Hardware settings

Hardware write protection
If write protection is active, the device parameterization cannot
be changed.
Activating and sealing the write protection switch WP (Figure 20,
7
) protects the device against tampering.
Number Function
ON Write protection active
OFF Write protection deactivated
Potential switch
The potentials switch INT
reference potential either to the system or the protective
ground.
Number Function / setting recommendation
Reference potential on system potential
Conventional control with analog set point without external
electrical isolation
Reference potential on ground potential
Conventional control with analog set point and with external
electrical isolation
Reference potential on ground potential

Basic Setup

Setting the end positions 0 % / 100 %
Note
Once commissioning is complete, set the write protection
switch to 'ON'.
1. Switch the electronic unit to the 'Adjustment' operating
mode. Press and hold down both travel buttons (Figure 20,
j
pos. ) for approx. 5 seconds, until both LEDs (Figure 20,
2 6
pos. and ) flash in synch at approx. 4 Hz.
(Figure 20, 9
) connects the
Defining the initial position (0 % or 100 %)
2. Use one of the travel buttons to move to the desired
position.
3. Press the Accept button to accept the position (Figure 20,
3 5
pos. or ); if successful, the corresponding LED flashes
at a rate of 1 Hz. The other LED will continue to flash at
approx. 4 Hz.
Defining the second position (0 % or 100 %)
4. Use one of the travel buttons to move to the second
position.
5. To accept the position, press the Accept button. If
successful, both LEDs will flash at a rate of approx. 1 Hz.
Saving the settings
6. Press both Accept buttons to accept the settings. The LEDs
will stop flashing after a short period of time and the setup
process is complete.
Note
If the range selected for the actuator is too small, both LEDs
begin to flash again at 4 Hz and the setup procedure must be
repeated with a larger value (min. actuator travel). (Information
regarding actuator travel appears on the actuator name plate.)
Correcting your settings
• If after accepting the initial value for the settings you need to
make a correction, press the reset button and repeat the
setting procedure.
• If you need to make a correction after saving your settings,
you will need to repeat the entire setup procedure from the
beginning.
After commissioning
After commissioning has been performed, it is recommended
that you use the control system to operate the actuator and that
you check the actuator's response and its signaling behavior.
In order for the actuator to go into automatic mode after
commissioning, there must be a 24 V DC-signal on binary input 1
in actuators with active binary input function (standard setting).
If the digital input function is switched off, the actuator will
switch to automatic mode immediately on completion of the
setup process.
