As a result, the operator placed a service call to Nyx Hemera Technologies&#8217; technical department at 1:21 p.m. using Microsoft Teams. Using remote access granted by the operator, the Nyx Hemera Technologies team took remote control of the TLACS lighting SCADA. During this session, the technical team confirmed that there were 14 luminaires in alarm in two specific areas of the tunnel. Using electrical parameters provided by the LPC (Local Product Controller), which is installed in the luminaire and uses powerline communication to communicate with TLACS&#8217; main controller, the LCC, the Nyx team was able to remotely investigate and discover that a voltage drop below the luminaire&#8217;s driver threshold was causing the flickering. The call ended at 2:45 pm. Once this information was relayed to the on-site team, the tunnel was closed for 45 minutes to resolve the problem by replacing a power terminal block located in one of the electrical distribution junction boxes. Lighting and traffic then returned to normal.<\/p><p><em>A Friday 13th that ends well!<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-f07da3c\" data-id=\"f07da3c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-2e4ef26 elementor-widget elementor-widget-image\" data-id=\"2e4ef26\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"708\" height=\"512\" src=\"https:\/\/www.nyx-hemera.com\/wp-content\/uploads\/2025\/08\/TLACS-1-hour-EN.png\" class=\"attachment-large size-large wp-image-18144\" alt=\"\" srcset=\"https:\/\/www.nyx-hemera.com\/wp-content\/uploads\/2025\/08\/TLACS-1-hour-EN.png 708w, https:\/\/www.nyx-hemera.com\/wp-content\/uploads\/2025\/08\/TLACS-1-hour-EN-300x217.png 300w\" sizes=\"(max-width: 708px) 100vw, 708px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-981c4c9 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"981c4c9\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-40f8ee3\" data-id=\"40f8ee3\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3546de8 elementor-widget elementor-widget-heading\" data-id=\"3546de8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Teamwork is key<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-264c00e elementor-widget elementor-widget-text-editor\" data-id=\"264c00e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>On August 13, 2021, a tunnel operator using Nyx Hemera Technologies&#8217; Powerline Lighting Control System (TLACS) contacted Nyx&#8217;s technical support team with a problematic situation that appeared to be related to the lighting control system installed in their tunnel.
