Confirmation Light Wiring; Confirmation Light Wiring With Load Switch Interface - OPTICOM 764 Installation Manual

9.3 Confirmation Light Wiring

The Opticom™ Infrared System Model 768 Auxiliary Interface Panel confirmation light outputs are used to
activate customer-provided confirmation lights in response to an approaching high priority vehicle. The
behavior of the confirmation lights is programmed using the On-site software.
Each confirmation light is directed toward an approach in the intersection. That approach direction
corresponds to one of the channels on the Model 764 phase selector. The installer determines the
relationship between approach direction and channel by the detector wiring.
Verify the relationship between the approach directions and channels before starting the installation and
then configure the behavior of the confirmation light using the On-site software

9.3.1 Confirmation Light Wiring with Load Switch Interface

WARNING
This procedure may expose you to AC
voltage and the risk of electric shock or
electrocution. Turn off the AC mains and
use accepted and recognized safety
precautions to avoid exposure to the risk of
electric shock or electrocution. Electric
shock may cause severe injury or death.
1. Locate and identify the input connections in the traffic control cabinet for each load switch that
switches power to the confirmation lights.
2. Determine the appropriate length of wire required to connect the auxiliary interface panel to the
wiring points for the load switches.
3. Strip 1/4-inch of insulation from both ends of the wires being used.
4. Wire gauges from 22 to 16 AWG may be used.
5. Insert one end of each wire into the desired terminal of the auxiliary interface panel and tighten the
screw. Connect wires to terminals A CFRM, B CFRM, C CFRM, and D CFRM. See Figure 5-16.
6. Route the wires through the traffic control cabinet to the load switches in the load bay.
7. Install spade lugs on the wires and insert one wire at a time into the correct terminal in the load bay and
tighten the screws.
8. Connect a wire to one of the LOGIC COMMON terminal of the auxiliary interface panel. Install a spade
lug on the other end of the wire and connect it to the traffic controller logic ground. See Figure 5-16.
9. Connect the controller +24 VDC power source to each of the four confirmation light load switches.
10. Complete the configuration light interface wiring and field wiring as shown in Figure 5-16.
11. Verify that your wiring is correct, and the connections are tight.
12. Select the appropriate confirmation light pattern using the On-site software. See the On-site help file
