Caution

Professional techniques should be used when making any electrical connection. A qualified electrician should perform these procedures.

Be sure to follow all standard safety procedures for installing electrical devices.

Do not disassemble or alter the configuration of the motor or the unit's electrical connections. This may cause injury to you or damage to the product.

The electrical connection should be made only to the type of power source indicated on the marking label.

The motor requires standard AC input (unless an alternate voltage has been specified).

There are several kinds of switch controls available. Follow the installation procedure for the type of switch control you will install.

General suggestions for wiring:

 Soldering is recommended.

 The use of wire nuts is acceptable.

Preparation—Removing access panel

All connections are made to the electrical box on the side of the unit

(audience left). An access panel covers the electrical connections. To remove the access panel on the underside of the unit, remove the two hex screws. Refer to Figure 2. Replace the access panel after the electrical connections have been made.

Installing the low-voltage 3-button switch (standard)

The Stewart Filmscreen low-voltage control allows the use of low-voltage wire to connect to the supplied 3-position 24V momentary wall switch.

Note: When the low-voltage 3-button switch is ordered, the control box is pre-mounted at the factory.

Preparing the connection

Before making the electrical connections, you need:

 An available AC constant power source

 A 4-conductor switch hook-up cable (4-conductor bell wire or category 5 cable is typically used for long runs)

 Cat 5, multi-conductor unshielded, or similar type electronic cable can be used to connect the 3-button switch to the LVC. The recommended wire gauge is 20 to 24 AWG. Use plenum-rated cable when required.

Making the connection

Figure 3 illustrates the connections.

1. Connect the 4-conductor cable to the connection harness coming from the J-box labeled “switch input.”

2. Connect the hookup cable to the 3-button switch.

3. Connect the main AC power source to the the J-box labeled

“main AC power connection.”

4. A parallel connection to an outboard audio-visual switching network can be made at this time. (optional)

Connecting the screen trigger interface option

The optional 12V screen trigger interface enables up and down operation of the screen in conjunction with a projector, tuner, VCR, cable box, or switched AC outlet.

Once the AC power is connected to the screen’s J-box, an electrician is not needed to connect the screen trigger interface to the power source.

Note: An optional 12V DC transformer is used if there is no 12V power source from the projector or AV control center.

Preparing the connection

Before making the electrical connections, you need:

 An available AC constant power source installed near the screen

Making the connection

Figure 4 illustrates the connections.

1. Attach the 12V trigger wire to the jack on the J-box.

2. Connect the main AC power source to the the J-box labeled

“main AC power connection.”
