handling

The actuator is connected to the 30DVxxx using the "PIEZO" plug. The encoder knob is used to
adjust a static output voltage or position, depending on the operation mode (Offset). The
"ANALOG" plug offers analog interface to control the amplifier using a voltage between 0 and +10
V. So, arbitrary and scan functions are possible. Please remove any analog input voltage from the
amplifier before you turn the system on or off to avoid damage. To control the amplifier via RS232
please connect the computer and the amplifier with the provided serial cable. Then start the
terminal program (see chapter communication).
After power-on, the LED's "UDL", and "OVL" blink. The amplifier makes its power-on self test for
2 seconds. During this procedure all necessary parameters are transferred from the actuators
ID-chip to the amplifier. When the "UDL" and "OVL" LEDs stop blinking, the amplifier has initialized
successfully. Amplifiers without an attached actuator cannot complete this sequence.
When the system starts up and no external voltage is applied to the MOD input, the actuator is in
the most negative position (pos.1) of its deviation (pos.1 to pos.4, see sketch 2). By pressing the
knob in, the operation mode changes to closed loop and the "OL/CL" LED changes to yellow.
When closed loop is turned on, the actuator moves to the start position of the closed loop range
(pos.2). Turning the encoder to the right will increase the deviation until it reaches its maximum
position (pos.3). This range will vary depending on your type of actuator.

The yellow "OVL" LED shows an overload, the yellow "UDL" LED shows an underload. Please try
to avoid this. When an external analog voltage is applied, try to decrease or remove it. If the LED's
still light up, check the connection between the amplifier and the actuator. Additionally, a
mechanical blocking or overload of the actuator can prevent actuators from reaching their position.
If none of the described troubleshooting has worked, turn off the system and contact our support
team. Please do not continue working after your actuator has been damaged.
The values of calibration are valid only for a specified assembly configuration. Any change
in the assembly configuration can cause the modes OVL or UDL. Please provide us with
your assembly configuration in advance.
