This Screen Winch System is made to lift the screens models COMPACT – MAJOR –
ELLIPSE and E-LITE manufactured by Euroscreen SRL.
In order to mount this winch system and the projection screen, please read carefully the
following instructions:
1. First of all fix to the ceiling the 3 brackets for the screen winch, taking care that these
3 brackets are perfectly aligned and also mounted horizontally. From the central bracket,
the left and right brackets have to be mounted at 98 cm distance from the central bracket.
(see Fig. 1). Each bracket has to be mounted to the ceiling like showed in Fig. 2 with 4
suitable screws or bolts (fixings are not supplied).
2. Fix the screen winch (seen from the front with the power cable at the right side of the
housing) at the brackets as shown in Fig. 3. First move the clamps close to the winch
housing and tighten the nuts inside the bracket as shown in Fig. 3. Now in order to secure
the clamps, tighten the 2 front screws of the bracket like shown in Fig. 4.

3. Now connect the power cable of the screen winch to the 220V mains. The winch is
equipped with a safety device that will prevent the roll down of the winch in case that the
traction parts of the motor will fail.
For the electrical connection of screen winch system, safety device and screen, see
schematic diagram below.

IF, AT THE FIRST OPERATION, THE SCREEN WINCH WILL NOT ROLL DOWN, IT IS
LIKELY THAT THE SAFETY SYSTEM IS IN LOCKED MODE; THIS CAN BE CAUSED
DUE TO ROTATION OF THE SCREEN WINCH DURING TRANSPORT.
In order to check the safety system, follow the next steps:
- Remove the safety system unscrewing the four screws and pull out it from the
winch.
- Manually rotate the central square hole by using your finger, in both directions,
taking care that position TOP is on the upper part (see picture below).
- Reposition the safety system in the original position, taking care to keep position
TOP is on the upper part and fix it again with the four original screw.
4. Take now the beam and position it under the screen winch, taking care that the front
(indicated) of the beam is in the correspondence of the front of screen housing.
Take the steel cables coming out of the screen winch and go through the eyebolt and fix
them to the L-form bracket, at the beam as shown in Fig.6.
5. At the bottom side of the beam you have to mount the remaining 3 brackets (see Fig. 5).
Take care that the left bracket has to be mounted at 20 cm. from the left end side of the
beam and the right racket has to be mounted at 20 cm. from the right hand side of the beam.
Now fix the screen housing at these brackets taking care that the power cable of the screen
is at the right side of the housing.

6. With the winch completely rolled up, you have to adjust the screws fixed on the L-form
brackets, which are fixed on the beam (see fig. 6) so that the beam is perfectly horizontal
and check also that the steel cables from the winch to the beam are perfectly in vertical
position. In case the steel cables are not perfectly vertical, please move the metal ring on
the beam, left or right in order to position the steel cable vertically. In case you have moved
the eyebolt, check carefully that you fix it again sturdy to the beam.
7. To connect the mains 220V to the screen, you have to use the cable coiler that is included
in the packaging. Mount the cable coiler to the ceiling behind the screen winch housing at
the right side (see Fig. 6B), using suitable screw anchors (fixings are not supplied).
Fig. 6B – CABLE COILER
8. Now fix at the rear side of the beam the L form bracket as indicated in Fig. 7 and fit the
output power cable of the screen winch through the bracket and fix it with two wire clamps
as shown in Fig.7 in order that it remains fixed when the beam moves up and down.
At this step, you have to connect to the incoming power cable of the cable coiler fixed at the
ceiling a plug and connect it to the mains up in the ceiling.

9. Now fix the power connector box to the beam the as shown in Fig. 8 and connect the end
of output power cable of the cable coiler to the power cable that comes out of the screen
housing.
10. At this step, you have to connect the incoming power cable of the cable coiler to the
mains 220V (see page 3).
WARNING: Once you have installed the product, when you switch on the
Screen Winch System you will hear a rhythmical ticking which means that the
safety device is working properly.

END STOP ADJUSTMENT OF THE SCREEN WINCH
WARNING: THE END STOP ADJUSTMENT HAS TO BE DONE CAREFULLY,
OTHERWISE THE SCREEN WINCH CAN BE DAMAGED PERMANENTLY.
THE UPPER END STOP IS FACTORY PRESET AT THE HIGHEST POSSIBLE HEIGHT
– DO NOT ATTEMPT TO RAISE IT MORE.
THE BOTTOM END STOP IS FACTORY PRESET AT A FEW CENTIMETRES OF DROP.
Should the screen winch roll down more than 1 mt., check the status of the motor
switchers.
ON THE STEEL CABLE MOTOR HAND SIDE OF THE SCREEN WINCH SYSTEM,
THERE IS, AT 680 CM. DROP, A WHITE TAPE WHICH INDICATES THAT THE WINCH
HAS NEARLY REACHED THE MAXIMUM EXTENT, THEREFORE STOP IMMEDIATELY
THE WINCH.
AT 700 CM. DROP, A SECOND WHITE TAPE IS APPLIED ON THE SAME STEEL
CABLE; THIS INDICATES THAT THE MAXIMUM EXTENT OF THE WINCH HAS BEEN
REACHED. DO NOT GO FURTHER.
In case the bottom end stop is set lower than 7 mt., there is a DANGER OF FALLING
DOWN OF THE PROJECTION SCREEN HOUSING AND PERMANENT DAMAGE OF
THE SCREEN WINCH SYSTEM.
Once you receive the winch, you will find the switchers in locked position (CHECK
BEFORE ACTIVATING).
In case, after installation, the end stops of the Screen Winch System need to be changed,
please, proceed as follows:
- at the right side of the Screen Winch System, in the lower part of the cabinet you will find
two round holes;
- as shown in the figure below:
- “1” indicates switcher for setting of the bottom end-stop position
- “2” indicates switcher for setting of the upper end-stop position

9
WARNING: Once the switchers are unlocked, the motor can move freely without
any end stop set.
- In order to modify the lower end-stop position, move the switcher “1” in position “0”,
move the screen winch to the desired height and set switcher “1” in position “I”, as shown
on the figure above.
- In order to modify the upper end-stop position, move the switcher “2” in position “0”,
move the screen winch to the desired height and set switcher “2” in position “I”, as shown
on the figure above.
DO NOT TRY TO HIGH UPPER END-STOP, OTHERWISE THE SCREEN WINCH
SYSTEM CAN BE DAMAGED PERMANENTLY AND THE WARRANTY WILL BE
VOIDED.
WARNING: do not change the end stops of the projection screen, otherwise you will
invalidate the warranty on the screen.
