FOIRE AUX QUESTIONS - HORIZON ELECTROL DA-LITE

Comment installer l'écran HORIZON ELECTROL ?

Déballez l'écran, vérifiez les mesures, montez le boîtier entre les solives en le mettant de niveau. Fixez les supports avec des tirefonds. Consultez la section Installation de la notice pour les détails.

Comment connecter le câblage de l'interrupteur mural ?

Acheminez les deux câbles T6 de l'interface bus vers le boîtier de l'interrupteur. Branchez-les sur l'adaptateur T6 2-à-1. Reliez ensuite un câble T6 court à l'adaptateur et à l'arrière de l'interrupteur mural 6 boutons. Voir le schéma de câblage dans la notice.

Quels sont les formats d'image préréglés ?

Les quatre formats préréglés sont : NTSC (1.33:1), HDTV (1.78:1), Letterbox (1.85:1) et Anamorphic (2.35:1). Chacun est accessible via un bouton dédié de l'interrupteur.

Comment ajuster la position d'arrêt de l'écran pour un format personnalisé ?

Coupez l'alimentation, débranchez le câble T6 du moteur 2, puis retirez le câble T4 'moteur 2' de l'interface bus. Rebranchez l'alimentation, utilisez le bouton 1 pour descendre l'écran à la position souhaitée, appuyez sur Stop, puis maintenez enfoncé le bouton 2, 3 ou 4 pendant 5 secondes pour enregistrer. Rebranchez les câbles.

Comment ajuster la position du masque ?

Coupez l'alimentation, débranchez le câble T4 'moteur 1' de l'interface bus et le câble T6 'moteur 1' de l'adaptateur. Rebranchez l'alimentation, utilisez le bouton 1 pour descendre le masque à la position voulue, appuyez sur Stop, puis maintenez enfoncé le bouton 2, 3 ou 4 pendant 5 secondes. Rebranchez les câbles.

L'écran ne descend pas, que faire ?

Vérifiez d'abord le fusible ou le disjoncteur du circuit. Assurez-vous que l'alimentation arrive à la boîte de jonction et à l'interface bus. Contrôlez les connexions des câbles T4 et T6. Si le moteur bourdonne sans bouger, il peut être bloqué ; coupez l'alimentation et tournez le rouleau à la main.

Le moteur s'arrête après une utilisation prolongée, que faire ?

C'est normal : le moteur a une protection thermique. Laissez-le refroidir pendant environ 15 minutes avant de réutiliser l'écran. Évitez les cycles continus excessifs.

Quelles précautions de sécurité faut-il respecter ?

Lisez toutes les instructions avant utilisation. Ne placez pas le cordon d'alimentation dans une zone de passage. N'utilisez pas de rallonge de calibre inférieur. Ne démontez pas l'appareil ; confiez les réparations à un technicien agréé. Respectez les consignes de câblage électrique locales.

Quelle est la fonction de chaque bouton de l'interrupteur ?

Le bouton haut remonte l'écran et le masque. Stop arrête tout mouvement. Les boutons 1 à 4 sélectionnent respectivement les formats NTSC, HDTV, Letterbox et Anamorphic. Appuyez et relâchez rapidement ; ne maintenez pas plus de 3 secondes pour éviter de reprogrammer.

Comment réinitialiser les positions de montée et de descente ?

Retirez le couvercle de l'interface bus. Débranchez le câble T4 du moteur à régler et branchez-le sur le connecteur RJ22 en haut à gauche de l'interrupteur. Utilisez le dipswitch 3 positions : bas pour régler la limite basse, haut pour la limite haute. Maintenez le bouton correspondant pour déplacer l'écran, puis replacez le dipswitch au milieu. Rebranchez le câble à l'interface bus.

IMPORTANT SAFETY INSTRUCTIONS

When using your video equipment, basic safety precautions should always be followed, including the following:

1. Read and understand all instructions before using.
2. Position the cord so that it will not be tripped over, pulled, or contact hot surfaces.
3. If an extension cord is necessary, a cord with a current rating at least equal to that of the appliance should be used. Cords rated for less amperage than the appliance may overheat.
4. To reduce the risk of electric shock, do not disassemble this appliance. Contact an authorized service dealer when repair work is required. Incorrect reassembly can cause electric shock when the appliance is used subsequently.
5. The use of an accessory attachment not recommended by the manufacturer may cause a risk of fire, electric shock, or injury to persons.

