Actions to take to avoid the situation. NOTICE Dangerous situation If not avoided, the dangerous situation will result in damage to the equipment. Actions to take to avoid the situation. INFORMATION Information for easier handling, tricks, tips, etc. Figures For better understandability, the colors, proportions, and degree of detail in illustrations can deviate from the actual circumstances. Photographic illustrations may also differ and must not be seen as guaranteed properties. Safety Intended Use The P-721 Z drive is a laboratory device as defined by DIN EN 61010-1. It is intended to be used in interior spaces and in an environment which is free of dirt, oil and lubricants. Based on its design and realization, the P-721 is intended for positioning and shifting microscope objectives in one axis. The P-721 can be mounted horizontally or vertically. The specifications refer to a vertically mounted P-721. The intended use of the P-721 is only possible in a completely assembled and connected state. The P-721 must be operated with a suitable controller that is available from PI. The controller is not included in the scope of delivery of the P-721. Physik Instrumente (PI ) GmbH & Co. KG, Auf der Roemerstr. 1, 76228 Karlsruhe/Germany Phone +49 721 4846-0, Fax +49 721 4846-1019, Email info@pi.ws, www.pi.ws Page 4 / 22 2017-03-29 P721T0007, valid for P-721 Safety Precautions CAUTION Dangerous voltage and residual charge on piezo actuators! The P-721 is driven by piezo actuators. Temperature changes and compressive stresses can induce charges in piezo actuators. After being disconnected from the electronics, piezo actuators can also stay charged for several hours. Touching or short-circuiting the contacts in the connector of the P-721 can lead to minor injuries. In addition, the piezo actuators can be destroyed by an abrupt contraction. Do not open the P-721. Discharge the piezo actuators before installation: Connect the Z drive to the switched-off PI controller for 10 seconds. Do not pull out the connector from the electronics during operation. For P-721 with sub-D connector: Touching the contacts in the connector can lead to an electric shock (max. 120 V DC) and minor injuries. Do not touch the contacts in the connector. Secure the connector of the piezo actuator with screws against being pulled out of the controller. CAUTION Risk of electric shock if the protective earth conductor is not connected! If a protective earth conductor is not or not properly connected, dangerous touch voltages can occur and there is a risk of electric shock. In the case of malfunction or failure of the system, touching the P-721 can result in minor injuries. Connect the P-721 to a protective earth conductor before start-up. Do not remove the protective earth conductor during operation. Use electrically conductive materials (e.g., screws and flat washers) for mounting the protective earth conductor. Make sure that the contact resistance is <0.1 Ω at 25 A at all connection points relevant for mounting the protective earth conductor. If the protective earth conductor has to be temporarily removed (e.g., for modifications), reconnect the P-721 to the protective earth conductor before starting it up again. NOTICE Unsuitable cables! Unsuitable cables can damage the electronics. Only use cables from PI for connecting the P-721 to the electronics. Physik Instrumente (PI ) GmbH & Co.

See the P721T0002 technical note (p. 7) for details. Start-Up and Operation General Notes on Start-Up and Operation NOTICE Destruction of the piezo actuator by electric flashovers! The use of the P-721 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 P-721 in environments that can increase the electric conductivity. Only operate the P-721 within the permissible ambient conditions and classifications (p. 21). NOTICE Destruction of the piezo actuator by continuously high voltage! The constant application of high voltage to piezo actuators can lead to leakage currents and flashovers that destroy the ceramic. If the P-721 is not used, but the controller is to remain switched on to ensure temperature stability: Set the piezo voltage to 0 V on the controller. Physik Instrumente (PI ) GmbH & Co. KG, Auf der Roemerstr. 1, 76228 Karlsruhe/Germany Phone +49 721 4846-0, Fax +49 721 4846-1019, Email info@pi.ws, www.pi.ws Page 12 / 22 2017-03-29 P721T0007, valid for P-721 NOTICE Uncontrolled oscillation! Oscillations can cause irreparable damage to the P-721. Oscillations are indicated by a humming and can result from the following causes: The load and/or dynamics of operation differ too much from the calibration settings. The P-721 is operated near its resonant frequency. If you notice oscillations, stop the P-721 immediately. INFORMATION Systems are calibrated at the factory to achieve optimum performance. Replacing the system components will cause a loss in performance when Z drives without ID chip are used, or whose ID chip does not contain any calibration data, or when Z drives with LEMO connectors or analog controllers are used. Only P-721.CDQ and P-721.CDA Z drives are equipped with an ID chip. Note the assignment of the Z drive axis to the controller channel, which is given by the calibration label of the piezo servo controller. For systems without ID chip: If the piezo servo controller or the Z drive has to be replaced, recalibrate the axis displacement (see controller manual) or contact our customer service department (p. 14). Starting Up and Operating the P-721 Requirements You have read and understood the safety precautions (p. 4). You have read and understood the general notes on start-up and operation (p. 11). Starting up and operating the P-721 Follow the instructions in the manual of the piezo controller used for start-up and operation of the P-721. Discharging the P-721 The P-721 must be discharged before demounting. Demounting is necessary e.g., before cleaning or transporting the P-721 as well as for modifications.

Switch off the servo mode on the controller. 2. Set the piezo voltage to 0 V on the controller. In open-loop operation: Set the piezo voltage to 0 V on the controller. Discharging a P-721 that is not connected to the controller Connect the P-721 to the switched-off PI controller for 10 seconds. Maintenance NOTICE Misalignment from loosening screws on the base body! The P-721 is maintenance-free and precisely aligned. Only loosen screws according to the instructions in this manual. Do not open the P-721. Cleaning the P-721 Requirements You have discharged the piezo actuators of the P-721. You have disconnected the P-721 from the controller. Cleaning the P-721 Clean the surface of the P-721 with a cloth that is lightly dampened with a mild cleanser or disinfectant (e.g., ethanol or isopropyl alcohol). Do not do any ultrasonic cleaning.
