Installing the low-voltage 3-button switch option
The optional Stewart Filmscreen low-voltage control (LVC) allows the use of
low-voltage wire to connect to the supplied 3-position 24V momentary wall
switch.
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 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
Refer to the diagram that is located on the white label inside the steel
housing, and to Figure 8.
1. Mount the low-voltage control box near the screen.
2. Connect the low-voltage control box to the screen by connecting
the screen motor power leads to the power strip terminal block
located on the circuit board of the control box.
3. Connect the low voltage control box to the AC power source by
connecting the AC line voltage to the power strip terminal block
located on the circuit board of the control box.
4. Connect the switch to the low-voltage control box.
Note:
A parallel connection to an outboard audio-visual switching network
can be made at this time. (optional)
