SENC 125 T/E Trouble Shooting
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:
• Insure 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 is in
error.
• 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 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 125 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 .
