(FTS 370d L-864/865 only)
Note:
Complete
instructions
for
installing
the
Marker
Interface
Enclosure, marker mounting brackets
and
MKR
370
L810
markers
are
provided with the marker kit. Refer to
“MKR 370 Wiring Instructions” (Part #
7119001)
for
specific
information
regarding cable connection to the MKR
370.
Wiring information is provided in the
following steps.
Figure 2-5 shows the
Marker Interface Enclosure with three
markers connected. Figure 2-20 shows a
system installation diagram. Figure 2-32
shows the recommended cable routing and
an internal wiring diagram for the Marker
Interface Enclosure.
Note:
The Marker Interface Enclosure
should be located at the marker tier
level. A pictorial detailing the mounting
of the Marker Interface Enclosure is
included with the Marker Kit installation
instructions (Drawing PN 7790107 or
7790108).
Wiring Procedure
1. Observing the procedures described
previously in “Flashhead Cable” and
“Securing the Cable”, install a 5’
service loop in the cable near the
marker interface enclosure.
2. Prepare the flashhead cable:
a. Remove 6 inches of the outer
jacket.
b. Remove the exposed aluminized
Mylar shield and any filler material
between conductors.
3.
Loosen the dome nut of one of the ¾”
cable strain reliefs located in the
bottom of the enclosure.
Route the
flashhead cable from the flashhead
through the strain relief and tighten the
dome nut.
4. Connect the three conductor flashhead
cable to the terminal strip TB1 using a
non-flared flat tip screwdriver:
a. Connect the red wire to one of the
two terminals on the top row
labeled DC+.
b. Connect the black wire to one of
the two the terminals on the top
row labeled DC-.
c. Connect the bare drain wire to one
of the two the terminals labeled
GND.
5. Loosen the dome nut of one of the ½”
cable strain reliefs located in the
bottom of the enclosure. Insert 12” of
marker cable through the cable strain
relief and tighten the dome nut.
6. Prepare the marker cable by removing
4 inches of the outer jacket and any
filler material between conductors.
7. Connect the marker cable to connector
J1 located on the marker interface
board:
a. Connect
the
red
wire
to
the
terminal labeled DC+.
b. Connect the black wire to the
terminal labeled GND.
8. Route the cable to the marker light
following the instructions supplied
with the marker kit.
9. Repeat steps 4-8 for the remaining
markers to be installed.
10. Install the flashhead cable from the
marker interface enclosure to the FH
370d by repeating steps 1-3.
NOTE:
A 5’ service loop should be
installed
for
each
flashhead
cable
section (SC 370d to Marker Interface &
Marker Interface to FH 370d) near the
marker interface enclosure.
