2 Safety

2.1 Intended Use

When used as intended, the AS- nterface safety module allows the operation of sensor-con-

trolled personal protective equipment up to category 4 and PL e as per SO 13849 or up to S L

3 as per EN/ EC 61508 and EN/ EC 62061 in combination with an appropriately programmed

AS- nterface safety monitor. The safety level of the application is determined either via a risk

analysis, e.g., in accordance with EN 1050, or is taken from a C standard.

2.2 Peripheral Re uirements

Safety Monitor Re uirements

The module must only be used as a safety-related slave in an AS- nterface segment with the

corresponding AS- nterface safety monitor as intended. The AS- nterface safety monitor must

meet the requirements of the "Specification of Safe AS- nterface Transmission" system specifi-

cation (version 2.01) dated 05/12/2000.

To evaluate a safety-related function in accordance with a safety standard, all components

found in the function must be evaluated in accordance with this standard.

The wiring and programming of the safety monitor determine whether or not the required safety

function performs correctly. This also applies to the required safety response after a code fault

or failure (see also safety monitor documentation). The safety function (including all safety-

related sensors) must be checked prior to initial commissioning. The safety monitor PL cate-

gory or S L must, as a minimum, comply with the PL category or S L required by the applica-

tion.

Cabling Re uirements

The requirements set out in EN/ EC 60204-1 or similar must always be observed. The require-

ments for the external cabling and selection of connected sensors are based both on the level

of functionality to be achieved, and on the required category ( SO 13849-1, EN/ EC 61508, or

EN/ EC 62061).

Switches or Mechanical Contacts

The switches must be positive opening. Combinations of switches that provide an equivalent

level of safety (fault behavior analysis) can be used.

2.3 General safety instructions

The module can only be operated by trained professionals in accordance with the available

instruction manual.

Connecting modules and performing maintenance tasks while the devices are connected to a

power source must only be performed by trained electrical specialists.

f malfunctions cannot be eliminated, the module must be taken out of operation and protected

from being inadvertently placed back in operation.

Repairs must only be performed directly by the manufacturer.

Making changes to or tampering with the device is not permitted and will render the warranty

void.

When operating the device, care must be taken to ensure that the requirements for installation

of a housing in P20 are also maintained.

Danger!

Any type of operation other than what is described in the instructions places the safety and

functionality of the module and connected systems in question.

Safety

2.4 Transfer time of the safety-relevant information

The transfer time depends essentially on the monitor. The corresponding documentation and

the switch-off times of the actuators must be observed.

2.5 Probability of Failure on Demand Calculation

To calculate the probability of dangerous failure on demand (PFD) of a safety-related function,

the PFD values for all components used within this function must be taken into consideration. n

the case of dual-channel applications, the AS- nterface safe input module does not significantly

contribute to the PFD or PFH (probability of dangerous failure per hour) of the overall system.

The PFD and PFH values for single-channel application can be found in the data sheet. The

PFD or PFH values of the other components, in particular the safety monitor, can be found in

the relevant documentation.

Note

The plant management is responsible for heeding local safety regulations.

3 Product Description

3.1 AS-Interface Safety at Work VAA-2E-KE1-S

The VAA-2E-KE1 is an AS- nterface safety module with two safety-related inputs. A dual-chan-

nel mechanical switch or single-channel mechanical switch can be connected to the two

inputs. The housing is only 22.5 mm wide and 48.5 mm tall and takes up little space in the

switch cabinet. A snap-on function mounts the module onto the 35 mm mounting strip in line

with EN 50022. An addressing socket is integrated in the module.

The connection is made via plug-in terminals. A four-way (black) terminal block is used for the

inputs. The AS- nterface is connected via a two-way (yellow) terminal block. Each channel has

an LED mounted on the top side of the module to display the current switching status. There is

also an LED for monitoring AS- nterface communication and to display that the module has the

address 0.

f single-channel positive-action mechanical switches are connected, the module can be

graded up to category 2 / PL c in accordance with EN SO 13849-1 if wired appropriately and

the switch is selected accordingly. f a dual-channel positive-action mechanical switch is con-

nected, the module can be graded up to category 4 / PL e in accordance with EN SO 13849-1

if wired appropriately and the switch is selected accordingly. As per the approval in line with EC

61508, a Safety ntegrity Level of up to S L 3 can be reached. Both module inputs are occupied.

The two channels belonging to the mechanical switch are monitored for crossed circuits. An

LED displays the AS- nterface voltage.

3.3 Interface Properties

AS-Interface

The KE1 series module is connected to the AS- nterface via removable terminals. The cable

must satisfy the minimum requirements for AS- nterface, e.g., AS- nterface ribbon cable VAZ-

FK-S-YE.

Inputs

General

The switches are connected to removable terminals. One or more mechanical switches can be

connected in series per channel.

Figure 3.1 Two mechanical switches (or one dual-channel switch)

f only one single-channel switch is to be used, input 1 should be used in this case. f input 2 is

not connected, it must be bridged.
