Manual (Man)- And Automatic Operation (Aut) - ABB EBN861 Operating Instruction

EBN853 / EBN861 ELECTRONIC UNIT | OI/EBN853/EBN861/EX-EN REV. C

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
3, 5
17 on page 32, ) 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
3, 5
17 on page 32, ) 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.

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