DISCLAIMER 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.

PRE-INSTALLATION
The low voltage control (LVC) housing is divided into 3 compartments. the compartment labeled “Low Voltage
Connections” is where you will connect the wall switch or a central control panel. The compartment labeled “AC
Power Connections” is where the main power and motor wire connections are made. The center compartment
only requires access when connecting an infrared or radio frequency remote receiver.
Wall Switch
WARNING: This unit must be used with the
enclosed switch. DO NOT USE the rocker switch
included with screen.
AVERTISSEMENT: Cette unité doit être utilisée
avec l'interrupteur fourni. NE UTILISEZ PAS
l'interrupteur à bascule fourni avec l'écran.
1. Install wall switch where desired.
2. Use 3-conductor 20-24 gauge wire to extend the switch
wire to the required length.
3. Connect the wire from the switch to the wire labeled
“wall switch”. Refer to diagram 1.
CAUTION: Never apply voltage to the wall switch
lead or the LVC will be damaged.
ATTENTION: N'appliquez jamais une tension aux
fils du commutateur mural sinon le tableau de
contrôle basse tension sera endommagé.
Control Panel
A control panel may be connected to the LVC by using
the wall switch wire lead. The control panel must
provide a momentary, dry contact closure of at least 1/2
second.
1. Use 3-conductor 20-24 gauge wire to connect the
control panel to the wall switch lead.
2. A momentary closure across the white and red wires
will be an “up” command.
3. A momentary closure across the white and black wires
will be a “down” command.
4. A momentary closure across the white, red and black
wires will be a “stop” command.
CAUTION: Never apply voltage to the wall switch
lead or the LVC will be damaged.
ATTENTION: N'appliquez jamais une tension aux
fils du commutateur mural sinon le tableau de
contrôle basse tension sera endommagé.

WARNING: To prevent electrical shock or damage
to the LVC, do not apply power to the LVC until all
connections are complete. Make sure power is
turned off on all wires before making connections.
AVERTISSEMENT: pour éviter tout choc
électrique ou d'endommager le tableau de
contrôle basse tension, n'alimentez ce dernier
qu'une fois tous les branchements effectués.
Vérifiez qu'aucun câble n'est alimenté avant
d'effectuer les branchements.

Symptom Cause Solution
Screen will not operate.
No power to LVC unit. Turn on power to LVC input. Measure voltage across
black and white input leads.
Incorrect wiring. Recheck all wiring for proper installation. Check all wire
nut connections.
Low voltage circuit damaged due to
voltage input.
The wall switch terminal is for dry contact (no voltage)
input only. Applying voltage to this terminal will damage
the LVC.
LVC controller lock-up.Locate breaker for screen and turn o power.
Wait one minute and re-activate circuit.
Radio frequency remote
does not work.
Weak battery in transmitter.Replace battery.
Infrared remote does not
work.
Weak battery in transmitter. Replace battery.
Receiver incorrectly positioned.Receiver must be unobstructed and located in direct
line with the transmitter..
Fluorescent light interference. Remote receiver should not be placed near
fluorescent lights.
Screen runs in the wrong
direction.
Red and black wires are reversed on motor or
wall switch terminals.
Turn o power to LVC. Reverse the red and black
wires on either the motor terminals or the wall switch
terminals. Changing either one will change the
direction of motor travel. Do not change both.
NOTE: The LVC will shut off power to the screen motor 5 minutes after the motor stops turning. Push the up or down
button to reactivate the LVC relays.
