AS-Interface customized enclosures and front panel modules

■Overview

Customized solutions for linking command devices to AS-Interface permit the configuration of command devices to be selected as required. In addition to the enclosures, the AS-Inter- face front panel module provides a solution for SIGNUM 3SB3 Command Devices mounted in front panels.

■Design

AS-Interface enclosure

The enclosures with two, three, four and six command points are

equipped with a 4I/4O slave. Up to four inputs (switch contacts)

and four outputs (lamp holders) can therefore be connected to

them. A second slave can be mounted on enclosures for four

and six command points. Addressing is via the AS-Interface

connections or via the built-in addressing socket. An external

supply voltage is not required.

For enclosures with EMERGENCY STOP, the EMERGENCY

STOP actuator can be wired conventionally or alternatively using

the AS-Interface F adaptor.

With conventional wiring, interrogation can be performed via AS-

Interface. In this case, a second slave cannot be mounted on the

enclosure for four command points.

In the case of conventional wiring of the EMERGENCY STOP, up

to three switch contacts can be selected for the EMERGENCY

STOP; if the EMERGENCY STOP is scanned via AS-Interface,

two contacts are possible.

If the EMERGENCY STOP is wired via the F adaptor, the safe

module is mounted above or to the right. The AS-Interface cable

is then looped through to supply the non-safe command devices

of the enclosure. EMERGENCY STOP via an F adaptor is only

possible for enclosures for three, four or six command points.

The following methods can be used for connecting the AS-Inter-

face cable:

• Terminal for shaped AS-Interface cable. Contact is made with

the cable using the insulation piercing method and it is routed

externally past the enclosure.

•Cable gland for the shaped AS-Interface cable or round cable. The cable is inserted into the enclosure.

•Connection via M12 connectors

•In the case of enclosures with EMERGENCY-STOP via the AS- Interface F adaptor, the cable is connected using the terminals mounted on the F adaptor for the shaped AS-Interface cable. The cable is routed externally past the enclosure.

Typical connections

If not all the inputs and outputs of the slave built into an enclo- sure are used, the spare inputs and outputs can be routed to the outside via an M12 socket at the top and bottom of the enclo- sure. The pin assignment required for the M12 socket must then be specified on the order supplement (see section Options).
