If you experience difficulties with your installation, do the
following to determine the problem.
Checking the Readout
Difficulties on more than one axis are usually associated with
the readout. Follow these steps to determine if your
difficulties are associated with the readout:
• Ensure that the linear encoder connectors are correctly
seated.
• Swap linear encoder cables at the readout to see if the
problem is still shown in the same display.
• If the problem remains in the same display, the readout
may be in error. To determine if that is the problem, repeat
above steps with both encoders, but with only one encoder
connected at a time. This should allow you to determine if
the problem is with the readout or the encoder.
• 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:
• Confirm 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 find loose fasteners, first
confirm that the linear encoder is installed to the
tolerances specified and then retighten the fasteners as
required.
• Confirm that the linear encoder is installed to the specified
alignment tolerances. If the installation does not meet the
tolerances, reinstall the encoder according to the
“Installation Procedure”.
• Do not attempt to repair the reading head or scale
assembly. The ENC 250 is field serviceable by assembly
replacement only. Attempts to repair the encoder can
permanently damage it and void the warranty.
What to do
If an ACU-RITE linear encoder or readout is found to be at
fault, please contact your Authorized Distributor for
instructions prior to removing the encoders or readout.
