INSTALLATION
This manual covers installation for both the external SCB-100 and the built-in SCB-100. If you have the external SCB -100,
refer to diagrams 1, 2 and 3 for wire connections. If your screen has the SCB-100 built into the screen case, refer to
diagram 4 for wire connections.
The main power wires (100-240VAC) should always be separated from the low voltage wires. To do this, route the power
and motor wires into the housing using the knockouts on one end of the housing. The wall switch and RS-232 wires
should be routed through the knockouts on the opposite end of the housing.
Do not connect power to the SCB-100 until all other connections are complete.
Wall Switch
The SCB-100 has two manual switch ports. These ports are for dry contact closure only. Port 1 controls motor 1. Port 2
controls motor 2.
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 wall switch to the SCB-100 as shown in diagram 1.
CAUTION: Never apply voltage to the wall switch terminal or the unit will be damaged.
RS-232
The SCB-100 has two RS-232 ports. Port 1 and Port 2 can control either motor 1 or 2.
Both ports are marked with RX, G, TX.
RX-data being received into the SCB-100.
TX-data going out of the SCB-100.
G-ground.
12VDC Out
The SCB-100 supplies voltage to the optional NET-100 network adaptor. The center terminal is not used.
