836.1G (threaded bolt marked with ).
3. Connect the protective earth conductor:
a) Push the cable lug of the protective earth conductor onto the threaded bolt.
b) Screw the nut onto the threaded bolt. In this way, the cable lug attached to the
protective earth conductor is wedged between the lock washer and the nut.
c) Tighten the nut with at least three turns and a torque of 1.2 Nm to 1.5 Nm.
5.3 Connecting the Power Supply to the E-836.1G
Requirements
The power cord is not connected to the power socket.
Tools and accessories
24 V wide input range power supply included (for line voltages between 100 and 240
VAC at 50 or 60 Hz)
Alternative: Sufficiently rated power supply
Power cord included
Alternative: Sufficiently sized power cord
Connecting the power supply to the E-836.1G
Connect the power supply to the E-836.1G's 24 VDC connector.
5.4 Connecting the Positioner
Prerequisites
When a signal source is connected to the Control In BNC socket: The signal source is
switched off or its output is 0 V.
The DC Offset potentiometer is turned fully counterclockwise.
Tools and accessories
Positioner with the following characteristics:
−Drive: Piezo actuator(s)

5 Installing
E-836.1G Piezo Amplifier PZ250E Version: 1.1.0 13
−Operating voltage range: -30 to 130 V
−Voltage connection: Via LEMO connector
Connecting the positioner
Connect the voltage connection of the positioner to the PZT -30 to 130 V LEMO socket
of the E-836.1G.
5.5 Connecting the Control Input Voltage
INFORMATION
The control signal for the output piezo voltage is the sum of the following signals:
Control input voltage at the Control In BNC socket
Offset that is set with the DC Offset potentiometer
The control signal should always be within the range of –2 to +12 V. The range can be
expanded to –3 to +13 V. However, this can shorten the lifetime of the piezo actuator in the
positioner (p. 33).
Prerequisites
The signal source for the control input voltage is switched off or its output is 0 V.
The DC Offset potentiometer is turned fully counterclockwise.
Tools and accessories
Signal source for the control input voltage. The control input voltage can also be a
computer-generated analog signal (e. g. from a data acquisition board). You can use the
PI LabVIEW analog drivers to generate the analog signal (see E500T0011 Technical Note
and the PZ181E manual).
Connecting the control input voltage
Connect the signal source to the Control In BNC socket.


6 Startup
E-836.1G Piezo Amplifier PZ250E Version: 1.1.0 15
6.1 General Notes on Startup
DANGER
Risk of electric shock if the protective earth conductor is not connected!
If the protective earth conductor is not or not properly connected, dangerous touch voltages
can occur on the E-836.1G in the event of a malfunction or failure of the system. If there are
touch voltages, touching the E-836.1G can result in serious injury or death from electric shock.
Connect the E-836.1G to a protective earth conductor (p. 11) 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 E-836.1G to the protective earth conductor before
restarting.
NOTICE
Reduced lifetime of the piezo ceramic due to continuous high voltage!
Applying a high static voltage to piezo actuators continuously reduces the lifetime of the piezo
ceramic.
If the E-836.1G is not being used but should remain switched on:
Set the control signal (sum of Control In and DC Offset) to 0 V.
INFORMATION
The output piezo voltage contains the switching frequency of the internal DC/DC transducer of
the E-836.1G (600 kHz). This frequency has no effect on the motion of the positioner, however.
For this reason, the measurement of the piezo voltage (e.g. with a digital oscilloscope) is not
suitable for determining the motion resolution of the positioner.
Measure the motion of the positioner directly, e.g. with optical methods or high-resolution
sensors.
INFORMATION
When it is switched off, the E-836.1G generates a voltage spike at the output for the piezo
voltage. A connected positioner will execute a corresponding motion, which can be noticeable
as a clicking sound. This behavior is unproblematic and does
not
affect the positioner.
