Trouble Shooting SENC 50
If you experience difficulties with your installation, there are
methods to analyze the difficulty. Operating difficulties can be
caused by either the linear encoders or 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.
• Follow this procedure for any intermittent problem
experienced.
If the readout is at fault, refer to “

the parts necessary to repair your system. If the linear encoders
appear to be the cause, perform the next step.

Checking the Linear Encoders
Linear encoder difficulties can be caused by improper
installation, loose or misaligned bracketry, or a damaged / failed
linear 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 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

“Key Points”. If the installation does not meet the
tolerances, reinstall the linear encoder according to the
procedures in “

Installation”.
• Perform a Repeatability Test as described on Page 10,

Checking Your Installation”. If the linear encoder is
installed to the required tolerances, the bracketry and linear
encoder have been checked for interferences and loose
fasteners, and the linear encoder fails the repeatability test,
the linear encoder is likely at fault.
Do not attempt to repair the linear encoder. The units are only
serviceable by assembly replacement. Attempted repair can
permanently damage the unit and void the warranty.

If an Acu-Rite Companies Inc. linear encoder or readout is found
to be at fault, prior to removing the linear encoders or readout
contact your Authorized Distributor or OEM/OEI for repair
instructions.
