LD Series Operation Manual
CROSSHEAD MOVEMENT LIMITS
The LD Series is fitted with two mechanically activated limit stops. These can be used as extra protection to stop load cells, grips or fixtures coming into con-
tact, or to back up the tests upper and lower limits. Activating a limit stop will automatically stop the machine.

OPTIONAL SPLINTER SHIELD
A transparent splinter shield is available as an option to enclose the test sample. A shield should be
used if any danger of samples shattering during the test exists. The shield has an electronic interlock,
which requires the hinged shield to be closed before the test can start.
SAFETY JOG
The LD Series has a built in safety feature to provide protection while jogging the machine. If the
machine measures an unexpected resistance while jogging, it will automatically stop.
Note:
The resistance level is selectable in the Nexygen
Plus
4 software.
