j . splice and connection
to the pullbox nearest the roadway loop serisor each lead and
lead-in conductor shall be stripped back and spliced using a
pressure type wire connector applied with a crimping Mole.
together with multiple loop sensor wires as required for the
particular installation. _ Multiple loop sensors shall be
identified (colored tape or fiber tags) at eacK location where
more that one ( 1 ) loop sensor occupies a pullbo . The lead-in
-splicing shall be staggered to prevent contact with each other.
Each crimped splice shall be soldered and insulated, the
itsulation material shall be heat-shrinkable pol olefin. The
shielded lead-in cable outer jacket and shield shall be
stripped back sufficiently to ensure that the shield cannot
cote into contact with the splices. The entire area shall be
leveled using electric insulating patty and then covered with a
thick wall, interior sealant coated, heat shrinkable tubing.
The tubing shall extend at leas. 2 inches beyond splices in both
directions before shrinking the tubing. The tubing shall be
shrunk with a heat source, designed for the purpose, delivering
at least 250 degrees F ( 121 degrees C) until the tubing sealant
protrudes out both ands and is apparent completely surrounding
troth the lead-in cable and the loop sensor ends.
The lead-in conductor's shall be connected to the appropriate
terminals in the controller cabinet, by using crimped End
soldered terminal ends.
k. Testing of Loops
The following test procedure shall be performed in the presence
at the Engineer before and after the loop sensor is sealed in
the pavement as detailed below. The cost of equipment, labor,
and materials to perform such testing and similar retesting
following repairs, replacement, or adjustment of any detector
within the project area shall be included in the price bid for
the 'traffic Control Signal installation for that locatior'.
After installation of wire loop sensors in the roadway and
installation of shielded lead-in connecting the loop sensors to
the controller cabinet, each loop sensor and lead-in combina-
tion shall be tested (at the controller cabinet, each loop
sensor and lead-in combination shall be tested (at the
controller cabinet) for proper installation. The resistance
from lead to lead of the sane loop shall not exceed 3 ohms per
1,000 feet as measured by a- high quality meter suitable for
measurements of law resistance .

Stern 816.01 (continued )
A megohm meter test at 500 volts D.C. shall be trade between the
two leads of a 1acp/lead-in combination temporarily spliced
together, but otherwise disconnected from all terminals, and
the shield drain wire and then the earth ground connection.
These resistances should be at least 100 megohms. The lowest;
acceptable value sha.11 he greater than 50 megohms under worst
case conditions.
A megohm meter test at 500 volts D.C. shall be made between
lead-in shield and the earth ground rod. This resistance
should be at least 100 megohms. The lowest acceptable value
shall be greater than 50 megohms under worst case conditions .
If any loop sensor and lead-in combination fails to pass any
one of the four tests, it shall be repaired and then re-tested
on two occasions at least two weeks apart, and then shall pass
on each re-test occasion. if the loop sensor lead-in combina-
tion does not pass all these retests, a new loop sensor bnd or
lead-in shall be installed, and shall pass these tests, at no
additional cost.
Ater the above tests have been satisfactorily completed, all
.loop sensor shielded lead-in inductances shall be measured and
a written report of the results shall be filed with the
Engineer and a copy stared with the "box prints" at the 'inter-
section along with a copy of the ground electrode, resistance
tests required by MDPW 813.62B.
Attention is directed to paragraph 815. 64 of the 1973 Standard
Specifications, sections of which apply to these specifications .
1. Diagrams and Manuals
Wiring and schernatic diagrams, descriptive pants lists, and
instruction and maintenance manuals shall be provided for all
items fcrnizhed under these specifications. Tables, charts or
data for use in designing loops of -various sizes and configura-
tions, other than specified below, shall be provided. Two ( )
complete sets of diagrams, manuals and pertinent information
stall be furnished with each. contract.
M. Sealing of Wire Lcg2 Sensors in Pavement
With special non -metallic nozzle, insert nozzles into sawcut
down to level wires and extrude sealant while moving the
applicator and nozzle smoothly along the length of the loop
wire. Fill to the level 1/8-inch below the surface..
When using solvents for. clean-up, it is essential that proper
precaution for handling such material be observed.
