Mounting the TA56LED Lightbar:
WARNING!When the traffic advisor is mounted to the rear of
the vehicle, the cable exit must be on the
passenger side. If not, the flash pattern sequence
you choose on the control head will be incorrect.
For example, a left flashing pattern will flash right.
1.
The TA56LED attaches to the vehicle by the four 2” bolts
extending from the rear of the housing. Position the unit in its
proposed mounting location to ensure that it fits properly.
With the unit in place, use an awl or other suitable tool and
scribe the areas to be drilled.
2.
Remove the unit from its mounting area and, using an
appropriately sized drill bit, drill a hole in each of the areas
scribed in the previous step.
3.
Return
the
unit to its
mounting
location and
using
the
supplied
hardware,
secure
the
unit to the
vehicle.
The Tactrl1 Control Head
is used to operate the TA model
represented in this manual. A four function rotary switch selects
from: left arrow, right arrow, split arrow, or flash pattern. The Dip
switch on the rear panel selects the choice of the following
patterns (See Dip Switch Specifications):
• One Lamp Sequence to Double Flash
• One Lamp Sequence to Triple Flash
• Two Lamp Sequences
• Three Lamp Sequences
• Four Lamp Sequences
• Sequence On/Sequence Off
• Sequence to Solid
• Solid Arrow
A Center-Off Rocker Switch is used to turn the unit On and Off, in
either High or Low power mode. The Tactrl1 also features an
LED status display that provides a visual indication of the current
light pattern (Fig. 1).
Mounting Control Head:
1.
Position the bail strap in the selected mounting location.
Using an awl or other suitable tool, scribe the surface where
the mounting holes are to be drilled.
2.
Carefully drill the mounting holes in the areas scribed in step
one. The size of the drill bit should be determined by the size
of the mounting hardware (customer supplied) and the
thickness of the mounting surface.
3.
Using the customer supplied mounting hardware, secure the
bail strap to the mounting location.
NOTE: There are two sets of holes on either side of the Bail
Strap that can be used when installing the Tactrl1, to posi-
tion the control head at two different heights (see Fig. 2).
4.
With the bail strap in place, insert the carriage bolt along with
the external tooth lockwasher into the assembly hole from
the inner side of the Bail Strap as shown in figure 2.
5.
Place the split lockwasher and the acorn nut on the
protruding bolt on the outer side of the bail strap. Loosely
secure the acorn nut to the carriage bolt.
6.
Slide the control head onto the carriage bolts. Once it is in
the desired position, tighten the acorn nuts until the unit is
firmly secured.
Wiring the Traffic Advisor System:
1.
Insert the 3-position connector into the back of the control
head (see Fig. 3). Extend the RED and BLACK wires to the
battery.
2.
Connect the RED wire to one end of a user supplied fuse
block.
DO NOT
connect this unit to the battery yet!
3.
Connect the BLACK wire to the vehicle’s chassis ground.
4.
Extend and connect the WHITE wire to the dash board light
circuit. or an electrical connection that is live when the
vehicle is turned on.
5.
With the control head wired, route the cable from the TA to
the control head.
6.
Following the pin chart (Fig. 4), insert the contact wires into
their given positions. Check the wire’s retention fingers by
pulling back on them with a force of 1 or 2 lbs. to make sure
that they are holding the contact.
7.
Plug 12-position connector into the back of the control head.
The installation of your Traffic Advisor System will be complete
after the fuse block wire is connected to the POSITIVE (+)
terminal of the battery. After this connection has been made,
inspect the fuses at the control head and at the battery. If either
of these fuses are blown, carefully inspect all of the circuit wires
and make sure they are wired correctly. Replace the blown fuses
with one of an identical amp rating as the original. If these fuses
blow after installation or activation, contact Whelen Engineering
Technical Support.
