OpenLayers request tiles out of range

Question

OpenLayers map is requesting tiles out of range and all the map is pink. If I inspect single tile, the address is next:

/Tiles/15/16384/16384.png

But the folder with generated tiles does not contain such values: The range is only: /Tiles/15/16099 - /Tiles/15/16119

The tiles are generated by Maperitive. Is it a Maperative problem or I should set additional options to OpenLayers.Map?

map = new OpenLayers.Map("demoMap");
var cLayer2 = new OpenLayers.Layer.OSM("New Layer", 
"http://localhost:15157/Map/Tiles/${z}/${x}/${y}.png", { numZoomLevels: 19 });
map.addLayer(cLayer2);
map.zoomToMaxExtent();

Answer 1

The problem was resolved. The reason was in differences between Maperitive and OpenLayers coordinates. lon lat point in maperitive is not the same point on the map, that's why the map was requesting out of range tiles.

I generated my tiles with zoom levels 2-18 and they were displayed on the map.
