8540643 - 26/08/2016 Rev.13
K1K2 FEEDBACK input
Using the K1 and K2 auxiliary safety contactors with guided contact
safety type, it is necessary to connect the +24Vdc to the
through the series of the K1-1 e K2-1 N.O. control
contacts. The control of the correct switching of K1 and K2 is
performed with a delay of 300ms after the real command.
When the K1-1 e K2-1 N.O. control contacts are not used (or no control
is provided) it is mandatory to connect the terminal 20
(
) to the terminal 21 (
).
SYSTEM STATUS output
The SYSTEM STATUS output reports exactly the output safety relays status :
When the output relays are opened, the SYSTEM STATUS reports 0VDC.
When the output relays are closed, the SYSTEM STATUS reports
+24VDC.
INSTALLATION AND ELECTRICAL CONNECTIONS
Install the AUS XM control unit in an environment with a protection rating of
at least IP54.
If more modules AUS XM must be installed in the same board panel, in order
to avoid overheatings, maintain between them one minimal distance of 2cm.
The AUS XM control unit must be supplied with a 24Vdc
20.
The external power supply must comply with the standard EN 60204-1.
During the installation of the AUS XM control unit be sure to avoid short
circuits between the contacts 17 and 18.
Characteristics of the output circuit.
For the output circuit, the control unit uses two guided contact safety
relays.
These relays are rated by the manufacturer for voltage and current
values above those indicated in the technical data; however, to assure
correct insulation and to avoid damage or premature aging, protect
each output line with a 4A slow-blow fuse and check that load
characteristics comply with the indications given in the table below.
Minimum switching voltage
18 Vdc
Minimum switching current