SCREEN ADJUSTMENT

ADJUSTING THE SCREEN

The motors on the Horizon Electrol® have been preset to four different screen formats based on your screen size. They are 1.33:1, 1.78:1, 1.85:1 and 2.35:1. It is possible to adjust these formats for your particular needs. If you want to change formats we suggest you contact your Da-Lite Dealer to make the adjustments for you.

The mask surface and the projection screen must be adjusted separately. The following instructions walk you through this process.

SCREEN ADJUSTMENT (MOTOR 1)

1. Make sure the power is disconnected to the screen before starting.
2. Remove the cover plate from the wall switch, and then remove the switch from the box.
3. Unplug the T6 cable marked motor 2 from the T6 adapter.
4. Locate the bus interface control. It is located on the motor end of the screen case. Remove the screw that holds the cover shut. Slide the cover back and unplug the T4 wire marked motor 2.
5. Reconnect the power to the screen.
6. Press the button marked 1 to lower the screen. When the screen reaches the desired level press the stop button. If you go past the desired position, press the stop button to stop the screen and then press the up arrow to return the screen to a position above the new stop point and try again until the screen stops at the new position. The new stop point can now be assigned to whichever format location you want, button 2, 3 or 4. Press and hold in the chosen button for 5 seconds, then release.
7. The new stop position is now recorded for the selected button. Repeat this process for any other changes to the remaining 2 locations.
8. Make sure the power is disconnected to the screen, then insert the T4 cable marked motor 2 in the jack it was disconnected from on the bus interface control and reconnect the T6 cable to the T6 adapter.

MASK ADJUSTMENT (MOTOR 2)

1. Make sure the power is disconnected to the screen before starting.
2. Unplug the T4 cable marked motor 1 from the bus interface control.
3. Unplug the T6 cable marked motor 1 from the T6 adapter.
4. Reconnect the power to the screen.
5. Press the button marked 1 to lower the mask. When the mask reaches the desired level press the stop button. If you go past the desired position, press the stop button to stop the mask and then press the up arrow to return the mask to a position above the new stop point and try again until the mask stops at the new position. The new stop point can now be assigned to whichever format location you want, button 2, 3 or 4. Press and hold in the chosen button for 5 seconds, then release.
6. The new stop position is now recorded for the selected button. Repeat this process for any other changes to the remaining 2 locations.
7. Make sure the power is disconnected to the screen, then insert the T4 cable marked motor 1 in the jack it was disconnected from on the bus interface control, shut the cover and fasten the screw.
8. Reconnect the T6 cable marked motor 1 to the 2-1, T6 adapter jack.
9. Reinstall the wall switch into the box and attach the cover plate.
10. Reconnect the power to the screen.

LIMIT CONTROL ADJUSTMENT

This procedure will reset the stop positions for the "up" button and button 1. If you have a wall switch with just two T6 connectors on the bottom you will need to use a separate 3-button switch for this operation. Otherwise you will use the wall switch that controls the bus interface unit. Below is a diagram of switch you will use.

1. Remove cover screw from bus interface unit located on the motor end of screen case.
2. Locate the T4 wires coming from the motors to the bus interface (see wiring diagram).
3. Unplug the T4 wire of the motor to be adjusted from the bus interface unit and plug it into the top left RJ22 4-pin connector of wall switch.
4. Locate the 3-position dipswitch in top right corner of switch. To adjust the down limit flip the switch in the down direction. Press and hold the 1 button on the switch to run the screen down to the desired position. Release the button to stop the screen.

NOTE: If you push the down button and the screen runs in the up direction press and release the stop button. Then press the down button again. This should reverse the motor.

1. When the screen is at the desired location flip the dipswitch back in to the middle position.
2. To adjust the up limit (the screen should be in down position first) flip the dipswitch to the up direction. Press and hold the up button to run the screen to the desired top position.
3. When the screen is at the desired location flip the dipswitch to the middle position. Now press 1 button to make sure the screen stops at the new down position. Then press the up button and watch carefully to make sure it stops in the new up position.
4. Unplug the T4 wire from the switch and plug it into the SAME location you unplugged it from the bus interface unit.
