(Wiring CONT’D)
Wiring for Optional Automatic Activation
1. The Traffic Director may also be wired to automatically bypass the TD77-2 (or TD77-2-24)
controller On/Off switch and turn on through the use of an alternate power source (i.e. lightbar
switch, siren switch, reverse switch, etc.).
2. When you apply +12VDC to the 12AWG wire supplying the stick with power, you will bypass
the On/Off switch and activate the Traffic Director. When activated, the Traffic Director will
automatically enter the "Warn" pattern.
Please note: If any other lights are connected to
this “bypass” circuit they will activate any time the traffic director is powered up unless
they are isolated in some way (e.g. diode or relay).
Jumper Settings
When the control box jumper is in the "Phantom Mode" setting (see diagram on next page)
only the center 6 arrays will be utilized during the Left, Center Out, and Right patterns.
The outer two heads or arrays will flash alternately.
The TD77-2 control box and the ULB42-TD-2
control box are identical except for the factory
default setting of a jumper located inside the
control box. This jumper will control the output of
the two arrays on each end. The TD77-2 comes
with the jumper defaulted for standard operation.
Optionally you may wish to set the jumper so that your arrowstick operates in "Phantom" mode. In
the “Phantom” mode, the end lights are not part of the “traffic directing” patterns. When the Alt
button is pressed, both of the end lights will flash back and forth in a “warn” type display. (In the
"standard" mode, the end lights will follow the normal “traffic directing” pattern you select on the
control box.) If you wish to operate your traffic director in Phantom Mode, (6-head traffic directing),
follow the instructions below to remove the cover and change the jumper setting. If the standard
mode is acceptable, skip this section
.
TD77-2 or TD77-2-24
Please note: If you are connecting a TD93DLXT24 and TD77-2-24 (which operate only
on 24VDC) the bypass power would be 24VDC in the diagram above.
