General features
The Displayer 250 graphic projector is a result of the cutting edge design policy which all SGM pro-
ducts have had in common for years and has been expressly built for projecting logos, information and
publicity.
Like every SGM product, it passed the firm’s long trail period and strict tests brilliantly before being
put on the market, ensuring high quality and reliability up to customary SGM standards. The unit’s
carefully studied lines and optimisation of the bodywork ensure functionality, as well as enabling easy
installation in any position and making light work of any necessary maintenance.
Built to current CE norms, Displayer is a stand-alone projector, i.e. one that can be used without any
remote control. It has a very low voltage 2-pin halogen lamp, definitely ideal for this type of fixture, as
it combines reliability over its long life (up to 300 hours) and astonishing luminous power with a ludi-
crously low price tag - definitely nowhere near that of the metal halide lamps mounted on other projec-
tors of the same type.
The special SGM-designed reflector concentrates the beam and the condenser lens in selected glass
with a high transmission factor undergoes special multi-layer anti-glare treatment to further accentuate
brightness and luminous power.
Focussing is very easy, fast and really precise, thanks to the Focus screw knob on the front of the
projector.
Displayer has 8 standard colours obtained with 38 mm. dichroic filters, which are easily replaceable,
so custom needs can be met. The carefully selected top quality filters ensure perfect colour uniformity.
The group which holds the logos comprises a single 8-position wheel. They are all easily replaced, so
the operator can install new images very quickly.

To position the projector, switch it on, set it in the required
position by turning it on the support bracket, then lock it in
place with the knobs on the bracket.
Focussing the Displayer is very easy, fast and really precise,
using the Focus screw knob on the front of the projector.
Focussing is precise for all the projected images, thanks to
the positioning on a single projection plane.
Attention: due to the different physical characteristics
of images reproduced on dichroic glass or metal
(thickness of the support), Displayer must be fitted
with just one of the two. If a combination of glass and
metal is used, focussing won’t be precise for both.
To position one image use the dip-switch “option” #3 to have little steps for the perfect positioning.

Access and Maintenance
Displayer has a very unusual system for access to the inside of the projector. Although being left han-
ging in the position it’s installed in, the projector can be opened in half length-wise, thus enabling
extremely easy access to the components inside to carry out any necessary work (cleaning, relamping
or maintenance work on any mechanical or electronic parts, etc.).
To open the projector, unscrew the 2 knobs on the front (see illustration), making certain that the lower
part doesn’t drop downwards when the unscrewing is finished.
The opening is automatically locked in the fully open position.
Attention: before opening the fixture after it has been used for a while, wait for at
least 10 minute (the ideal time is 30 minutes), as the lamp and reflector reach
temperatures able to cause serious burns if touched.
focus
After carrying out the necessary work, before pushing the lower part upwards (fig. 2) to close the
projector, release the locking lever by raising it (fig. 3). Tighten the 2 knobs one after another, making
absolutely certain that they are correctly hooked on to the lower part, to avoid it unexpectedly dropping
down again.
Relamping
Before replacing the lamp:
- make certain that replacement is actually necessary;
- disconnect the fixture from the mains supply;
- if the fixture was on, wait for the lamp and the internal mechanical parts to cool down
before opening (about 30 minutes are necessary).
Remove the burnt-out lamp. Make absolutely certain not to touch the lenses, reflector or the lamp itself
with your bare hands, as residue burns at this high temperature, blackening the parts and definitively
damaging the lamp. Fit the new lamp, mounting it carefully in its holder.
To ensure correct protection, it’s important that the lamp is perfectly fitted into the holder.
Every time the lamp is replaced, it’s advisable to always carry out a complete cleaning cycle.

Cleaning the projector
Clean optics - inside and out - are decisive for luminous output and this work must be carried out
periodically. The regularity with which cleaning is done depends above all on the surroundings in
which the fixture is used: in particular, damp, very smoky or dusty surroundings cause dirt to build up
on the fixture’s optics. Always clean with a soft cloth and normal products for cleaning glass, or
methylated spirits, always drying the parts carefully. Clean the outside of the lens at least every 15/20
days and the inside optics group at least every 40/60 days (condenser lenses, reflector).
Replacing images and logos
After having disconnected the projector from the main power
supply, open it.
If the fixture was in use, wait for the lamp and mechanical
parts to cool (approximately 30 minutes are necessary).
Using a small screwdriver, remove the spring (C), replace
the gobo (B), then replace the spring, taking care to fit it per-
fectly on the special goboholder ring (A). Close the projector
correctly again.
Replacing colours
After having disconnected the projector from the mains power, open
it.
If the fixture was in use, wait for the lamp and mechanical parts to
cool (approximately 30 minutes are necessary). The colorwheel is
made up of two parts, between which the colour filters are fitted into
place.
To replace them: using your fingers, very delicately open the two
locking disks in the position corresponding to the dichroic filter to be
replaced, remove the filter and fit the new one. Close the wheel and
the projector correctly again.
Periodical checks
To ensure that the fixture is always in perfect running order, it’s advisable to carry out a periodic check
every 700 running hours. Electrical and mechanical parts must be checked by expert technical staff.

Displayer 250 functions
The Displayer 250 was designed and built for projecting logos and publicity images. It was therefore
intended for use in every possible situation.
Its functions are divided into two main groups: static and dynamic.
Static use is when the Displayer projects a single image, e.g. an arrow indicating an exit.
Dynamic use is when the projector uses all its positions for images (8 all together), projecting them
one at a time at intervals chosen by the operator. One example is an installation in a sports shop, in
which the logos of the key brands sold are projected.
In the event of a particular installation requiring it, Displayer can carry out “animation” work in both
static and dynamic modes.
In fact, a function called “dimmer sweep” can
be used which carries out a crossfade accor-
ding to the illustration alongside, where the
time (t) is chosen from those available.
It’s also possible to use Displayer’s colors
thanks to the “rainbow” function, during
which the colorwheel rotates continuously.
The last effect available is a 4-sided prism,
which can be used to create an eye-catching
image multiplication effect.
Displayer 250 operating modes
As already said, there are 2 operating modes: Static and Dynamic. Access is
gained via the 4-position “function” dipswitch, on the right looking at the
projector from the rear.
The combinations to which this switch gives access are as follows:
PIN 1 OFF Static mode
PIN 1 ON Dynamic mode.
When the fixture is used in Static mode, the remaining 3 pins have the following functions:
PIN 2 ON “rainbow” effect
PIN 2 OFF fixed colour
PIN 3 OFF no effect and fixed gobo
PIN 3 ON gobo rotation enabled (or fixed gobo positioning)
PIN 4 OFF 4-sided prism disabled
PIN 4 ON 4-sided prism enabled.
In static mode the image projected must be only the #1.
When the fixture is used in Dynamic mode, pins 2, 3 and 4 effect the following functions:
PIN 2 ON + PIN 3 OFF “rainbow” colour
PIN 2 OFF + PIN 3 OFF fixed colour
PIN 2 ON + PIN 3 ON timed colour change
PIN 2 OFF + PIN 3 ON no effect
PIN 4 OFF image wheel rotates at fixed speed
PIN 4 ON timed image change.
