If you experience difficulties with your installation, there are methods
to analyze the problem. Operating difficulties can be caused by
either a linear encoder or a readout. Problems on a single axis are
usually associated with the linear encoder or its installation.
Difficulties on more than one axis are usually associated with the
readout.
Checking the Readout
Follow the steps below 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
Difficulties can be caused by improper installation, loose or
misaligned bracketry, or a damaged or inoperable encoder.
Follow the steps below 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 11. 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
ENC 150 is field serviceable by assembly replacement only.
Attempted repair can permanently damage the unit and void the
warranty.
What to do
If an ACU-RITE linear encoder or readout is found to be at fault,
prior to removing the encoders or readout contact your Authorized
ACU-RITE Distributor or OEM/OEI for repair instructions.
