Safety
3. Safety
This chapter contains user safety information.
3.1 Experienced staff
The ’AS-i Safety Output Module with Diagnostic Slave’ must only be installed, op-
erated, and maintained by qualified staff.
Qualified is a person who
• has a suitable technical education
• has been instructed in operating the machinery and has been informed about
the valid safety guidelines by the machinery operator
• has access to the user manual.
3.2 Application area of the device
The VBA-4E2A1A-KE3-ZEL/E2L/SEL module is a decentralized output-module
that safely controls actuators on the AS-i Safety at Work (SaW) safety bus sys-
tem.
In this set-up, a Safety Monitor or a Gateway with integrated Safety Monitor, re-
spectively, controls the VBA-4E2A1A-KE3-ZEL/E2L/SEL .
A special characteristic of this module is its three different kinds of AS-i address-
es:
• safety output
VBA-4E2A1A-KE3-ZEL/E2L/SEL listens to the communication on the safe
address and switches based on these data.
• 4I input slave
One standard AS-i slave (AB slave) for polling inputs I1, I2, I3 and 1.Y1
• diagnostic slave
The standard AS-i slave (AB slave) is used for diagnostic purposes and for
switching under normal operating conditions.
All SaW output modules with the same safe AS-I address switch at the same
time.
The VBA-4E2A1A-KE3-ZEL/E2L/SEL module is certified according to
EN 62 061, SIL3, and EN 13 849, performance level "e".
Warning!
Please read this chapter carefully before using the #variable<produkt_name_kurz>#
in combination with other machine safeguarding components on protected machinery.
Attention!
For protective operation of the module the switches must be in the ON/RUN position.

5. Product Description
This chapter is intended to inform the reader about the special characteristics of
the AS-i Safety Output Module with Diagnostic Slave. It describes the design and
the functionality of the devices.
5.1 AS-i Safety at Work
AS-i Safety at Work combines safe and non-safe data on a bus system. The clas-
sification AS-i Safety at Work identifies the safe data transfer that enables the in-
tegration of safety procedures in an AS-i network.
The components of AS-i Safety at Work conform to EN 50295 and are compatible
with all other AS-i components. Therefore, existing AS-i applications can easily be
extended with safety-relevant functions.
AS-i Safety at Work always requires a Safety Monitor (as a stand-alone device or
integrated into a Gateway), that evaluates the safe signals on the bus, and a safe
AS-Interface bus connection, that enables the transfer of safe signals from safety-
relevant components (AS-i SaW input).
Additionally, decentralized safe AS-I SaW outputs can be added. Controlled by
the Safety Monitor these outputs can be used to safely switch off safe actuators.
Several Safety Monitors and safe input and output slaves can be used on an
AS-i system. At the same time, the Safety Monitors can be parameterized and,
thus, be checked through AS-i and the configuration software.
In order to satisfy the requirements of these safety categories, all peripheral com-
ponents, for instance the Safety Monitors, all safe bus connections, and all con-
nected sensors must satisfy these standards.
5.1.1 Special characteristics of the AS-i Safety Output Module
• Two series connected, self-testing semiconductor switches for safe release
• Two separately drivable standard semiconductor outputs, controlled from the
safe release.
• Four standard inputs
• Supply for in- and outputs from 24 V auxiliary voltage.
• Programming jack
• 2 operating mode selector switches
Warning!
This chapter must be read before installation and operation of the device in conjunction
with other safety components on protected machinery.
Information!
By utilizing AS-i Safety at Work safety requirements according to SIL3, EN 61 508 and
EN 62 061 and as well Cat. 4 and Performance-Level "e" according to EN ISO 13 849
can be satisfied.

6. Maintenance
6.1 Controlling safe shutdowns
The plant safety engineer is responsible for verifying that the AS-i Safety Output
Module with Diagnostic Slave works correctly as part of the safety system.
At least once a year it is necessary to verify the safe shutdown by initiating asso-
ciated safety-related sensors or switchs:
Attention!
Press each safety-related AS-i slave and watch the reaction of the output circuits of the
AS-i Safety Monitor.
Attention!
Check the maximum activated time and the total operating time. These values depend
on the PFD value chosen for the total failure probability. Please refer to the information
in chap. Safety relevant data.
After reaching the projected maximum operating time (three, six, or twelve months) the
entire safety system must be checked for proper operation.
After reaching the projected total usage time (20 years) the device must be checked by
the manufacturer concerning its proper operation.

AS-i Safety Output Module with Diagnostic Slave
Safety Requirements
8. Safety Requirements
• Two semiconductor switches in series are used which issue the safety
release.
• These switches are tested in the unit so that any error which prevents one of
the two semiconductor switches from turning off is detected.
• The two outputs 1.14 ext.out and 2.14 ext.out are fed by the same release
signal. They are not safely isolated from each other.
• If there is no release, both outputs are safety turned off.
• If there is a release, both outputs can be controlled by non-safety signals.
• The return line from the consumers must be connected to the 0 V ext.out ter-
minal on the module and may not be taken directly to the 0 V ext.out of the
power supply.
• There is no cross-connection monitoring between 1.14 ext.out and
2.14 ext.out.
• If two independent, series wired contactors need to by controlled by the
device, you must ensure that the line between the contactors and the device
cannot make a connection to a different potential, so as to prevent undesired
turning on of the contactors.
• Input 1.Y1, just like inputs I1... I3, is a standard AS-i input.
• The external 24 V supply must be provided by a PELV power supply.
