7.3.3 amplifier without integrated feedback controller

Any system delivered as open loop mode can not be modified to closed loop later on.
Any closed loop system can be easily calibrated to a different closed loop piezo afterwards.
This is only possible at piezosystem jena and will cause additional effort and costs.
Please contact our sales team for more information.

7.4 initiation

Please follow all safety instruction given in chapter 6 before using the amplifier.

7.4.1 main supply voltage

The amplifier NV40/3, NV40/3CLE, NV120/1 and NV120/1CLE require a main supply voltage
of 24VDC. A power supply unit suitable for voltages from 100 up to 240Volt AC is included in
the shipment. The socket for the main supply voltage is located on the back panel of the
amplifier.

7.4.2 connecting piezo actuator

Piezo electrical actuators are connected to the amplifier unit by using the D-SUB connector
on the back panel. Please make sure that the amplifier is switched off when connecting /
disconnecting the PZT to the amplifier. Please fasten the screws of the D-SUB connector
and guarantee a firm connection. After switching on the initialization procedure follows.
(please see chapter 7.1) Then the display shows the details of the used PZT.
If the display shows the information "NOT CONNECTED" please check the connection
between PZT connector and amplifier again. Please note: during initialization procedure the
operation of the unit is disabled.
