There is a switch on the back of the 20-040 that needs to be set to the LOCAL position. When in the LOCAL position the high voltage is set by the user but the 32-095 or 32-096 X-ray source control turns the 20-040 high voltage on and off.     Sometimes the LOCAL \/ REMOTE switch can become oxidized in which case the 20-040 high voltage may not turn on.  This post explains how to remove the LOCAL \/ REMOTE switch and hard wire the board to the LOCAL position.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?ssl=1\"><img data-recalc-dims=\"1\" decoding=\"async\" data-attachment-id=\"3748\" data-permalink=\"https:\/\/www.rbdinstruments.com\/blog\/20-040-x-ray-source-power-supply-local-remote-switch\/20-040-front-panel\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?fit=2560%2C1278&amp;ssl=1\" data-orig-size=\"2560,1278\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"20-040 front panel\" data-image-description=\"&lt;p&gt;20-040 X-ray source high voltage supply&lt;\/p&gt;\n\" data-image-caption=\"&lt;p&gt;20-040 front panel&lt;\/p&gt;\n\" data-large-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?fit=584%2C291&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/plugins\/jquery-image-lazy-loading\/images\/grey.gif?w=584&#038;ssl=1\" data-original=\"https:\/\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-1024x511.jpg\" alt=\"20-040 front panel\" class=\"lazy wp-image-3748\"\/><noscript><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"584\" height=\"291\" data-attachment-id=\"3748\" data-permalink=\"https:\/\/www.rbdinstruments.com\/blog\/20-040-x-ray-source-power-supply-local-remote-switch\/20-040-front-panel\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?fit=2560%2C1278&amp;ssl=1\" data-orig-size=\"2560,1278\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"20-040 front panel\" data-image-description=\"&lt;p&gt;20-040 X-ray source high voltage supply&lt;\/p&gt;\n\" data-image-caption=\"&lt;p&gt;20-040 front panel&lt;\/p&gt;\n\" data-large-file=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?fit=584%2C291&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel.jpg?resize=584%2C291&#038;ssl=1\" alt=\"20-040 front panel\" class=\"wp-image-3748\" srcset=\"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=1024%2C511&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=300%2C150&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=768%2C384&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=1536%2C767&amp;ssl=1 1536w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=2048%2C1023&amp;ssl=1 2048w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?resize=500%2C250&amp;ssl=1 500w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?w=1168&amp;ssl=1 1168w, https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2023\/05\/20-040-front-panel-scaled.jpg?w=1752&amp;ssl=1 1752w\" sizes=\"auto, (max-width: 584px) 100vw, 584px\" \/><\/noscript><\/a><figcaption>20-040 front panel<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Make sure that the 20-040 main power switch is OFF and then unplug all cables from the back of the 20-040 and remove the 20-040 from the electronics console.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remove the top cover (8 cross head screws).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unscrew the nut on the LOCAL \/ REMOTE switch and also unscrew the two nuts on the 15 pin connector.
