CAUTION
Do not make mechanical, or soware adjustments to system components unless you know
exactly how the adjustment will aect system operaon. In many cases a slight adjustment can
throw the system out of calibraon and cause divergence between the command and feedback.
Consult an experience user when in doubt about any adjustment procedure.

CAUTION
If the control feedback signal is interrupted during operaon, the controller senses an error.
The actuator will aempt to correct the error by stroking at maximum force unl it reaches
an internal or external mechanical limit. The external mechanical limit may be any type of
obstrucon that is in the path of a stroking actuator (such as tools, specimens, or hands). Be
aware that the full force of the actuator will be applied to an external mechanical limit or
obstrucon. The only eecve way to minimize the stac force capability of a system is to reduce
the system hydraulic/pneumac pressure. The error detectors in the controller minimize the
potenal for device under test or equipment damage caused by loss of feedback or larger than
normal feedback errors.

CAUTION
Due to servo valve silng, an actuator can develop random instability or errac operaon
at unusually low hydraulic pressures, especially if the system uses large servo valves or the
hydraulic uid is dirty.
