Chapter 5 Entrance and Exit Photo-Eyes
Miscellaneous
The Photo Eyes are positioned just inside of the bay, behind any door returns. Make sure the photo eyes are placed
so the Undercarriage Wash does not spray into the beams (see example below). Also see the following large format
drawings in this section for more details.
In very short bays it may be necessary to place the Photo Eyes on the outside of the building. Refer to your site-
specific plans for more detail.
1) Place the taller, driver side, photo eye at 21” from the center of the main manifold of the undercarriage wash to the center
of the leg of the photo eye.
2) Position the shorter, passenger side, photo eye at 15” from the center of the main manifold of the undercarriage wash to
the center of the leg of the photo eye.
Note: You should have the “receiver” Photo Eye (tall stand, if floor mounted) with its back to any
direct sun light. Direct sunlight may adversely affect the performance.
