Doing a Function Test
1. Plug the power cord into the power socket.
2. Switch the electronics on.
3. Switch the electronics to open-loop mode
(
SERVO
switch in the
OFF
position).
4. Turn the
DC OFFSET
potentiometer.
5. Make sure that the displayed output volta-
ge changes.

-
tronics
Requirements
✔
The electronics are switched off.
✔
You have read and understood the user
manual for the positioner.
Tools and Accessories
▪
Positioner with compatible drive type
▪
If necessary: Suitable adapter from PI
▪
If necessary: Suitable extension cable from
PI
Connecting the Positioner
1. Plug the positioner‘s drive connector into
the electronics.
2. If necessary: Plug the positioner‘s sensor
connector into the electronics.
3. If possible: Secure the connectors against
unintentional removal.
NOTICE
Uncontrolled oscillation can damage the
positioner or your application.
X
If oscillation occurs, switch off the
servo mode or stop the positioner
immediately.
X
Check the servo control settings
respectively the settings for the
operating parameters (see the user
manual).
Requirements
✔
The electronics are switched off.
✔
There is no control signal at the
CONTROL
INPUT
sockets or it is set to 0 V.
✔
The
DC OFFSET
potentiometers are set to 0.
Starting and Operating
Operating with Analog Control Signal
Amplifier (Open-Loop Operation)
1. Switch the amplifier on.
If there is a display, the default screen
appears.
2. Command the positioner to move:
Apply a suitable input control signal to the
CONTROL INPUT
(refer to manual) or use
the
DC OFFSET
potentiometer.
Controller (Closed-Loop Operation)
1. Move the
SERVO
switch for each channel to
the OFF position (open-loop operation).
2. Switch the controller on. If there is a dis-
play, the default screen appears.
3. Move the
SERVO
switch of all channels to
the ON position (closed-loop operation).
4. Command the positioners to move:
Apply a suitable input control signal to the
CONTROL INPUT
socket (see manual) or use
the
DC OFFSET
potentiometer.
5. If the
Overflow
LED for the channel lights
up, adjust the sensor‘s zero point with the
ZERO
potentiometer until the
Overflow
LED
extinguishes.
Adjusting the sensor‘s zero point is neces-
sary if it has shifted as a result of tempera-
ture changes or mechanical load and the
positioner is prevented from covering its
full travel range.
Operating with a PC
It is possible to control via a PC if the electro-
nics are equipped with a suitable interface such
as TCP/IP, USB, RS-232 or IEEE-488.

Follow the instructions in the manual for
the electronics.
