Overview
The enclosures can be equipped with command devices as
required for customer-specific solutions to connect command
devices to the AS-Interface.
Customer-specific enclosures are available with 2 to 6 command
positions.
One command position comprises:
7 1 actuator or indicator
7 Up to 3 contact blocks or up to 2 contact blocks
+ 1 lampholder
7 1 inscription label
For plastic enclosures the command positions are equipped as
standard with plastic actuators and indicators, for metal enclo-
sures they are equipped with metal actuators and indicators.
For the equipping of the command positions, see Options.
Installation of AS-Interface slaves
The following slave types are available for connecting the
command positions:
7 Slave in A/B technology with 4 inputs and 3 outputs
7 Slave with 4 inputs and 4 outputs
7 F slave with 2 safe inputs for EMERGENCY STOP
The following table shows the maximum number of equippable
slaves:
1) For metal enclosures with 4 command positions,
only 1 x slave 4E/4A or 4E/3A is possible.
Connection
The customer-specific enclosure is delivered fully equipped and
wired. For connection to the AS-Interface bus there is a choice
of the following options:
7 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).
7 Cable gland for the shaped AS-Interface cable or round
cable. The cable is routed into the enclosure (preferable for
metal enclosure).
7 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. The re-
quired pin assignment of the M12 socket must be entered in the
order documentation (see Options).
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.
EMERGENCY STOP
On enclosures with EMERGENCY STOP, the EMERGENCY
STOP actuator can be wired conventionally or by way of a safe
AS-Interface slave.
With conventional wiring of the EMERGENCY STOP, up to three
switching contacts can be selected for the EMERGENCY STOP:
if the EMERGENCY STOP is scanned via AS-Interface, two con-
tacts are possible for the safety circuit.
With conventional wiring, the scanning of one EMERGENCY
STOP contact block through AS-Interface is possible.
Selection and ordering data
Selection and ordering of the customer-specific enclosures is
carried out directly via the configurator for pushbutton units and
indicator lights. For further information, see "Options".
Options
To order customized AS-Interface enclosures with the 3SB3 con-
trol devices, use the 3SB/3SF configurator to select the blocks
for equipping. An electronic order form will be generated for the
additional options. The configurator is available in the electronic
catalog CA 01 on CD-ROM or DVD or in the online catalog (Mall)
on the Internet:
https://mall.automation.siemens.com
Select the configurator for "3SB3, 3SF5 pushbutton units and
indicator lights" from the configurator list.
Start the configuration with the "Execute" list entry and choose
the "Customer-specific ASI enclosures".
The list price of the complete enclosure is generated in the
configurator for the customized equipment.
Please send the resulting electronic order form along with your
order to our Competence Center at
sirius-attach.aud@siemens.com
If you are unable to access either catalog, please contact our
Technical Assistance.
