(l) Event logs
839
733.03
(5) Furnish a Monitor that is capable of storing events into
memory. Typical events are fault events, AC line events, reset events, etc. When
a fault event is stored into memory, the Monitor will store the fault condition
(type), channel status, date, time, temperature, and line voltage. Ensure that the
log history stores a minimum of 100 total events.
h. Diode Matrix and Software. Furnish a Monitor that loads the
diode matrix programming into a non-volatile memory device. When the diode
matrix is loaded into memory, the memory will regularly compare with diode card
and fault condition will occur if memory does not match the diode card matrix.
Furnish 332 cabinet according to the Department’s Qualified Products List
(QPL).
D. Type 334.
1. General. Furnish Model 334C cabinets that meet the specifications
“Traffic Signal Control Equipment Specifications” and “Transportation Electrical
Equipment Specifications”, California Department of Transportation. Ensure that
the manufacturer of the cabinets is listed on the CalTrans QPL at the time of the
project award.
2. Cabinets. Furnish cabinets that are constructed of aluminum and are
supplied unpainted. An anodic coating is not required. Supply galvanized anchor
bolts with nuts and washers with each cabinet. Furnish 3/4-inch (19 mm) diameter
by 16 inches (0.4 m) minimum length anchor bolts with an “L” bend on the
unthreaded end.
3. Terminals and Wiring. Ensure that the vehicle detector field wiring
inputs connect to side mounted terminal blocks. Install terminal blocks and
associated wiring to the input file. Label the field wiring terminals of the side
mounted terminal block by a permanent screening process to identify the input
panel (I), the input file slot number (1 through 14) and the channel terminal (D, E,
J, or K). An example is “I4-E”. Ensure that all terminals on these detector blocks
are accessible without removing equipment from the EIA mounting rack.
4. Accessories.
a. Fully equip the cabinets with two channel loop detector sensors,
transfer relay, power supply, conflict monitor and switchpacks. When ramp meter
warning signs with flashers are used, include a NEMA or Caltrans type flasher
wired for control from the controller.
b. Furnish a police panel in each cabinet with the Caltrans required
switches. No pushbutton with cord is provided.
c. Furnish an aluminum shelf with integral storage compartment in
the rack below the controller. Ensure that the storage compartment has telescoping
drawer guides for full extension. Ensure that the compartment top has a non-slip
plastic laminate attached.
