NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) May 1, 202 4 VOLUME 4 MANUFACTURING .
A.General. Fabrication shall be such that performance will not be impaired after the equipment has been subjected to shock and vibration caused by normal installation, transportation and maintenance handling. Particular attention shall be given to neatness and thoroughness of soldering, wiring, welding, plating, riveting, finishes and machine operations. All parts shall be free from burrs and sharp edges or any other defect that could make the part or equipment unsatisfactory for the operation or function intended in this specification. Modules shall be designed such that major portions may easily be replaced. Modules of unlike functions shall be mechanically keyed to prevent insertion into the wrong socket or connector. All modules and assemblies shall be clearly identified with name, model number, serial number and any other pertinent information required to facilitate equipment maintenance. They shall be readily accessible for inspection and maintenance, using simple hand -held tools and standard meters.
B.Housing. The sign enclosure including doors and access panels shall be designed and constructed so as to present a clean, neat appearance; be smooth with exterior corners rounded; be weat herproof and vandal -resistant; and be free of burrs, blemishes and unspecified holes. Drainage holes shall be drilled near each corner of the base of the enclosure. The enclosure shall have internal lighting sufficient for all maintenance activity requ irements of the VMS and 120 volt power receptacles every 10 feet mounted on the rear interior panels. If the variable message sign is designated as "walk -in," then its access door shall be a minimum of 24 inches wide x 60 inches high.
C.Environmental .
1.Temperature. Internal temperature shall be continuously monitored whenever electric power is applied to the sign. The internal temperature of the enclosure shall be reported to the local and central controller upon request. Ventilation shall be automatically turned on and off at internal temperatures specified in the Proposal . Exhaust and intake ports shall be protected by filter screens against moisture, dust and insect intrusion. The ventilation system shall be sufficient to circulate three times the volume of air inside the enclosure per minute. Multiple fans or blowers shall be used to provide the specified venting and shall be located within the enclosure to minimize heat stratification.
2.Adverse Conditions. The equipment shall meet all of its specified functions during and after subjection to any combination of the following conditions:
a.Ambient Temperature. Range of -22OF to +145OF.
b.Temperature Shock. 60OF per hour, during which the relative humidity shall not exceed 95%.
c.Relative Humidity Range. 0 to 95% over the temperature range of 4 0OF to 110OF.
d.Moisture Condensation. On all surfaces.
3.Ambient Light. The variable message sign shall be equipped with light sensors so that the display shall be able to automatically adapt its level of light output to maintain readability under varying ambient light conditions. There shall be a minimum of eight (8) levels of dimming, linearly spaced from ni ghttime to daylight brightness. The sign =s automatic dimming control shall be overridable by central control. The dimming circuitry shall automatically compensate for
730-27 Permanent Variable Message Signs
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) May 1, 202 4 VOLUME 4 variations in the AC line voltage to maintain the light output constant for the selecte d brightness level. The levels of lighting shall produce luminance measured on the optic axis, as follows:
a.Daylight. A minimum of 14 candela per pixule for typical daylight environment.
b.Nighttime. Between 1.5 and 2 candela per pixule for nighttime environment.
D.Electrical Protection. The equipment shall contain readily -accessible, normally resettable or replaceable circuit protection devices (such as circuit breakers or fuses) for equipment and power source protection.
E.Electronic Components. All components shall be UL listed. All printed circuit boards shall be FR4 or G10 fi berglass epoxy material, with 2 oz. copper, double -sided with plated through -holes. All etched connector fingers are to be plated with a minimum thickness of 100 micro -inches of gold over nickel. Board connectors that are not an integral part of the printed circuit are to be plated w ith a minimum thickness of 15 micro -inches of gold over nickel.
F.Sign Face. In order to increase contrast, the pixules shal l be arranged on a black, non -glossy background. All electronic components visible from outside the sign shall be of black color or coated with black, non -glossy paint. The front of the sign shall be enclosed by a protective, weathertight face, 1/4 inch thick. Variable spacing between letters shall approximate the recommended spacing for 18 inch Series E sign text found in the Federal Highway Administration Standard Alphabets for Highway Signs. DESIGN CRITERIA. Design loads used in the design of the connection and mounting elements of the sign enclosure shall be as specified in the most current AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals . SUBMITTALS. When details of the connection of the Permanent Variable Message Sign to the sign structure are not included in the Contract Documents, the Contractor shall submit shop drawings to the DCES for approval, detailing how to mount and connect the variable mess age sign enclosure to the structure. Shop Drawings shall be submitted in accordance with the SCM. Shop Drawings may be submitted electronically to dces.metals@dot.ny.gov . If t he shop drawings are approved by the Department, the contractor will be notified by electronic mail. DELIVERY AND INSTALLATION . The contractor shall deliver, store, handle, and install all materials and equipment in such a manner as not to degrade quality , serviceability or appearance. Material to be stored shall be stored in a clean and dry location free from construction dust, precipitation, and condensing moisture. Any part of the equipment damaged during transportation, handling, or installation shall be repaired, or if determined by the Engineer as unfit for use in the finished work, shall be removed from the site and replaced by the Contractor at no additional cost. All materials shall be delivered and stored in the manufacturer ’s original unopened pr otective packages and protected against soiling, physical damage, or wetting, before and during installation. Unloading and unpacking of all materials shall be done in a manner to prevent misalignment or damage. The installation shall be performed by facto ry certified personnel. Installation shall be complete in all respects, including all framing and all related fastenings and anchors required for a complete installation.
