6 Start-Up and Operation
NOTICE
Destruction of the piezo actuator by electric flashovers!
The use of the P­2x5 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 such as
metal dust. In addition, electric flashovers can also occur in certain air pressure
ranges due to the increased conductivity of the air.

Avoid operating the P­2x5 in environments that can increase the electric
conductivity.

Only operate the P­2x5 within the permissible ambient conditions and
classifications (p. 50).

For operation in vacuum below 0.1 hPa:
Do not operate the P­2x5 during evacuation.
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 tensile/compressive stress capacity according to
the specifications (p. 47).

Observe the notes in "Determining the Operating Parameters" (p. 34).
NOTICE
Destruction of the piezo actuator by operating frequencies that are too high!
An operating frequency that is too high can destroy the piezo actuator.

Select the operating frequency so that the following conditions are met:
−
−
32
The operating frequency is maximally one third of the resonant frequency
(resonant frequency of the unloaded piezo actuator see "Data Table" (p. 47),
resonant frequency of the loaded piezo actuator see "Calculating the
Maximum Operating Frequency of the Loaded Piezo Actuator" (p. 36)).
The dynamic forces that occur during operation do not exceed the maximum
tensile/compressive stress capacity of the piezo actuator (see "Calculating
Forces that Occur During Dynamic Operation" (p. 37)).
