Mirrors not fixed centrically can damage the
positioner.
X
For dynamic applications, mount the mirror
as near to the center as possible to prevent
uneven loading of the flexures and, as a
whole, the positioner.
X
Recommended eccentricity: 0.25 mm
Operating voltages that are excessively high or
incorrectly connected can cause damage to the
positioner.
X
Observe the operating voltage range of the
positioner (see manual).
X
Observe the correct pin assignment.
Excessively fast discharging can destroy the
piezo actuators of the positioner.
X
Discharge the positioner only according to
the instructions in the manual.
Startup
If a protective earth conductor is not properly
connected, touching the positioner in the case
of malfunction can result in minor injuries from
electric shock.
X
Only operate the positioner with a properly
connected protective earth conductor.
X
Do
not
remove the protective earth con-
ductor from the positioner during opera-
tion.
X
Observe the applicable standards for atta-
ching the protective earth conductor .
X
If there is any vibration in your application,
secure the screw connection for the protec-
tive earth conductor in a suitable manner
(e.g., with liquid adhesive) to prevent it
from unscrewing by itself.
The surface of the positioner and the sur-
rounding area can heat up during operation.
Touching the positioner and surrounding parts
can result in minor injuries from burning. The
heat produced during operation can affect your
application.
X
If possible: Cool the positioner sufficiently.
X
If necessary: Install touch protection.
X
If sufficient cooling and protection against
contact are not possible: Mark the danger
zone in accordance with the legal regula-
tions.
X
Install the positioner so that your applicati-
on is not affected by the dissipating heat.
Moisture, liquids, and electrically conductive
materials (e.g., metal dust) that penetrates
the positioner, as well as surroundings with
increased conductivity, can destroy the piezo
actuators of the positioner.
X
Only operate the positioner within the per-
missible ambient conditions (see manual).
X
Do
not
operate a vacuum-compatible posi-
tioner during evacuation.
Uncontrolled oscillation can damage your appli-
cation or the positioner.
X
If oscillation occurs, switch off the servo
mode or stop the positioner immediately.
X
Check the settings of the servo-control
parameters (see the manual for the elec-
tronics).
Operation
Continuously high voltages can reduce the
lifetime of the positioner.
X
Keep the maximum operating voltage as
low as possible during operation.
X
Discharge the positioner appropriately
when it is not in use.
