PZ265E
PL0xx/PDxxx Piezo Actuator
NOTICE
Destruction of the piezo actuator due to rapid discharging!
If the piezo actuator is not connected to the electronics, it must be short-circuited in order to
prevent the piezo actuator from becoming charged during temperature changes and
compressive stresses. Unsuitable short-circuiting leads to an abrupt contraction of the piezo
actuator due to excessively fast discharging. Abrupt contraction can destroy the piezo actuator.
As soon as you have removed the piezo actuator from the conductive original packaging,
short-circuit it as follows:
−
Models with stranded wires: Twist the stranded wires of the piezo actuator with each
other.
−
Models without stranded wires: Affix a suitable, conductive aid on the piezo actuator
that does not leave any scratches on the surface of the piezo actuator (e.g., conductive
rubber).
Only disconnect the short-circuit connection of the piezo actuator if this is necessary for
installation or operation.
If the piezo actuator is not short-circuited:
−
Ensure adequate protection against touching live parts.
−
Discharge the piezo actuator in a suitable way before short-circuiting again (p. 40).
NOTICE
Destruction of the piezo actuator due to excessively high loads!
Excessive loads can destroy the PL0xx/PDxxx.
Do
not
exceed the maximum compressive/tensile stress capacity (p. 52).
NOTICE
Damage to the piezo actuator due to excessive preloading!
Excessive preloading can mechanically depolarize the piezo actuator. Depolarization damages
the piezo actuator.
Only apply preloads that are just as high as necessary.
Do
not
exceed the maximum preload (p. 52).
