PL0xx/PDxxx Piezo Actuator
CAUTION
Burning from hot surface!
The surface of the PL0xx/PDxxx and the surrounding area can heat up during operation.
Touching the PL0xx/PDxxx and surrounding parts can result in minor injuries from burning.
Cool the PL0xx/PDxxx so that the temperature of its surface and surrounding parts does
not
exceed 65 °C. Do
not
use liquids for cooling. If liquid cooling is to be used, contact our
customer service department (p. 47).
If sufficient cooling is not possible: Make sure that the hot PL0xx/PDxxx and its surrounding
parts
cannot
be touched.
If sufficient cooling and protection against contact are not possible: Mark the danger zone
in accordance with the legal regulations.
NOTICE
Destruction of the piezo actuator due to electric flashovers!
Using the PL0xx/PDxxx in environments that increase the electrical conductivity can lead to the
destruction of the piezo actuator by electric flashovers. Electric flashovers can be caused by
moisture, high humidity, liquids, and conductive materials (e.g., metal dust).
Avoid operating the PL0xx/PDxxx in environments that can increase the electrical
conductivity.
Only operate the PL0xx/PDxxx within the permissible ambient conditions and
classifications (p. 53).
Prevent the piezo actuator from coming into contact with liquids. If liquid cooling is to be
used, contact our customer service department (p. 47).
Protect the piezo actuator against moisture by means of hermetic sealing or the supply of
dry air.
If the PL0xx/PDxxx is to be operated in a special gas atmosphere, contact our customer
service department (p. 47).
NOTICE
Destruction of the piezo actuator by dynamic forces!
During dynamic operation, dynamic forces can occur that cancel the preload of the piezo
actuator. Operation without a preload can destroy the actuator.
Do
not
exceed the maximum compressive/tensile stress capacity (p. 52).
Observe the notes in "Determining the Operating Parameters" (p. 35).
