Action

This symbol indicates a paragraph with instructions. You are prompted to perform an action or

a sequence of actions.

2.2 Intended Use

The device can be used as a safety module with safety-related inputs for connecting mechani-

cal contacts, such as emergency-stop switches, and an optional conventional electronic out-

put, e.g., to activate signal lights. When used in this way in conjunction with a programmed AS-

nterface safety monitor, the device allows operation of sensor-controlled personal protective

equipment up to category 4/PL e as per SO 13849-1, or up to S L 3 as per EN/ EC 62061.

The maximum service life of the AS- nterface safety module is 20 years. Replace the device as

a matter of course after 20 years at the latest.

Safety Classification

The module contains two independent, redundant input channels. f both input channels are

used, the module is suitable for use up to category 4/PL e in accordance with SO 13849-1, or

S L 3 in accordance with EN/ EC 61508 and EN/ EC 62061. n this case, the monitor must be

programmed so that dual-channel switching is monitored.

f a single-channel switch is used, the module is suitable for use up to category 2/PL c in accor-

dance with SO 13849-1, or S L 1 in accordance with EN/ EC 61508 and EN/ EC 62061. Only

tested and certified power supplies with safe isolation may be used to supply power. These

power supplies must have PELV voltage in accordance with EN 50295/ EC 62026-2, and a

minimum MTBF of 50 years. The power supplies are designed to exclude a short circuit

between the primary and secondary sides.

Danger!

This symbol indicates an imminent danger.

Non-observance will result in personal injury or death.

Warning!

This symbol indicates a possible fault or danger.

Non-observance may cause personal injury or serious property damage.

Caution!

This symbol indicates a possible fault.

Non-observance could interrupt the device and any connected systems and plants, or result in

their complete failure.

Approvals

The device is approved in accordance with SO 13849-1 and EN/ EC 62061.

2.3 General Safety Information

Always operate the device as described in these instructions to ensure that the device and con-

nected systems function correctly. The protection of operating personnel and plant is guaran-

teed only if the device is operated in accordance with its intended use.

nstallation and commissioning of all devices may be performed only by trained and qualified

personnel.

Only instructed specialist staff may operate the device in accordance with the operating man-

ual.

t is dangerous for the user to carry out modifications and/or repairs and doing so will void the

warranty and exclude the manufacturer from any liability. n the event of any serious errors, stop

using the device. Secure the device against unintended operation. To have the device repaired,

return it to your local Pepperl+Fuchs representative or your sales center.

Only qualified electrical specialists are authorized to perform maintenance work.

Do not open the device.

The device must be installed in a switch cabinet or switch box with a degree of protection of at

least P54.

The operating company bears responsibility for observing locally applicable safety regulations.

2.4 Residual Risk

The residual risk is the potential dangers of the safety system even though the system complies

with all regulations. Note the below instructions.

2.5 Safety onitor Requirements

The device must be used only as intended as a safety-related slave in an AS- nterface segment

with the corresponding AS- nterface Safety Monitor. 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.

Danger!

ncorrect device connection.

Do not use the outputs for safety-integrated functions.

Caution!

Short circuit

f you are not using an available output, make sure that the bare cable end is insulated. Bare

cable ends can be protected by fitting a terminal block, for example.

Warning!

Electrical short caused by moisture

f the surrounding enclosure or switch cabinet is not properly sealed, the safety function may be

lost.

VAA-2E1A-CB10-SJ/E2J-FL, VAA-2E2A-CB10-SJ/E2J-FL

Safety

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 Perfor-

mance Level or Safety ntegrity Level (S L) must, as a minimum, comply with the Performance

Level or S L required by the application.

f a restart interlock is required for the safety function, this restart interlock must be imple-

mented in the safety monitor.

2.6 Cabling Requirements

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

the external cabling and selection of connected switches and/or mechanical contacts are

based both on the level of functionality to be achieved, and on the required category

( SO 13849-1 or EN/ EC 61508).

2.7 Switch or mechanical contact requirements

The switches must be spring loaded. Switches combinations that guarantee an equivalent

safety status (malfunction analysis) can be used.

2.8 Fault Eliminations

Within this device, short circuits on the PCB and within the cable have been eliminated, as

required by SO 13849-2. Maintenance work must include making sure that the individual wire

strands and the device are protected against damage. Route the wire strands as per

EN/ EC 60204-1.

2.9 Transmission Time for Safety-Related Information

Reliable details of the switch-on delay for the device can be found in the data sheet. This delay

affects the switch-off time of the corresponding fail safe circuit.

2.10 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.

Caution!

Protected cable installation

Protect the cable of the safe inputs against mechanical damage in accordance with the require-

ments set out in EN/ EC 60204-1.

f there is a risk of tampering, attach terminal blocks or field-attachable connectors such that

they are inaccessible to operating personnel.

3 Product Description

3.1 Function

The VAA-2E1A-CB10-SJ/E2J-FL is an AS- nterface safety module with two safety-related

inputs and one conventional output. The VAA-2E2A-CB10-SJ/E2J-FL is an AS- nterface safety

module with two safety-related inputs and two conventional outputs. A dual-channel mechani-

cal switch can be connected to the two safety-related inputs on both devices, or a single-chan-

nel mechanical switch can be connected to each device. The output(s) is/are conventional,

non-safety-related electronic outputs that can have a total load of 100 mA.

Figure 3.1 Example of an AS- nterface system with safety module and emergency-stop button

The module is suitable for the decentralized connection of switches in very confined spaces.

The connection to the AS- nterface cable and the connection of the inputs and the output(s)

involves bare cable ends.

Each channel has an LED mounted on the top side of the module to indicate the current switch

state. There is an LED for monitoring AS- nterface communication and for indicating that the

module has the address 0. n the event of a communication failure, the outputs are discon-

nected from the power supply. .

3.2 Slave Profile

The modules have the following profile:

The data value is transmitted as defined by AS- nterface profile 7.B.
