which blocks the power supply and indicates the
phase in question on the display, and a fuse which blows to avoid overloading damaging the
unit's internal circuitry.
4 - Error messages
Error messages are indicated by the display giving a long flash. Should a message indicating an
irregularity appear, switch off the Power Light immediately, find the cause and eliminate it.
f there are several messages simultaneously, they appear one after another.
