6. Monitorthespeedoftheblowermotorduringthestandardizationprocess.After
standardizationisactivated,therealtimespeedcanbereadusingthefollowingmenupath:

Params&Display>VSDModule>Speed>AbsoluteSpeed

 Duringstandardization,theabsolute speedshouldriseuptoapeakvalueandholdsteady
atthatvalueforafewseconds.Then,thevalueshoulddropbackdowntozero(ornear
zero).

 Thepeakvaluethatisseenshouldberecordedasthestandardizedspeed.Ifthisdoesn’t
happen,it’slikelythatthere’saproblemwiththeVSDorthespeedsensor.
