• Iftheproblemfollowstheconnectionchange,thelinear
encoder may be in error.
IftheReadoutisatfault,referto“Whattodo”toarrangeforthe
parts necessary to repair your system. If a linear encoder appears
tobeatfault,proceedwith“CheckingtheLinearEncoders”.
Checking the Linear Encoders
Problemsonasingleaxisareusuallyassociatedwiththelinear
encoder or its installation. Difficulties can be caused by improper
installation,looseormisalignedbracketry,oradamagedor
inoperable encoder.
Followthesestepstodeterminethecauseofyoursystem
difficulties:
• Conrmthatyourbracketryandinstallationdoesnotinterfere
withothermachinestructuresthroughtheentirelengthofthe
linearencodertravel.
• Checkforloosefasteners.Ifyoundloosefasteners,rst
confirm that the linear encoder is installed to the tolerances
specified and then retighten the fasteners as required.
• Conrmthatthelinearencoderisinstalledtotherequired
tolerances by checking the alignment tolerances specified
onPage4.Iftheinstallationdoesnotmeetthetolerances,
reinstalltheencoderaccordingtothe“InstallationProcedure”.
• PerformaRepeatabilityTestasdescribedonPage13.Ifthe
linearencoderisinstalledtotherequiredtolerances,the
bracketryandencoderhavebeencheckedforinterferencesand
loosefasteners,andtheencoderfailstherepeatabilitytest,the
encoder is likely at fault.
Do not attempt to repair the reading head or scale assembly. The
SENC150iseldserviceablebyassemblyreplacementonly.
Attemptstorepairtheencodercanpermanentlydamageitand
