Green Sense Wiring - OPTICOM 764 Installation Manual

9.2 Green Sense Wiring

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.
Note:
•
Green sense inputs may be 89-135VAC, 57-63 Hz.
1. Locate and identify the load bay field wire connections (AC+) for each phase green in the traffic control
cabinet.
2. Determine the appropriate length of wires required to connect the auxiliary interface panel to the wiring
points in the load bay of the traffic control cabinet.
3. Wire gauges from 22 to 16 AWG may be used
4. Strip 1/4 inch (6 mm) of insulation from both ends of the wires being used.
5. Insert one end of each wire into the desired terminal of the auxiliary interface panel and tighten the
screw. (For example, Phase 1 green is labeled AC IN 1 on terminal block TB1.)
6. Repeat step 4 for all desired phase greens.
Note: Do not connect green sense wires to any phases that are not being used.
7. Route the wires through the traffic control cabinet to the AC side of the load switches in the load bay.
Install spade lugs on the wires.
8. Insert one wire at a time into the correct terminal in the load bay and tighten the screw.
9. Locate and identify the AC neutral connection in the traffic control cabinet.
10. Insert one end of the wire into the AC neutral terminal (AC COM on TB1) of the auxiliary interface panel
and tighten the screw.
11. Route the wire through the traffic control cabinet to the AC neutral terminal. Install a spade lug and
connect the wire to the AC neutral terminal.
12. Verify that your wiring is correct, and the connections are tight.
13. Verify that the green sense wires are connected correctly.
a) To do this, open the On-site software and press the current activity button, compare the current
greens displayed on the bottom of the window to the active greens indicated on the controller or
conflict monitor/MMU.
14. Reconnect any green sense wires that may be incorrect.
