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
