INSTALLATION AND OPERATING INSTRUCTIONS FOR

Dual Motor Low Voltage Control (DMC)

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.

Installation

WARNING: To prevent electrical shock or damage to the Dual

Motor Low Voltage Control (DMC), do not apply power to the
DMC until all connections are complete. Make sure power is
turned of 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
efectués. Vériiez qu'aucun câble n'est alimenté avant
d'efectuer les branchements

Opening the Unit

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 ire, electric shock, or injury to
persons.

To open the unit, please follow these instructions and Figures 2,
3, and 4.

1. Remove the six screws that hold the cover plate to the box

(DO NOT REMOVE the 4 screws in the middle of the cover
plate; these hold the circuit board to the cover plate.)

See Figure 2.

2. Upon removing the screws, push the cover plate to the side
of the box. See Figure 3.

3. Rotate up and remove. See Figure 4..

Low Voltage Connections:

Wall Switch

1. Install wall switch where desired.

2. Use 3-conductor 2024 gauge wire to extend the switch wire
to the DMC location.

3. Connect the wire from the switch to the switch terminal as
shown in Figure 5.

CAUTION: Never apply more than 24 volts to the wall switch

terminal or the DMC will be damaged.

ATTENTION: n'alimentez jamais le commutateur mural avec

plus de 24 volts ou la commande double du moteur sera
endommagée.

Third Party Control System

A third party control system may be connected to the DMC by using
the wall switch terminal. The third party control system must provide
a momentary, dry contact closure of at least 1/2 second.

1. Use 3-conductor 2024 gauge wire to connect the third party
control system to the wall switch terminal.

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 more than 24 volts to the wall switch

terminal or the DMC will be damaged.

ATTENTION: n'alimentez jamais le commutateur mural avec

plus de 24 volts ou la commande double du moteur sera
endommagée.
