PZ272E
P-545 Nanopositioners
The P-545 is driven by piezo actuators. Temperature changes and compressive stress can induce
charges in piezo actuators. Piezo actuators can remain charged for several hours after
disconnecting the electronics. Touching or short-circuiting the contacts in the P-545's connector
can lead to minor injuries from electric shock. The piezo actuators can be destroyed by an
abrupt contraction.
Do
not
open the P-545.
Discharge the positioner's piezo actuators before installing:
Connect the positioner to the switched-off PI controller equipped with an internal
discharge resistor.
Do
not
pull the connector out of the controller during operation.
Do
not
touch the contacts in the connector.
Use screws to secure the positioner's connectors against being pulled out of the
controller.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-545 in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-545 can result in minor injuries from electric shock.
Connect the P-545 to a protective earth conductor (p. 18) before starting.
Do
not
remove the protective earth conductor during operation.
If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-545 to the protective earth conductor before restarting.
Mechanical forces can damage or misalign the P-545.
Avoid impacts that affect the P-545.
Do
not
drop the P-545.
Do
not
exceed the maximum permissible stress and load capacities according to the
specifications (p. 37).
Do
not
touch any sensitive parts (e.g., platform) when handling the P-545.
The P-545 is maintenance-free and achieves its positioning accuracy as a result of the optimum
alignment of mechanical components and piezo actuators.
Do
not
open the P-545.
