… 7 Commissioning and operation
Manual (MAN)- and Automatic Operation (AUT)
Software version 2.00 and higher
In the manual operating mode (MAN), the actuator solely reacts
upon actuation of either of the two travel buttons on the
commissioning and service field. Any control via the setpoint or
digital input will be ignored.
The operating mode is saved in the non-volatile memory of the
electronic unit. As a result, the actuator will not start up
unintentionally after a power failure.
Activating manual operating mode (MAN) on the
commissioning and service field
• Simultaneously press the Accept buttons 100 % / 0 % (
Figure
20 on page 31,
3
,
5
) for at least 5 seconds.
The LED for the 0%-Position will begin to flash.
Activating automatic operating mode (AUT) on the
commissioning and service field
• Simultaneously press the Accept buttons 100 % / 0 % (
Figure
20 on page 31,

,
5
) for a brief amount of time.
The LED for the 0 %-Position will go out.
Activating the automatic operating mode (AUT) through the
binary input or the graphic user interface
• Apply a +24 V DC signal to binary input 1 and / or select the
AUT operating mode on the graphic user interface.
With the manual operating mode (MAN) activated, the LED for
the 100 % position is continually lit up.

Device setup
Switch to Device setup:
Press and hold down both travel
buttons for approx. 5 s.
After this time, both LEDs will then
flash in sync at 4 Hz.
Approach an end position:
Move to the desired end position by
pressing the travel button.
Both LEDs will continue to flash at 4 Hz
during actuator travel.
Save the initial end position:
Press the 0% or 100% button.
The corresponding LED will flash at
approx. 1 Hz, the other will continue to
flash at 4 Hz.
Save the second end position:
Press the 0% or 100% button.
The related LED will flash at approx. 1
Hz in sync with the first LED.
Special Requirements
Standard operation: MAN / AUT.
The LEDs are not lit.
Travel via the operating button on the
commissioning and service field takes
priority over the control system.
The LEDs are not lit.
Error (both LEDs flashing alternately at 4 Hz)
Press the RESET button to reset the
error messages.
If there are no other errors pending,
both LEDs will go out.
Reset if the operating range is
overshot:
Press and hold down both travel
buttons for 5 seconds and then press
the RESET button.
After approx. 5 seconds, the LEDs will
stop flashing
briefly. After a ‘reset’, the electronic
unit will be in Adjustment Mode!
ECOM Mode
The ECOM688 engineering tool is
used to access the electronic unit.
Both LEDs light up continuously.
