6.3 Maintenance and Inspection
CAUTION!

Before cleaning the exterior box of the voltage amplifier, turn off the power switch and
unplug the power plug. Failure to do so may result in a fire or electrical shock.

Clean the exterior box using a damp cloth that has been firmly wrung-out. Do not use
alcohols, benzene, paint thinner or other inflammable substances. If flammable substances
come into contact with an electrical component inside the voltage amplifier, this may result
in a fire or electrical shock.
6.4 Environmental Conditions
The amplifier can be used:

indoors only

at an altitude of up to 2000 m

at a temperature between: 5...35 °C

at a relative humidity between: 5...95% (non-condensing)
The recommended environmental conditions:

indoors only

at an altitude of up to 2000 m

at a temperature between: 20...22 °C

at a relative humidity between: 5...80% (non-condensing)
7 Instructions for checking the function of the system / quick start
When you open the package, please check to make sure all the necessary parts are included
(see packing list) and nothing is damaged. Check the electronics and the actuator for any
visible damage:

The top and bottom plates of the actuator (if it does not have another shape) should be
parallel each to each other and not have any scratches.

If there is any damage to the system please contact our local representative immediately!

If the packaging material is damaged please confirm this with the shipping company.

Ensure that the main voltage supplied in your country is the same as the one installed in the
system (Check the voltage label on the backside of the power supply).

The power switch should be in the off position.

Connect the power supply.

Connect the piezo actuator by using the D-SUB 15pin connector. Be sure the cables are
connected properly to the electronics.

Turn the system on by using the POWER switch on the Front panel. The green

“READY” LED indicates that the power supply is working. It is followed by a short self test.

The yellow
LED’s ”OVL” and “UDL” will blink. The green “OL/CL” LED shines permanently.
If there is an actuator plugged into the D-SUB 15pin and the amplifiers are working, the
LED's will switch off after about 3 seconds.

Switch on closed loop by pressing on the encoder knob. The OL/CL LED will shine yellow.
Turn the knob to the left until the minimum position (0 µm) is reached and switch off the
closed loop.

Now you can set the position with the
“OFFSET” encoder knob.

If the UDL/OVL-LED lights up there is an error. In this case please read the chapter on
troubleshooting. Please switch off the device.

The function check is complete.
