Electrical Connections
1. The cable attached to your Traffic Director should have a green connector (part #CPSS-153)
attached to it. Eight colored 18 AWG wires, one bare drain wire, and a large red 12AWG wire
should already be connected from the cable to the connector.
2. Connect a ground wire to the interior empty terminal on the green connector.
(See diagram
above)
The corresponding terminal plugs into the outlet on the back of the controller and is
marked
BAT-
.
It is imperative that you supply a ground wire to the terminal marked
"BAT -" on the controller. You must not let the controller's case supply
ground. Use 12 AWG wire for all power and ground connections
3. Supply power for the unit from a
fused
,
+12 VDC source capable of delivering at least 15
amps of current (use a 20 amp fuse). Star recommends the use of an ignition switched
supply to avoid the possibility of draining the vehicle's battery should the unit be
accidentally left on.
4. Connect your power supply to the terminal on the green connector that corresponds to
the outlet on the back of the controller marked
BAT+
.
5. The lamp brightness will be somewhat diminished if a large voltage drop exists between
the vehicle's battery and the controller. If voltage drop is a problem, use a relay to
control a direct battery feed. A generic relay designed for automotive lamp service
should be available from most automotive stores for this purpose. If using a relay, don't
forget to
fuse the feed
and
signal wires
at their source, with appropriate values. It is
imperative that you supply a ground wire to the terminal marked "
BAT -
" on the
controller; you must
not
let the controller's case supply ground. Use 12 AWG wire for all
power and ground connections.
6. Your Traffic Director should now be ready to operate.
Please note: If you are connecting a TD93DLXT24 (which operates only on 24VDC) the
Input Power (and bypass power) would be 24VDC in the diagram above.
