We will also verify proper operation of all equipment displays and cabinet/controller indicator lamps. Deficiencies that pose a safety concern will be corrected immediately. o Semi-annually verify that controller software/firmware is up to date. Following the visual inspection, your Yunex Traffic technician will examine the functionality of the controller in relation to traffic at the intersection and confirm all phase and coordination timing is programmed correctly and is current based on the timing sheet located in the controller cabinet. In addition to monitoring phase actuation from vehicle/traffic, they will also confirm proper intersection cycling by manually placing vehicle and pedestrian calls on each phase through the cabinet test switches or the controller keypad to verify controller servicing of each phase. Yunex Traffic technicians will ensure your controller's date and time is correct and we will adjust all controller clocks within 48 hours of time changes related to Daylight Savings Time. This also includes confirming the correct date and time in all Conflict Monitor Units and Malfunction Management Units (CMU/MMU) during each visit. Your Yunex Traffic technician will check the controller log buffers and investigate any faults that may have surfaced since the last maintenance visit. CMU's/MMU's can be tested annually or as requested. Technicians will be ATSI CMU/MMU Test Equipment Certified. Individual test results will meet the city's documentation requirements and be available in each controller cabinet and an electronic file (USB) will be delivered to the city within 30 days after completing the testing. This test will also be documented on the routine maintenance log located in the controller cabinet. If requested, the cost for annual CMU/MMU testing will be billed on a time/material basis. The technician will confirm all detector loop cables are correctly identified, connected to the correct vehicle detector field terminals, and that a call is placed on the correct detector input, and that the input places a call on the correct controller phase. We will adjust or re- tune detector amplifiers and correct substandard splices, as necessary. Loops requiring re-seal or replacement will be documented and reported to the city immediately. _ If the intersection is equipped with video/radar detection our technician will verify that detection zones are properly structured. They will also verify proper camera operation by monitoring the vehicle call on the video processor unit and confirm that the calls are registering in the controller and actuating the correct phase in the controller. The technician will verify that detection system software has been properly updated. Video Detection lens cleaning is included with Our technicians are Quarterly Routine Maintenance of Video Detection Systems. extremely knowledgeable If equipped, your Yunex Traffic technician will confirm operation with the installation, of all preemption devices (i.e., railroad, emergency vehicle handling, and testing of preemption (EVP),fire station preemption, etc.).
