■
Overview
With AS-Interface enclosures, distributed SIRIUS ACT push-
buttons and indicator lights can be quickly connected to the
AS-Interface communication system. Using suitable compo-
nents you can make your own enclosures with integrated
AS-Interface or flexibly modify existing enclosures.
Enclosures for AS-Interface
Enclosures
Color of enclosure top:
• Gray, RAL 7035
• Yellow, RAL 1004 for EMERGENCY STOP
Color of enclosure base:
• Black, RAL 9005
Equipping with AS-Interface slaves
The following slaves are available for connecting the command
points:
• Slave in A/B technology with 4 digital inputs and 3 digital
outputs (4 DI/3 DQ)
• Slave with 4 digital inputs and 4 digital outputs (4 DI/4 DQ)
• F slave with 2 safe inputs for EMERGENCY STOP mushroom
pushbutton (2 F-DI), also with integrated red LED for the
illuminated EMERGENCY STOP mushroom pushbutton.
The following table shows the maximum number of slaves
possible:
Connection
One set of links is required in each case to connect a slave to
contact modules, LED modules, and the connection element.
The connection elements are mounted in the front-end cable
glands and are used to connect the AS-Interface or bring
unused inputs or outputs out of the enclosure.
For connection to AS-Interface, the following options are
available:
• Terminal for shaped AS-Interface cable. The cable is
contacted by the insulation piercing method and routed past
the enclosure on the outside (possible only with plastic
enclosure).
• Cable gland for the shaped AS-Interface cable or round
cable. The cable is routed into the enclosure (preferable for
metal enclosure).
• Connection using M12 plug.
If less than all inputs/outputs of the installed slaves in an enclo-
sure are used for connecting the command devices, free inputs
and outputs can be routed on request to the outside through an
M12 socket on the top or bottom side of the enclosure.
To supply inputs with power, the S+ connection of the slave must
be assigned to the socket, for outputs the OUT– connection
must be assigned. Addressing is performed using the
AS-Interface connections or the integrated addressing socket.
An external power supply is not required.
Enclosures with standard fittings
Enclosures with standard fittings are available with:
• 1 to 3 command points
• Operational voltage through AS-Interface (approx. 30 V)
• Vertical mounting type
• Plastic enclosures are equipped with plastic actuators
and indicators, metal enclosures are equipped with metal
actuators and indicators
The enclosures without EMERGENCY STOP each have one
module with 4I/3O; the enclosures with EMERGENCY STOP
mushroom pushbuttons have a safe AS-Interface slave inte-
grated in the enclosure. Enclosures with EMERGENCY STOP
mushroom pushbuttons are fitted with two NC contact modules,
which are wired to the safe F slave.
The contact modules and LED modules (with spring-type termi-
nals) of the command devices and the AS-Interface slaves are
mounted in the base of the enclosure and connected using
cables. The plastic enclosures are designed with a connection
for the AS-Interface flat cable (the cable is run along the outside
of the enclosure). For metal enclosures, the AS-Interface cable
is run inside the enclosure.
The enclosures with EMERGENCY STOP mushroom push-
buttons are also available with an M12 connector.
Customized enclosures (selection by configurator)
To order customized 3SU18 AS-Interface enclosures with
pushbuttons and indicator lights, the configurator must be used
to select the fittings. An electronic order form will be generated
for the options.
