System Description

1.1 What is the Actuator-Sensor Interface (AS-i)?

What is AS-i? When a system is installed, the input/output modules are normally installed

centrally in the programmable logic controller If inputs and outputs are made at long distances from the programmable logic controller, there may

be long runs of cabling which are not immediately comprehensible, and tromagnetic interference may impair reliability

elec-In such systems, we recommend you to use the AS-i.

The AS-i is an open bus system, that means:

• The controller CPU with the AS-i master is located centrally

• The I/O (input/output) system operates locally in a distributed fashion

What does AS-i

consist of?

The actuator-sensor interface consists of active and passive nodes, socalled master and slaves Up to 31 slaves in any network structure can be connec-ted to a master

AS-i slaves and AS-i master are interconnected by a 2-wire line used to mit both data and power to the slave electronics

trans-AS-i Master and

AS-i Slave

AS- master exchanges data with the AS-i slave and monitors the bus

The I/O devices are connected as AS-i slaves DP slaves process data locally from the sensors and signal control elements in such a manner that they can

be transferred over the AS-i bus

Installation

2.1 Installing the Compact Starter

Installation position Compact starters DS2DI and RS2DI can be installed on a vertical wall with

the following maximum inclination angles:

• 22,5 degrees forward or backwards and/or

• 90 degrees to the left or right

Compact starters EDS2DI and ERS2DI can be installed in any position

Installation These installation instructions apply both to the electromechanical and the

electronic compact starter Proceed as follows:

You need For fixing the mounting plate you need:

• M5 cheese-head screws to ISO 1207/ISO 1580 (DIN 84/DIN 85) or

• M5 cheese-head screws with hexagon socket to DIN 912,

Mounting plate The diagram below shows you the dimensions and positions of the fixing

screw holes for the mounting plate Fix the compact starter onto it

Compact starter The diagram below is a dimension drawing of the compact starter 

The overall height is not changed by the mounting plate because the mounting plate is "recessed" into the compact starter

3.1 Rules for Wiring

WarningDangerous high voltage! Take care to avoid electric shock and injuries from burns Always deenergize the system and the device before carrying out any work

Selecting the motor

connecting cables

The core cross section of the motor connecting cables must match the given environmental conditions The cross section is governed by:

• the nominal current set on the unit,

• the method of cable laying,

• the ambient temperature,

• the insulation material of the motor connecting cable (PVC, rubber)

For PVC motor connecting cables laid in cable ducts, the following maximum current carrying capacities apply according to environment temperature:

ImportantMax motor connection cabel length 30 m

Rules for flexible conductors Data

with braking contact

The 400 V power supply for the motor and the 24 V DC power supply for the brake are fed to the load through a common cable and connector There is a danger of voltage overspill if the cable is flattened Do not therefore connect loads with degree of protection "extra-low voltage" to the braking circuit

In order to avoid voltage overspill in case of fault the supply voltage for the brake must be drawn from a power supply unit with safe electrical isolation (PELV)

3.3 Compact Starters with a 24 V DC Braking Contact

That is why loads with degree of protection “Extra-low voltage“ must not be connected to the brake circuit

As safeguard against “accidental voltage transfer“, the supply voltage for the brake must be taken from a separate power supply unit with safe electrical isolation (PELV)

The brake must not be fed from the power supply unit for the 24V auxiliary

circuit (AUX PWR, black cable)
