Thelongerthelighttransmitter,thegreaterthegapwillbe.Themaxi-
mummountingdistancecanbecalculatedasfollows:

Ifthecameralooksdownonthewebfromabove,itshouldbemount-
edsothatthearrowonthecameraoperatingcontrolspointsinthe
directionofwebtravel.Ifthecameralooksuptothewebfrombelow,
thearrowshouldpointintheoppositedirectiontothatofwebtravel.
OncamerasystemsdesignedbyE+L,themodulereferencemust
alsobechecked(e.g.B2).Theblockdiagramspeciesexactly
whichcamerashouldbemountedonwhichsideoftheweb,seen
fromthedirectionofwebtravel.

TwodifferentE+Lsupportsareavailableformountingthecamera,
seeattacheddrawing.
 We recommend you pin the supports once the camera has
been positioned (7.1 commissioning).
Howthelighttransmitterismounteddependsonthescanningpro-
cessimplemented.
