ARROW STICK OPTION JUMPERS
The TDC850 controller that is shipped with the LCS881 has been designed so that it
can operate three different styles of traffic directors:
•
Independently Switched Heads:
Each Head is independently controlled by a
ground-side switched wire.
•
3-Wire Logic Controlled Heads:
Left, Right, and Warn functions are controlled
by delivering power to 3 separate wires.
Center-Out function activated by delivering
power to both Left and Right functions
(wires) at the same time.
•
4-Wire Logic Controlled Heads:
Specifically designed for the DL15-30W.
Power wire activates Warn function. Right,
Left, and Center-Out functions controlled by
delivering low current to 3 separate wires (in
addition to Power wire).
Please review the instructions that came with your traffic director and then
reference the corresponding section(s) in this manual for the type of traffic director
that you will be installing.
