DTS-10 Sequence of Operation:
With an empty dock, the DTS-10 lights are green outside and the red inside. Once a truck driver has chocked the trailer's wheels the driver presses the outside "CHOCKED" button, which flips the outside light red and the inside light green. If the truck driver fails to press the outside button, the dock attendant can press the "CHOCKED" button at the inside control panel, if it has been affirmed that the trailer wheels are chocked. (OSHA Standard 1910.178 sections (k)(1) and (m)(7) requires that wheel chocks be placed under the rear wheels of a truck.) Once the trailer has been loaded/unloaded, the dock attendant presses the "DEPART" button to indicate that it is okay for the truck driver to remove the chocks from in front of the trailer wheels and pull away from the dock. Pressing the "DEPART" button causes the lights to turn green outside and red inside.
