■ Overview
Various AS-i add-on modules are available for communication
of the 3RA6 compact feeder with the control system using
AS-Interface:
• Standard version
• With two local inputs
• With two free external inputs
• With one free external input and one free external output
• With two free external outputs
• For local control
The AS-i add-on modules can be combined only in connection
with compact feeders with a rated control supply voltage of
24 V AC/DC.
AS-i add-on module for on-site controller
With this new module it is also possible for the connected
compact feeder to be operated directly using simple switches,
i.e. without recourse to AS-i Communication, if required.
"Automatic" mode
NC contacts can be connected to the inputs Y2 and Y4 through
the local terminals on the AS-i add-on module. If the "+" connec-
tions are connected simultaneously to both local inputs, the
AS-i add-on module will be in "Automatic" mode, i.e. it will com-
municate with the control system through AS-Interface.
On-site control
Opening the two inputs Y2 and Y4 will result in the direct discon-
nection of the compact feeder. Operation through AS-i Commu-
nication is ended and the compact feeder can now be switched
on and off directly using NO contacts (one NO contact per direc-
tion of rotation on the reversing starter).
"LED AUX Power" must light up green, the 24 V DC supply must
be assured and the AS-i control supply voltage must no longer
be applied.
Resetting to "Automatic" mode
Simultaneous application of a "1" signal at the local inputs. The
availability bit DI 0 is switched to a "1" signal.
If AS-i Communication is reset, the motor is first switched off and
then on again when requested by the control system.
